1.3 Description of safety provisions
As a standard the S piral Elevator is not provided with control or any safety
provisions. Before putting the Spiral Elevator into service some safety
provisions are to be incorporated. The purpose of these safety provisions
is to protect the user , the product and the S piral Elevator against un desired
situations (damage). If these safety provisions are not incorporated it will
invalidate the warranty.
The table below gives a general description of the safety provisions
required. Only technically qualified persons should work on the settings of
the safety provisions!
The safety provisions listed in the table are a general gu ide only . The actual
safety provisions to be used must be determined by relevant risk
assessment of the overall system.
Control Remark
Emergency stop switch Each Spiral Elevator is to be provided with one or more emergency stop
switches that can be operated within reach of the user. The emergency
stop switch must make sure that the input and output conveyors or
machines are switched off simultaneously.
Motor protection The technical specification of the Spiral Elevator is, among other things,
geared to the load given in the technical specification, quotation or
drawing.
Should the Spiral Elevator (gear motor) become overloaded, this should be
detected by the motor protection in the control system. Without this
protection there is a chance that the gear motor or other components of the
Spiral Elevator will be damaged and this damage will not be covered by the
warranty.
Motor isolation Means of isolating the motor from the power supply must be provided and
within close proximity to the motor.
Where the possibility exists for oversize product to enter the Spiral Elevator
it is recommended to install a detector prior to the Spiral Elevator and use
this to stop the elevator thus preventing damage from occurring.
Note! If an oversize product jams in the Spiral Elevator it may
damage the unit.

Frame The basic frame of the Spiral Elevator consists of a central column (1), an
upper end (2), a lower end (5) and a frame (4) that is attached to the floor
surface. The materials of these components depend on the configuration
selected. Both the upper end and the lower end may function as the input or
output part of the Spiral Elevator.
3. Conveyor
chain (slats)
The conveyor chain consists of a chain and conveyor chain / plates with guide
rollers. The top of the chain has a high friction material to ensure no sliding of
products on the chain. The conveyor chain rot ates in a spiral fo rm around the
central cylinder and is guided on the plastic slide strips. The con veyor chain is
driven by the gear motor.
Gear motor The gear motor is mounted on the drive shaft of the conveyor drive end.
The standard Spiral elevator is not delivered with a gear motor. However a
gear motor may be added as part of the supply contract.
Suggested Gear motor specifications can be obtained from the FlexLink
Configurator or from FlexLink.
The gear motor requires a Torque arm kit and a Absorber kit to prevent rota tion
and two types are available as follows:
• For SA37 type gear motors, Torque arm kit = 5057039
- Absorber kit = 5113736
On the driving shaft a sprocket wheel has been mounted th at is connected to
the chain of the conveyor chain.
Guide rail,
optional
The guide rail ensures that the products follow the conveyor chain and prevent
them from falling off the Spiral Elevator.

Introduction
In most cases the Spiral Elevator is integrated in to a system. The input /
output side of the S piral Elevator is determined dependent on the system.
In the following example, it is assumed that the input is at the lower end of
the Spiral Elevator and that the product will bridge a dif ference in height in
order to continue the required transport on the output.
Input end Transport of Products Output end
1 The product is transferred onto the input of the Spiral Elevator.
The gear motor drives the conveyor chain with the required
speed.
2 Subsequently, the product on the conveyor chain will travel
around the Spiral Elevator and bridge the height difference
between input and output.
3 When the product arrives at the output of the S piral Elevator it will
continue along the system. The conveyor chain returns in the
underside of the Spiral Elevator to the input position.
Page 20 of 68
5478EN-3
Introduction
3.4 Control units
As a standard the Spiral Elevator is delivered without any control system.
When a Spiral Elevator is supplied without control it is the responsibility of
the system integrator / installer to design a suitable control system.
It is preferable to install an isolating switch for the gear motor and it should
be of a type able to be padlock off.With this switch the power to the gea r
motor can be switched / locked off in order to ensure safe working on the
Spiral Elevator.
The designer of the Control System should ev alu at e th e requ ire m en ts of
other devices such as Emergency stops etc. in order to provide a safe
working system.

