2.3 Initial operation

Inspection before initial operation

Each hoist / trolley must be inspected prior to initial operation
by a competent person and any failures be removed. The
inspection is visual and functional and shall establish that
the hoist is safe and has not been damaged by incorrect
transport or storage. Inspections should be made by a
representative of the manufacturer or the supplier although
the company can assign its own suitably trained personnel.
Inspections are instigated by the user.

Inspection before starting work

Before starting work inspect the hoist / trolley, chains and all
load bearing components every time for visual defects.
Furthermore test the brake and make sure that the load and
hoist / trolley are correctly attached by carrying out a short
work cycle of lifting and lowering resp. travelling in both
directions. Selection and calculation of the proper suspension
point and beam construction are the responsibility of the user.

Inspection of load chain

Inspect the chain for sufficient lubrication any visually check
for external defects, deformations, superficial cracks, wear
or signs of corrosion.

Inspection of chain end stop

The chain end stop must be connected to the free (idle) chain
strand (see Fig. 1 - chain end stop).

Inspection of chain reeving

All units with two or more chain strands should be inspected
prior to initial operation for twisted or kinked chains. The
chains of 2-strand hoists may be twisted if the bottom block
was rolled over (Fig. 9).

Inspection of suspension and load hooks

Inspect suspension and load hooks for deformations,
damage, cracks, wear or signs of corrosion.

Attaching the load

The load must always be seated in the saddle of the hook.
Never attach the load to the tip of the load hook. This also
applies to the suspension hook (Fig. 10).

Fig. 9

Fig. 10

Inspect the traverse (for trolleys)

Inspect the traverse for correct assembly and visually check
for external defects, deformations, superficial cracks, wear
or signs of corrosion. Especially make sure that the roll pins
are properly fitted to the centre traverse (Fig. 12).

Check adjustment of trolley width

On chain hoists without suspension hook (CPE-VTP/G/E)
check that the clearance between the trolley wheel flange
and the beam outer edge is equal on both sides and within
the tolerances given (see page 6, 2. - 3.). Enlarging the
clearances, e.g. to enable the trolley to negotiate tighter
curves, is forbidden.

Assembly of the trolley (see Fig. 12)

1.) Unscrew the locking nuts (item 9) and hex. nuts (item 2)
from the crossbars (item 1) and remove both side plates
(item 6) from the trolley.

2.) Measure the flange width of the beam (see Fig. 1 1 -
measurement "b").

3.) Adjust measurement "B" between the shoulders of the
round nuts (item 5) on the threaded crossbars (item 1).
Ensure that the 4 bores in the round nuts face towards the
outside. Adjust the measurement "B" to equal measure-
ment "b" plus 4 mm. Measurement "A" must be 2 mm on
either side and the suspension traverse (item 4) must be
centred between the round nuts.

4.) Replace one side plate (item 6):
Replace one side plate ensuring that the roll pins (item 8)

engage into one of the bores in the round nuts. To achieve
this it may be necessary to rotate the round nuts slightly .

5.) Replace the washers (item 3) and tighten the hex. nuts
(item 2). Screw on the locknuts (item 9) fingertight and
tighten a further 1/4 to 1/2 turn.
Attention: The locknuts must always be fitted.

6.) Loosely replace the second side plate (item 6) on the
crossbars (item 1). The washers (item 3), hex. nuts (item2)
and locknuts (item 9) can be fitted loosely .

7.) Raise the complete pre-assembled trolley to the carrying
beam.

3.4 Electrical connection
Attention

Work at electrical installations may be carried out by
electrical experts only. The local regulations have to be
strictly observed, in Germany DIN 7100 / VDE 0100 and
DIN 57113 / VDE 0113.

Preparation

• Before beginning work on electrical components the
mains current switch must be switched OFF and secured
against unintentionally being switched back on.

• Before connecting the chain hoist ensure that the
electrical data on the nameplate match the local supply
specifications.

• The mains supply cable must be an insulated cable with
4 flexible leads. The ground (earth) lead must be longer
than the live leads. For wire cross-section and fusing see
table on page 7.

• The length of the pendant control cable is determined by
working conditions. Attach the tension relief wire in a manner
that the pendant control cable hangs load-free.

• Wiring and terminal connecting diagrams are included
with the hoist.

Mains supply connection

1.) The mains supply cable must be connected to the
electric chain hoist before it is connected to the mains
supply.

