HYDRAULIC COMPONENET REPAIR

HYDRAULIC COMPONENET REPAIR

At Janox, there is not a single part of the hydraulic system that we cannot build or repair. With our 50 years of experience, we can service it all – cylinders, pumps, HPUs, PLCs, and everything in between.

The hydraulic technicians, welders, and machinists at Janox bring their extensive experience to each project – no matter how large, or how small. We understand hydraulic system design and each component’s capabilities, and we know how to repair them to ensure maximum performance.


WE HAVE PRODUCT EXPERTISE IN EVERY ASPECT OF HYDRAULICS

When it comes to hydraulic component repair, our approach is rooted in thorough diagnostics, and precise execution and includes:
  • Hydraulic cylinders
  • Pelton turbine nozzles
  • Generator Brakes
  • Hydraulic power units (HPUs)
  • High-pressure oil injection systems (HPOIS)
  • Gear manufacturing
  • Gearbox re-builds
  • Machining, welding, and fabrication (CWB W47.1 and ASME BPVC)


Our custom-built test bench allows to ensure that all components leave our shop ready to face the demand of industry

While the range of component repairs and rebuilds is extensive, below are a few notable examples:

  • Mining components including CAT 7495
  • Hoist cooler
  • Hydraulic snubbers
  • Hydraulic pumps, hydraulic motors, manifolds and other standard components

One example of a Janox hydraulic component repair project was the complete disassembly, inspection, and re-build of generator brakes. This particular re-build required both machining the piston bore and installing stainless-steel sleeves with interference fit. Once we finished the repairs, we assembled each brake, tested them, and then painted them.
