ELECTRIC WIRE ROPE HOIST
XM SERIES
Remove the cotter pin pos. 1, remove the pin
pos. 2, and open the plate pos. 3 to allow the
wheels to pass on the external edge of the beam
flange.
3. INSTALLATION INSTRUCTIONS
If the rail has one open end, fit the trolley on the
open end of the rail and lock the rail end with
a fixed stopper.
TROLLEY FIG. 83
Before installing the hoist on the beam,
you need to check correct correspondence
between the width of the beam and the
dimension
LT (width of the beam taken by
the manufacturer on the trolley LT = Beam
wing + 3÷4 mm).
To mount the hoist in a closed end rail, widen
the plate on the nut side proceeding as follow:
Nut
Cotter pin
Tie bolt
Trolley plate
Any washers
for external regulation
Remove the cotter pin pos. 2, loosen the nut
pos. 1 until the plates spread enough to allow
the wheels to pass on the external edge of the
beam flange.
Place the trolley in position and restore the proper
wheel base, paying attention to leave 3÷4 mm
between the beam flange shown in Fig. 1 on page 16.
Press the plate against the inner spacers,
tighten the nuts again paying attention that the
slot of the slotted nut pos. 1 is aligned with the
hole of the tie bolt, insert the cotter pin pos. 2
and bend the ends of the cotter pin so that it
cannot come out.
In case of low headroom trolleys, before opening
remove the counterweight, paying attention to
put it again in position before tightening the nuts.
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.
Low headroom trolleys are available with
counterweights made of steel sheets with a
pre-set weight located at the end of the tie
bolts on the side of the travel gearmotor.
Verify the proper balance and grip of the driving
wheels with no trolley load, in order to prevent
slipping.
TROLLEY FIG. 3
Before installing the hoist on the beam,
you need to check correct correspondence
between the width of the beam and the
dimension
LT (width of the beam taken by
the manufacturer on the trolley LT = Beam
wing + 3÷4 mm).
