ELECTRIC WIRE ROPE HOIST
XM SERIES
3.6 MOUNTING DOUBLE RAIL TROLLEY
Lift the trolley hoist with a mobile crane using
the hold points provided and lay it on the pre-
arranged travel rails, after checking the exact
gauge of the strokes.
3.7 BLOCK MOUNTING
To ensure the safe and reliable operation of the hoist,
special care must be given to the fixing of the two rope
ends, observing the following instructions.
For transport reasons, the block is delivered loose,
detached from the ropes. In this case, perform the block
mounting paying attention to the following points:
• the rope should not be twisted, but tight.
To mount the block for rope hoists with 2 or
4 falls, follow the correct sequence of rope
rotations, between the drum output and the
pulley, up to the socket as in figures S2 (2/1),
S4 (4/1) and D2 (4/2) on page 11.
Pass the rope through the pulleys and fix it to
the relevant transverse beam by inserting the
wedge into the compartment of the socket
without twisting the rope.
Check the anti-fall brackets for proper
mounting.
Before inserting the rope in the socket, make
sure the wedge supplied cannot come out
from the lower hole of the socket without the
rope wrapped around it, as shown below.

3. INSTALLATION INSTRUCTIONS
Position the trolley and tighten the plates.
The space between the wheels and the beam
flange must be 3÷4 mm. see Fig. 1 on page 16.
Reassemble the pin pos. 2 and the cotter pin
pos. 1.
After mounting, verify the trolley travels
smoothly and that there are no obstacles, such
as projection on beam flanges, junctions plates,
bolt heads, etc. Provide rubber stoppers at the
ends of the trolley stroke as shown below.
