How to determine the basic price of the basic price by mechanical use time to determine. In China, the use of life expectancy is usually planned construction machinery is 10 years (generally speaking, because the introduction of new products 40 used excavators, using 10-year old machines are also available for even very low offer), the average use of time to about 2 000 h. During normal use, the number of engine overhaul cycle life also 10 000 ~ 15 000 h, pump life span is usually 20 000 h or more, while others, such as hydraulic motors, gear boxes, main control valves and other assembly parts To longer, that is to say about the new machine, in the absence of unexpected circumstances within five years of having to overhaul. The excavator, for example, in accordance with the current specifications used equipment depreciation, depreciation of machinery by 20 percent the first year, decreasing 5% per year in the future to account for the basic price, namely 20% depreciation in the first year, second year 15% depreciation first 10% Depreciation year 1 personally used excavators, the fourth annual depreciation of 5%. The first five years in the future, usually because of aging of some parts, normal wear and tear, and some not estimate the reason, it is necessary to carry out a series of renovations to the device used excavators Price, which makes equipment depreciation rate steady at about 5% or so or less, so that the offer steadily. Along with the upgrading of the skills of all aging and the machine itself, 10 years after the offer to 20% below the whole quote. 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. Used excavator normal use, the engine overhaul cycle of 10,000 to 15,000 hours, often in the hydraulic pump life of 20,000 hours, while the other life such as hydraulic motors, gear boxes, the main control valve assembly, and other parts still more Some long, that is for the new machine, in the absence of unexpected circumstances within five years without major repairs. 135 used excavators, used excavators, used excavators Kim Ho Jin Hao from Shanghai Used Construction Machinery Co., Ltd ..
