irregular sounds or other evidence of jamming, wedging
or malfunctioning.
4.
Supporting Structure.
Check the supporting structure for distortion, excessive
wear and continued ability to support the load.
5.
Trolley
Check that the trolley wheels run and track the beam
properly and that the clearance between the beam and
trolley wheel flanges is 1 to 2 mm maximum per side.
Check that wheels, bearings shafts, gears or rollers are
not excessively worn, cracked or distorted and inspect the
side plates for opening due to bending. Do not operate
the trolley until any problems have been identified and
fixed.
6.
Nameplate.
Check for presence and legibility. Replace if necessary.
Trolleys that has been idle for a period of 1 year or more
shall be inspected in accordance with periodic inspection
before being placed into service.
14.3 Records and Reports
An inspection record should be maintained for each
trolley, listing all points requiring periodic inspection. A
written report should be made monthly on the condition of
the critical parts (e.g. wheels, bearings, side plates and
hanger shaft) of each trolley. These reports should be
dated, signed by each person who performed the
inspection, and kept on file where they are readily
available to the authorized personnel.
15 Troubleshooting
This section provides the information necessary for
troubleshooting the Elephant Lifting Products
Trolleys. The troubleshooting guide provides a
general outline of problems which could be
experienced with normal use of the trolley. Table 1 lists
the symptom, the possible cause, and the possible
remedy for the trouble being experienced.
Table 1: Troubleshooting
16 Maintenance
General maintenance should be performed in accordance
with the requirements of ASME B30 Volume and the
conditions and practices of a particular workplace.
Elephant Lifting Products
trolleys are extremely robust
and require little maintenance. They are suitable for
use in explosion-hazardous areas as well as in
areas with increased concentrations of soot and dust,
high humidity and at ambient temperatures of – 20° C
up to approx. + 70° C if they are not heated above
this level due to external influences. The thermal
endurance of chains and hooks is up to + 150° C.
In order for the trolleys to operate safely and reliably over
a period of many years, compliance with maintenance
and inspection intervals is of immense importance. If the
trolley is being operated in a harsh environment that leads
to accelerated wear, then the maintenance intervals
should be reduced.
•
Never perform maintenance on the trolley while it is
supporting a load.
•
After performing any maintenance on the trolley, test
trolley as described in the “Safe Operating
Instructions”, Section 7, before returning trolley to
service.
