Advantages of Multi PC Strand Electric Hydraulic Jack​:

1. Mainly used for overall tensioning of group anchors.

2. The Multi PC Strand Jack is easy to operate, reliable in performance, and saves steel strands to the greatest extent.

3. The Multi PC Strand Jack is mainly used in the construction of bridges and other projects in conjunction with products such as prestressed anchors and tensioning equipment.

Features of Muti-Strands Post-Tension Jack:

1. The muti-strands post-tension jack is a special tensioning jack used for tensioning steel strands and other prestressed tendons. Generally, it needs to be used in conjunction with the tensioning oil pump. The power for tensioning and returning to the top is provided by the high-pressure oil of the tensioning oil pump. According to the different structures, it is divided into front card tensioning jack and through-center tensioning jack.
2. The tensioning jack has a compact structure, stable operation during tensioning, high oil pressure, large tensioning force, large-span structure, long wire bundles, etc. Tension construction projects such as hydropower dams and high-rise buildings.

Installation of Multi PC Strands Jacks and Anchors

(1) The steel strand is inserted into the reserved corridor of the structure, and the exposed length of the wire bundle at the tension end is required to be 200-250mm longer than the working length of the jack. The steel strand must be cut with a thin film grinder and must not be scattered or "hairy", so as to avoid difficulty in perforation.
(2) Put on the end of the wire bundle of the working anchor plate, push it to the anchor plate, and fix it with the stop.
(3) Install the working anchor clips: Before installing the clips, use a steel ring to tie each clip together, then push it into the taper hole of the anchor plate along the steel strand, and push it by hand until it does not move.
(4) Install the limit plate: The limit plate is designed according to the working anchor plate and matched with the holes of the anchor plate.
(5) Install the jack: first, tie the end of the steel strand bundle with iron wire pins, then the jack can be hoisted up and put on the steel bundle, and the support port of the front end cover of the jack is placed on the outside of the limit plate. At this time, the jack can be aligned coaxially.
(6) Install the tool anchor on the bearing stop at the end of the piston.