4.1 Preparation
Before starting the unloading, good preparation is required.
The appropriate devices must be available.
A series of checks must be made to the Spiral Elevator and these should
be done:
• Before off-loading from the delivery vehicle.
• Immediately after off-loading.
• Immediately after unpacking.
Any damage must be detailed on the delivery note before signing for
acceptance of delivery and also notified to FlexLink in order to possibly
progress any warranty claim.
Details of the dimensions and technical specifications are available on one
or more of the following:
• Technical specification
• Quotation
• Drawing
• Order
Any deviation must be notified to FlexLink immediately.

Unload the Spiral Elevator
4.2 Unloading instructions
Initially the Spiral Elevator should be removed fr om the delivery vehicle by
lifting the Spiral Elevator complete with any pallet base and / or packing
materials.
Before starting unloading, all fastening means (securing belts, screws, etc.)
that secure the S piral Elevator onto the transpor t vehicle must be removed.
It is preferable to move the Spiral Elevator complete with any pallet base
and / or packing materials to an area near to the final position and then
unload the spiral elevator and place it directly on the floor whilst taking care
not to cause any damage to the painted surfaces.
The Spiral Elevator ma y be delivered horizontally or vertically dependent
on the dimensions.
If the Spiral Elevator is delivered vertically it can be lifted using a ForkLift
truck under the base frame or by using a sling and suitable eye bol t in the
top of the central column.
If the Spiral Elevator is delivered horizont ally , it can be lifted using a ForkLift
truck with forks spaced wide apart and in serted under the horizontal central
column. Soft packing should be used between the forks and the central
column to avoid damage and marking. Care must be taken to avoid the
Spiral Elevator rolling whilst on the forks. Alternatively slings can be used
and attached to two positions around the central column.

4.2.1 Erecting the Spiral Elevator
This section is for taller Spiral Elevators which are transported in the
horizontal position.
When putting the unit upright or when moving the Spiral Elevator make
sure that the floor is level and clean and has sufficient load carrying
capacity.
It is generally safer to move the Spiral Elevator to a position close to the
final area with the Spiral Elevator remaining on the delivery packing (where
applicable).
When the Spiral Elevator is near to the final position it can be put upright.
Dependent on the situation, the Spiral Elevator can be raised to upright
using a hoist, a crane or a forklift truck.
Device(s)
Hoist Crane Open-end spanner
. Note! Make sure when raising to upright, that there is enough
space / height to put the Spiral Elevator upright.
Page 24 of 68
5478EN-3
Unload the Spiral Elevator
The following describes a typical method utilizing a hoist
• The hoisting device is to be fastened to the cylinder at the top of
the Spiral Elevator. Whilst hoisting, the hoist should be well fixed
and must not be able to ride/shift away unexpectedly.
• Raise the to p of th e Spiral Elevator around 200mm an d sto p .
• Remove the frame with feet which is temporarily mounted to the
Spiral Elevator column top.
• Raise the Spiral Elevator until lifted completely from the floor an d
in the vertical position. T ake care not to put excessive side load on
the feet to avoid bending or damaging them
. Note! Be aware that the Spiral Elevator may tip at the moment it
is near to the upright position. Make sure there are no persons
near the Spiral Elevator!
• Remove feet from the now horizontal position and re-fit in to the
other holes in the frame to have the feet in the vertical position.

the Spiral Elevator column . Att ach the stay bracke ts between the
Spiral Elevator column and the bottom frames.
• Remove feet from the now horizontal position and re-fit in to the
other holes in the frame to have the feet in the vertical position.
• Check all bolts for the lower frames, feet and stay brackets are in
place and secure.
• Lower the Spiral Elevator down on to the floor .
• Move the Spiral Elevator in to final position taking care not to place
undue side load on the feet to avoid damage. If the S piral Elevator
is moved using a ForkLift truck or Pa llet Truck, great care must be
taken due to the height of the S piral Elevator to ensure that it does
not topple over.
• The feet can be adjusted to give the correct height. Make sure all
four feet are adjusted evenly.
. Note! Carry out these operations calmly in order to be able to
carefully monitor any movement of the Spiral Elevator.

5.2 Assembly
This paragraph describes a number of ope ra tions for Spiral Elevators that
are not delivered fully assembled. Af ter having finished mounting the S piral
Elevator, the Spiral Elevator can be integrated (Section 1.4) in a system.
5.2.1 Motor
The gear motor may be delivered separately with the Spiral Elevator and
then has to be mounted on site.
First check if all the required parts are present:
• Gear motor
•Grease
• Torque arm
• Key for shaft
• Fasteners (screw and washer)
The key and torque arm fastening to the frame may be pre-assembled.
The required tools are:
Open-end spanner Ring spanner Internal spring pliers
Procedure:
• Determine the installation orientation of the gear motor.
• Apply installation grease on the shaft to slide the gear motor onto
the shaft easier and prevent any fretting corrosion .
• Attach the torque arm to the gear motor with the appropriate
fixings.

5.2.2 Mounting Guide rail components
The basic Spiral Elevator does not include guide rail or br ackets. Along the
sides of the conveyor track are M8 tapped holes typically every 45º to allow
brackets to be attached.
The following describes how a typical FlexLink Guide Rail Bracket system
can be used on the Spiral Elevator.
For final detail of the optimum guide rail and bracke t ar ra ngemen t consult
the Spiral Elevator supplier or FlexLink.

Mounting, installation, adjustment
Procedure for fitting a typical guide rail
Attach the Guide Rail Brackets to the frame.
If an offset has been chosen, any dist ance piece has to be placed between
the frame and the Guide Rail Bracket.
The bolts used to attach the b racket s to the conveyor side s should be M8.
The length of bolt depends upon the guide rail bracket arrangement used,
but should not protrude in to the beam profile by more than 10mm.
With the brackets in place, the guide rail profile can be mounted to the
brackets and clamps.
Figure 8 Connection mounting bracket
If the guide rail is to be FlexLink polyethylene, XLRS 3x15 P type then to
ensure rigidity at the ends it is suggested to pre-bend a 150 mm long and
10x10 mm metal bar or an Ø10 mm met al rod to the radius of the guide ra il
and insert it in the guide rail at each end.
Make sure that there is a smooth connection b etween the g uide rail joint s,
to ensure product passes along the guide rail un-hindered.

5.3 Validation
Initially the validation checks should be for visual condition and
dimensions.
Subsequently a short test run should be made with the S piral Elevator in an
un-loaded condition.
5.3.1 Dimension check Spiral Elevator
The technical specification and / or relevant drawing can be used for the
dimension check.
5.3.2 Adjusting and setting the Spiral Elevator
Before the start of the test run make visual checks for jammed parts or
items touching the Spira l Elevator chain links and stop immediately if any
exist.
During the test run pay attention to the correct rotation direction of the
conveyor chain and look at the behaviour of the conveyor chain and the
operation of the drive. The chain should move evenly and without undue
jerking motions.
It is not recommended to make a test run with the machine while the safety
provisions have been deactivated or guards removed. Make sure that the
operation is as safe as possible and that there are no unauthorised persons
near the Spiral Elevator.
If during the test run abnormal sounds are heard or if there is an impression
that other irregularities occur, immediately switch off the Spiral Elevator
then investigate and remedy the cause. The checklist in section 5.6 and the
troubleshooting list in section 6.3 may be of assistance.
If the problem cannot be solved, please contact the supplier for advice
before continuing the integration.
If the initial test above is OK, then the following test procedure may be
followed.

