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.
Trolleys are equipped with sealed bearings which require no
lubrication.
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.
Frequent Inspection
On trolleys in continuous service, frequent inspection should be
made at the beginning of each shift. In addition, visual inspections
should be conducted during regular service for any damage or
evidence of malfunction.

OPERATION
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.
Operation
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.
LUBRICATION
INSPECTION
1.
OPERATION. Operate the trolley so that it travels 3 feet
(1 metre). During the 3 feet (1 metre) of travel, check for
visual signs or abnormal noises which could indicate a
problem. Check for smooth operation. Do not operate the
trolley until all problems have been corrected.
Frequency of periodic inspection depends on the severity of usage:
NORMAL
yearly
Disassembly may be required for HEAVY or SEVERE usage.
Keep accumulative written records of periodic inspections to
provide a basis for continuing evaluation. Inspect all the items in
"Frequent Inspection." Also inspect the following:
1.
FASTENERS. Check retainer rings and nuts. Replace if
missing or damaged and tighten if loose.
2.
ALL COMPONENTS. Inspect for wear, damage, distortion,
deformation and cleanliness. If external evidence indicates
the need, disassemble. Check shafts, wheels, bearings and
side plates. Replace worn or damaged parts. Clean and
reassemble.
3.
SUPPORTING STRUCTURE. Check for distortion, wear
and continued ability to support load.
4.
TROLLEY. Check that the trolley wheels track the beam
properly and total clearance between each wheel and beam
equals 1/16 to 1/8 in. (1.6 to 3.2 mm). Check side plates for
spreading due to bending. Repair as necessary.
5.
LABELS. Check for presence and legibility. Replace if
necessary.
