The Hoist Dynamometer-An Instrument for Full Scale Evaluation of Band Brake Materials

This paper describes a hoist dynamometer capable of reproducing field conditions for the purpose of providing comparative data on friction materials used on band brakes and clutches by the crane and hoist industry. Performance qualities essential to the braking system are recorded for both automatic and manual operation. The dynamometer enables the testing to be performed under controlled conditions which can be both repetitive and reproducible.