5.4 Integration in a (transport) system
The Spiral Elevator is a machine that is integrated in a system of
conveyors. This means that an input and output are to be connected to it.
If the Spiral Elevator is to be fitted into an existing situation, this usually
gives more problems with the installation than in a completely new
situation.
5.4.1 Frequency control
The operating conditions are optimal when the speed of the S piral Elevator
is equal to the speeds of the in-feed and out-feed conveyors or machines.
If a speed difference does exist this can lead to product twisting at the
transfers and wear of the high friction conveyor plates.
If there are speed differences which are unavoidable, these should be kept
bellow 15% and the preferred arrangement is as follows:
• Spiral Elevator up to 15% faster than in-feed conveyor or machine
speed.
• Out-feed conveyor or machine speed to be up to 15% faster than
Spiral Elevator.
The speeds can be tuned by using a frequency controller within the control
system if desired.
If a frequency controller is used for the speed control, ramp-up and rampdown settings should be set such that the Spiral Elevator chain does not
'snatch' or 'jerk' on starting or stopping.
. Note! For the correct setting of the frequency controller the
technical specification supplied with the unit should be followed.

5.5 Setting of the Spiral Elevator
The mechanical and control setting fo r the S pira l Elevator need to be done
correctly, with particular regard to the ends and transfers to ensure good
operation.
5.5.1 Mechanical
Mechanically there are a number of items which can be set for the Spiral
Elevator. The general items are detailed below .
Tools
No. Component Setting / Remark
1. Height setting Spiral Elevator The adjusting feet can be used to set the Spiral Elevator
to the correct height. If necessary, the connecting
conveyors should be adjusted to this as well.
It is not possible to change the difference in height
between the lower and upper ends after the Spiral
Elevator has been manufactured (i.e. the pitch between
turns are fixed).
2. Guide rail, input and output
(optional)
The guide rail width setting may be able to be adjusted at
infeed and outfeed ends of the Spiral Elevator in order to
align with the feeding and receiving conveyor systems.
This may depend upon which guide rail and b rackets are
fitted.
It may be possible to 'flare out' the guide rails at the in-feed
end of the Spiral Elevator

system used to operate the Spiral Elevator. .
No. Component Setting Remark
1. Frequency control
(where fitted)
15% The speed difference of the feeding conve yo r to th e
Spiral Elevator or the Spiral Elevator to the receiving
conveyor should generally be below the setting value.
This is to avoid product twisting at the transfers and
excessive slipping of the product on the conveyor or
Spiral Elevator chain.
2. Emergency stop switch Direct The Spiral Elevat or sho uld be protected via an
emergency stop circuit, such that if the relevant
emergency stop button (or other) is activated, all power
is removed from the Spiral Elevator gear motor,
following which the Spiral Elevator may overrun a little
(depending upon speed).
The full details of the emergency stop circuit and
procedure must be evaluated by the persons
responsible for designing the control system.
3.a. Start / S top via 'Direct on
Line' control
3.b. Start / Stop via

5.6 Test run - partially loaded
In this paragraph the Spiral Elevator will be checked in a semi-loaded
condition with all safety provisions activated. If during the test run any of
the following situations occur, the test must be stopped and the
Spiral Elevator must not be tested further until the issue has been solved.
• Irregular sounds
• Other irregularities / anomalies
• Spiral Elevator does not meet specifications
• Some of the product do not fit on the Spiral Elevator
• Product become stuck or slip
Carry out the check
Initially start the Spiral Elevator with no product loaded and conduct the
items in the checklist.
Then gradually add product to the system up to 50% of the specified feed
rate as detailed in the technical specification or quot ations and conduct the
items in the checklist again.
The gradually add more product to the system up to 1 00% of the specified
feed rate as detailed in the technical specification or quotations and
conduct the items in the checklist again.
If during any of the tests problems are detected, the Spiral Elevator must
be stopped and the problem investigated / remedied and then the tests
restarted.
Check Spiral Elevator
Below is the checklist detailing the main items to check on the
Spiral Elevator when making the test runs.

