Hydraulic Cylinder Hollow Jack 100 Ton 250 Ton 300 Ton 500 Ton Post Tension Hollow Ram Jacks

1.Hydraulic Cylinder Hollow Jack

Hydraulic pressure jack, tensioning operation, suitable for various steel strand anchoring. It generally needs to match the tension of the high-pressure oil pump, and the tension and power are returned by the tension of the oil pump.

2.Main application areas of post-tensioned hydraulic jacks
Building structure reinforcement: In the process of building structure reinforcement, the use of post-tensioned prestressed hydraulic jacks can improve the load-bearing capacity and seismic performance of the concrete structure by applying prestress. pressure.
Bridge construction: In bridge construction, the use of post-tensioned prestressed hydraulic jacks can improve the load-bearing capacity and seismic performance of the bridge, while reducing the bridge's dead weight and extending its service life.
Tunnel construction: In tunnel construction, the use of post-tensioned prestressed hydraulic jacks can improve the stability and load-bearing capacity of the tunnel while reducing deformation and settlement.
Foundation treatment: In foundation treatment, the use of post-tensioned prestressed hydraulic jacks can improve the bearing capacity and stability of the foundation by applying prestressing force, thereby avoiding problems such as foundation settlement and collapse.

3.working principle
The cylinder, head cover (adjusting nut), end cover (compression ring), front sealing plate, and rear sealing plate are connected to the cross core socket to form a "immovable body", and the piston of the jack is a "moving body". When the hydraulic pressure When the oil pushes the "moving body" to the right, it begins to tighten; when the oil pushes the "moving body" to the left, that is, the piston returns after being stretched.

How to choose the right hydraulic jack?
1. If large-capacity work and piston return stroke are required, a large-tonnage double-acting hydraulic jack (50-2000 tons) can be selected.

2. When it is necessary to pass through prestressed steel strands, steel wires or anchor bolts (50-2000 tons),
Optional double-acting hollow jack
3. If you want to install a jack on some working platforms, you need a flange hydraulic jack (10-630 tons).
4. Single-acting hydraulic jacks are used for work with smaller tonnage and stroke (10-100 tons).
5. When matched with special tools for threading cables or pulling rods, a single-acting hydraulic hollow jack (12-100 tons) can be selected.
6. The single-acting hydraulic jack with locking nut can be used at long-term pressure-maintaining work sites (55-200 tons).
7. Ultra-thin hydraulic jack is suitable for narrow working spaces (10-200 tons).
8. The electric oil pump is matched with various hydraulic jacks, with double-acting and single-acting options available.
9. The hydraulic hand pump can also be used with a hydraulic jack.

Hydraulic jack: large tonnage jack 65-600 tons; bridge hollow steel strand jack.
1. The main components of the jack are made of high-strength steel, which has the characteristics of compact structure, light weight and small size.
2. The axial length is short and the steel wire tension is short, which can save steel.
3. Flexible lifting and lowering, durable, simple operation and convenient maintenance.
