Hollow hydraulic torque wrenchDetailed product description：

FYK hollow hydraulic torque wrench has a compact structure, small volume, light weight, and high output torque, making it a powerful tool for nut disassembly and bolt pre tightening.
Can be used in confined spaces such as turbine covers and valve flanges, with multiple heads per machine and quick change capability.

The FYK hollow hydraulic torque wrench is equipped with a high-quality specialized packaging box, which is resistant to strong impact, oil and water, making it very suitable for on-site environments and also convenient for equipment storage.
Thin socket wrench heads can be used in places with limited space or strict industrial and mining requirements.
The sleeve wrench, working oil cylinder, and reaction arm structural components are assembled as a whole, reducing the weight of the entire set of tools and lowering the workload of workers.
Each stroke rotates at an angle of ≥ 15 °, resulting in high work efficiency and fast movement speed.
Series design, for bolts and nuts of different specifications, only different sizes of wrenches need to be replaced to work.
The design accuracy is ± 5%, and the repeatability accuracy is 98%.
