A Hole Straight Through the Ram
Center-hole (hollow plunger) cylinders have an opening running through the middle of the ram, so you can pass a cable, tendon, rod or threaded bar right through and pull on it. That single feature unlocks a whole category of tensioning, testing and pulling jobs a solid cylinder simply can't do.
Built for Tensioning and Pulling
Post-tensioning cable, tensioning tie-rods, load-testing anchors and bolts, cable pulling, and maintenance pulls are all natural fits for a hollow cylinder. Available in single- and double-acting versions to match how much control you need on the return stroke.
Where Center-Hole Cylinders Shine
- Post-tension and cable tensioning
- Anchor, bolt and material load testing
- Rod and cable pulling
- Any job that needs to pull through the center
