YERLY J.M. SA

Our company, based in Domdidier (Switzerland), is specialized in maintenance and repair of all brands of cranes for twenty years.

Following wide considerations on the constraints caused by the jib obstruction and the large amount of wasted time due to interferences between several cranes, we decided to design the COBRA, largely inspired from harbour cranes. Ease of handiness and speed of operation were our aims, and the discovery of the mobile counterweight made possible the use of the harbour cranes concept on construction sites.
