II. OPERATING AND SAFETY PROCEDURES
The following are operating and safety procedures for safe operation of the Pacific motor driven
trolley. Taking precedence over and specific rules listed here, however is the most importance
rule of all. A few minutes spent reading these rules can make an operator aware of dangerous
practices to avoid and precautions to take for his own safety and others.
1. Immediately after installation, operate trolley with safe working load over the entire length
of runway or monorail system to be sure that all adjustments and operations are
satisfactory.
2. Rail stops must be installed for all trolleys operating on open end beams. These stops must
be positioned such that impact forces are absorbed by trolley side frames only.
3. When preparing to lift a load, be sure that the attachments to the hook are firmly seated in
hook saddle. Avoid off center loading on the point of hook.
4. When lifting, raise the load only enough to clear the floor or support and check to be sure
that the attachments to hook and load are firmly seated. Continue lift only after you are
assured the load is free of all obstructions.
5. When applying a load, it should be directly under the trolley. Avoid off center loading of
any kind.
6. Take up a slack load chain carefully and start lifting load slowly to avoid shock and jerking
of hoist load chain. If there is any evidence of overloading, immediately lower the load and
remove the excess load.
7. Do not allow the load to swing or twist while hoisting.
8. Anticipate the stopping point and allow trolley to coast to smooth stop. Reversing or
plugging to stop trolley causes overheating of motor and swaying of load.
9. Do not load trolley beyond the rated capacity. Overload can cause immediate failure of
load carrying parts of cause damage resulting in future failure at less than rated capacity.
10. Do not use this or any other overhead materials handling equipment for lifting or
transporting people.
11. Stand clear of all loads and avoid moving a load over the heads of other people. Warn
people of your intention to move a load in their area.
12. Do not leave the load suspended in the air unattached.

5
13. Do not wrap the load chain around the load and hook into itself as a choker chain.
Doing this will result in the follow:
(a) Operation of the upper limit switch is bypassed and the load could hit the hoist.
(b) The loss of the swivel effect of the hook which could mean twisted chain and a
jammed lift wheel.
(c) The chain could be damaged at the hook.
14. Permit only qualified personnel to operate the unit.
III. GENERAL INFORMATION
The Pacific motorized trolleys are designed for use with the Pacific Electric Chain Hoists. The
trolleys are available in the following capacities: 0.5-Ton~2-Ton, These trolleys are similar
except for the size of the load carrying members.
The trolleys have rugged steel side plates with anti-drop fins, steel wheel axles, steel suspension
bolts, construction steel load plate seated in middle of two suspension bolts for top hook of
hoist to hook on. The hot forged travelling wheels machine to suit both I-beam and flat beam.
Hardened steel gears are attached to two trackwheels and driven by a hardened steel pinion.
The pinion is driven by planetary gear reducer in high quality grease. A weather proof motor
drive the gear reducer.
The electric housing contains a reversing contactor and a terminal boards. The transformer will
be an option depending on the user's need. The 1-phase motor is always equipped with a
magnetic brake over the end of driven motor. Above the housing bottom, there three holes,
one for cord from hoist, another for control cord from hoist, the third one for trolley motor cord,
it will serve as an option for equipped with the Push-Bottom-Station cord for the trolley. In
addition, there are two option holes on each side of the housing, motor power cord on the right,
and an optional hole for the power cord to trolley on the left. All five holes are equipped with
cable gland for IP-55 protection optionally. Please refer to Illust: 1 on page 9.

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.
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.
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.
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.

7
Due to the variations in beam flange widths, it is suggested that the beam flange width be
measured to determine the exact distribution of spacer washers. The distance between
trackwheel flanges should be 3-5 mm greater than the beam flange width for straight runway
beams, and 5-7 mm greater than the beam flange width if runway includes sharp curves.
Now install the trolley on the beam by sliding one side frame out far enough to allow the
trackwheels to clear beam flange. Lift the trolley up so that the trackwheels are riding on the
beam and draw the side frames together and tighten the nuts snugly.

V. INSPECTION
To maintain continuous and satisfactory operation, a regular periodic inspection procedure
must be initiated so that worn or damaged parts can be replaced before they become unsafe.
The frequency of inspection must be determined by the individual application.
The following list gives an inspection procedure for normal usage under normal conditions.
When the unit is subjected to heavy usage or duty, moist or other adverse atmospheric
conditions, shorter time periods must be assigned. Inspection must be made of all parts for
unusual wear, corrosion or damage in addition to those specifically mentioned in the
succeeding list.
It is suggested that the unit be inspected monthly for wear damage and corrosion effects to all
parts with particular attention to the following:
1. Tightness of all fasteners.
2. Contactor and control station for burnt or pitted contacts and loose or corroded terminals.
3. Cables and leads for broken wires, loose or corroded terminals and damaged insulation.
4. Terminal board for loose or corroded connections.
5. Trackwheels for wear of tread, flange and bearings.
6. Gear portion of trackwheel and pinion for wear.
7. Check the wear of top hook to load plate in trolley.
8. Collector or power supply system for damage, wear corrosion and proper operation.
VI. MAINTENANCE
The following three steps are recommended for maintenance:
1. Once a month lubricate track wheel gear and pinion with grease or graphite grease.
2. Motor reducing gearbox uses planetary gear lubricated with cosmo No. 3 grease (Equivalent
to: Shell Unedo 3, Exxon Eastan 3, Mobil Cup Grease 3) for good maintenance. It is highly
recommended that the motor gearbox grease should be changed after 100 hours of
operation, then every 6 months or 2500 hours of normal service. Whichever comes first, the
grease needs to be changed as well.
3. The motor brake should be changed & be checked periodically for wear of brake lining and
disc. The gap between brake lining & disc can be adjusted by the brake adjusting hex. bolts
over the end of motor.
