Special tools - Manufacturing examples

Special stud driver
Challenge:
Our customer's requirement was a special screw-in chuck for work on his stud bolts. In order to work as effectively as possible, the tool was to be driven by a cordless screwdriver.  

Our solution:
Taking into account the defined length of the studs, we designed a tool with an E11.2 mount as the drive. On the output side, we took into account that the bolt is screwed in to the defined dimension.

Result:
The tool has been supporting the customer for some time now in the bolting work on the studs.
Special wrench for tube nuts
Challenge:
Our customer was faced with the challenge of having to tighten a special castle nut, which was not possible with a standard tool.

Our solution:
We manufactured a raw nut wrench in various sizes to meet the required specifications. A support on the side was also designed for stabilization.

Result:
Thanks to the wrench, the customer's processes could now be optimized to the maximum.
Parallel shaft gearbox

For complicated bolting cases with limited space, we have developed a flat gear for tightening and loosening bolted joints, so that disassembly of the components is no longer necessary. The product can be adapted to the bolting according to customer requirements.

Special flat gear with adapter

Our special flat gear with quick-change adapter is suitable for screw connections that are difficult to reach with a standard tool. The tool is available in various lengths and shapes and can be customized according to customer requirements.

Torque gauge Torquick MD-18

Our Torquick MD-18 torque gauge is especially suitable for closure torques in the beverage and canning industry. The Torquick is both adjustable and automatically releasable. In addition, the special tool is suitable for right-hand and left-hand operation and convinces with its low-wear permanent magnets.

Special cordless screwdriver

To increase the tightening torque of an electric screwdriver, we designed a special power gear and a special support. The product thus convinces with increased power, low weight and ergonomic operation.

Special assembly tool

Our special assembly system has slotted inserts and is especially suitable for cable glands due to the open ratchet system. The special tool is available in wrench sizes 15, 16, 19, 20, 25 and 30 and can be used with a torque wrench.

Special insert with pin

Counterholder for screw connections: Before and after comparison
Customer requirement
The customer's requirement was the development and construction of a counterholder for bolted connections in a chassis. The counterholder was to be supported by the bolt head opposite the bolt head.

Project procedure
Due to the different positions, we designed different versions of the counterholder. It had to be taken into account that the counter-support could be loosened easily and with an adjusting screw.
Special tools for the revision of wind turbine
Customer situation
Regular maintenance is indispensable for wind turbines. Maintenance includes, among other things, the time-consuming replacement of the fastening bolts.

Tool solution
Maintenance can now be carried out more easily thanks to a special loosening device for expansion bolts including electric drive and power gear. The designed special tool makes it possible to reduce the amount of work per bolt from approx. 30 minutes to approx. 5 minutes.

Industry examples

Automotive
industry

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.

Railroad
industry

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
technology

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.
