The mechanism of the wedge and chain block combines! A new method that changes bridge maintenance.
"Torque Up" is a jack system with a reduction gear that operates based on torque input. There is no risk of shock or sudden descent during jacking up, allowing for precise control of the lifting amount, and it is safe because the wedge does not retract even when the reaction force acts for a long time. Due to its safety, reliability, and high quality, it has garnered significant attention not only in civil engineering but also in rescue operations during disasters. 【Features】 ■ No hydraulic jack required ■ Capacity ranges from 75 tons to 1000 tons ■ Power source is a rechargeable driver (approximately 14V) ■ Height management for jacking up can be done in 0.1mm increments ■ Over-winding prevention operates beyond the reaction force, ensuring safety *For more details, please refer to the PDF document or feel free to contact us.

basic information
**Principle of Torque Up (Jack Up)** - Composed of a frame, wedges, gears, and an electric screwdriver. - The rotational force of the electric screwdriver is reduced by a variable speed gear, converting tensile force (horizontal force) into lifting force. - The frictional force generated between the lower wedge and the upper wedge is resolved through a sliding function. - The variable speed gear adopts the mechanism of a chain block. *For more details, please refer to the PDF materials or feel free to contact us.*
