Hydraulic Torque Wrench for Tight Clearance

摘要

A hydraulic torque wrench has a support partially sandwiched between first and second side plates. The support has hoop that extends beyond the edges of the plates so that the hoop has a smaller width than the wrench. An inner surface of the hoop defining a groove that receives a rib of a lever that fits against the hoop. This lever has an internal opening in which a socket disposes. A segment movable segment on the lever has teeth that ratchet with teeth around the socket. As the lever is reciprocated back and forth by an actuator on the wrench, the ratcheting between the lever and socket turn the socket and any nut disposed therein. The arrangement of the hoop, socket, and lever enable the wrench to be used in locations around nuts having tight clearances.
