Durability under extreme loads and repeated cycles
Power That Moves Your Load
Custom hydraulic cylinders for mining machines
In mining applications, equipment must operate reliably under continuous cycles and harsh working conditions, including limited maintenance windows and 24/7 usage. Norrhydro design and manufacture high-performance hydraulic cylinders for underground and surface mining machines, built to withstand extreme loads, abrasive conditions, and continuous operation. Engineered for reliability in demanding environments, our robust solutions—especially for mining loaders—minimise downtime, extend service life, and keep your machines running when it matters most.
