Abstract
An overload indicator for a hoist includes first and second blocks that connect to the lifting medium (a chain for a chain hoist) at spaced locations. The first and second blocks are held at a spacing by indicator bands so that the lifting medium is slack between the blocks. The indicator bands have weakened portions to deform, stretch or break when subject to a load over a threshold, such as over a lifting capacity of the hoist. Covers are provided over the indicator bands that are closely spaced to define an indicator gap. If the indicator bands stretch, the indicator gap increases to indicate an overload condition.
