Because of construction machinery mall new machine is now gradually becoming transparent and rapid increase during the full sale of used excavators, construction equipment has now entered the replacement of the corresponding second-hand construction machinery mall is entering a "post-mall." But the supply of second-hand excavator, known as Europe and other developed countries, "gold industry," second-hand construction machinery trading business but failed to get professional attention. In the emphasis on machine sales and snatch market share of the domestic construction machinery mall situation, all the current status of second-hand construction machinery mall worrying.

The basic price by excavators time to determine. In China, life in general mechanical design engineering for 10 years (in general, due to the introduction of new products, the use of a 10-year old machine, even at very low prices are also available), the average time of about 2000 hours. In normal use the acquisition of second-hand excavators, engine overhaul cycle of 10,000 to 15,000 hours, often in the hydraulic pump life of 20,000 hours, while others, such as a hydraulic motor, gear box, the main control valve assembly, and other parts of life but also longer, that is to say the new machine, in the absence of unexpected circumstances within five years without major repairs.
