摘要:
A hydraulic tool including a frame having a hydraulic conduit system; a ram movably connected to the frame; and a multi-speed ram advancement system for advancing the ram in at least two different rates of movement on the frame. The multi-speed ram advancement system includes a hydraulic pump connected to the hydraulic conduit system of the frame; and a conduit tube extending into a hydraulic chamber inside the ram and fixedly connected to the frame. The conduit tube is adapted to conduit hydraulic fluid from the hydraulic conduit system into the hydraulic chamber inside the ram. The conduit tube is axially rotatably connected to the frame and longitudinally stationarily fixed to the frame.
