ABSTRACT:
In a mechanical load brake for a hoist or other lifting device, a one-way device such as a helical wrap spring is fitted over the load brake shaft to automatically adjust for brake disc wear. A tang on the one-way device engages a drive hole in an input gear of the mechanical load brake. The diameter of the drive hole is selected so that the clearance of the tang in the drive hole corresponds to the optimal operating range. The one-way device moves around the shaft as the discs wear maintaining the optimal adjustment for the brake.
