What is a hydraulic torque wrench?
A hydraulic torque wrench is a tool used to apply torque to a joint or bolt. It uses the power of hydraulic fluid to rotate the wrench handle and apply pressure to the bolt or joint. Torque wrenches are helpful when installing or removing parts in difficult-to-reach places, and they can also be used for general repairs.
Types of hydraulic torque wrenches
There are many types of hydraulic torque wrenches available on the market today. Some of the more common types include low profile, square drive, and dial-style torque wrenches. Each type has its own unique benefits that can be useful in certain situations. Low-profile torque wrenches are often considered to be the most compact option available. They’re also typically the least expensive option, making them a good choice if you only need a wrench for occasional use. They have shorter handles and smaller heads, which make them ideal for tight spaces or areas with limited space. Square drive torque wrenches are similar to low profile torque wrenches in terms of their size and capabilities. However, they have wider heads and longer handles, which makes them easier to use when working with large bolts or screws.
Factors to consider when choosing a hydraulic torque wrench
The decision to buy or use a torque wrench is not an easy one. There are many factors to consider, including the type of construction being worked on, what kind of torque and size range the wrench covers, and the user’s experience with using torque wrenches. Here are some key things to keep in mind when choosing a torque wrench:
- The type of construction: Many reputable manufacturers produce hydraulic torque wrenches that are robust, reliable, and fit for a variety of purposes. But heavy users often look for higher-end products, such as the RIVERLAKE RLW series (square drive) and RHW series (low profile). At this level, expect hassle-free ownership, superior quality, and extra features, such as quick-change cassettes.
- Torque range: A torque wrench typically has a range of Torque (in pounds-ft) that it can apply. This is important because different bolts and screws require different amounts of torque to tighten them properly. A torque wrench has a dial indicator, usually calibrated in Newton-meters or pounds-ft. This is used to measure the amount of force needed to tighten a bolt or screw. -Calibration gauge A calibration gauge is used to measure the torque applied to a bolt or screw. This is important in order to ensure that the correct amount of torque is being applied.
- Torque range and accuracy: Torque wrenches are not always strictly accurate. The accuracy of a torque wrench can be affected by many variables, such as the type of metal being tightened, the length of the bolt or screw, and the amount of slippage on the wrench’s handle. In some cases, a torque wrench’s accuracy can be significantly reduced if it is used on an object that is too large or heavy for its size.
How to use a hydraulic torque wrench safely
Hydraulic torque wrenches are a valuable tool for mechanics and car enthusiasts. However, like any tool, they can be used incorrectly if not handled correctly. Here are five tips to help you use your hydraulic torque wrench safely:
- Read the instruction manual thoroughly before using your torque wrench.
- Use caution when adjusting the wrench’s settings. Over-tightening the screw can cause damage to the tool or your vehicle.
- Always wear safety gloves when using a torque wrench, and keep both hands clear of the moving parts while tightening or loosening the screws.
- Make sure that the area around the torque wrench is clean and free from debris before using it, in order to avoid causing damage during use.
- Store your torque wrench properly after each use so that it remains operational and safe for future use.
