摘要： A battery powered hydraulic tool including a frame; a battery connected to the frame; a motor connected to the frame and adapted to be powered by the battery; and a hydraulic pump connected to the motor by a gear reduction transmission. The motor and gear reduction transmission are adapted to output a torque of the least about 160 oz-in with the gear reduction transmission being adapted to provide a gear reduction of between about 8:1 to about 15:1 or less, and the hydraulic pump being adapted to output at least about 6000 psi of pressure or more.

摘要： A hydraulically actuated tool comprising a frame; a hydraulic fluid pump connected to the frame; a ram movably connected to the frame and adapted to be moved relative to the frame by hydraulic fluid pumped by the pump; and a hydraulic fluid reservoir connected to the pump. The reservoir is located proximate an exterior portion of the frame along a path of at least about 180°0 relative to a longitudinal axis of the tool. The reservoir does not extend beyond a rear end of the frame.
