Calling on the Experts

Profile

A global manufacturer of industrial lifting equipment.

Customer Challenge

When our customer needed fast turnaround on a 37-ton alloy swivel shank hook with a fabricated bearing retainer nut they called Assembly Specialty.

Assembly Specialty Solution

The hook shank was machined to the appropriate diameter and threaded with 3” – 8 UN 2B threads on one of our dozen computer controlled lathes. The bearing retaining nut was then cut from 7” diameter AISI 4130 alloy steel round stock and machined to accept a crane hook thrust bearing ring, then threaded to mate perfectly with the threads on the hook shank.
