Apparatus and method for compensating the contraction of fluid in a telescopic boom hydraulic drive, and compensation mechanism to compensate for the contraction of fluid in a hydraulic actuation of a telescopic boom crane
Apparatus and method for compensating the contraction of fluid in a telescopic boom hydraulic drive, and compensation mechanism to compensate for the contraction of fluid in a hydraulic actuation of a telescopic boom crane
Apparatus and method for compensating the contraction of fluid in a telescopic boom, and hydraulic drive.Compensation mechanism to compensate for the contraction of fluid in a telescopic boom of a crane hydraulic drive apparatus to compensate for the contraction of fluid in a telescopic boom hydraulic drive may include a monitor determining the angle of elevau00e7 Will the telescopic boom, a supply of hydraulic fluid, and a fluid control responsive to the monitor.The control of fluid provides hydraulic fluid supply to a hydraulic cylinder, controlling the length of the telescopic boom when the elevation angle exceeds a predetermined threshold angle to compensate for thermal contraction of hydraulic fluid and thereby prevent ret Ration of spear headed. It is also presented a method according to the invention.
