Find the Right Equipment by Working Condition

The S series heavy-duty electric torque wrench is designed for tightening and removing large bolts in demanding industrial applications. It is suitable for railway maintenance, tower cranes, vehicle tires, bridge engineering, steel structure installation, construction machinery repair and heavy equipment maintenance. Equipped with a powerful copper-core motor, the tool delivers high torque output for both standard bolts and high-strength bolts. The series includes S2000 and S3500 models, which can be selected according to bolt size, torque requirement and working conditions.

The cooling circulation water tank is an auxiliary device designed to provide circulating cooling water for pipe welding equipment and mechanical equipment. It is suitable for outdoor construction sites without fixed water supply, unstable water supply conditions, or applications that require continuous cooling. The unit can supply stable cooling water for plastic pipe butt fusion welding machines, electrofusion welding machines, arc cutting machines, pipe bending machines and other water-cooled equipment.

The electric shear wrench is a dedicated electric fastening tool for torsional shear type high-strength bolts. It is widely used in steel structure installation, bridge construction, factory buildings, tower structures, railway engineering and large equipment installation. The tool tightens the bolt electrically and automatically shears off the spline end when the required fastening condition is reached, making it easier to confirm completion on site. The series includes H24, SH24 and SH30 models, which can be selected according to bolt size, maximum torque and job-site working intensity.
