Heavy-Duty

WHEN SIZE AND PERFORMANCE ARE CRUCIAL

HEAVY-DUTY GEARS FOR LARGE AND HEAVY APPLICATIONS


As the name suggests, our Heavy-Duty products are large gears for demanding tasks. We turn, tooth, harden and surface treat gears up to 8 m in diameter.

These gears are primarily used in the wind turbine industry, but mining, shipbuilding and cement production also benefit from our expertise in this special area. They are used in MAN marine engines and Vestas and Siemens wind turbines.

Thanks to both conventional and state-of-the-art CNC machinery, we can supply large, top quality cylindrical gears. With our own hardening plant, we are also able to offer some of the best quality and delivery times in Europe.

WHEN QUALITY IS CRUCIAL

Quality can be measured, tested and documented in many ways. We offer quality assurance at precisely the level customers need. But for us, the biggest test of quality is customer satisfaction.

DURABILITY

Gears that withstand the most demanding situations.

PRECISION

Gears that meet the customer’s specific needs exactly.

QUALITY

Gears with documented quality in each process step.

MHI Vestas

Developing the world's largest wind turbine

The development of a new yaw rim system would also result in significant changes in relation to the existing design of other wind turbines in Vestas general product program.
