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 Application
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.
A: We are the original manufacturer with more than 20,000sqm workshops, meanwhile a new 13,000sqm workshop is under construction.
A: If any customer wants a square drive hydraulic wrench, you’re kindly requested to provide necessary information as mentioned below:
