Hydraulic Torque Wrench - Square drive

Hydraulic Torque Wrench - the hydraulic spanner!

Operated by a Hydraulic Cylinder within the tool-body, this pushes through the ratchet gear, directly connected to the Square drive. With minimum moving parts, the hydraulic power is conveyed to the socket. Driven by High-Pressure Hydraulic pump via 4:1 flexible hoses. These pumps use a Variable pressure regulator - 1,500psi to 10,000psi . By changing this pressure you control the torque output. A Torque Chart showing calibrated Torque & Pressure figures for torque setting sets the range of each tool. Once set, the tool will stop or stall the tool to the pre-set pressure: thus the set torque is achieved.

These Tools use only Impact Sockets with a thicker wall size designed for the high Torque pressures. Square Drive Sizes start from 1/3" up to 2-1/2" . There are nine tool sizes in total giving from 180 to 70,000 Nm (130 to 52,000 Ft Lbs ).

Hydraulic torque tools have the highest torque repeatability and accuracy as there are less external variables. These tools easily achieve + or - 3% accuracy torque or better. With Repeatability around 1% to 3%.

Hydraulic Torque tools are Operator friendly, don't rely on Operator effort or high air pressures. The Hydraulic Power driving them is much more reliable and consistent. Hydraulic torque tools offer the greatest output for their weight and size. These attributes made them to Heavy Industry Tool of choice and very popular. They offer production increases for simple light industry tasks, major maintenance shutdown applications right through upto the heaviest Industry needs.
