China Post Tension Stressing Jacks Manufacturers ...

Products Description

If you want to learn more, please visit our website Ruiyi.

By stressing prestressing strands or wires after multi strand post tension jack ensures that equal tension is applied. It allows measurements of both the prestressing force and elongation. 

For the whole prestressing pocess, post tension stressing jack is matched with tool anchorage and wedge to stretch PC strand. It is powered by pump, calibrated gauge readings indicate the tension force applied to tendon. based on different model, tension force is from 70tons to 650tons. The jacks is linked with two ends of tendons and ensure two sides are fully stretched. if only one side is stretched, the other side should be fixed, we call it dead end such as swage end which is formed by swaging socket and spring.

Post tension tendon loss includes: duct friction loss, anchor loss, elastic compression loss, steel stress relaxation loss, and concrete contraction loss. The first three occurred in the tension stage, called instanta loss, and the latter two were long -term losses. In addition, anchor mouth friction loss should be included.

Advantage of main components

Cylinder

1. 40Cr forging material is adopted, resistant to ultra-high pressure and not easy to deformation.

2. Oil cylinder inner hole is olled to improve surface strength and hardness, improve surface wear resistance and extend service life.

3. The oil cyinder and end cover are connected by internal thread, with good overall force and high safety factor.

Plunger

The piston is processed by integral forging parts, with superior mechanical performance and durable service.

Steering method

The guide part adopts surfacing copper technology, the guide length of piston ring is longer, the guide performance is good, the ability of resisting partial load is strong, it has the advantages of wearresisting, pressure-resisting, corrosion-resisting, etc, and it is easy to disassemble and assemble, and spare parts can bereplaced without special tools.

Sealability

in the dynamic seal using green ring instead of 0-ing, green ring use pressure up to 80Mpa, the temperature range of -60-+200C,using green ring seal effect is better, more reliable.

Customized products

The first and second pictures are 500tons stressing jack, stroke is 200mm, with one 180mm extension cylinder, hanging hook, one tooling anchor and limiting plate etc. this jack is for a Singapore client, all the jack's design and dimension is based on client's drawing and requirments. This client was very satisfied with everything, and placed order again.

The third picture is 250tons mono strand jack with 500mm stroke, it was for a Guam client. The fourth picture is a open and close anchor, also for this Guam client. We have built long term relationship with this client.
