Abstract
A climb assist system is disclosed that dynamically adjust the rate and level of assist of a climber as the climber needs may change over the period of traverse of the ladder. A sensor detects the state of a person, such as the load exerted by the climber on a ladder exerts on an assist rope, to provide an upward support force on the climber to compensate the climber's weight. Additionally, a sender is provided to transmit the load data to a receiver and a receiver to receive the data from the sender. A controller interprets the received data and thereafter provides control through a controlled motor and drive to provide energy to the assist rope.
