5Function of components
5.1General
LUKAS rope-lift cylinders are manufactured from a high-alloy light metal.
They are designed for an operating pressure of 530 bar.
5
5.2Connecting pieces
In addition to the quick-connect couplings, these cylinder models are fitted with two connecting
blocks with a safety valve to prevent damage to the cylinder under external load. If the specified
maximum pressure is exceed, the safety valves automatically open and oil (protected) is squirted
out.
5.3Hoses between the control table and cylinders
Connection is normally made with 10 m hose pairs red/blue (order no. 84072/1765). All hoses are
fitted with quick-connect couplings and colour coded to prevent them being connected incorrectly:
-Connection to A (= “extend”)red
-Connection to R (= “retract”)blue
5.4Quick-connect couplings
5.4.1 Hose pair compliant with 84072/1765
The hose connectors of this hose pair are fitted with a “quick-stop function” as standard that, for
instance, blocks oil backflow out of the cylinder and prevents the load from lowering if a hose breaks.
The quick stop may be triggered unintentionally when a very heavy load is lowered or the switch
control valve is switched to “Senken” (lowering) too quickly. It will then no longer be possible to
retract the cylinder. If this happens, switch the switch control valve to “Heben” (lifting) until the
cylinder starts to extend. Carefully start the lowering procedure again.
5.4.2 Connection of quick-connect couplings
- Remove dust protection covers.
- Unlock connect socket with adjusting ring by turning it.
- Retract sleeve and connect plug and socket while holding the sleeve in this position.
- Release sleeve and lock adjusting ring: showglass is “RED”.
The connection has now been made and secured.
Note regarding the modified release mechanism as of June 2004
Whenever a connection is made, note the basic functions of the quick-connect couplings
described below:
X
Prior to making the connection, pull back and hold the plug locking sleeve in position (position X).
Fit the socket and plug together and release the locking sleeve. Then turn the locking sleeve to
position Y.
The connection has now been made and locked. Disconnection is made in the reverse order.
It is only possible to connect devices when the hoses are depressurised.
The provided dust protection caps are used to protect against dust.
6
Y
Important!
Some quick couplers have special functions and therefore must not be unscrewed from the hoses
and/or interchanged.
To avoid dirt from entering when the couplings are disconnected, fit dust protection caps on the plug
and socket or, if the couplings are connected, fit the dust protection caps together.
6Initial commissioning
The cylinders must be vented prior to being used for the first time.
-Extend the pistons approximately halfway when they are free from any load.
-Turn the cylinders upside down; the cylinder’s highest point must be under the motor pump
connections.
-Extend the pistons two or three times by using the appropriate switch control valve so that
air can escape from the cylinders and hoses.
7Installation
7.1Safety notes
7.1.1 Prior to installing the cylinder, the load to be lifted must be secured against slipping as
prescribed in the respective applicable guidelines. Always observe the load while it is being
moved by means of the cylinder!
It is forbidden for persons to be under suspended loads. If this is unavoidable in exceptional
situations, then these loads must be adequately mechanically secured so that they cannot shift
in any direction.
7.1.2 General information for cylinder installation / operation
-The ground must be non-slip and level, (warning: hydraulic oils may produce a lubricating
film on the floor.)
-The ground must be a continuous surface (no gratings, gravel etc.)
-Never place cylinders on a yielding support
-Never use cylinders without a piston guard plate in order to prevent piston damage; and
always use a LUKAS radius plate to ensure that force is transmitted safely (refer to
Accessories, Chapter 9).
-Make sure there is centred load initiation on the pistons. If necessary, look for a better
load application point.
7.1.3 Note for cylinder retraction
The load may only be lowered when the pump is running, otherwise a vacuum would be caused
when the load retracts and air would then enter into the hydraulic system.
8Hydraulic connection and operation
8.1General
Only connect the cylinders after installation has been carried out correctly in accordance with
Chapter 7. Switch off the motor pump before connecting hydraulic hoses.
8.1.1 Connection of the rope-lift cylinder
As described in Section 5.3, connect the blues hose first, then the red hose of the hose pair.
7
8.2Cylinder operation
This must be carried out in accordance with the operating instructions of the motor pump used.
8.3Uprighting of rolling stock
With the uprighting system, overturned rolling stock can be turned back to its normal position so
that it may be rerailed.
The lifting belt (4) is fastened to the vehicle framed by means of a holding rope (5) and shackle (6).
The plastic rope is now thrown over the vehicle, and the lifting belt is pulled tight and fastened to
the frame or another superstructural part.
The rope-lift cylinder (1) or tilting jack (3) is used to raise the vehicle at the lifting belt crossbars.
When the cylinder is completely extended, a second rope-lift cylinder or tilting jack is placed in
position for further uprighting.
Each extension cycle must be secured mechanically (beam support).
9Accessories
9.1Radius plates (2)
Radius plates are provided to:
-Increase the base area of the cylinders,
-Increase static stability,
-Level out unevenness of the ground.

10Dismantling of components
Dismantle the components in the reverse order of the installation sequence. Before final
dismantling of equipment, it must be ensured that:
——> The load is in a stable, immovable position<——
——> The hydraulic power pack drive motor must be shut down<——
——> All hoses must be depressurised, by:<——
-Briefly moving the switch control valves to "SENKEN" (lowering) (pressure discharge from
the hoses) and back to the centre position.
-Disconnect the DEPRESSURISED hoses in this order:
——> Hose, piston sidered
——> Hose, rod sideblue
11Maintenance
11.1 Mechanical inspection
Components must be checked to establish that they operate perfectly after each usage
(clean beforehand if dirty):
-Each piston must be checked for smooth retraction (cylinder/ piston O.K.?).
-Check whether all hydraulic screwed connections on cylinders and hoses are still tight; tighten
them if necessary.
-Check whether mechanical damage is evident on the mechanical parts and hoses of cylinders.
-Check on all signs: whether warnings, operation and control symbols and other markings
(colour codings) are present and legible.
-Check whether all safety equipment (protective guards etc.) is present and in perfect condition.
-Check whether the accessories (radius plates, header plates, etc.) are in perfect condition.
9
11.2 Hydraulic system leakage
-Check equipment for oil loss and replace any defective seals.
Important:
Carry out the following procedures over an oilpan; dispose of used oil in accordance with
regulations.
11.3 Cylinder components
Remove any oil remaining in the piston chamber and piston ring zone by fully unscrewing the two
quick-connect couplings from the connecting blocks of all lifting cylinders and carefully draining the
oil.
Flush and fill up with new hydraulic oil. Screw in the couplings tightly and tighten to a torque of
MA=45 Nm Vent cylinders in accordance with Chapter 6.
Note:
Please note that the filled oil must be fully drained and replaced by another type if the operating
conditions (ambient temperatures) change significantly. Also refer to the chapter below.
11.4 Oil recommendation
Oil for LUKAS hydraulic devices: mineral oil in accordance with DIN 51524 and others
Recommended range of viscosity: 10 ... 200 (mm2/s).
