I'm looking for a master who can repair a bulldozer in Shanghai or Hangzhou. Let me introduce one to you. Thank you
(three) it is very important to check the hydraulic cylinder and tubing: 1, oil leakage means that the whole oil circuit is contaminated. The best case is that the hydraulic cylinder chrome surface is free of scratches, dents, or oil spills. If hydraulic oil is leaking out, it is possible that the dust has contaminated the hydraulic system. 2, also make sure that the cylinder wall is not damaged or dented. The gap between the cylinder and the cylinder wall is very small, as long as there is a debris in the pipeline, will cause the cylinder due to wear and a large number of metal chips, and the residual to the hydraulic system. (four) guard against welding on the body: 1, carefully check whether there are cracks and non original welding marks left behind, these things indicate that the machine has been excessive use. 2, there is a good method, is to use a piece of candy bar on the arm and arm position, to see if there is no dislocation and distortion. Pay special attention to excess plate repair. 3, two mobile phone may have some scratches and dents on the machine, but if there are too many patches may mean that this equipment has been used for a long time.I am a bulldozer manufacturer, and now there are many ways of selling bulldozers, such as financing, staging and so on. I suggest you buy a new car and do financing, and the down payment will be about 100000!
Matters needing attention in purchasing used construction machinery:Second hand construction machinery generally cheaper, many are not three bags of service, so when buying should pay attention to. 1, such as excavators, pay attention to hydraulic servo control rod than the old joystick better, and sometimes push the soil board is not standard equipment
Two) on the bucket and boom: 1, the equipment is not always a mining machine, builders sometimes use them to pile up or use them to lay pipes. Therefore, you need to pay attention to the bucket situation and make sure there is no problem in piling, crushing and walking device. 2, there is an important part of the bucket cylinder connection pin, bushing, must be on these places to check the elastic. Many problems arise from lack of maintenance and inspection. When you move the machine, move the bucket, the bucket and the back arm, you may see the pin or the cylinder moving, but the bucket and bucket do not move. This is due to the looseness of the pin and bushing parts. 3, another key point to connect oexamine arm and excavator parts. If the connections under your rear arm are over worn, it may cause loss of the value of the entire device.
