Abstract

According to the invention a remote control device is produced for the movement at different speeds of cranes assembled on motor vehicles. The device as of the invention includes a hydrostatic unit (60) for supplying the actuators (10, 20, 30 and 40) of a crane (2) and a control button strip (90) for the solenoid valves of the flow distribution and regulation unit in which each pushbutton (91, 92, 93, 94, 95, 96, 97, 98) of the button strip (90) controls one and only one of the crane's movements. Furthermore, the same pushbutton is suitable also for controlling different speeds of the same movement. Each pushbutton is of the two position normally open type with spring loaded return to pressure release and tactile perception of the switching of the contact for facilitating the operator's task. The device as of the invention also allows the change from one speed to another in a sequential, progressive and discrete manner both when accelerating and slowing down.
