■ Description

YDC500DY-250A PT Multi strand tension hydraulic jack is a prestressed automatic tensioning equipment with integral top pressing device. It adopts the structure form of core type double oil circuit, equipped with integral top pressure device and automatic tool anchor plate.

When the pc strand is tensioned, the wedges is pushed into the anchor hole through the top pressure piston without releasing the tension. Thus, it can reduce the shrinkage when releasing the tension of the strand, obtain reliable anchoring performance, and can be widely used in post-tensioning method Prestressed concrete structures, Bridges and other projects.

■ Application

1. Bridges: Segmental bridge girder post-tensioning

2. High-Rise Buildings: Flat slab & beam post-tensioning

3. Parking Garages: Long-span slab system

4. Railway & Subway: Track bed & tunnel lining

5. Hydropower: Dam & water conservancy structures

6. Mining: Rock anchorage & cable tensioning

■ Features

1. Productivity very high: Multiple strands at once

2. Labor cost: Lower on large projects

3. Uniformity: Excellent stress distribution

4. Portability: Bulky, heavy

5. Best For: Bridges, high-rises, parking garages, large infrastructure
