Check power supply that will be furnished to the hoist and trolley. It must be the same as shown on the hoist and
trolley serial plate.
Check wire rope for damage and spooling on drum. Be sure rope is properly seated in drum grooves and
sheaves. Make sure both of rope ends are tightly secured.
After each rope replacement as well as after repair and reassembling of the electric hoist check the phasing and
the limit switch adjustment for upper and lower position of the loading hook.
While carrying maintenance and repair activities for electric repairs/maintenance, make sure that there is no load
on the hook; the power supply switch is turned off and unauthorized switching on is eliminated.
Check the loading hook for cracks and deformations as well as the good working order of the fuse for self-
release of the load.
Check the bearing screw joints to avoid them eventually self-unwind.
Check the reliable connection of cable protective conductors to the grounding terminals in the electric board as
well as the transformer and the electric.
If hoist has a trolley, check that the crane bridge beam or monorail beam is level, straight, and clean. Check that
trolley stops are installed, or install trolley stops, at the open end or ends of the beam to prevent the trolley from
traveling off the beam. Trolley stops that engage trolley wheels are not recommended. Check that trolley stops
will prevent overhanging parts of the hoist and trolley from interfering with other equipment beyond the ends of
the beam or monorail.
4.2 Installation of Hoist
Fixing the Rope
Depending on the size of the electric hoist and the conditions of packing, the hook-block may be delivered disassembled
from the rope. After installing the hook-block, the rope must be tight and shouldn’t be twisted. Fix the rope ends as in the
following order:
Fixing the rope end to the body (See Figure 4.2.1)
Fix the rope of diameter “d” in the wedge bush 2, so that its bearing section would lie on the vertical side of the wedge 1.
To secure the rope ends from falling out, a clamping element 3 is mounted by nuts at the end of the rope.
The distance between the rope end and the wedge bush 2 shall be at least 3.9 inches the maximum distance is:
9.8 inches for 0.5 and 1 ton hoist capacity
13.8 inches for 2, 3, 4 and 5 ton hoist capacity
17.7 inches for 8 ton hoist capacity
The distance between the clamp 3 and the rope end shall be 1.97 inches.
The main switch (disconnect) supplying power to the crane, monorail, or other piece of
equipment where the hoist is to be installed, shall be de-energized. Lock and tag the main
switch in the de-energized position in accordance with ANSI
Z244.1.
