• With continuous central bore
Particularly suitable when high tensile forces have to be applied using threaded spindles.
• Many possible uses
Ideal for pretensioning tie rods, pressing bearings in/out, extracting pipes, pulling and moving heavy constructions.
Further hollow piston cylinders up to 140 t, also double-acting with hydraulic retraction, are available.
