据中国工程机械工业协会统计,截止到2011年年底,中国工程机械主要产品保有量约为504万～547万台。其中,液压挖掘机121.2万～131.3万台,73.5 kW(100马力)以上推土机7.7万～8.3万台,装载机151.4万～164.1万台,平地机2.8万～3.0万台,摊铺机1.9万～2.1万台,压路机11.8万～12.8万台,轮式起重机21.1万～22.9万台,塔式起重机26.7万～28.9万台,叉车130.2万～141.1万台,混凝土搅拌运输车16.5万～17.9万台,混凝土泵车4.0万～4.3万台,混凝土泵5.9万～6.4万台,混凝土搅拌站3.2万～3.5万台。此外,还有大型专用工程机械如凿岩台车、隧道掘进机、履带式起重机、高空作业设备及消防车、桥梁建设专用设备等,虽然社会保有量不高,但单台价值高昂,在施工中的作用
According to statistics from China Construction Machinery Industry Association, as of the end of 2011, the holding amount of main products of China’s construction machinery was about 5.04 million to 5.47 million units. Among them, 1,212,000 to 1,313,000 hydraulic excavators, 77,000 to 83,000 bulldozers above 73.5 kW (100 horsepower), 1,514,000 to 1,641,000 loaders, 28,000 to 30,000 graders, and 19,000 pavers ~ 21,000 units, 118,000-128,000 compactors, 21,001-299,000 wheel cranes, 267,000 -289,000 tower cranes, 1,321,000 ~ 1,411,000 forklifts, 165,000 ~ 179,000 concrete mixing trucks 40,000 to 43,000 concrete pump trucks, 59,000 to 64,000 concrete pumps and 32,000 to 35,000 concrete mixing plants. In addition, there are large dedicated construction machinery such as rock drilling trolley, tunnel boring machine, crawler cranes, aerial work equipment and fire engines, bridge construction equipment, etc., although the social ownership is not high, but the single high value in the construction In the role
