Abstract (en)
[origin: EP0985629A1] The crane has a hydraulically actuated jib system with at least one cylinder (3a,3b) for actuating it, and a device for monitoring the cylinder pressure indicating the crane load. The flow of hydraulic fluid to the cylinder is controlled by varying the cross-section of a valve (11). Depending on the time variation of the cylinder pressure or the load on the piston, a signal is generated that actuates the drive to alter the valve cross-section to reduce the measured pressure or load.
