BUYING a Hydraulic Torque Wrench
There are many different types of hydraulic torque wrench available, but the choice of torque wrench 
type and ancillary equipment depends on the application. We explain some key aspects to consider when purchasing the right torque wrench for your application.
Consider the accuracy and speed of operation that is needed for a project. It is best to choose a tool that gives constant torque output to provide high accuracy throughout its full stroke, as with the IBT Series square drives from WREN.
Consistent torque from one bolt to the next is crucial for applications ranging from fixed plant to earthmoving equipment, especially equipment under pressure, such as flanges and pipelines. Any bolt that may come loose causes downtime and maintained can cause failures in equipment. Where a large number of fasteners must have equal strength, tools such as the WREN Low profile Hex Cassette wrenches and IBT Square Drive units have precise repeatability across their entire range of torque.
The latest Hydraulic Torque Wrench do not incur a weight penalty, because even small increases in weight become larger when the same job is repeated again and again. To prevent Operator fatigue and Safety risks, choose a tool with weight-to-power, ergonomics, frequency of use and manoeuvrability around the job. Compare technologies, the low profile Hex Cassette Hydraulic wrenches for low clearance bolting applications and the versatile IBT series of Square Drive wrenches.
Generally, a Hydraulic torque wrench should have 50 per cent more capacity than required for a particular application. That leaves a capacity in reserve when necessary for cracking difficult bolted joints. For heavy applications, wrenches of twice the capacity are sometimes used.
It is important to service tools after use. Even the best tool is useless if it has to wait weeks for service. Hire Torque Tools can provide Support and Service for all its WREN Hydraulic Torque Wrench range, backed by a national sales and service network that extends into every corner of Australia.
Your Hydraulic High Torque Wrench, Multiplier or Hex Cassette Low Profile tool purchase should last you many years if properly Serviced and cared for. Any Tool can fail when misused and Technical Training is a must for all operators. Respect the power of Hydraulic Equipment and you will receive years of hard work from it!
