Lift device and method for controlling a lift device

A method for controlling a lift device having 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 method comprising:

• activating, in the event of a failure of the motor, the electric power module by the controller;
• and
• actuating, by the electric power module, 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.

A non-transitory computer readable storage medium having stored computer executable instructions for controlling a lift device having 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, wherein, the instructions when executed cause the controller to:

• activate, in the event of a failure of the motor, 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.
