Abstract
An improved load brake mechanism for hoists allows free movement of load supporting means connected with the hoist. The mechanism will stop the supporting means whenever the means achieves a predetermined velocity or acceleration. The braking mechanism allows the convenience of a free chain mode without the risk of an uncontrolled load on the hoist.
