E1: A no-load quick rise hydraulic lifting mechanism comprising, a hydraulic actuator and which comprise, a hydraulic cylinder having an extendible piston rod.
E2: An oil reservoir and a drive pump operably connected to the hydraulic cylinder, the drive pump comprising a drive cylinder and a drive piston and a drive pump over-pressure relief valve operably connecting the drive pump and the oil reservoir.
E3: A suction-discharge valve operably connecting the oil reservoir, the drive pump and the hydraulic cylinder during hydraulic-actuated lifting.
E4: An oil vacuum relief valve operably connecting the oil reservoir and the hydraulic cylinder, the oil vacuum relief valve allowing oil to flow from the oil reservoir into the hydraulic cylinder during mechanically-actuated lifting.
E5: A lift arm operably connected to the piston rod by a pin, the lift arm being pivot able about an axis and a mechanical actuator operably attached to the lift arm, the mechanical actuator comprising, a ratchet mechanism and an articulated linkage connecting the ratchet mechanism to the lift arm.
