Method for operating engineering machinery and engineering machinery
The invention relates to a method for operating a construction machine and to a construction machine having a hydraulically operated working device, in which the working device is supplied with hydraulic fluid via at least one hydraulic hose, which can receive a first high pressure and at least one second low pressure that is lower than the first pressure depending on the operation, wherein the at least one hydraulic hose is at least partially wound on a rotatable hose reel and is unwound from the hose reel and rewound onto the hose reel as a function of a moving movement of the work implement. Furthermore, according to the invention, a control unit is provided which controls the pressure of the hydraulic fluid in the at least one hydraulic hose independently of the operation of the work tool in such a way that a predetermined minimum pressure is present in the hydraulic hose when the at least one hydraulic hose is wound onto the hose reel.
本发明涉及一种用于运行工程机械的方法和工程机械，工程机械具有液压运行的工作器具，在其中通过至少一个液压软管给工作器具供应以液压流体，其取决于运行可以接受高的第一压力和小于所述第一压力的至少一个低的第二压力，其中，所述至少一个液压软管至少部分地卷绕在可转动的软管卷筒上并且根据工作器具的移动运动从软管卷筒展开并再次卷绕到软管卷筒上。此外根据本发明设置有控制器，控制器独立于工作器具的运行如此控制在所述至少一个液压软管中的液压流体的压力，使得在所述至少一个液压软管卷绕到软管卷筒上时在液压软管中存在预设的最小压力。
