Abstract

A lift device includes a lift mechanism movable to raise or lower a platform relative to a base, a manifold having a valve actuatable to deliver fluid to a hydraulic actuator configured to move the lift mechanism, a motor for driving a pump to deliver fluid to the manifold, an electric power module in communication with the manifold, and a controller in communication with the electric power module. The controller is configured, in the event of a failure of the motor, to activate the electric power module to actuate the valve of the manifold to enable gravity lowering of the platform by the lift mechanism from a first position to a second position below the first position.
