Why is the last eight rounds of dump trucks limited, high or slow down?
You mean that the container hydraulic top rises up to a limited height, and there is no slow down function in the drop case, is it? I am on the Dongfeng Hercules after eight wheel truck to Hubei, Shiyan Dongfeng Dongfeng Hercules production side after the eight round of mine dump truck manufacturers, the new eight wheel truck cargo lift device is divided into two kinds, the latest is pneumatic lock control lift, the safety coefficient of this latest the high point of stability, but this kind of pneumatic lock control lift generally did not slow down, the cab of the pneumatic lock switch three stalls (down + + stop lift) so as to slow down;
Best answerLimit height, all cars must be configured, slow down function, and now most of the cars should also have, and your valve is not with slow down function, or you did not notice, you carefully check! Really do not want to change their own hand control valve and reversing valve.
But there is also a kind of old-fashioned oil circuit control - oil transfer valve, if you install this, you can achieve slow down, turn the valve off is fast down - turn the valve less, put one point is slow down. Your car should be fitted with a new gas control valve, there is no slow down, no problem, used to the good, this is also relatively stable installation method, not easy to bad.For your limited height, all dump truck box assembly will be set when the limit valve - that is, limit the height of the container rise, if you do not set the limit height, it is easy to lift the cylinder after flushing, resulting in accidents. I hope to help you, you want to see more Dongfeng Hercules after eight wheel truck parameters, can be recommended to the Dongfeng car 360dfc website to see, Dongfeng Motor Home Shiyan Carrie source company sold Dongfeng Hercules after eight wheel truck is also good.
