Long stroke hydraulic hollow jack need to be customized. The tensioning stroke of the hydraulic hollow jack is designed to be 200mm. If you need to lengthen or shorten it, you can contact us to customize a special stroke.

It is used with electric oil pump and intelligent tensioning equipment.

Product display

Compact structure, good sealing, light weight, small size, using high-quality materials and advanced technology production, the product is more durable. The long stroke hydraulic hollow jack can be used for various tensioning constructions with various accessories, and can also be used for tensioning and top-pressing construction of external cables and steel strands. The long stroke hydraulic hollow jacks of different sizes and specifications can be customized according to the different needs of customers to meet the different needs of customers.

Advantage

1. Safety valve protects against overload, double-acting for quick return and hollow plunger to allow both push and pull.

2. Increased processing technology difficulty, but improved reliability.

3. The improved design of the wear-resistant ring and wear-resistant sleeve avoids the possibility of the assembled type coming out under force and improves product reliability.

Technical parameter

The working sequence of tensioning construction: threading → installing anchors → installing jacks and tensioning equipment → tensioning, anchoring → removing jacks and tensioning equipment → grouting → beam storage.

Application

The long stroke hydraulic hollow jacks are widely used in prestressed tensioning construction projects such as highway bridges, railway bridges, hydropower dams, and high-rise buildings.
