3.6 Preoperational Checks and Trial Operation
3.6.1 Refer to the hoist’s nameplate and record the hoist's Code, Lot and Serial Number in the space
provided on the cover of this manual.
3.6.2
WARNING
Confirm the adequacy of the rated capacity for all slings, chains, wire ropes and all
other lifting attachments before use. Inspect all load suspension members for damage prior to use and
replace or repair all damaged parts.
3.6.3
WARNING
Verify and correct all chain irregularities prior to operating the hoist. Refer to
Section 3.2 of this manual.
3.6.4 Measure and record the “k” dimension of all hooks on hoist. See Table 5-4 under Section 5
“Inspection”, of this manual.
3.6.5 Ensure that the hoist is properly installed to either a fixed point, or trolley, whichever applies.
3.6.6 If hoist is installed on a trolley, ensure that
trolley is properly installed on the beam, and
stops for the trolley are correctly positioned and securely installed on the beam.
3.6.7 Ensure that all nuts, bolts and split pins (cotter pins) are sufficiently fastened.
3.6.8 Pull down on the Pendant and ensure that the Cord Strain Relief Cable takes the force, not the
Pendant Cord.
3.6.9
CAUTION
Check supply voltage before everyday use. If the voltage varies more than 10% of
the rated value, electrical devices may not function normally.
3.6.10 Confirm proper operation.
Before operating read and become familiar with Section 4 – Operation in the ER2OM.
Before operating ensure that the hoist (and trolley) meets the Inspection, Testing and Maintenance
requirements of ANSI/ASME B30.16.
Before operating ensure that nothing will interfere with the full range of the hoist’s (and trolley’s)
operation.
3.6.11 Proceed with trial operation to confirm proper operation.
Verify that the controls agree with hoist direction. Make sure that depression of the up button lifts
the load chain and depression of the down button lowers the load chain hook. If the load chain
does not move in the correct direction when the push buttons are pushed, the power supply is
phased incorrectly. In this case, turn off the power source or breaker switch
then reverse any two of
the three wires at the power source. The hook will then move in accordance with the directions of
the push button.
Perform inspections per Section 5.2, “Frequent Inspections” in the ER2OM.
