Multi PC Strand Electric Hydraulic Jack Bridge Building Hydraulic Jack For Prestressing

Working Principle of Muti-Strands Post Tension Jack

When the prestressed tendons are stretched, the oil nozzle of the tension cylinder enters the oil, and the oil nozzle of the top pressure cylinder returns oil, and the top pressure cylinder, the connecting sleeve, and the support sleeve are connected together and moved to the right to support the anchor ring; the tension cylinder, end cover nut, and The plug and the through-core sleeve are connected together to drive the tool anchor to move left and stretch the prestressed rib. When the anchor is pressed and the tension is kept stable, the oil nozzle of the pressing cylinder will enter the oil, press the piston, the protective sleeve, and the pressing force. 【WhatsApp/WeChat/Phone/Skype】+86 13201801998

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

The prestressed feed-through dry jack is one of the general series hydraulic feed-through dry jacks in the prestressed anchorage system. Equipped with corresponding limit plates, tool anchors, and other accessories according to user needs. It can be used for tensioning of XM, XYM, QM, OVM, and other series of anchor systems. With the corresponding accessories, it can also be used for jacking, weightlifting, and traction. This product adopts a new type of combined sealing ring, wear-resistant guide ring, polyurethane dust ring, etc. The strict test and long-term use of the project show that this product has the characteristics of good performance, durability, convenient use, maintenance, etc., and is very popular among users.

Routine maintenance of Muti-Strands Post-Tension Jack

1. Maintaining and maintaining the tension jack as required can ensure the performance of the tension jack, prolong the service life of the jack, complete the construction plan on time, and improve work efficiency, which is of positive significance.
2. The new or long-installed jacks have more air in the cylinders, and the pistons may jump slightly when starting to use. The jacks can be reciprocated 2 to 3 times with no load to remove the air in the inner cavity.

3. The muti-strands tension jack should be made of good mineral oil, which does not contain water and other mixtures, and does not decompose or deteriorate under normal temperatures. The oil should be kept strictly clean, often finely filtered, and replaced regularly
4. When the tension jack joint is connected with the oil pipe and the jack, the joint part should be cleaned and wiped clean to prevent sand and dust from entering the tension jack.
5. The exposed worksheet of the tension jack should be wiped frequently and kept clean. After the work is completed, the piston should be returned to the end. When it is idle, it should be covered with dustproof and placed indoors. When it is temporarily placed outdoors, it should be dustproof, rainproof, and sunscreen.
