Abstract: 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.

Abstract: A hydraulic tool for working on a workpiece. A housing is configured for holding. A motor is positioned in the housing. A battery is supported by the housing and operable to supply power to the motor. A drive mechanism is supported by the housing and includes a cylinder, a piston moveably supported in the cylinder, and a pump powered by the motor and operable to supply hydraulic fluid to the cylinder to move the piston relative to the cylinder. A head is supported by the housing and has an opening for receiving the workpiece therein. A spindle is operatively coupled to the drive mechanism such that operating the drive mechanism moves the spindle towards the workpiece within the opening in the head to work on the workpiece.

Abstract: A cylinder assembly, a system, and methods of operating a cylinder assembly and lifting a load. The assembly may generally include a housing; a hydraulic pump supported within the housing; a motor supported within the housing and operable to power the pump; a power source supported by the housing and operable to supply power to the motor; a cylinder coupled to the housing; a piston movably supported by the cylinder, the pump being operable to supply hydraulic fluid to the cylinder to move the piston to an advanced position; and a support member engageable with a work surface to support the assembly relative to the work surface, the support member being coupled to the cylinder. The assembly may have a maximum rated force capacity of at least 15 tons (t).
