Appears in the downhill track with 'skip-shift' gear action essentials should add the gear in a high - speed position or take 'grab block' (emergency downshift) measures, small excavator Caterpillar Used to be a machine to travel to its base and then stop to check, second-hand small excavator recovery, troubleshooting; if 'add block', 'grab the block' and again unsuccessful or 'skip-shift' (neutral in this case), the second-hand small excavator transaction, The driver can control the engine speed at medium speed (to prevent engine stall), Hunan second-hand small excavator, using 'pumping' approach so that the machine slid into the base, and troubleshooting. If the 'add block', 'grab the block' and again unsuccessful or 'skip-shift' (neutral in this case), and the machine and in the next big ramp (in this case the machine at a fast speed to its base ' dive '), should be promptly shut down in accordance with the downhill action essentials and requirements to stop, then deduct fault. Founding of New China to the former Soviet Union and other mapping imitation W501.W502.W1001.W1002 1930s - 1940s type mechanical shovels mainly China began excavator production history. At that time, the need of national economic construction and has established more than a dozen excavator production plant. 1967, China has independently developed a hydraulic excavator. Early successful development of products mainly include Shanghai Construction Machinery Factory of WYl00 model, W4-60 Guiyang mining machinery plant type, mining machinery plant in Hefei WY60 type excavators. Then appeared Yangtze excavator plant WYl60 type and Hangzhou of WY250 excavator and other heavy machinery. They took a very important step for the formation and development of Chinese hydraulic excavator industry.