6 Technical maintenance
Technical maintenance is an important part of this manual.
Good maintenance will prolong the life of the Spiral Elevator and help to
reduce any costs resulting from breakages or downtime.
This section includes a troubleshooting list in section 6.3 and a
maintenance schedule in section 6.4.
Before any maintenance functions are carried out on the S piral Elevator the
power supply to the gear motor must be safely isolated.
6.1 Check and control procedures
6.1.1 Checking conveyor plates
As a result of products becoming jammed the conveyor plates may partly
break off or be pushed from the conveyor chain.
If missing or broken conveyor plates are detected, these are to be
replaced.
Figure 9 Conveyor plate broken
Created by EBCCW 00:06
5478EN-3
Dirt or product labels sticking to the conveyor plates may also make the
plates break or become loose. It is therefore strongly recommended to
regularly check and clean the Spiral Elevator.
Page 43 of 68
Technical maintenance
6.1.2 Checking chain tension and chain stretch
The conveyor chain of the Spiral Elevator must have the correct tension.
If the tension is not correct, the following may occur:
• Chain runs off the sprocket (jumps a cog).
• Conveyor plates grab into the return track causing them to break
or become loose from the chain.
• Excessive wear of the end sprocket caused by too high tension.
In order to prevent these problems, it is necessary to regularly check the
chain tension. This can be done by following the procedure below.
Procedure to check chain tension
• Make sure that the main switch has been switched off, and safely
isolated.
Figure 10 Distance check
• Measure/mark a 500mm section of the conveyor chain near to the
lower end. Then compress and stretch this 500 mm section of the
conveyor chain and measure the variation in the length.
• If this variation is more than 38.5 mm (1.52") this indicates that at
least one conveyor link can be removed from the chain. On the
side of the conveyor there may be a graduated scale with up to
38mm indicated in green and above 38mm indicated in red and
this scale can be used to gauge the variation in length.
. Note! If you are not sure whether the conveyor chain is to be
shortened or not, please contact the supplier of the Spiral
Elevator.
Page 44 of 68
5478EN-3
Technical maintenance
Nominal 267 mm, Maximum 271 mm
Procedure to check chain stretch
• Make sure that the main switch has been switched off, and safely
isolated.
• At a position on the idler or drive end of the Spiral Elevator , stretch
at least 8 conveyor chain plate links apart.
• Measure the distance between the start of plate 1 and the st art of
slat 8 (i.e. the pitch across 7 conveyor chain plates - see pi cture).
For a new chain this distance is 267 mm [10,5"].
• The maximum allowed chain stretch is 1.5%.
• Therefore the metal chain must be replaced when the measured
distance is more than 271 mm [10,67"].
• Refer to section 8 for spare part numbers and contact FlexLink to
procure the necessary parts.
Created by EBCCW 00:06
Figure 11 Tape measure on conveyor chain
. Note! If mor e than 1.5% of the original number of conveyor chain
plate links have been removed to correct chain tension, then this
indicates that the overall chain is in need of replacement..
5478EN-3
Page 45 of 68
Technical maintenance
6.1.3 Checking guide rail
Products that are transported over the Spiral Elevator can make contact
with the guide rail. A stoppage may damage the guide rail. This may later
result in products getting stuck at the damaged place and therefore it is
important that the guide rail is regularly checked for irregularities and is
adjusted or repaired if necessary.
6.1.4 Checking for products sliding
One of the conditions that apply to the S piral Elevator is that products being
transported should not slide.
Conveyor plates have high friction material to avoid this.
Therefore it should be checked regularly whether sliding does or d oes not
occur.
Any observed sliding may have different causes, which can include the
following:
• Worn high friction conveyor which will need to be replaced with
new.
• Produ cts are tran sp or te d that ar e not de scr ib ed in the technical
specification. If this is the case the end user is expected to contact
the supplier of the Spiral Elevator.
• Foreign matter is on the friction conveyor or on the product. This
foreign matter must be removed.
. Note! If the sliding cannot be remedied, please contact the
supplier of the Spiral Elevator.

