ZRDH-307: 30 TON 7" Stroke Double Acting Hollow Cylinder

Engineered for pulling, tensioning, and testing operations, the ZRDH-307 provides 30 tons of capacity paired with a 7" stroke. Its center-hole design accommodates cables, rods, and tooling directly through the body, while the double-acting hydraulic circuit delivers fast, controlled retraction under load. Collar threads, base mounting points, and standard 3/8" NPT quick-connect couplers allow straightforward integration into dedicated production or maintenance rigs.
