Wearing parts
The following parts are subject to increased wear and tear:
• the rubber pads of the swivel arms
• the supporting nut of the nut system
• the guiding rollers of the carriages
These and other spare parts of the lifting system are supplied on order.
Replacement of wearing parts
Repair and maintenance works of any kind must only be carried out after the
power supply of the unit has been disconnected. Repairs of the electrical
system must only be carried out by a qualified electrician in accordance
with the applicable country-specific regulations or the CE regulations. For
repair work of any kind, the technical service of the manufacturer or the
supplier is available to the operator.
Replacement of the rubber guides of the chain
Remove the cover plate of the base frame. Loosen the connection of the
rubber guide to be replaced, replace the guide and properly fix the new
guide. Assemble the cover plate to the base frame again.
Replacement of the nut system
Remove the cover plates of the lifting posts. Move the carriage to the lower
limit of travel. Loosen the fixing screws of the upper bearing.
Remove the cable of the switch system from its guiding elements. Use a
crowbar to lift the spindle at the nut system and remove the suspension
components.
Turn the spindle to screw the nut system towards the end of the spindle. Lift
the spindle by about 150 mm and remove the feather key at the end of the
spindle; screw the nut system off the spindle and put a new one into the
carriage. The distance between supporting nut and safety nut is 24 mm (min.)
to 30 mm (max.).
Assembly is done in reverse order of disassembly.
After the control cable has been assembled anew, the function of the cable
switch system must be checked.
Do not reassemble a defective control cable. It is, however, recommended
not to reassemble even fully undamaged cables, as our experience revealed
that the usually extremely long service life of the control cable is in most cases
considerably shortened by reassembling.
Tension the V-belts properly. Reassemble the protection covers. Then, the
directions for installation must be observed.
