With the trolley mounted on the beam, attach
the hoist by inserting the suspension lug into the trolley
load bracket and inserting the suspension pin through
the load bracket and suspension lug as shown in Figure
Thread the socket head cap screw and
lockwasher into load bracket and tighten securely.
Now, return to page 4 "Power Supply and
Then with a capacity load on hoist, operate
trolley over the entire length of runway or monorail
system to be sure that the adjustment and operation is
satisfactory. On systems with curves, the edges of the
rail at the curved sections should be kept lightly
lubricated with grease.
Motor Driven Trolley
This trolley is shipped separately and must be
assembled and wired to the hoist by the user. Refer to
the instruction manual packed with the unit.
Enclosed Collectors and Wiring
On low headroom trolley, collectors are to be
installed on each side of trolley. On motor driven
trolley, all collectors are to be installed on one side of
Make sure power supply to conductor system is
Refer to Figure 9 to determine the proper
mounting position for the collector bars and
Attach the brackets by inserting the screws into
tapped holes in the side frames. Tighten screws
Place an insulator on each collector bar.
Position the bars in the brackets and lock with
set screws. Mount collectors on bar to match
Again refer to Figure 9 position the collectors
on. the bars as shown.
Measure the length of power cable needed t
reach the farthest collector. Allow for
connecting the wire to the collector shunt screw
and cut off the cable.
Strip back the insulation as required and cutoff
Green wire if no ground conductor is installed.
Attach wires to collector's shunt screw ( Fig. 8).
Check installation to make sure that the
collectors make proper contact throughout the
entire length of trolley travel.
Energize conductor system. On three phase
units check for proper direction of hook travel by
following instructions on page 5.
ALTERNATE METHODS OF WIRING
A flexible conductor cable can be used to supply
power to a trolley mounted hoist. The length of
conductor should be adequate for the full travel of
trolley. A long conductor will usually require a clamp or
strain relief (available from factory) fitting at the hoist to
prevent kinking where the conductor enters hoist. To
keep the slack conductor awe from the hoist and load, a
messenger wire system, a counterweighted pulley or a
spring loaded cord reel (available from factory) can be
