Abstract
Concrete machinery refers to the equipment applied in modern concrete
mechanical engineering for production, transportation, and concrete paving,
etc., including concrete mixers, concrete mixing plants, concrete pumps,
concrete mixing trucks, concrete jets, concrete vibrators, and steel
processing machinery. The general concept of the concrete machinery means "one
plant, three vehicles ", namely concrete mixing plant, concrete mixer truck,
concrete pump and concrete pumping vehicle. Concrete machinery is the
important equipment in great demand for infrastructure, widely used in
industrial and civil construction, national defense construction and other
projects. After decades of development, concrete machinery has become a key
part of engineering machinery in China, with considerable production capacity
and accounting for 6% of the whole construction machinery industry.
Even faced with global economic slowdown in 2008, Chinese concrete machinery
export still maintained a good growth. In 2008, 2,149 concrete pumps were
exported, valuing at US$102.92 million. In quantity, the export increased
13.5%; but in capital, the export decreased 24.1%; the average export prices
rose somewhat. Only 3,263 concrete mixers were exported, up 21.9% from 2007;
the export valued US$ 188.42 million, 37.4% up over 2007, maintaining
continuous increase.
Currently, in Chinese concrete machinery industry, there are more than 200
enterprises, producing diversified products. China has the leading status in
the production of concrete pumps. In 2007, SANY Heavy Industry Co., Ltd
participated in the construction of Shanghai World Financial Center with 492
meters in height. At the end of Dec 2008, Zoomlion Heavy Industry Science
& Technology Development Co., Ltd. transferred super viscous C100
high-performance concrete pumps to Guangzhou International Financial Center
(West Tower) with the height of 432 meters by super high-pressure concrete
pump. In 2008, SANY successfully manufactured a 72-meter pump, the highest
pump in the world.
In addition to the conventional specifications of 32m, 37m, 42m, 45m, 48m, 52m
and 56m, SANY also produces the products of 38m and 40m. In January, 2007,
SANY produced the super long-arm pump with 66m. However, the main
specifications of SANY are 37m, 45m, 48 and 56m. The specifications of
Zoomlion' s pumps ranges from 37m to 56m, but the specifications applied most
widely are 37m, 44m and 47m. Putzmeister Shanghai factory produces such key
models as 36m, 38m, 42m and 46m. The mainstream models of Shanghai Hold
Machinery Co., Ltd. are 22m, 37m, 40m, 43m and 47m. It is worth mentioning
that the short-arm pumps with the length of below 27m only include the ones of
25m produced by SANY and 22m by Shanghai Hold Machinery. The current sale of
short-arm pumps account for less than 2% of that of the overall pumps, but the
cost of short-arm pumps is low, which benefits the construction of buildings
in dense urban areas, so the development of short-arm pumps is promising.
Concrete machinery is technology-intensive, capital-intensive and
personnel-intensive, so it is difficult to enter the field. The main barriers
for entering the concrete machinery industry lie in technical capabilities,
qualifications, financial strength and customer service. Concrete trucks,
concrete pumps and vehicle pumps are the modified automobiles, which are
subject to the industrial policies of China. The manufacturers must be
qualified for the production of civil converted vehicles, and they must
complete test reports and apply for bulletin catalog to the government before
marketing each vehicle. In general, the application period lasts long.
