Torque Wrench

Highly Tensile Strength Hydraulic Bolting Tools

A hydraulic torque wrench is a power tool designed to exert torque on a fastener to achieve proper tightening or loosening of a connection through the use of hydraulics. A torque wrench is applied to the nut either directly or in conjunction with an impact socket.

Features

  • Al-Ti alloy integrated machine has high strength, high tenacity with light weight.
  • The 360º×180º rotating oil connection has no limitation in used space and is convenient to be operated.
  • The actuating shaft is released by torque and can fast switch between screwing up and dismantling.
  • The hydraulic piston and power head have a small shape, compact structure and small operation radius.
  • The nut rotation angle in single operation is large and the hydraulic piston has a quick return stroke. The work efficiency is high.
  • The reactive force is on one straight line, which can decrease the inner torque abrasion.
  • The constant torque output provides the high precision for wrench in the whole working process.
  • The maintenance is simple and does not need the special tools.
  • The precise ratchet wheel is used in the inside of the wrench, with the precision up to ±3%.
