Can the AK 850 work with luffing jib and Maxilift at the same time?
No. Schmidbauer have all the parts for the cranes luffing jib and maxilift system, but it can’t be rigged at the same time due to the way the crane is built. The reason is that the bracing for both the jacks and the derrick mast are located at the cranes A frame.There is only 1 set of bracing so you can have maxilift and luffing jib at the same time. This relates not only to the AK 850 but also to all of the AK 680 and AK 912 cranes. Therefore the setup that can be achieved with Kibri kits 10427, 10492, 10788 and 11104 is not prototypical. 10326, 10426 and 10438 are the only three ways the crane can be rigged up.
