Industry examples


The engine will not start without us.

The special tools for production lines, special tasks and maintenance are supplied by us to the automotive industry. Our tools reduce the expense of disassembly. In the event of a repair, the problem area can be penetrated directly with our tools without time-consuming disassembly and reassembly.


Trains would remain stationary without us.

Trains move millions of people and also ensures a prospering economy by means of its freight transport. We have built special tools to assist with maintenance and repairs. These tools save costs in reducing the fall out time and minimizing the workload. These tools which are specially made, guarantee the safety of millions of people.

Power plant

Without us, the turbines will not turn.

When confronted with elemental forces during use, material and construction are both physically and financially under enormous pressure.
The shortest turbine standstills can cost millions. A suitable tool only weighing a few kilograms can contribute to the avoidance of these costs, at a price which is a fraction of the expense of a single malfunction.
