Mining & Machine Building
First In Service builds heavy machine assemblies, structural frames and conveyor elements for mining and machine building, machined from hardened and wear-resistant steels for high-impact, abrasive service. Fabrication, machining and assembly run in one 18,000 m² Tallinn workshop with 160-tonne lifting capacity, inspected by VT, PT and MT.
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 ISO 3834-2 and EN 1090-2, and large rotating parts are turned to Ø 2,700 mm on our vertical lathe.
