Mining & machine building
First In Service builds heavy machine assemblies, structural frames and conveyor elements for mining and machine building, fabricated and 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, and welds are inspected by VT, PT, MT, UT and RT.
Key takeaways
- Structures: crusher and mill frames, conveyor elements and support structures.
- Machined parts: rings, flanges, housings, shafts and bearing seats.
- Assemblies: mechanical assembly with FAT where the scope requires it.
- Materials: abrasion-resistant and high-strength steels, plus carbon steel, stainless, duplex and super duplex.
- Logistics: Muuga Harbour 20 km and Paldiski Port 60 km by heavy-haul road; ro-ro shipping up to 160 tonnes.
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 real cost is the production lost while a replacement is fabricated, shipped and installed. That is why mining buyers value two things above price: structures built right 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 speciality 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.

Questions mining & machine building buyers ask
What mining equipment components does First In Service manufacture?
Crusher and mill structural components, conveyor elements, frames, housings, wear-exposed structures and large machined parts up to 35 × 7 × 7 metres and 160 tonnes.
Do you work with wear-resistant steels?
Wear-resistant and high-strength steels are fabricated and machined alongside carbon steel, stainless, duplex and speciality alloys.
Can you machine large rings, flanges and housings?
Vertical turning reaches Ø 2,700 mm and 1,900 mm in height on the SC27 lathe. Longer parts up to 13,000 mm long and 4,500 mm high are milled and bored on the FERMAT boring mills.
How are oversized mining structures transported?
Our Tallinn facility is 20 km from Muuga Harbour, with direct heavy-haul road access and no urban restrictions. Ro-ro shipping is available for components up to 160 tonnes.
What documentation ships with mining components?
EN 10204 3.1 material certificates (3.2 on request), dimensional inspection reports, weld documentation and NDT reports where scope requires.
