Truck crane hydraulic system One, domestic and foreign automobile crane hydraulic system new technology ( a ) on truck crane hydraulic system security problems research The 1 generation of intelligent overload limiter of crane in automobile application The third generation of microcomputer overload limiter ( XTⅢ), with independent intellectual property rights of domestic electromechanical integration device. The device is composed of a main machine part and a sensor part, microcomputer control, modular structure. Installation and commissioning of all the key operation, large screen LCD dot matrix display, in the setting of parameters and the display is very concise, do not adjust any potentiometer, the debugging is simple and intuitive, friendly interface. Limiter adopts digital and large scale integrated circuit, reducing the failure, increases the capacity of resisting disturbance, thereby improving reliability; when the crane is more than the rated capacity or stroke, can automatically alarm and cut off the crane to the dangerous movement of the loop, but allows it to move towards a safe direction; system of automatic fault detection, the results showed; low power ( power consumption less than 10W), digital circuit using all the CMOS chip; a black box function, automatic recording overload time and then the operational parameters; data and parameters of all Chinese characters display graphics presentation, numerical accuracy, convenient operation, stick out a mile, no operator is required to memorize the password prompt; setting function, prevent parameter error setting; good generality, without altering the host circumstances, as long as the software changes, can meet various types of heavy machinery; machine memory a plurality of rated load curve, satisfy various working continuously alarm calls; the sensor " drift " and " drift " can carry out automatic regulation and compensation with sound and light alarm function. The technique has been used in many domesti
