Product Questions & Answers (3)

Question by: Sherry M on Jul 4, 2025, 12:42 PM
Wondering if this cylinder is gonna be strong enough to pull some stuck pilings? We're talking about maybe 10 tons of resistance.
Answer by: Customer Support on Jul 6, 2025, 9:36 AM
For pulling pilings, this 12-ton cylinder should do the trick, giving you a little overhead. Just make sure your setup is solid and can handle the force.
Question by: Janet M on Mar 1, 2026, 8:24 PM
got a job pulling anchor bolts, is this RH121 the kind with the hole through the middle for that?
Answer by: Customer Support on Mar 3, 2026, 7:59 AM
For pulling and tensioning work, the RH121 is a center hole, single-acting cylinder made for jobs like anchor bolts, cables, and forcing screws. The through-hole diameter is 0.797 inch, and it is rated for 12 ton capacity.
Question by: Chad W on Mar 19, 2026, 6:59 AM
does this cylinder work for cable tensioning or is it mainly just a pushing tool
Answer by: Customer Support on Mar 20, 2026, 5:15 PM
Cable tensioning is actually one of the core uses it was built for. Pulling and tensioning cables, anchor bolts, and forcing screws are all listed applications. The center hole design is what makes that possible since it lets you feed a cable or bolt straight through the cylinder body. With 12 tons of capacity and a 0.797-inch hole diameter, it handles those jobs without needing any adapters or workarounds.
