Drop Lifter

A commonly seen application in Automotive Assembly plants, drop lifers are used to transfer sub-assemblies vertically through various processes.  These lifters are often used at high speed with sudden stop and starts creating a large amount of extra load from inertia.  Commonly Tsubaki Super Chains are used for their adherence to standard dimensions and high strength ratings.

Drop-Lifters should be checked often for stretch.  However, it is important to check the portion of the chain that actually engages with the sprocket or traction wheel.  Large spans of Drop-Lifter chain are essentially hanging static loads as they do not engage with the sprocket.  These section rarely succumb to stretch, but rather should be checked for cracking or pin-turning.
