Product Name: Prestressed Bridge Tension Equipment Hydraulic Mono Strand Jack Model NO.: ZT-J005 Condition: New Certification: CS, CE Max Height: >400mm Power Source: Hydraulic Capacity (Load): 21-30T Structure: Hydraulic Jack Type: Hydraulic Jack Tension: 270 Kn Oil Pressure: 62MPa Weight: 24kg Tensile Stroke: 200mm Trademark: ZHonGTUO Transport Package: Wooden Box Specification: hydraulic Origin: China Product Description Mono Strand Pulling JackApplication:It is a multi-purpose prestressed tensioning device, which is easy to operate. Mainly used for single hole tensioning. It can also be used for porous pre-tightening, tensioning and troubleshooting, and can be applied to high-strength steel wire bundles and steel strands of various specifications.The front card through-heart hydraulic jack is suitable for single-hole tensioning, group-anchor tensioning, troubleshooting, anchoring, and tensioning.Structural features:A, the tension cylinder and the return cylinder are double sealed, which improves the sealing reliability. The small cylinder and the two cylinders, the small cylinder and the rear end cover, and the small cylinder and the tool ring are connected by a key to prevent rotation. They are sealed with Glüd or Sterling rings and are reliable in sealing.B. The two cylinders and the piston head are designed as a whole, avoiding the possibility of failure due to two-body welding or two-threaded connection. Increased processing difficulty, but improved reliability.C, wear ring, wear sleeve improved design, to avoid the possibility of assembly-type force pull-out, improve product reliability.D. All the important parts that are stressed are made of high-quality alloy structure or tool steel to improve hardness and strength.Advantages: small size, light weight, high efficiency, short reserved length.Technical Parameters:Rated tensile ForceKNThrough hole Diameter MMRated oil pressureMpaDimensionsMMTension cylinder areacmWeightkgTensile StrokeMMReturn hydraulic pressureMpa270<1862Mpa114x4854398.224200<10
