3. Proper use
LUKAS-HP cylinders are especially designed for re-railing technology. In the event of derailed rail vehicles, they are used to lift the vehicles so that they can be re-railed, e.g. with an
additional transfer unit. Furthermore, they can be used to lift a rail vehicle in order to push a
towing device underneath it, for example.
HP cylinders in telescopic design offer long hoisting paths with a low retracted overall
height.
The accessories necessary for the particular application, such as base plate, multistage sets
etc., must be used during each deployment.
CAUTION!
Watch out vigilantly for any leaks in order to avoid threats to the environment.
Recommended accessories for HP cylinders:
- Base plate (Item 1)
- Multistage set (Item 2)

5. Functions and performance
5.1 Description
HP cylinders are double-acting hydraulic cylinders. Extension and retraction takes place
hydraulically. The direction of movement is controlled by pressurising the piston rod side or
the cylinder base side. Control of the pressurisation must be effected by an external control
unit (e. g. control panel) and a connected hydraulic unit (the use of a hand pump is possible
in exceptional cases).
Securing against unwanted lowering of the cylinders in the event of a hose breakage is
achieved by means of quick-stop couplings tted to the hose. If there is any doubt as to
which coupling sleeves are tted to your hose, please contact your authorised LUKAS dealer
or LUKAS directly before using the hose.
In addition to the quick-disconnect couplings, the HP cylinders are additionally equipped with
two connection blocks with integrated safety valve. These safety valves protect the cylinder
from damage caused by sudden load increase (e.g. something has additionally fallen onto
the part to be lifted, thus suddenly increasing the weight). If the specied maximum pressure
is exceed, the safety valves automatically open and hydraulic uid (protected) is squirted
out.
HP cylinders in telescopic design offer long hoisting paths with a low retracted overall
height.
9
5.2 Controlling the operating movements
When the valve (A) is pressurised on the cylinder base side, the piston rod is extended. By
pressurising valve (B) on the piston rod side the piston rod retracts again.
B
A
5.3 Hydraulic supply
Only LUKAS motor pumps (or hand pumps in exceptional cases) may be used to drive the
devices.
If the pump unit is of a different make, you must make sure that it complies with LUKAS
specications, otherwise hazards may occur which are not the responsibility of LUKAS.
Ensure in particular that the maximum permissible operating pressure for the connected
LUKAS equipment is not exceeded.
NOTE:
Before you use pumps from a different manufacturer, you must contact LUKAS
or an authorised dealer.
5.4 Hose lines
The pump unit and the HP cylinder are connected by hoses.
10
6. Connecting the equipment
6.1 Hydraulic
On the device side, a quick-disconnect coupling sleeve is provided on the piston rod side of
the valve, and a quick-disconnect coupling nipple on the cylinder base side of the valve; they
are connected to the pump unit via two extension hoses.
All LUKAS pairs of extension hoses are colour coded and are equipped with quick-disconnect
couplings so that they cannot be mixed up when being connected.
WARNING / CAUTION / ATTENTION!
Prior to connecting the devices, ensure that all the components
being used are suitable for the maximum operating pressure
of the pump unit. In the case of doubt you must consult LUKAS
directly!
6.2 Coupling quick-disconnect couplings
The equipment is connected to the hydraulic pump via quick-disconnect-coupling halves
(male and female).
X
Y
Before coupling, remove the dust protection caps and then pull back and hold the locking
sleeve of the female coupling half (position X). Connect the male and female coupling together
and release the locking sleeve. Then turn the locking sleeve to position Y. The connection has
now been made and locked. Disconnection is carried out in the reverse order. Hoses can be
connected only when depressurised. For dust protection, the supplied dust protection caps
must be retted.
CAUTION!
Always connect the return hose rst and then the supply hose!
NOTE:
It is only possible to connect devices when the hoses are depressurised.
For dust protection, the supplied dust protection caps must be retted.
WARNING / CAUTION / ATTENTION!
Some quick-disconnect couplings have special functions and may therefore not
be unscrewed from the hydraulic lines and/or swapped!
11
7. Operation
7.1 Installation
CAUTION / ATTENTION!
Prior to installing the cylinders, the load to be lifted must be secured against
slipping as prescribed in the respective applicable guidelines and regulations.
The following must generally be observed when installing the cylinders:
- Non-slip and even ground, so that the entire base area of the cylinder is lying on the
ground. If there is any doubt as to the load-bearing capacity of the ground, suitable
wooden or metal underplates must be used to increase the contact area.
WRONGRIGHT
ATTENTION!
Hydraulic uids may produce a lubricating lm on the ground!
- The ground must be a continuous surface (no gratings, gravel etc.)
- Never place cylinders on a yielding underplate
CAUTION / ATTENTION!
When using wooden underplates, care must be taken that particularly hard
wood without damage is used, so that the underplate cannot crack. Additional
clamping together of other woods with metal straps is not sufcient!
- Never use cylinders without a piston guard plate, in order to avoid damage to the
piston and achieve safe power introduction
ATTENTION!
Use an additional non-slip underplate between the piston guard plate and the
load to be lifted, as a lubricant lm may be present at the contact point of the
load!
12
- Please ensure that the load is applied centrally to the piston rod.
NOTE:
You may need to look for a more favourable load application point!
Position the cylinder underneath the centre of gravity of the load, such that the load
cannot tip over during lifting and endanger the operating staff or the cylinder itself.
The load should always contact the middle of the piston area. Side loads should be
avoided!
Load
WRONG
It is usually not possible to make the load contact the full area of the cylinder piston. We
also recommend the use of suitable piston guard plates for this reason, as otherwise
there is a risk of damage to the piston rod or the cylinder. A convex piston guard plate
distributes the load evenly over the piston area again.

