If you’re involved in construction, fitting or any other kind of work you might find yourself in situations where your conventional socket wrench isn’t enough for meeting your requirements. In such case, you can opt for a hydraulic wrench or electric torque wrenches. These tools have been used by homeowners as well as professionals for a long time and you can buy hydraulic torque wrench of different varieties as each one of these power tools is required for several purposes.
Knowing the basics
The machine has simple basics as a hydraulic torque wrench is designed for exerting a higher torque on different types of fasteners. The main benefit with this type of wrench is that you can securely and quickly loosen and fasten different nuts. These would be helpful for applying an amount of torque towards lubricated fasteners much beyond what a human was able to muster, typically in conjunction with impact sockets. Firstly, these got introduced in 1960’s, but later these considerably evolved with consistent updates in designs and manufacture.
Working mechanism
Amidst this advanced array of tools, we get modern hydraulic wrenches, one which is light because of exotic alloys, with smaller nose radius for increasing spaces that fit well. Possessing multi-position reaction members, and you can run many such tools of single power pack simultaneously. These wrenches make use of hydraulics for tightening or loosening nuts and bolts. These machines apply a predetermined torque to make the operation quieter by leveling noise. With the present varieties of torque wrenches, you get better efficiency and precision in addition to flexibility in use.
The hydraulic torque wrench has a gearbox which relates to an electric motor. The gearbox is designed in a way that it quickly absorbs torque, letting the user control wrenches without putting on much effort. Typically, these would be used when there isn’t any requirement for torque strength accuracy being used on nut and bolt, or when a stubborn nut must be removed. These gearboxes can be of ratios of around 4000:1. And this can be adjusted well by keeping a control on voltage.
Benefits of Hydraulic wrenches
The reason these machines are called hydraulic torque wrenches is that it generates torque through a hydraulic power and is self-ratcheting. The tools have a precise way of measuring the torque that has been applied to the fastener. There are many renowned manufacturers of hydraulic wrenches with varied designs and make and all these come with higher accuracy levels.
With these wrenches, you get an accuracy rating of around +/-3% with a higher rate of repeatability. With this feature, it becomes suitable for large bolts that are required for the higher level of accuracy. The best benefit of hydraulic torque wrench is that you won’t need to care much about performance, but many users have reported that these are much quieter compared to pneumatic wrenches of similar output.
As these machines operate on electricity you can buy waterproof models as well when you buy hydraulic torque wrench. New buyers might confuse it with impact wrenches due to their similar designs, but in fact this would be quite a different tool, and is also different from hydraulic torque wrenches. Being concerned about the job every tightening and loosening task is possible quickly with hydraulic wrenches.
If you’re primarily concerned about safety accuracy and speed for your bolt fitting tasks, then hydraulic torque wrenches with their higher power capabilities would be the right product for your requirements.
