Company History


The Lang + Lang company was founded over 85 years ago as a retailer of technical industrial goods, and since the end of the eighties has been engaged in challenging tasks in the areas of technical documentation and instruction.

Through the use of current software technology, especially in the areas of 3D CAD representation, and the use of web-based technologies, high technical quality is combined with cost-reduced documentation methods. In addition to purely paper documentation, more and more purely computer-aided solutions, with integrated 3D CAD representation and simulation, are being used.

These technical options greatly simplify the transfer of knowledge between the product manufacturer and the user, with better accessibility.

Comprehensible technical documentation is an important characteristic of a product today, especially for technically complex industrial goods that are used in series production. Missing technical information can cause a line to shut down, thus incurring extensive costs.

Potential hazards can be decisively reduced by good, accessible technical instructions.

Technical expertise that allows the product and its functionality to be properly understood is thus the basic prerequisite for safe CE labeling with a risk analysis , in order to implement CE conformity in your products.

We have consulted for well-known companies for two decades, and provide innovative solutions.

Further information and examples of our technical capabilities are available under the "Technical References" menu item, in the left task bar.
