Our high-quality hydraulic torque wrenches are sold worldwide through a well-developed and fast global distribution network.
MXTD Series – Square Drive Hydraulic Wrench
MXTD series is the most classic hydraulic wrench, suitable for almost all specifications of bolts and various working conditions. Its maximum torque can reach 160000Nm.
Coaxial Square Drive Hydraulic Wrench
AXT series wrench is made of titanium alloy. The longitudinal dimension of the front reaction arm is small, and the reaction arm is coaxial with the square drive, which is highly adaptable.
BXTD Series Square Drive Hydraulic Torque Wrench
BXTD series wrench adopts precision small ratchet design, no non-return structure, and will not be locked due to the twisting of the bolt. It has few transmission parts and simple structure.
The square drive hydraulic torque wrench is one kind of hydraulic torque wrenches. Its drive shaft will drive the impact socket to achieve the pre-tightening of the nut, and is often used to tighten and remove bolts larger than one inch. Within a reasonable torque range, it can be matched with different high-strength sockets to act on bolts of different specifications. The square-drive hydraulic wrench is a general-purpose hydraulic wrench with a wider range of applications than the low profile hydraulic torque wrench.
TorcStark is a professional manufacturer of square-drive torque wrenches. We have full range of square-drive wrenches. All products are made of aluminum-titanium alloy and high-strength alloy steel. The one-piece fuselage can fully enhance the strength and toughness of the fuselage. It has longer service life, higher hardness and lower weight, and one power head can match a variety of working heads.
360°×180° rotating tubing joints are adopted, therefore no restrictions on operation space. Trigger-style lock, easy to press, you can freely set the 360° fine-tuning reaction arm on a solid fulcrum. There is no counteracting pawl to avoid tool jamming. Each stroke rotates 27°, and the speed is fast. Using precision ratchet, the accuracy is as high as ±3%. The small nose radius makes it easy to operate in a narrow space. Surface anti-corrosion treatment, suitable for use in harsh environments.
TorcSkark hydraulic square drive torque wrenches are widely used in electric power (nuclear power, wind power, hydropower, and thermal power), shipbuilding, metallurgy, transportation, cement, construction, aviation and other fields. We have won more and more customers with amazing product quality and cheap prices (TorcSkark is a manufacturer of square drive spanner. That avoids the dealers’ commissions to ensure your best price and highest profit.)

Square Drive Torque Wrench Applications
Where Are Hydraulic Torque Wrenches Mainly Used In Wind Power?
Hydraulic wrenches are often used for hoisting and maintenance in the wind power industry. Because of the special structure of the wind turbine, the tower, nacelle, hub and blades are all connected by flange bolts, and the number is large. The frequency of use of hydraulic spanner is high, and the equipment is labor intensive. The progress of the hoisting work and the stability and safety of the equipment are improved. Specifically, wind power hydraulic torque wrenches are commonly used in anchor bolts, blades to bearings, bearings to hubs, yaw drives, yaw bearings to foundation plates, yaw bearings to towers, main bearings to brackets, gearbox bases , Tower flange, shrink disk, hub adapter, main bearing bracket, variable pitch bearing to hub, variable pitch drive, variable pitch bearing to blade, disc and other places installation and maintenance.
Which Equipment Can Hydraulic Spanner Be Used In The Petrochemical Industry?
- The pipe box and inlet and outlet flanges of the light deoiling heater in the propane workshop are the most common operating conditions for hydraulic torque wrenches.
- The lower outlet flange of the hydrogenation unit. In this case, the quality of the hydraulic torque tools must be paid attention to. The problem of gas leakage occurs every year.
- Feedwater preheater for catalytic device
- Medium pressure steam pipeline
- Asphalt flash tank feed heater for propane plant
- 18m platform oil and gas shut-off valve and main valve flange
- Catalytic workshop reaction oil and gas DN900 pipeline flange
- Medium pressure steam valve in power workshop
- The lower flange of the quenched air in the olefin plant
- The safety valve for boiler drum in power workshop
With the rapid development of China’s construction machinery industry, the previous traditional construction operations have gradually been replaced by advanced technologies. For example, in the past, large bolts on construction machinery generally used jackhammers, large manual wrenches, or pneumatic wrenches.
However, because these traditional wrenches are not as large as hydraulic torque wrenches with large torque and accuracy, many construction machinery manufacturers are using hydraulic wrenches. . Hydraulic wrenches play an important role in the production and installation of hydraulic crushers, shield machines, grinders, excavators and other equipment, as well as in after-sales maintenance.
Steel plants and smelters have strict performance requirements for the tools used under extreme conditions, requiring tools that can withstand severe heat, dirt, and continuous work. Due to its reliability, durability and powerful functions, hydrolic wrenches can easily handle the toughest jobs and adapt to the harshest environments.
