Concrete Prestressing Jacks Mono Strand Pulling Jacks

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.

Advantages:

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.

Checking methods:

(1) It is a relatively accurate method to calibrate the jack with the standard force juice (such as sensor, force ring, etc.) to be measured. And it is suitable for mobile units. It is recommended that the construction unit purchase sensors and a resistance strain gauge, and then make a self-made afterburner to verify the jack.
(2) Use the testing machine to check the jack. This method is a routine method used by many units.

(3) Two jacks on the item method; use a verified jack as the "standard" jack, and verify the jack by mutual jacking.

Application Fields:

When tensioning, the work is stable, the oil pressure is high, and the tension force is large. It is widely used in the prestressed construction of highway bridges, railway bridges, hydropower dams, and high-rise buildings.
