Introduction: Excavators have always been the most common type of equipment used in construction machinery. Many people dig their own buckets of gold through excavators and leasing excavators. There are a large variety of excavators on the market. In the past, excavators were used in the market. At the same time, everyone is willing to purchase excavators imported from Japan, the United States, and other countries. However, with the development of domestic manufacturers' technologies, more and more people have chosen to purchase homemade excavators. The following Xiaobian will give you the choice of domestic used excavators. Friends made a few small suggestions. First of all, to check the size of the arm with or without cracks, weld marks, there are cracks to prove that the working environment before the machine is bad, the machine is seriously damaged, buy back and take care of. Secondly, check whether each oil cylinder bumps. If there is a bump, it will prove that the machine is damaged and the oil cylinder will leak. Even if it is replaced with a new oil seal, it will continue to leak for a short time. The third is to check the 4 rounds, check the drive wheel, guide wheel, roller, towing and track wear, the chain is original, replaced the chain is to prove serious damage. Looking at the two heart walking motors, whether the walking speed is the same or not, a quick one and a slow one indicate a problem. Tracks and individual wheels carefully look for wear. Marriage first to see the chassis. Finally, check the engine, test whether there is noise, whether the power has a weak condition, whether the operation is a sign of a speed drop, take a look at the amount of exhaust gas, and a larger displacement indicates that the engine operation time may be long, requiring overhaul.
