hoisting cycle
The periods of acceleration, uniform speed, retardation, and rest. The deeper the shaft, the greater is the ratio of the time of full-speed hoisting to the total hoisting cycle. For shallow shafts there may be very little time at full speed, retardation beginning almost at the end of the accelerating period.
