Installation
4.1. Setting up
• The machines can be used in lift systems with or without a machine room
• The permissible uneveness of the mounting surface is 0.5 mm. The mounting surface must be sufficiently dis -
tortion-resistant and stable to accommodate the forces occurring in the system.
• The rope force can be applied to the lift machine in any direction
• The machine must be mounted on vibration dampers for vibration damping
• No welding work may be performed on the lift machine, nor is it permissible to use the machine as a mass
point for welding work. This might cause irreparable damage to the bearings and magnets.
• If there are more grooves on the traction sheave than the number of ropes used, position the ropes either in
the centre of the traction sheave or towards the motor end.
Danger
Be sure to use calculations to check the base frame or foundation loads before installing the
lift machine.
Warning
Cover the machine and especially the brakes when doing any machining or dust-producing
work in the shaft or machine room.
• The measuring system is only accessible from the rear side. Therefore, leave enough space between the wall
and the rear side of the machine or ensure that the machine can be moved away from the wall.
Securing the machine
• Fasten the machine using 8
M 36
bolts -
strength class 8.8; tightening torque: 2,360 Nm
.
• After completing the adjusting work or after a breakdown, tighten all the fastening bolts of the machine,
using the specified torque .
• Lift machines are generally equipped with rope slip-off guards. After putting the ropes in place, adjust them
so that the distance between the rope and the rope slip-off guard does not exceed 1.5 mm.
• If the lift machine is not installed at the head of the machine room as is usually the case, it may be necessary
to modify the fitting of the rope slip-off guard to fulfill the requirements of EN 81-20 . Optional rope slip-off
guards are available for this purpose.
Danger
Attention should be paid to specifics of the W
G U
-29 lift machines - see section 11. (Lift
machines with split housing design and with UL/CSA approval)
