Abstract
This paper aims to evaluate the benefits and disadvantages of applying a digital hydraulic concept to actuate a knuckle boom crane. The standard cylinders of the knuckle boom crane will be substituted with multi-chamber cylinders of comparable size. The performance of one of the multi-chamber cylinders will be compared with the standard differential cylinder. The standard cylinder will be actuated with a constant pressure supply, a proportional directional valve and a proportional controller. Control performance and energy consumption for the two configurations have been considered. It is concluded that more research is needed into the control strategies in order to improve robustness and performance.
