IV. INSTALLATION

1. UNPACKING INFORMATION

After removing the trolley from the shipping carton/crate, carefully inspect the external
condition of the cord, electric housing, gear reducer, motor for damage that may have
occurred during shipment and handling. Check to make sure all parts are furnished. i.e. trolley
side frame with electric housing, side frame with reducing gear motor, position tube, spacer
washer, stay-bolts, nuts and load plate for hoist top hook. Also, before attempting to install
the trolley, make sure that the power supply indicated on the labels attached to the motor
housing is the same as the power supply on which the unit is to operate.
Generally, the hoist and trolley are packed separately. Except when the order indicates the
requirement of 4-way control for the hoist with trolley, then the hoist will be packed with
trolley together in one wooden crate.
For all trolley suspended hoist rail stops must be installed at each end of
the rail. Failure to install rail stops will allow the hoist and trolley to fall off
the end of the rail and thus cause an accident that may result in injury
and/or property damage. The stops must be positioned as to not exert
impact force on the hoist frame or trolley wheels. They must contact the
ends of the trolley side frames.

2. TROLLEY TO BEAM

It is recommended that the trolley be mounted on the beam prior to attaching the hoist to
the trolley. Before attempting to mount the trolley on the beam, measure the actual width of
the beam flange on which the trolley is to operate. Using this measurement determine the
arrangement of spacer washers between the two trolley side frames. First loosely assemble
the side frames, position tubes, spacer washers and nuts on the stay bolts.
The trolley and beam should be inspected periodically to assure their
continued operations. Operating a malfunctioning trolley and/or operation
the trolley on a beam with an excessively worn flange may allow the trolley
to fall from the beam causing an accident that may result in injury and/or
property damage.
