Product Overview
The Holmatro HHJ 30 S 15 is a professional heavy-duty steel hollow-plunger hydraulic cylinder engineered for pushing, pulling, tensioning, and lifting applications in foundation engineering and heavy industrial maintenance. Manufactured by Holmatro in the Netherlands, this single-acting cylinder features high hydraulic efficiency with an integrated spring-return system for smooth automatic piston retraction.
Designed with a central hollow bore, the HHJ 30 S 15 permits cables, tie-rods, and threaded anchors to pass directly through the cylinder body, enabling effective tensioning operations up to a maximum working pressure of 720 bar (72 MPa). Equipped with a high-flow A118 female coupler and a hollow saddle, it delivers a nominal capacity of 30 tons (293.7 kN) for specialized geotechnical and structural works.
Key Applications
- Tie-back anchor, cable, and threaded rod tensioning in geotechnical and foundation engineering.