7.2 Commissioning
WARNING / CAUTION / ATTENTION!
Always keep a sufcient distance away from the hydraulic cylinder when
pressurising it, in particular when commissioning the equipment after
installation!
ATTENTION!
Each time before putting into operation, make sure that the hydraulic
connections to the cylinders are properly made and in full working order.
Incorrectly made connections or defective couplings can lead to a safety valve
responding (e.g. on the coupling nipple in the case of hoses with safety quickdisconnect coupling nipple)!
14
7.2.1 Initial operation
Before commissioning and following repairs, the device must be de-aerated.
- Connect the equipment to the hydraulic pump (see chapter “Connecting the
equipment”).
- Fully extend and retract the device several times without load.
NOTE:
We recommend that during the de-aeration, the attached unit for the hydraulic
supply should stand on a higher level than the cylinder.
The connections on the hydraulic cylinder should face upwards.
7.2.2 Checking the pump unit
See separate operating instructions for the corresponding unit (or hand pump).
NOTE:
Before working on the pump unit or connecting/disconnecting hoses, always
make sure that the pump unit is switched off or disconnected from the supply
in the case of electric pumps, and that the control valves have been set to
depressurised recirculation.
7.3 Hydraulic cylinder control
Movement of the cylinder piston cannot be directly controlled by the cylinder. Extending
and retracting the cylinder must be controlled via a separate control unit or the connected
hydraulic unit.
15
8. Use of accessories
8.1 Base plate
Base plates are provided to:
- Increase the base area of the cylinders,
- Increase static stability,
- Level out minor unevenness of the ground.
Assembly of the base plate:
Place the cylinder onto the base plate in such a way that the coupling connection is positioned in the corresponding recess in the
centring tube. You must then tighten the three xing screws on
the centring tube. This way, the cylinders can be carried together
with the base plate.
8.2 Multistage sets
NOTE:
Multistage sets are specically designed for individual cylinders.
To nd out which multistage set is suitable for your cylinder, please contact your
authorised dealer or LUKAS directly.
Multistage sets consist of:
- Cylinder attachments (Fig. right, item 1),
- Piston attachments (Fig. right, item 2),
- Fork lever (Fig. right, item 3)
Application case for multistage sets:
Multistage sets enable an increase in load lifting
height beyond the stated cylinder stroke. For space
reasons, cylinders with large strokes often cannot be
used due to their large overall height. Multistage sets
make it possible to use cylinders with small overall
height to lift loads very high.
Installation / operation of the multistage sets:

9. Dismantling the device /
deactivation following operation
WARNING / CAUTION / ATTENTION!
Before dismantling the re-railing equipment, please ensure that the moved load
is in a stable and rm position!
9.1 Hydraulic cylinder
After completion of the work, the hydraulic cylinders must be retracted leaving only a few
mm*) projecting. This relieves the hydraulic and mechanical strain on the device.
NOTE:
When hydraulic cylinders are in storage, fluctuations in ambient temperature
can cause the pistons to move slightly. This phenomenon is due to the
difference in the expansion of the hydraulic fluid enclosed on the piston side
and the rod side.
*) 1 mm = 0.04 in.
9.2 Hydraulic unit
Upon completion of work, the unit must be deactivated.
9.3 Hose lines
First of all, decouple the pressure hose then the return hose as described in chapter
“Connecting the equipment”.
Ensure that you replace the dust protection caps onto the mono-coupling halves.
20
10. Maintenance and service
A visual inspection must be carried out after every use, but at least once a year. Every
three years or if there is any doubt regarding the safety or reliability of the equipment, a
functional test must also be performed. (Please also observe the relevant valid national and
international regulations pertaining to service intervals of hydraulic equipment).
ATTENTION!
Clean off any dirt before checking the device!
WARNING / CAUTION / ATTENTION!
In order to carry out maintenance and repair work, tools appropriate for the job
and personal protective equipment are essential.
Inspections to be carried out:
Visual inspection
• Cylinder and piston rod undamaged and not deformed,
• Piston guard plate present and undamaged,
