CABLE SHEAVE-4inchDIA.
Sheaves are expendable items. Sheaves and pins should be replaced when worn. Use of sheaves and pins with excessive wear will lead to reduced service life of cables.
How to Check for Wear:
Inspect sheaves (pulleys) in yoke ends with lift in lowered position or resting on the locking latches.
a. Hold lowering handle down and pull on cable in column to create slack in cables.
b. Check for excessive side to side wobble. Grasp rim of sheave and attempt to wobble (tilt) side to side.
If sheaves wobble (tilt) more than 3/16” (4.8 mm) side to side or move up and down on shaft more than 1/32” (0.8 mm), the sheave and pin (shaft) should be replaced, refer figures below.
c. Check sheaves and replace if cracks are found.
d. Check for ease of rotation. If sheaves do not turn freely, the sheave and sheave pin should be removed, inspected, lubricated, and reinstalled or replaced.
Fully raise lift. Inspect sheaves (pulleys) in runway ends with lift in raised position.
a. Visually inspect alignment of sheaves, see figure above. Misalignment of sheave(s) indicates excessive wear; the sheave(s) and sheave pin should be removed and inspected. Replace as required.
b. Hold lowering handle down to lower lift onto latches. Pull on cables under runway to create cable slack
c. Check for excessive side to side wobble. Grasp rim of sheave and attempt to wobble (tilt) side to side, refer to figures above. If sheaves wobble (tilt) more than 1/16” (1.6 mm) side to side, or move in and out more than 1/32” (0.8 mm), the sheave and sheave pin (shaft) should be replaced, refer to figure below.
