General product description

Test rig and mountings for a long life testing of locks, latches, and emergency exit devices. Various lock systems are tested for different classifications in a durability test.

This test rig consists of a stable screwed frame and two test doors, which are mounted axial and radial bearings to ensure rigidity according to the standard. In addition, we deliver test weights meeting the standard and a closing device with deflection roller and the required weights.

Another component of the DDSB module is the control unit. This control unit operates the pressure and the durability function. It is composed of a mobile rack with a built in TFT screen and a configured PC.
