ABSTRACT OF THE DISCLOSURE: A driving and braking apparatus usable with a load such, for example, as an uphill belt conveyor. The apparatus includes a motor for exerting driving torque on the load, a first control device for starting and terminating the driving torque, a brake for the load, a second control device for applying and disengaging the brake, a memory device adapted to receive instantaneous signals proportional to the torque fed to drive the load, and means interconnecting the first control device, the second control device and the memory device, in such manner that: (a) upon operation of the first control device to terminate the driving torque fed to the load the second control device operates to apply the brake and the memory device registers the magnitude of the signal of driving torque fed by the motor to the load at the instant of such operation of the first control device, and, (b) upon subsequent operation of the first control device to start the driving torque to the load the second control device operates to disengage the brake when the signal of torque being fed to the load at least attains the magnitude of the torque signal registered in the memory.
