A cylinder assembly having a housing, a pump supported within the housing, a motor supported within the housing and operable to power the pump, and a power source supported by the housing and operable to supply power to the motor. A cylinder has a first end, an opposite second end, and a sidewall extending therebetween. A piston is movably supported by the cylinder, the pump being operable to supply hydraulic fluid to the cylinder to move the piston relative to the cylinder at least from a retracted position to an advanced position. A frame is coupled to the sidewall of the cylinder and supporting the pump and the motor.
