Abstract
A climb assist system is disclosed that adjusts the rate and level of assist of a climber and starts/stops the level of assist as the climber needs may change over the period of traverse of the ladder. A sensor may detect a change in the operating state of a motor in the climb assist system. For example, the change in state may indicate a change in the load exerted by the climber indicating that the climber intends to start or stop an active climb. The climb assist system may then adjust the inputs to the motor to initiate a climb or terminate a climb.
