According to statistics from China Construction Machinery Industry Association, by the end of 2017, the main products of China's construction machinery were about 6 million 900 thousand to 7 million 470 thousand units. There are 1 million 557 thousand to 1 million 686 thousand hydraulic excavators, 65 thousand and 700 to 71 thousand and 200 bulldozers with 73.5kw (100 horsepower), 1 million 490 thousand to 1 million 614 thousand loaders, 23 thousand and 600 to 25 thousand and 500 platforms, 21 thousand and 200 to 23 thousand pavers, roller 133 thousand ~ 144 thousand, wheel cranes to 100 stations, tower cranes 70 thousand stations, 2 million 446 thousand to 2 million 650 thousand forklift trucks, 378 thousand to 409 thousand concrete mixer trucks, 62 thousand and 300 to 67 thousand and 600 concrete pumps, 55 thousand and 800 to 60 thousand and 500 concrete pumps, and 59 thousand and 900 to 65 thousand and 700 mixing stations.
Explain:
(1) the year of statistics. It is understood that the construction machinery is generally used for 10 years. Although some imported advanced equipment, especially the large equipment used for more than 10 years, some even used for more than 20 years, the equipment condition is still normal, but considering the use of most of the equipment, we still take 10 years in the statistics.
(2) the statistical method of domestic actual demand: the sales volume of the same year of the domestic enterprises + the same kind of products of the same year - the same year's export volume of the same kind of product = the actual demand of the domestic market.
(3) after adding the actual demand of the country in the year 2008~2017, the increase of 20% will be the national total. Because there are three factors in Statistics: incomplete statistics, import volume that has not entered the customs statistics, and over 10 years of service life. Therefore, it is advisable to increase 20% to 30%.
(4) the main reason for the abolition of the elevator and the escalator since 2005 is that the main reason is that it is consistent with the statistical scope of the world and is more comparable. The scraper has been cancelled, because its sales volume has decreased year by year since 2000, and only tens of tens of units in 2015. Compared with the total amount of construction machinery, it can be ignored.
(5) the concrete pump truck was only listed in the customs in 2013, and the concrete mixing station has no single tax number so far. It can only be estimated by domestic sales volume. The customs statistics of graders and road builders are in the same tariff code, so it is impossible to accurately count the actual import and export volume of the graders, and their holdings are estimated. Every year, tens of thousands of small and simple products are not included in the tower crane.
(6) the number of concrete pumps in the above forms includes towing pumps and vehicle mounted pumps.
(7) the survey and statistics of the maintenance of construction machinery and the accumulation of experience and data accumulation of the old leaders and old experts of the China Engineering Machinery Industry Association, and the association of the relevant branches and enterprises are also actively cooperated and thanks.
(8) the above survey statistics and calculations can not guarantee their absolute accuracy due to the limitation of existing conditions and the change of data caliber, for reference only.
