Securing the hoist car on the mast
A car locking device is located behind a cover panel in the car
wall – intended to be used during transport of the hoist base
unit, or when service work is to be carried out on the mast
under the car. The car locking device can be applied anywhere
on the mast’s rack.
Function
Remove the cover panel.
Push the cog segment in proper location and tighten it fully
against the mast’s rack with the M-16 bolt provided.
AFTER use – reset the cog segment to its outermost position.
The locking device is mechanically interlocked and electrically
supervised in such way that the covering panel cannot be
reinstalled if the cog segment is not fully reset. A cam, rear on
the cover panel closes an electrical contact in the hoist’s safety
circuit when properly reinstalled.
The hoist cannot be started if the cover panel is missing.
IMPORTANT
In conjunction with disassembling the drive unit from car ...
... the motor brakes must be lifted and the drive unit lowered by
gravity so that the car’s own weight and possible load are
transferred from the drive unit’s pull rods – to the car locking
device cog segment and the mast’s rack.
Before resetting the cog lock segment ...
... in conjunction with assembling the drive unit, the electric
motors must be cranked in upwards direction with a ratchet
spanner (approx. 30°) one by one in sequence 1st, 2nd and 3rd,
as noted below.
Repeating the procedure – until the car’s own weight is placed
on the machinery’s pull rods.
During the operation described above the car must be located at
the base landing and the main power switch turned and locked
with a padlock in Off-position to prevent accidental starting in
downwards direction.
The ratchet spanner must NOT be replaced with a fixed wrench
due to the ratchet spanner’s free rotating in opposite direction.
