Hydraulic torque wrench
A hydraulic torque wrench is a specialised tool used in industrial applications to apply a specific amount of torque (rotational force) to fasteners such as bolts and nuts. It uses hydraulic pressure to generate controlled rotational force, enabling accurate and controlled tightening or loosening of fasteners in various mechanical and construction tasks. Hydraulic torque wrenches are valued for their ability to achieve precise torque levels, ensuring proper assembly, structural integrity, and safe operation of equipment and structures.
The tool typically consists of a hydraulic cylinder, a reaction arm or head, and a hydraulic pump. The hydraulic pressure is directed to the cylinder, causing it to exert rotational force on the fastener. The reaction arm or head prevents the tool from rotating along with the fastener, ensuring that the applied force is directed solely onto the fastener.
Hydraulic torque wrenches are used in a wide range of industries including construction, manufacturing, oil and gas, power generation, and more. They are particularly crucial for applications where accurate and controlled torque is essential, such as assembling large machinery, tightening bolts on critical structures, and maintaining the integrity of joints in various engineering projects.
