PTE Hydraulics are an Australian company and they manufacture these rams for OEM fitting to Sandvik tunnel machines used in mining.

We have 16 of these new unused - storage soiled - in stock and this might be handy in case you have a project or installation where you need multiple sets of identical rams. Auction is for one unit but winner can select any number from remaining stock.

Some are discoloured from storage but all are sealed and stored in closed position so all the working parts are untouched.

All the relevant specs are in the photos but basically:

Overall closed length C-C 920mm Overall open length C-C 1520mm Outer diameter of cylinder 100mm Ram body length 790mm Cylinder internal Diameter 90mm Ram Stroke 600mm Rod diameter 44mm Mounting pins 25mm Ports at 0 degrees

Maximum working pressure is 3000psi or 210Bar
