Bellows Test Machine
The Bellows Test Machine consists of a mechanism where the final load tests of bellows used in heavy commercial vehicles such as dump trucks and tractor-trailers are performed before they are mounted on the vehicles.
The most important aspects of these machines are: sending a stable test graph from the PC to the test unit and having the servo apply the graph exactly to the unit, and energizing the correct pressure valves at the right moments of the graph.
