A braking apparatus for a rotary shaft connected to a load comprising brake shoe means for the shaft capable of limited angular movement about the shaft axis to cause release of the brake shoe means from a brake applied condition during application of starting torque to the shaft, and stop means operable during application of the brake shoe means to bring the shaft to rest, for preventing or reducing said limited angular movement. In this way the limited angular movement is eliminated during braking of the shaft to bring it to rest, whereby to provide substantially smooth braking, particularly when the shaft is operative on a load such as a conveyor having a long conveying belt. |
