ZOOMLION 00630878800001020 Crane Wire Rope Pulley Sheave
● ZOOMLION 00630878800001020 Pulley Technical Support
● Part number 00630878800001020 (drawing code 1087-880000-1020) is the genuine heavy-duty MC nylon wire rope guide sheave pulley engineered for ZOOMLION truck cranes and boom systems.
● Material number 00630878800001020 installs within crane boom head sheave nests, telescopic jib heads, and hoisting hook block assemblies. Precision machined with a smooth cable groove and integrated bearing bore, it redirects high-tension steel wire ropes smoothly during heavy lifting and winching, significantly reducing cable bending fatigue and friction-induced wire abrasion.
● Periodically inspect the rope groove radius for excessive uneven wear or flange chipping, ensure internal roller bearings rotate smoothly without axial play, and lubricate grease channels as specified.
