Monostrand Jack Bridge Erecting Machine Low Relaxation Prestressed Concrete Strand
Description of Hydraulic Mono Strand Jack
Hydraulic Mono Jack is multi-purpose prestressed tension equipment, easy to operate. Mainly used for single-hole tension. It can also be used for porous pretension, tension, and barrier removal, and can be applied to a variety of specifications and sizes of high-strength steel wire bundles and strands. Jack is one of the indispensable tools in tension anchorage construction of prestressed engineering. No jack is a panacea. The jack structure, structure size, and tension tonnage limit its scope of use. The front jack is small in size, light in weight, and high in efficiency.

Components of Mono Jack
Advantages of Hydraulic Mono Strand Jack
1. During the tensioning process, the jack can automatically clamp the prestressed tendons and retract the anchor, thereby reducing labor intensity and improving working speed.
2. The jack is designed with accessories with various functions, which can be selected according to needs during work.
3. The jack will not spin when working, which avoids the excessive elongation of the steel strand due to rotation.
Mainly used for single-hole tensioning. It can also be used for multi-hole preloading, tensioning, and troubleshooting, and can be applied to high-strength steel wire bundles and steel strands of various sizes.
4. The front card jack is small in size and light in weight. The important thing is that the reserved length is about 260mm short due to the kilocalorie-type steel strand. Especially suitable for high-altitude or small space operations.
