The invention of the hydraulic torque wrench came about when auto workers in the 1970's needed a tool that could maintain efficiency and increase productivity on large scale auto projects within the workplace. The science behind this power tool roots down to the pumping unit that exerts huge amounts of pressure which is then translated into torque.

Simply speaking, the hydraulic torque wrench is a type of wrench which indicates the amount of torque applied to a bolt or nut through a gauging device. Usually, manual torque wrenches are used for tightening because of its convenience and affordability. With the hydraulic torque wrench, you have control with regard to the amount of pressure you apply as compared to the mechanical variant.

Auto companies, who hold the majority in the usage of this tool, have always sought for cost-efficiency in running the business.
The hydraulic wrench brings in loads of advantages to a company. You can have 30% more accuracy with this power tool compared to using the mechanical wrenches. It drastically trims down the operation time, enabling the workers to do more projects per day. You can do this by making sure that the amount of torque is calculated before a bolt is fastened. If bolts are tightened insufficiently, bolts may be subject to vibrations that could damage the structural support and come apart. Contrarily, if they are too tight, bolts are subject to breakage.
However, there are certain precautions you have to ascertain. For you to attain the greatest accuracy, ensure that your workers are trained well and supervised. You should follow standard maintenance procedures to keep fasteners in quality shape , including the application of lubrication and thread cleaning. Lubrication lessens friction and increases manipulability. Remember that the wrench should be perpendicular to the axis of the bolts to attain the sufficient amount of force. If you are working on a circular or an oval joint, you should use a cross-bolting pattern. It's advisable for you to have earlier records of the amount of torque used on the same tasks; if a certain amount of torque worked sufficiently on a certain task, most likely you'll have similar results.
In spite of its hefty price tags, the hydraulic torque wrench make sense economically. The savings that firms realize through great accuracy, cost-efficiency, and reliability of fastened bolts will eventually offset the initial investment.