6.2 Maintenance procedures
It's strongly recommended to perform maintenance activities according to
the methods described. During maintenance proper and safe tools must be
used. Before disassembling any part please r efer to the assembly sectio n
in this manual.
6.2.1 To move the conveyor chain
Follow the below procedure to move the conveyor chain within the Spiral
Elevator:
1 Ensure that the Spiral Elevator is free of products
2 Make sure that the ma in switch has been switched of f, and safely
isolated.
3 Release the brake if present on the gear motor so the chain can
move freely.
4 Depending upon the ratio of the gear motor it may be necessary
to remove the gear motor.
5 Check the conveyor chain moves in the Spiral Elevator smooth ly.
. Note! If the rotation feels very heavy it's possible that the
conveyor chain is jamming somewhere. Check the conveyor
chain and remove any possible obstruction. Make sure the brake
is released.
. Danger: Make sure that the main switch has been switched off,
and safely isolated, in order that there is no possibility that the
spiral elevator can be started unexpectedly.

6.2.2 Replacing conveyor plates(slats)
This paragraph explains how to replace a broken or missing conveyor plate
(slat).
. Note! If a conveyor plate is incorrectly mounted damage to the
Spiral Elevator and the products transported on it may result.
. Danger: Make sure that the main switch has been switched off,
and safely isolated.
Follow the below procedure to replace a conveyor plate (slat):
• The slat can be replaced best at the lower end of the
Spiral Elevator.
• The slat is clicked onto a connection link with two lugs underneath
Figure 12 Removing a slat
• New slats can now be placed on the metal chain. Make sure that
and can be removed from the chain by spreading these lugs. Pull
back on both tips of the slat while keeping your thumbs pressed
on the centre of the slat. The slat lugs will now be spread so that
it can be pulled from the chain see Fig. 10. Repeat this procedure
if more than one slat needs to be removed.
the slat is always placed on the connecting links of the chain and
that the bearing on the slat is placed on the column side of the
track. Pull back on both tips of the slat while keeping your thumbs
pressed on the centre of the slat. The slat lugs will now be spread
so the slat can be placed on the chain (see Fig. 11).
Page 48 of 68
5478EN-3
Technical maintenance
• Apply force on the middle of the slat so that it clicks onto the chain.
You can possibly use a rubber mallet for this. Repeat this
procedure if more than one slat needs to be placed.
Figure 13 Placing a slat
• After maintenance on the conveyor chain test run the machine at
10% of the speed and check if the conveyor chain runs correctly.
. Note! Make sure that the slat is always pla ced on the connecting
links of the chain and that the bearing on the slat is placed on the
column side of the track.
. Note! Each 5 metre of chain is connected by two connecting
links. T o locate these lin ks the slats above them ar e marked with
red dots. Make sure that the correct slats are placed back onto
the chain, possibly marking them.
. Note! The flaps on the underside of the conveyor chain (slats)
are suited for one time use only. Disassembly of the conveyor
chain from the metal chain can cause damage to the flaps and
therefore it is not recommended to re-use conveyor chain links
(slats).
. Note! If a conveyor plate is replaced because a plate is missing,
the chain tension should also be checked.
. Note! If the Spiral Elevator has been provided with bottom
plating, one should check for remainders of conveyor plates. If
these are found, the bottom plating is to be removed in order to
remove these parts.

