Product Description of Multi Wire Strand Jack for Concrete Prestressing

Double acting hollow hydraulic cylinder is connected with all the design features of single acting hydraulic cylinder and the design superiority of a double-acting hydraulic cylinder, increases its operation and working speed, especially, since it can make the best of its hydraulic force in the long-stroke engineering. 
This type of hydraulic cylinder has a central piston, it is widely used for nuclear power plants, tunnel engineering, foundation, and other similar projects. And it can be connected with prestressed craft, it is also used for post-tension prestressed bridge projects.

Applications of Multi Wire Strand Jack for Concrete Prestressing

Our hydraulic cylinders have been widely used in industrial fields, such as steel plants, the cement industry, chemical and refineries, bridges, railways, highways, hydropower stations, ship repair, building, construction, and maintenance.

Features  of Multi Wire Strand Jack for Concrete Prestressing

The structure of the through-core jack is relatively simple, consisting of an upper cover plate, a folding ejector rod, a spring, a movable handle, a tie rod, a pressure plate, and a metal gasket. Compared with ordinary jacks, its main feature is that the ejector rod can slide in both directions. This is because there is a special threaded hole on the ejector rod that can be connected to the pull rod, making it easy to move the ejector rod upward or downward.

A. It is very durable to use.
B. Easy to operate and control.
C. It can be used for lifting heavy machines, bridge projects, hydraulic engineering, harbor construction, and other equipment.
D. It has a large output, lightweight, and remote control.
E. It can match our high-pressure oil pump.
F.  It can reach jack, push, pull, and extrusion kinds of working.
 

Working Principle

The through-core jack is a double-acting jack that uses dual hydraulic cylinders to tension prestressed tendons and press anchors. Through-the-core jacks are suitable for tensioning belts
Its working principle is: when tensioning the prestressed tendons, the oil nozzle of the tensioning cylinder enters and the oil nozzle of the pressing cylinder returns oil. The pressing cylinder, connecting sleeve, and support sleeve are integrated into one and move to the right to resist the anchor ring; the tensioning cylinder, end The cover nut and plug are integrated with the core sleeve to drive the tool anchor to the left to stretch the prestressed tendon; when pressing the anchor, under the condition of keeping the tension stable, oil is fed into the oil nozzle of the pressing cylinder, and the piston and protective sleeve are pressed It is integrated with the jacking head and moves to the right to force the clip into the anchor ring; at this time, the oil nozzle of the tensioning cylinder returns oil, the oil nozzle of the jacking cylinder feeds oil, and the tensioning cylinder hydraulic returns. Finally, the oil nozzles of the tensioning cylinder and the pressing cylinder return oil at the same time, and the pressing piston returns to its original position under the action of the spring force.
For large-span structures and long steel wire bundles with large extensions, it is appropriate to use through-type jacks.
