The K850, with a maximum hook height of almost 37 m and an extension length of 37.6 m, fulfils nearly all the demands required by roofers and carpenters of a high-performance crane. An extraordinarily big range of 31 m with a load of 500 kg makes day-to-day work easier in timber frame and hall construction, as it does in the flat roof sector. Driven by a separate economical diesel engine, the K850 consumes little fuel – that saves money and protects the environment.
