Mining & Machine Building
Crusher frames, conveyor structures and large machined components in wear-resistant steel — up to 160 tonnes, 20 km from a deep-water port.
The replacement part is never the expensive part.
Mining equipment lives under shock loading, abrasion and duty cycles that no laboratory specification fully captures. When a crusher frame cracks or a conveyor structure fails, the cost is not the replacement component — it is the production hours lost while it is fabricated, shipped and installed. Which is why mining procurement values two things above price: structures built right the first time, and a supplier who can ship a 40-tonne weldment without a three-day permit negotiation.
Heavy structures and large machined parts, close to the ship.
We fabricate and machine crusher and mill components, conveyor structures, frames, housings and wear-exposed assemblies up to 35×7×7 metres and 160 tonnes, in wear-resistant and high-strength steels as well as stainless and specialty alloys. Welding is certified to EN 3834-2 and EN 1090-2, and large rotating parts are turned to Ø 2,700 mm on our vertical lathe.
