RECORD OF SATISFACTORY CONDITION
After receiving the unit and before using it for the first time, create a record that describes its
appearance and operation. Thoroughly photograph the unit from multiple angles. Take close range
photographs of the labels, data plates, and tags, drive wheels, the equalizer pin, the left and right ear
cases, the chain ( model E-MT-C), and fasteners. Move the trolley several feet in each direction along the
beam flange. Record your observations about how the unit looks and sounds as it moves. Make note of the
effort required to move the trolley. Collect all notes and photos in a file. The file is a record of the trolley in
satisfactory condition. Compare the results of all inspections to this Record to determine whether a
component is in satisfactory condition or requires repair or replacement. If issues are discovered during an
inspection, DO NOT use the trolley until it is restored to satisfactory condition. Cosmetic changes, like
damaged surface coating (paint or powdercoat) are not changes from satisfactory condition. However,
touchup paint should be applied wherever the finish is damaged as soon as damage occurs.
LOAD TESTS
After creating a RECORD OF SATISFACTORY CONDITION and before using the trolley for the first time, a
qualified person should conduct a load test. The test load should be 125% of the capacity/rated load. For
example, if the capacity is 1,000 lb. (454.5kg), then the test load should be 1,250 pounds (568.2kg). Attach
the unit to an appropriately rated overhead lifter. Raise the unit until it is suspended. Leave the unit
suspended for a few minutes. Return it to the ground and unload it. Perform a Frequent Inspection and a
Periodic Inspection as described in INSPECTIONS & MAINTENANCE (below) to confirm that the trolley
remains in satisfactory condition. The trolley must undergo load testing before being returned to service any
time it is repaired.
INSPECTIONS & MAINTENANCE
Inspections and repairs should only be performed by qualified persons. Compare the results of each
inspection to the RECORD OF SATISFACTORY CONDITION (the “RECORD”). Do not use the trolley unless all
parts are in satisfactory condition. Replace parts that are not in satisfactory condition before returning the
trolley to service. DON’T GUESS! If you have any questions about the condition of your hopper, speak with
TECHNICAL SERVICE personnel. The phone number is provided on the cover page of this manual. Never
make temporary repairs of damaged or missing parts. Only use approved replacement parts.
Frequent Inspection
At least once per week, inspect all functional operating mechanisms.
i. Assess Operation:
1. Move the trolley along the beam flange and evaluate its operation. The trolley should roll
smoothly along the flange.
2. Check both side plates of the trolley for evidence of spreading, bending, warping, and cracking.
Clearance between each drive wheel or tooth gear and the beam flange should be no more
than 1/8in. to 1/16in. (1/8-1/4 inch overall). See INSTALLING THE TROLLEY diagram, “Maximum
permissible gap”, on p. 4.
ii. Drive wheels (EM-T) or tooth gears (EM-T-C), drive spindle, equalizer pin, and chain wheel (EM-T-C):
Visually inspect each component for cracks, warps, significant wear, and other forms of damage or
deterioration. Confirm that all are in satisfactory condition.
Periodic Inspection
At least once every 6 months, perform the following inspections:
a. Perform a “Frequent Inspection”.
b. Fasteners: Check bolts, nuts, washers, etc. Make sure that connections are tight.
c. Evidence of wear, corrosion, cracks, or deformations of operational components: Examine left
and right gear cases, drive wheels, tooth gears and drive spindle (-C models), equalizer pin,
chain (-C models), and bearings.
d. Labels: Labels, plates, and tags must be easily readable and affixed or otherwise attached to
the trolley as shown in the LABELING DIAGRAM on p. 6. NOTE: Label appearance and content is
subject to change over time, and consequently, replacement labels might differ from labels
shown in the manual supplied with the unit.