Technical maintenance
6.2.3 Shorten chain
If the conveyor chain stretch exceeds the limit (see Section 6.1.2 on page
44) the chain must be shortened.
Shortening the chain can best be done at the lower end. FlexLink delivers
a chain tensioner with the machine to assist in this procedure.
Procedure to shorten the chain:
• Every 5 m [16' 5"] the metal chain is connected with 2 connecting
links. The slats located above these links are marked with two r ed
dots. The chain can easily be shortened by removing one of these
two connecting links.
• Create access to the metal chain by removing the conveyor slats
with the red dot plus several conveyor slats either side. The slats
are removed when in the position at the end of the lower end unit.
The procedure for slat removal is detailed in section 6.2.2. The
conveyor chain will need to be moved around to access the slats
and the procedure for this is detailed in section 6.2.1
• First remove the security locks from both connecting links. Once
these have been removed the gold coloured plates and the
connecting link can be removed.
• Now place the chain tensioner if available at both loose ends of
the chain and turn it until both ends meet see Fig. 13.
• Place back one connecting link (including the security lock) and
the chain is then shortened. Fig. 14 shows what parts are taken
out of the belt.
• Return the chain back to the service location and place the new
slats back on the chain. Make sure you place a marked slat over
the connecting link.
• If the metal chain is still too long, repeat this procedure at another
location which still has two connecting links. At least one
connecting link must remain at each relevant location.

6.2.4 Align sprocket wheel
If the conveyor chain does not run smoothly or is noisy, one of the sprocket
wheels at the conveyor ends may not be aligned correctly . This may cause
extra wear of chain and sprocket wheel.
Tools
Procedure to align sprocket wheel at lower or upper end
• Move the conveyor plate with the coloured dot to the lower or
upper end. Remove several of the conveyor plates (slats), so that
when the link is removed from the chain the sprocket wheel is
released.
• The sprocket wheel has been locked to the shaft with an Allen
screw. By loosening this, the wheel can be moved to the lef t or to
the right.
• When the wheel has been aligned correctly, the chain can be
connected again by means of the locking link and subs eq u ently
the conveyor plates can be replaced again. Make sure that a
conveyor plate with a coloured dot is pu t on to the correct position
of the locking link.

6.2.5 Replace sprocket wheel, upper end
Find the conveyor plate with a coloured dot marked on it and move this
conveyor plate to the upper end of the Spiral Elevator. Under this conveyor
plate there is a locking link that can easily be removed.
Tools
. Danger: Make sure that the main switch has been switched off,
and safely isolated.
Procedure
• Remove the conveyor plate with the coloured dot. Under this
conveyor plate there is a locking link and the metal chain can be
separated here. The sprocket wheel is now released from the
chain.
• The gear motor should be dismounted from the shaft. This is done
by removing the bolt mounted in the hollow shaft of the gear motor
and after this the bolt that is connecting the torque arm with the
Spiral Elevator should be loosened. The gear motor can then be
removed.

6.4 Maintenance schedule Spiral Elevator
The FlexLink Spiral Elevator generally requires relatively little
maintenance.
The list below details the general maintenance operations which must be
carried out at the normal time intervals for those maintenance operations.
The maintenance intervals are for a Spiral Elevator operating in normal
conditions with single shift working (8 hours per day) and in a normal
environment.
For more working hours or for an environment which has more dirt or
abrasive particles around or on the Spiral Elevator, the end user must
decide upon the appropriate maintenance intervals t aking in to account all
of the conditions.
To achieve go od wor k in g lif e fro m the Spiral Elevator the various
maintenance items must be done correctly and at the correct time intervals.
Only replacement parts detailed within the recommended spare parts
listing detailed in section 8 should be used. The use of other parts which
are not detailed within the spare parts listing will invalidate the warranty.
For any warranty issues for the Spiral Elevator, all of the maintenance
operations and times must be fully documented and kept in a suitable
maintenance log or the warranty will be void.

