1.Hydraulic cylinder hollow jack
Hydraulic jack, tensioning operation, suitable for various steel strand anchoring. Generally, the tension of the high-pressure oil pump needs to be matched, and the tension and power are returned through the tension of the oil pump.
2.Main application areas of post-tensioning hydraulic jacks
Building structure reinforcement
Building structure reinforcement: In the process of building structure reinforcement, post-tensioning prestressed hydraulic jacks can be used to 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, post-tensioned prestressed hydraulic jacks are used to increase the bearing capacity and stability of the foundation by applying prestressing force, thus avoiding problems such as foundation settlement and collapse.
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.
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.
