Complete In-House Repair Solutions

When it comes to faulty hydraulic cylinder rams, we have you covered. From bent rods and damaged tubes, to re-sealing and pressure testing, no job is too big. We stock over 5000 seals and a range of metric and imperial chrome rod to cover most jobs.

Our machine tools allow us to precisely turn and mill replacement chrome rods, tubes, pistons, glands and eyes to suit every ram.

Tubes and eyes are welded in-house by our ISO9606 coded welders, and every job is pressure tested before it leaves our workshop.

Tailored Ram Manufacture.

Catering for one-off or batch production of single acting, displacement or double acting rams; we offer a complete design & manufacture solution tailored exactly to meet end user requirements. From initial sizing calculations to 3D modelling and BOM generation (if required), we carry the job through to machining, fabrication, testing and painting ready for dispatch. We will also work to customer drawings if provided.

Knowing the difficulties in sourcing non-obsolete replacement OEM rams with reasonable lead times, we can also offer a replication

Hydraulic Power Packs

We design and build hydraulic power packs to suit every application, whether, mobile or static, electrical or engine driven. From smaller flow rate units running 12 or 24vdc, up to larger 3 phase 20kw units capable of high flow rates and pressures.

Using cetop manifolds and directional control valves, complexity can range from single service units, up to several individual services with a range of logic and control options.

All power packs are assembled using quality components and tested before leaving our works. Paint options are also available.
