Abstract:
A drum rotation indicator for indicating the speed of raising and lowering a load by a crane winch. A rate generator connected to the winch develops electrical pulses having a frequency proportional to winch rotational speed. A solenoid having a movable plunger is mounted in the cab of a crane where the vibration of the plunger can be sensed by a crane operator. Pulses from the rate generator are amplified and coupled to the solenoid to cause the plunger to vibrate at a rate corresponding to pulse frequency.
