Description

Engineered for specialized lifting and tensioning tasks, this hydraulic hollow plunger jack features a center-hole design that allows cables, threaded rods, and puller bolts to pass straight through the center of the ram. This unique configuration enables the tool to perform both pushing and pulling operations, making it ideal for tensioning anchor bolts, pulling stubborn pins, and pre-stressing structural elements. Constructed from high-strength forged alloy steel with precision seals, it withstands extreme hydraulic pressures while ensuring smooth, reliable stroke movement. Equipped with standard high-pressure quick couplers, it integrates seamlessly with manual or motorized hydraulic pumps. This dependable tool stands as a vital asset for civil engineering, bridge construction, and heavy machinery maintenance.

Frequently Asked Questions
1
What is the main design feature that distinguishes a hollow plunger jack from standard jacks?

It features a center-hole or hollow piston that allows rods, cables, or bolts to pass directly through the middle of the cylinder.

2
Can a hollow plunger jack be used for both pushing and pulling tasks?

Yes, by passing a threaded rod or cable through the center hole, it can be configured to pull components or apply linear tension.

3
What types of hydraulic pumps are compatible with these jacks?

They can be operated using standard manual hydraulic hand pumps or electric-driven power packs rated up to the required 700 bar operating pressure.

4
What materials are used to construct the cylinder body and plunger?

They are forged from high-tensile alloy steel with heat-treated bearing surfaces to handle immense compressive and tensile loads safely.

5
How does the plunger return to its starting position after operation?

Most standard models use an internal heavy-duty return spring, while larger versions may utilize a double-acting hydraulic return system.
