Prestressed Post Tension Hydraulic Mono Strand Stressing Jack For Bridge

product description

The front snap jack is a multi-purpose prestressed tensioning device that is easy to operate. Mainly used for single hole tensioning. It can also be used for porous pretension, tension and obstacle removal, and it can be applied to high-strength steel wire bundles and steel strands of various specifications and sizes.

Technical Parameter

Product Features

1. Mono strand jack is mainly used for single-hole tensioning. It can also be used for porous preloading, tensioning, and troubleshooting, and can be applied to high-strength steel wire bundles and steel strands of various sizes.

2. Installation and construction are very convenient: no need to rotate the arbitrarily installed working anchor; no need to rotate the radial direction of the jac; it is easier and faster to install the tool anchor plate and tool clamp piece than the original post-card type.

3. The limit plate, tool anchor and tension jack are separated and independent.

4. Better stability: the conventional post-card tensioning jack for a 3-point piston guide, this series of tensioning jacks for a 4-point piston guide; overcome the 3-point guide eccentric tensioning force often produces the phenomenon of pulling the cylinder scrap jack.

5. It overcomes the shortcomings of cumbersome and inconvenient installation of the overall front card tensioning jack at home and abroad.

Precautions

1. The jack is connected to the oil pump through the high-pressure oil pipe, and the electrician connects the oil pump to the power supply through the power cord.

2. Turn on the oil pump and run it no less than 3 times. If there is crawling, it can be increased to 6 times. If there is crawling again, stop the pump for inspection and analyze the reason.

3. Before the calibration of the jack and the oil pump system and the implementation of tensioning, the jack must be run dry. Calibration or tension work can only be started after everything is normal.

4. All those who enter the site where the jack is used should do "clear the site at both ends of the jack when the oil pump sounds." On the one hand, avoid stretching and slipping wires to hurt people, and on the other hand, avoid misoperation of jack parts flying out and hurting people.

5. When the oil pump is turned on, the pump operator is not allowed to leave. When tensioning, pay attention to the specified value of the oil gauge. On the return trip, pay attention to the rapid pressure increase of the oil gauge. The boost pressure should not be greater than the specified return pressure.
