摘要： A hand-held hydraulic tool including a hydraulic drive system comprising a pump; and a user control system for at least partially controlling operation of the hydraulic tool. The user control system includes a first user control at a first location having a first pump activation control switch and a first hydraulic drive system drain control switch, and a second user control at a second location having a second pump activation control switch and a second hydraulic drive system drain control switch. The hydraulic tool is adapted to be controlled by a user at either of the first or the second locations.

摘要： A hydraulic tool working head including a frame, a ram and a connection between the ram and the frame. The frame has a first section with a hydraulic cylinder area, an opposite second section and a middle section connecting the first and second sections to each other. The ram is movably located in the hydraulic cylinder area and extends out of the first section of the frame towards the opposite second section of the frame. The connection between the ram and the middle section includes the middle section of the frame having two slots extending into opposite sides of the middle section and the ram having two cantilevered hook sections which generally face towards each other. The hook sections have ends slidably respectively located in the two slots of the middle section.
