The invention relates to a method for controlling a hydraulic lifting drive (1) of a mobile working machine, in particular a ground vehicle, for raising and lowering a load receiving means (3), the lifting drive (1) having a lifting cylinder arrangement (10a, 10b) and a control valve arrangement (12) which is connected to the lifting cylinder arrangement (10a, 10b) guided to the lifting cylinder arrangement (10a, 10b). 10b), to a container line (18) guided to the container (17) and to a delivery line (14) connected to the pump (15), an operator controlling the ascending and descending operation of the lifting drive (1) by manually operating a lifting drive operating element (42) operatively connected to the control valve device (12). According to the invention, in the case of no load on the load receiving means (3), an operator authorizes the high-speed descending operation during the descending operation of the lifting drive (1) while actuating the lifting drive actuating element (42) by actuating an authorization actuating element (44), the descending volume flowing out of the lifting drive (1) is increased by means of a cross-sectional enlargement produced by means of a cross-sectional enlargement device (47) in the hydraulic line from the lifting drive (1) to the container (17). The invention also relates to a device for carrying out the method.
一种用于控制移动式作业机械、尤其地面运输工具的液压升降驱动装置(1)的方法,用于使负载接收器件(3)上升和下降,升降驱动装置(1)具有升降缸装置(10a,10b)和控制阀装置(12),控制阀装置连接到被导向至升降缸装置(10a,10b)的消耗器管线(19)上、连接到被导向至容器(17)的容器管线(18)上和连接到与泵(15)处于连接的输送管线(14)上,操作人员者通过手动地操作与控制阀装置(12)处于作用连接的升降驱动装置操作元件(42)来控制升降驱动装置(1)的上升运行和下降运行。提出,在负载接收器件(3)上不存在负载的情况下,操作人员在升降驱动装置(1)的下降运行中在操作所述升降驱动装置操作元件(42)同时通过操纵授权操纵元件(44)来授权高速下降运行,其中,从升降驱动装置(1)流出的下降体积流通过借助于在升降驱动装置(1)至容器(17)的液压管路中的横截面扩大装置(47)产生的横截面扩大而增大。还涉及一种用于执行所述方法的设备。