2.) On chain hoists with an electric trolley (CPE-VTE) the
three phases of the mains supply are to be connected to

the terminal strip within the terminal box on the trolley. The
ground/earth wire is to be connected to the special ground/
earth connection within the terminal box of the chain hoist.

8.) Engage the second side plate (item 6) ensuring that the
roll pins (item 8) engage into one of the bores in the round
nuts (item 5). To achieve this it may be necessary to rotate
the round nuts slightly .

9.) Tighten the hex. nuts (item 2) on the second side plate.
Tighten the locknuts (item 9) fingertight and then a further
1/4 to 1/2 turn.
Attention: The locknuts must always be fitted.

10.) By traversing the trolley check the following:

• that a clearance of 2 mm is maintained on each side
between the trolley wheel flanges and the beam outer edge.

• that the suspension traverse is centred below the beam.

• that all 4 locknuts (item 9) are fitted.

11.) Model CPE-VTG only:
To fit the hand chain position the slot on the outer edge of
the hand chain wheel below the chain guide. Place any
one link of the endless hand chain vertically into the slot
and turn the hand chain wheel until the link has passed
the chain guides on both sides.
Attention: Do not twist the hand chain when fitting.
Geared trolleys are moved by pulling the hand chain.

3.) On chain hoists without electric trolley the mains supply
and the ground/earth wire are to be connected to the
terminal strip within the terminal box of the chain hoist.

4.) After removing the terminal box cover, connect the wiring
as shown on the wiring diagram label inside the terminal
box cover.

Attention: On hoists with direct control the ground/earth
wire should always be connected according to the wiring
diagram. Should the mains supply source not provide a
ground (earth) connection please consult the manufacturer.

5.) After replacing the terminal box cover, connect the other
end of the supply cable to the mains supply .

6.) Check the motor's direction of rotation.
The wiring diagram included has been drawn for a normal,

clockwise rotating installation.Should the user's mains
supply not fulfil these requirements, e.g. the hoist lowers
when lift is selected (or vice versa) switch the unit OFF
immediately and exchange two of the three phase
connections in the mains connection.

Attention:
Under no circumstances may the wiring in the pendant

control be tampered with.

4. FUNCTIONAL CHECK AFTER ASSEMBLY

Prior to operating the hoist, grease the trolley pinions (manual
geared and electric trolleys) and lubricate the load chain when
it is not under load (see page 8).
Before the hoist is put into regular service, following
additional inspections must be made:

• Are all screwed connections on hoist and trolley tight
and are all locking devices in place and secure?

• Are the end stops on the trolley runway in place and
secure?

• Is the chain drive correctly reeved?

• Is the chain end stop correctly fitted to the loose end of
the load chain?

• All units equipped with two or more chain strands
should be inspected before initial operation for twisted or
kinked chains. The chains of 2-strand hoists may be twisted
if the bottom block is rolled over.

• Perform an operation cycle without load. The chain
should move in a steady , smooth way. Check the function
of the overload device by raising the bottom block against
the hoist body (max. 5 sec.).

• Check the brake function when lifting and lowering. The
braking distance must not be more than 50 mm.

• Traverse the trolley (if available) the complete length of
the trolley runway ensuring that the 2 - 4 mm lateral
clearance between the trolley wheel flange and the beam
outer edge is maintained at all times. Check that beam
end stops are positioned correctly and secure.

5. OPERATION

In addition to the recommendation in section 1, following
rules must be strictly maintained to ensure the safe
operation of the hoist:

Users are to be specifically nominated by the company and
must be familiar with all relevant safety regulations.

Traversing the trolley

Plain trolleys: Pull on the load chain of the hoist.
Attention: Never pull on the pendant control cable.
Geared trolleys: By operating the trolley hand chain.
Electric trolleys: By operating the 4- resp. 3-button.
For trolleys with two speeds: The first stage of button
depression activates the slow speed, further depression
activates the fast speed. Use the slow speed for short
periods only.
Consider the braking distance of the trolley. Do not use the
beam end stops as operational limit devices

Attaching the load

Attach the load to the hoist using only approved and certified
slings or lashing devices. Never use the load chain as
sling chain. The load must always be seated in the saddle
of the hook. Never attach the load to the tip of the hook.
Never remove the safety latch from suspension or load
hooks.

