  • Multi-stage hydraulic tool
    Patent number: 10093010
    Abstract: A hydraulic tool includes a handle having a trigger, a tool head, a tool body, a pump, a first actuator, a second actuator, and a conduit. The tool head has a first jaw and a second jaw. The tool body includes a first portion, an extension, and a second portion positioned between the handle and the tool head. The pump is activated by the trigger to displace a first fluid. The first actuator is moveable by the displacement of the first fluid to displace a second fluid. The second actuator is moveable by the displacement of the second fluid to cause movement of at least one of the first and second jaws. A conduit provides fluid communication between the first actuator and the second actuator.
