The working principle of the front clamp jack reflects the efficient integration of hydraulic and mechanical. The hydraulic oil enters the jack cylinder under the action of the oil pump, so that the piston gets the forward thrust. At the beginning of the clamp has a tight grip on the strand, as the piston moves forward, the strand is stretched, and the prestress is gradually established. During tensioning, the tension can be monitored and adjusted in real time through the pressure display and adjustment device. When the prestress value required by the design is reached, the pressure holding device maintains a constant pressure to ensure the uniform and stable prestress. Finally, through the oil return process, the piston moves backward and the clip releases the steel strand. This principle ensures that in the prestressing construction, such as the prestressing treatment of the floor slab of a high-rise building, the prestress can be accurately and reliably applied and the structural performance can be improved

Structural characteristics
A, Prestressing Mono jack tension cylinder and return cylinder are double sealed to improve the reliability of sealing. Prestressing Mono jack's small cylinder and two cylinders, small cylinder and back end cover and small cylinder and tool ring are all connected by a key to prevent rotation. Prestressing Mono jack are all sealed with Glay circle or Stirring, and the sealing is reliable.
B, Prestressing Mono jack two cylinder and piston head design as a whole form, to avoid the possibility of failure due to two body welding or two bodies to thread connection. It increases the difficulty of processing technology, but improves the reliability.
C, Prestressing Mono jack wear ring, wear sleeve improved design, to avoid the possibility of assembly stress out, improve product reliability.
D, Prestressing Mono jack all stressed important parts, have chosen high quality alloy structure or tool steel manufacturing, improve hardness, improve strength.
