Abstract:
Apparatus and methods for lifting loads are described. The load lift includes a support frame and a lift assembly with main cylinder and at least one standby cylinder connecting a rotatable cross beam with a clamp plate. A rotary actuator assembly is connected to the lift beam to move the lift assembly out of the way while not in use by rotating the lift assembly from a lift position to a standby position.