Lifting / lowering the load

The load is lifted by depressing the 5-button, it is lowered
by depressing the 6-button. For hoists with two speeds:
The first stage of button depression activates the slow
speed, further depression activates the faster speed. Use
the slow speed for short periods only. Do not use the chain
end stop as operational limit device.

Emergency stop

All movement can be immediately halted by depressing
the red, mushroom shaped button on the pendant control.
Attention: Operating the red emergency button does NOT
automatically disconnect the mains supply to hoist or trolley.
To release the emergency stop, rotate the button in an anti-
clockwise direction.

6. SERVICE

• Service and inspections may only be carried out by a
competent person.

• The inspection must determine that all safety devices
are present and fully operational and covers the condition
of the hoist, lifting gear , accessories and supporting con-
structions.

• The service intervals and inspections noted are for
normal working conditions. Adverse working conditions,
e.g. heat or chemical environments, can dictate shorter
periods.

•The Yale electric chain hoists conform to FEM group 1Am
resp. 1Bm in accordance with FEM 9.511. This results in a
theoretical service lifetime of 800 resp. 400 operating
hours under full load. This is equivalent to 10 years under
normal operating conditions. After this period the hoist
requires a general overhaul. Further information is con-
tained in VBG 9 resp. FEM 9.755.

6.1 Daily checks

1.) Visually check the pendant control switch and cable for

damage.

2.) Check that the brake funtions correctly.

3.) Check that the overload safety device functions correctly.

4.) Electric chain hoists with trolley:

- Check that the trolley runway is free from obstructions

- Check that the end stops on the trolley runway are
fitted and secure.

6.2 Regular inspections, service, testing

According to national and international safety regulations
hoisting equipment must be inspected at least annually by
a competent person. Adverse working conditions, e.g. heat
or chemical environments, can dictate shorter periods.
The commissioning and inspection details can be noted
on the test certificate delivered with the hoist or on page 30
of this manual.
Repairs may only be carried out by specialist workshops
that use original Yale spare parts.

Attention: Tests must - as far as possible - be carried out
in an unloaded condition and the hoist / trolley
currentless.

6.3 LOAD CHAIN

The Yale load chain is grade 80 chain with the dimensions
11 x 31 mm. The CPE electric hoists are specially designed
to use this type of chain. For this reason only chains that
have been approved by the manufacturer may be used in
these hoists.

Lubricating the load chain

The load chain is to be lubricated before initial operation
and every 3 months but the latest after 200 operating hours.
Adverse working conditions, e.g. excessive dust or con-
tinued heavy duty can dictate shorter periods between
lubrication.

• Before the chain is lubricated it must be cleaned. Flame
cleaning is forbidden. Use only cleansing methods and
agents that do not corrode the chain material. Avoid
cleansing methods that can lead to hydrogen brittleness,
e.g. spraying or dipping chain in caustic solvents. Also avoid
surface treatments that can hide cracks and flaws or other
surface damage.

• The chain must be lubricated in a no-load condition so
that lubricant can enter between the links, e.g. by dipping in
oil.

• Motor oil of the voscosity 100, e.g. Shell Tonna T68 can
be used to lubricate the chain. For very dusty applications
use a dry lubricant.

Inspecting the load chain for wear

Load chains must be inspected every 3 months or the latest
after 200 operating hours (see VBG 8 § 27 or local regu-
lations).

Visually inspect the chain over its full length for defor-
mation, cracks, flaws, elongation, wear or corrosive pitting.

Link chains must be replaced when the nominal thickness
"d" on any part of the chain has been reduced by more than
10% or when the pitch "t" is elongated by more than 2%
or over 11 pitches (11 x t) by 2%. Nominal dimensions and
wear limits are shown in the following table.

Chains that do not fulfil all requirements must be replaced
immediately.

tube in the direction of the chain and tap out the chain bolt
with a drift.
Attention: Do not damage the chain bolt bore.

2. Remove the chain end stop.
Remove the 2 screws. The chain is now free.

3. Fitting the new chain
Cut the second to last link open on the loose end of the
load chain to form a "C". Remove the last link and connect
the new chain. The new chain must be fitted so that the
welds on the standing links face towards the chain guide
and away from the load sheave. Operate the hoist in the
lowering direction to feed the chain through the hoist.

