Complete bicycle test machine

BMD complete bicycle drum testing machine. The machine is constructed in accordance to the current EN norms and additionally the German “DIN+” standard.

The machine tests a fully loaded bicycle according to standard.  It includes all the weights and suspension.  In the automated system the sequence can be set either accordingly to the EN standards or according to your own desired sequence.

For each sequence there are three different height points in the drums available.  The drums (front and rear) are controlled independently.  This means they can be set to be in sequence or at random.  They will drive the wheels in a random sequence and the set blocks will load the bicycle accordingly.

In the testing database there are 32 separate waypoints available, additionally a time span can be set for each independent waypoint or independent test distance.

The bicycle is secured in the protective frame and moved over the drums.  The bicycle is fully loaded next to the machine and moved with an electrical overhead crane in to the machine; there it is strapped and fixed accordingly.  Additionally the safety switches to the different parts are connected to ensure shut down if there is a material failure.  The outside frame is constructed from aluminum with Lexan (crash proof) windows for security.
