OPERATION
The four most important aspects of trolley operation are:
1. Follow all safety instructions when operating trolley.
2. Allow only people instructed in safety and operation of this
product to operate the trolley.
3. Subject each trolley to regular inspections and a scheduled
maintenance program.
4. Be aware of the hoist and trolley capacity and weight of load
at all times. Do not overload.
WARNING
• Severe injury can be caused by: 1) falling under a moving
load, 2) being caught between a moving load and an object, 3)
tripping over an unseen object. To avoid injury, push to move
the trolley, do not pull. Pushing will allow you to stay out of the
path of the load and also look in the direction you are moving.
Initial Operating Checks
1. After trolley installation ensure the side plates are vertical.
2. With hoist installed, verify that hoist is centered below
trolley.
3. Raise a load equal to the lower of the rated capacities of
either the trolley or hoist a few inches (cm) off the floor.
4. Operate the trolley along the entire length of the beam.
5. Inspect trolley performance when raising, moving and
lowering test load(s). Trolley must operate smoothly prior to
being placed in service for general use.
6. Check rail stops are securely installed.
Using the Trolley
Plain Trolley
1. To move an unloaded hoist/trolley, push on the hoist load
chain.
2. To move a loaded hoist/trolley, push on the load or the hoist
load hook shank.
3. When operating the trolley keep load as close to the floor as
practical.
Geared Trolley
1. When facing the trolley hand wheel:
a. Pull down on right side of hand chain (clockwise
rotation) to move left.
b. Pull down on left side of hand chain (counterclockwise
rotation) to move right.
LUBRICATION
Trolleys are equipped with sealed bearings which require no
lubrication.
Pinion Shaft
Lubricate pinion before installing in geared side plate (3). For
temperatures -20° to 50° F (-29° to 10° C) use EP 1 grease or
equivalent. For temperatures 30° to 120° F (-1° to 49° C) use EP 2
grease or equivalent.
• When greasing pinion and geared wheels make sure excess
grease is cleaned off of trolley wheel riding surface and track
of beam. Failure to keep track and wheel contact surfaces
clean could affect the safe operation of the trolley.
Geared Trolley Wheels
Lubricate exposed trolley drive pinion and wheel teeth. Brush with
grease as often as necessary to keep teeth liberally covered. If the
grease becomes contaminated with sand, dirt or other abrasive
materials, clean off old grease and brush on new. For temperatures
-20° to 50° F (-29° to 10° C) use EP 1 grease or equivalent. For
temperatures 30° to 120° F (-1° to 49° C) use EP 2 grease or
equivalent.
INSPECTION
There are two types of inspection: the frequent inspection
performed by the operator and periodic inspections performed by
personnel trained in inspection and maintenance of the trolley.
Careful inspection on a regular basis will reveal potentially
dangerous conditions while still in the early stages, allowing
corrective action to be taken before the condition becomes
dangerous.
Any deficiency revealed through inspection must be reported to an
appointed person. A determination must be made as to whether a
deficiency constitutes a safety hazard before resuming operation
of the trolley or hoist.
Records and Reports
Some form of inspection record should be maintained for each
trolley, listing all points requiring periodic inspection. A written
report should be made quarterly on the condition of the critical
parts (e.g. wheels, bearings, side plates and hoist hanger shaft) of
each trolley. These reports should be dated, signed by the person
who performed the inspection, and kept on file where they are
readily available to authorized personnel.
