HARRINGTON Hoist RHN02D-33A-20D-1

Lubrication and Cleaning – Refer to Section 6-2.

WARNING: Be certain that the replacement wire rope is obtained from Harrington Hoists, Inc. and is the correct wire rope for the hoist.

WARNING: Twisting in the rope prejudices safety and service life. Remove any twists!

CAUTION: The hoist must be properly powered and operational in order to perform the following procedures.

CAUTION: When replacing Wire Rope, check for wear on mating parts, i.e. Drum, Sheaves, Hook Block Sheaves and replace if necessary.

Lower the Hook Block to the lowest possible position without touching the floor or ground.

Remove the Wire Rope Clamp (G) and loosen the Wire Rope until the Terminal Wedge (H) can be removed from the Anchorage Assembly (F) (see Figure 6-4).

Remove (unreeve) the Wire Rope from the Bottom Block and all Sheaves.

Warning: This inspection requires a designated or qualified person.

New, re-installed, altered, or modified hoists/trolleys inspected for compliance?

All functional operating mechanisms checked for maladjustment and unusual sounds?

Hoist and trolley checked in accordance with ANSI/ASME B30.16?

All limit switches and associated components operational?

Upper limit devices checked in accordance with ANSI/ASME B30.16?

Hoist/trolley braking system operational?

DANGER: Before proceeding, ensure that the electrical supply for the hoist or trolley has been de-energized (disconnected). Lock out and tag out in accordance with ANSI Z244.1 “Personnel Protection –Lockout/Tagout of Energy Sources”. The hoist must be unloaded and the bottom hook block set down.

Measure air gap with feeler gauge

Feeler gauge pushed in at least as far as depth 'a' and does not catch on shoulder

Max. permissible air gap (S) has been reached

Brake disc (brake rotor) needs to be replaced

For proper performance the Wire Rope must be maintained in a clean and well lubricated condition.

The rope should be lubricated every 3 months (more frequently for heavier usage or severe conditions).

To lubricate the rope, first remove any dirt, grime, moisture or other accumulations of contaminates. Then coat the Wire Rope with grease in Table 6-1. Ensure that the lubricant is applied to the entire surface of the rope over its entire length.

For dusty environments, dry lubricants are suggested.

For conditions not permitting lubricant to fall off the wire rope, consider using non-dripping lubricant.

6.2.2 Wire Rope Drum, Hook Block and Sheaves:

The drum, hook block and sheaves should be lubricated every 3 months (more frequently for heavier usage or severe conditions).

Lubricate the Drum, Hook Block and Sheaves with grease in Table 6-1.

DANGER: Before proceeding, ensure that the electrical supply for the hoist or trolley has been de-energized (disconnected). Lock out and tag out in accordance with ANSI Z244.1 “Personnel Protection –Lockout/Tagout of Energy Sources”. The hoist must be unloaded and the bottom hook block set down.

Measure air gap (S) with feeler gauge (F). When measuring, ensure that the feeler gauge is pushed in at least as far as depth 'a' and does not catch on shoulder.

If the max. permissible air gap (S) has been reached, the brake disc (brake rotor) must be replaced.
