What is hydraulic torquing?
Hydraulic torquing is a mechanical fastening method that provides a torque force to a fastener. By using hydraulic liquids, hydraulic torque wrenches can provide high amounts of torque to fasteners. Hydraulic torquing is often used in the mining, oil and gas, and shipbuilding industries.
How do you adjust a hydraulic torque wrench?
Drive to do this simply push the release button on the opposite side of the square. Drive pull the shaft out and reinsert. It into the other side of the tool then adjust the positioning.
What is a low profile hydraulic torque wrench?
Low-profile hydraulic torque wrenches slip over a bolt in tight or recessed spaces. Low-profile hydraulic torque wrenches consist of a cassette that fits a specific bolt size and a drive that connects to a hydraulic pump to provide power. Cassettes can be changed to match the bolt shape and diameter.
How do you use the torque wrench in Hytorc?
Ratchet the wrench until it stalls at the preset pressure and the socket will no longer. Turn be patient on the last few strokes as the socket will leave very slowly. If in doubt always.
How is hydraulic torque applied?
As hydraulic oil flows to the torque wrench, the piston advances inside the torque wrench, causing the hex ring to rotate around the nut. (See the video below). The piston is retracted, causing the ratchet to return to its starting position, and the process is repeated until the target pressure has been achieved.
How accurate are hydraulic torque wrenches?
±3%
Hydraulic torque wrenches typically offer accuracy of ±3% and have a high degree of repeatability making them well suited to applications where large bolts are involved and a high degree of accuracy is required.
What does the torque output of a hydraulic wrench depend on?
Both the minimum and maximum torque depend on the capacity and size of the hydraulic equipment. Hydraulic torque wrenches are especially useful on large bolts (1-inch diameter or greater).
How does a torque multiplier wrench work?
Torque multipliers work with the use of an epicyclical gear train that has one or more stages. Each stage of the gear range will multiply the applied torque. This torque is applied to the input gear, causing the planet gears that are situated around it to rotate.
What type of wrench should be used to tighten a bolt to a specified degree of tightness?
torque wrench
A torque wrench is used where the tightness of screws and bolts is crucial.
How do you use a hydraulic torque machine?

What is the purpose of torquing?
In simple terms, you need torque to create tension in a bolt. You use torque to turn a nut onto a bolt and then to stretch the bolt, making it a solid spring that clamps the two materials together.
Who invented the hydraulic torque wrench?
George Sturdevant
Hydraulic Torque Wrenches were first conceptualised in the early 1960s and later invented by George Sturdevant in 1968.
Is 4% accuracy for a torque wrench good?
As stated above, most torque wrenches have an accuracy between 3-5%. Let’s talk about 100 FT LB torque wrench at 4% accuracy. That would be an accuracy of 4 FT Lb. In this specific case they stated ” Every time we get our torque wrenches back from calibration, I get complaints that they are not reading properly.”
What units does the hydraulic torque wrench read out in?
Hydraulic torque wrenches operate at high pressure (up to 10,000 PSI) and can produce torque outputs over 50,000 ft./lbs. These are very precise tools, with an accuracy range of plus or minus three percent and a repeatability of plus or minus one percent.
How do you calculate torque with torque multiplier?
M1 = M2 x L1 / L2.
What is the difference between a torque wrench and a torque multiplier?
Multipliers don’t have the long handles that can make tools such as torque wrenches or cheater bars inconvenient, allowing them to achieve proper torque even in tight spaces.
What are the 3 types of torque wrenches?
There are four basic types of torque wrenches, each with slightly different operating principles: beam or deflection, dial indicator, clicker, and digital.
How do I know which torque wrench I need?
The bigger the drive and the longer the handle, the more torque they can deliver. Most home mechanics will find that a torque wrench with a 1/2-inch drive and at least an 18-inch handle is the best choice for lug nuts, cylinder heads, suspension bushings, and other likely uses.

What happens if you over torque?
Everyone who has ever worked with fasteners has accidentally messed one up at some point. One of the most damaging ways to do that is by over-tightening, or over torquing the fastener. This can result in stripping screws, snapping screw heads and damaging pre-tapped threading.
What happens if you don’t torque?
Insufficient torque
Alternatively, the engine’s vibrations can cause the bolt or nut to come undone, displacing the tensioner. This, in turn, will lead to incorrect belt tension and, eventually, to belt and/or engine damage.
What size torque wrench is best?
Most home mechanics will find that a torque wrench with a 1/2-inch drive and at least an 18-inch handle is the best choice for lug nuts, cylinder heads, suspension bushings, and other likely uses.
How accurate are click torque wrenches?
between 3 and 5%
The accuracy of clicker wrenches should be between 3 and 5%, depending upon the manufacturer. And as with any other tool under ISO 6789, they should be calibrated at a minimum of every 12 months.
How many times should you click a torque wrench?
One click is enough
When you’re tightening a bolt, one click is enough. Many users allow their wrenches to click more than once, but this means they’re applying added torque to the bolts. Use your tool in a smooth, steady fashion and let it click just once.