4. Fitting lower block and chain end stop
Slide the end buffers over the loose ends of the load chain
and refit bottom block and chain end stop. The chain end
stop must be fitted so that at least 1 link remains free (see
Fig. 1)

5. Before initial operation lubricate the unloaded chain and
test all hoist functions under no-load condition.

2-strand design

1. Remove the chain anchor bolt
The chain anchor bolt is situated on the underside of the
hoist body. With an Allen key remove the grub screw that
serves as locking device. Tap out the chain anchor bolt
with a drift from the other side.
Attention: Do not damage anchor bolt or bore.

2. Pull the load chain through the bottom block and remove
the chain end stop.

3. Fitting the new chain
Cut the second to last link open on the loose end of the
load chain to form a "C". Remove the last link and connect
the new chain. The new chain must be fitted so that the
welds on the standing links face towards the chain guide
in the housing. Operate the hoist in the lowering direction
to feed the chain through the hoist.

4. Replace chain end stop
Slide the buffer pad over the loose end of the load chain
and refit the chain end stop ensuring that at least 1 link
remains free (see Fig. 1).

5. Fitting the chain anchor bolt
Inspect the chain anchor bolt for flaws, cracks or burrs.
Enter the last link of the other load chain end into the slot in
theunderside of the hoist body . Attention: The chain must
not be twisted. Now enter the chain anchor bolt through the
side bore. Move the last link back and forth while entering
the chain anchor bolt to ensure that it is not trapped and
damaged by the anchor bolt. Secure the anchor bolt with
the grub screw.

6. Assemble the bottom block
Check the idler sheave for damage. Position the load chain
over the idler sheave ensuring that the welds on the standing
links face away. Grease the needle bearings in the bottom
block halves. Place the load hook assy in the slot provided
in one of the bottom block halves and push the complete
unit onto the idler sheave. Ensuring that the buffer pad is
situated correctly in its groove replace the second bottom
block half and secure with the screws.

7. Functional test
All units with two or more chain strands must be inspected
before every operation for twisted or kinked chains. Chains
on 2-strand units may become twisted if the bottom block
is rolled over. If a strand is twisted disconnect it from the
hoist and re-thread it correctly . In some cases it may be
necessary to remove the last link.

8. Before initial operation lubricate the unloaded chain and
test all hoist functions under a no-load condition.

6.4 Load and suspension hooks

Inspect the hooks for deformation, damage, surface cracks,
wear and signs of corrosion as required but at least
annually. Adverse working conditions may dictate shorter
periods. Hooks that do not fulfill all requirements must be
replaced immediately, W elding on hooks to compensate
for wear or damage is not permissible. Hooks must be
replaced when the mouth of the hook has opened more
than 10% (Fig.14) or the nominal value of other dimensions
has decreased by 5% due to wear . Nominal dimensions
and wear limits are shown in the following table.

6.5 Trolleys

In particular check following parts:

• Side plate
For cracks or deformation in particular around the areas of
screwed connections.

• Trolley wheels
Visually check for cracks and wear on trolley wheel flanges.
Grease the transmission.

• Crossbars
In particular around threaded areas for cracks.

• Fasteners
Check nuts, screws and locking devices for tightness.

6.6 Electric chain hoist in general

In particular check following parts:

• Threaded connections in general
Check all nuts, screws and locking devices for tightness.

• Chain container
Ensure the chain container is securely fastened. Check
for cracks or wear.

• Suspension pins
(Connection between hoist and suspension hook resp.
trolley) Check for cracks or wear. Ensure all safety devices
are in place and secure.

6.7Overload protection device

The overload protection device ( slipping clutch) is factory
set to 110% ± 10% of the rated capacity and can be checked
by lifting a suitable load. If the device slips at the rated
capacity load it can be adjusted as follows (see Fig. 19):

• Unscrew the threaded pin (9) which locks the straining
screw (45).

• Increase the moment of friction by turning the straining
screw (45) in clockwise direction.

• Re-check the adjustment with a suitable load.

• Lock the straining screw (45) with the threaded pin (9).

6.8 Gearbox

The gearbox is practically maintenance-free. Service is
therefore reduced to changing the oil.

Oil change

The oil (approx. 0,3 l) is to be changed every 5 years or at
the latest after 400 operating hours.
Disassemble the gear cover (51) by removing the cylinder
screws (52) and unscrew the screw plug (44). Place the
hoist horizontally and turn so that the oil can drain from the
fill hole into a suitable container (approx. 30 minutes).
Replenish the gearbox oil. W e recommend a mineral oil
viscosity class ISO-VG 460, e.g. FINA GIRAN L 460. Finally
re-adjust the overload protection device.