No. Execution Interval Remark
1. Clean conveyor Monthly Regular cleaning depends on
product and environment
2. Check the conveyor chain for
broken or missing conveyor
plates, replace if necessary
Daily It is the task of the operator to
check this daily (see user’s
manual)
3. Check the chain tension Monthly Remove a link if the chain is 38.5
mm too long. If more than two
links at the same time are to be
removed, contact the supplier.
4. Check the sprocket wheel
and alignment. Replace or
align if necessary
Monthly Faulty alignment of the sprocket
may cause permanent wear or
make the chain derail and can so
cause serious stoppages.
5. Check the guide rails for
dents, damages and
connection
Monthly Replace guide pieces if they
damage the products to be
transported. If the cause is bad
guide rail, contact the supplier.
6. Clean inside below ends Monthly Accessible dirt will accumulate at
the bottom side.
7. Check the drive for oil
leakage and undue noise
Monthly Repair or replace if necessary.

8. Check whether the Motor is
fastened well to the Spiral
Elevator. Tighten the bolts if
necessary
9. Check the oil level in the
Motor, fill up if necessary
10. Change the oil in the Gear
motor
. Note! Ma ke sure that the main switch has been switched off, and

Put out of commission
7 Put out of commission
Decommissioning should be undertaken in a safe and controlled manner.
This section details the items which must be done for this
decommissioning.
7.1 Disconnect the power sources
The main power isolator must be turned off and 'locked off' or power
permanently removed from the isolator. If the isolator is mounted on the
Spiral Elevator the po wer supply must be permanently removed from the
isolator.
This is to ensure that there can be no electrical supply to the gear motor
connections either before or after the gear motor is removed.
. Danger: First switch off the main switch before the power source
may be disconnected.
7.2 Disassemble
While dismounting the machine, the regulations for waste processing
applicable for the country and local authorities at the time of the dismantling
are to be complied with.
The machine only contains commonly known materials.
At the time of assembly and delivery of the Spiral Elevator there were
processing possibilities for these materials and no particular risks were
known for persons involved in the dismantling process.
The disassembly of the Spiral Elevator generally requires few operations.
Depending upon the height of the Spiral Elevator it may be required to lay
the Spiral Elevator horizontal. If this is necessary the procedure for this is
generally the reverse of the procedure used to stand up the elevator
detailed in section 4.
. Note! At the time of assembling the Spiral Elevator there were
processing possibilities for the various materials within the unit
and no particular risks were known for persons involved in the
dismantling process.

7.3 Transport
While transporting the Spiral Elevator a number of safety measures are to
be taken.
Use the same tools and equipment as indicated in section 4 for th e Unload
of the Spiral Elevator.
A suitable Method S tatement and Risk Assessment for the dismantling and
transportation should be done by the relevant responsible person. This
Method Statement should be followed throughout the decommissioning
process.
. Note! A transport fra me / base should be used which is similar to
the unit used for the initial delivery of the Spiral
. Note! Transport of the Spiral Elevator in the vertical or horizontal
mode depends upon the access route, vehicle height and general
height of the Spiral Elevator.
As a guide, all Spiral Elevators with a total height above 2.4
metres should be transported in the horizon tal mode.

7.4 Disposal
If the Spiral Elevator is to be disposed of, then all current regulations for the
country and local authorities must be adhered to.
The main materials within the spiral elevator can vary depending upon the
design of the S piral Elevator and any accessories attached to the
Spiral Elevator (such as guide rail p arts). The following lists the general
materials within the Spiral Elevator but is not a total list:
• Steel (various grades)
• Stainless steel
• Plastic
• Hardened steel (e.g. bearings and transmission (metal) chain)
•Aluminium
• Polyamide
• Polyethylene
• Oil / grease in bearings, transmission (metal) chain and gear
motor
• Materials within the gear motor
7.5 Reuse
If the Spiral Elevator is to be re-used for another application, then full details
must be checked to establish whether the S piral Elevator is suitable for this
new application.
Clarification for the new application should be sought from the original
Spiral Elevator supplier or FlexLink (there may be a charge for this service).
A full Risk Assessment will need to be completed for the use in the new
application before the Spiral Elevator can be put in to service.
. Note! Putting the Spiral Elevator out of commission or in to a new
use must only be carried out by technically qualified per so nn e l.
