TROLLEY INSTALLATION
1. Be sure that your beam and its structure can support the weight of the hoist and
its rated load.
2. The trolley comes packaged already assembled. To attach the hoist, you will
need to remove the lock pin from the end of the shaft and any external spacers.
Remove the electrical plate and any spacers.
3. To fit the trolley to the beam you will need to calculate the correct number of
spacers on both sides of the coupling so that the center of the coupling is in line
with the web of the beam. Take the measurement of your beam flange.
4. You will need to lay out the trolley to measure the number of spacers you will
need. Connect the 2 trolley plates together by inserting the shaft into the plates.
Take note of the guide rollers on each plate. These guide rollers are where the
internal measurement will be taken. Spread the plates the same distance apart
as the width of the beam’s flange. Now you can measure how many spacers you
will need on the shaft- either side of the coupling. Make sure to leave 1/8-inch
space on both sides of the coupling. (Refer to the diagrams below)
(Flange width – thickness of co ¼ inch = total length of spacers)
All 4 guide rollers must roll along the edge of the beam flange. The ¼-inch space
that was left is to allow the trolley to roll without getting caught while moving.
