YDC500DY-250A PT Prestressed post tension multi-strand hydraulic jack
YDC500DY-250A PT Prestressed post tension multi-strand hydraulic jack is a specialized hydraulic tool used to simultaneously tension multiple high-strength steel strands in post-tensioned concrete structures (bridges, buildings, railways, etc.). Unlike mono-strand jacks (which tension one strand at a time), multi-strand jacks grip and stress all strands in a tendon bundle in a single operation.

Description
YDC500DY-250A PT Prestressed post tension multi-strand hydraulic jack is a specialized hydraulic jack designed for the automatic post-tensioning of PC strands. Featuring an advanced core-type double-oil circuit, this unit integrates a built-in top-pressing device and an automatic tool-anchor plate.
A key advantage of its design is the ability to drive wedges into the anchor hole via the top-pressure piston while maintaining full tension. This mechanism effectively minimizes strand shrinkage during release, ensuring highly reliable anchoring performance. It is ideally suited for a wide range of applications, including prestressed concrete structures and bridge construction projects.

Application
When the jacks' hydraulic matched the prestressed anchorage and strands. It is widely used in the construction of bridges and buildings, railways and subways, water conservancy and hydropower engineering. In certain circumstances, it can be used in the working of pushing, jacking and transforming and so on.
Application of prestressed post-tension hydraulic jack:
1. It is widely used for the construction of bridges and buildings, railways and subways, water conservancy and hydropower engineering, matched with prestressed anchorage and strands.
2. It is suitable for stressing mono strands or multi strands, the specifications are Φ15.24 andΦ12.7.
3. In certain circumstances, it can be used in the working of pushing, jacking and transforming and so on.
4. Easy to use with a reasonable price.
5. Jack is used for the prestressing workshop.
Application scenarios of the multi-strand hydraulic jack:
1. Bridges & viaducts (the most common heavy-duty use)
2. High-rise buildings (floor slabs, transfer beams)
3. Railway & subway tunnels
4. Water conservancy & hydropower dams
5. Coal mine support structures
