3.6Preoperational Checks and Trial Operation

3.6.1Refer 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.

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.

Verify and correct all chain irregularities prior to operating the hoist. Refer to Section 3.2 of this manual.

3.6.4Measure and record the “k” dimension of all hooks on hoist. See Table 5-4under Section 5 “Inspection”, of this manual.

3.6.5Ensure that the hoist is properly installed to either a fixed point, or trolley, whichever applies.

3.6.6If hoist is installed on a trolley, ensure thatƒtrolley is properly installed on the beam, and

ƒstops for the trolley are correctly positioned and securely installed on the beam.

3.6.7Ensure that all nuts, bolts and split pins (cotter pins) are sufficiently fastened.

3.6.8Pull down on the Pendant and ensure that the Cord Strain Relief Cable takes the force, not the Pendant Cord.

Check supply voltage before everyday use. If the voltage varies more than 10% of the rated value, electrical devices may not function normally.

3.6.10Confirm proper operation.

ƒBefore operating read and become familiar with Section 4 – Operation in the ER2OM.

ƒBefore operating ensure that the hoist (and trolley) meets the Inspection, Testing and Maintenance requirements of ANSI/ASME B30.16.

ƒBefore operating ensure that nothing will interfere with the full range of the hoist’s (and trolley’s) operation.

3.6.11Proceed with trial operation to confirm proper operation.

ƒVerify 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.

ƒPerform inspections per Section 5.2, “Frequent Inspections” in the ER2OM.
