The award ceremony of 2012 TOP50 products in Chinese construction
machinery, which shows the strength in R & D of a company and
recognition for stability of the products, was held in Beijing on
Mar.29, 2013. The all terrain crane model QAY1200 from XCMG Hoisting
Machinery Division won this honor and enjoyed a high praise considering
its advance technology and perfect performance in engineering
application.
Not only the all-terrain crane, the large-tonne crawler cranes also
enjoy a high reputation for their outstanding performance. There is only
a few super-large tonne crawler cranes in China and a tense supply in
the world, those put in practical application are even less. The
XGC28000, 2000-ton crawler crane from XCMG, is among the top honor.
"China’s First Hoist” played a big role
XGC28000, used to be honored “China’s First Hoist” in the
industry, attracts much attention since its born. It not only marks a
new record in Chinese Crawler Crane Industry, but also marks a high
speed and strength to move forward to the world market and technical
pinnacle for Chinese companies. XGC28000 deserves “China’s First Hoist”
honor for its ranking several “first”s: Max lifting capacity, Max
lifting torque, and Max boom length, etc.
XGC28000 has gone through several tests in super-large engineering
applications since it was launched. In the construction site of Ethylene
project in Wuhan, Hubei province, which is the first integration
project in Asia with the largest crawler crane in application, XCMG’s
2000-ton crawler crane made a fully success with lifting 728 units of
equipments, totally counts 45124 ton, in which large equipments counts
110 units, regardless of the fact that the tasks are heavy and should
change working site frequently. The project successfully completed after
10 months’ tight lifting. Another engineering application was in a
petrifaction project in Maoming, Guangdong on June 8th,2012. XGC28000,
with 72 meters’ main boom, 640 ton super structure, 26000 T•M, 100% load
rate, took only one hour to put the hydrocracking reactor in right
position successfully. Another thing to be mentioned is that the
hydrocracking reactor is in high value and counts more than 1000 tons’
weight and 20 meters high. The third case took place in Huian, Quanzhou
on August 1st,2012. It was a refinery project with capacity 12,000,000
ton per year. Even though the space was limited, wind was strong,
temperature was high in summer, XCMG’s SGC28000 overcame all the
constraints to lift the residue oil first reactor, which counts 4.5
meters in diameter, 28 meters in length, weighing up to 740 ton, to the
right position. The max rated lifting weight under the mode main boom 54
meters with super-lift and 16 meters in diameter, exactly the mode used
in this project, is 745 ton, which means the load rate for the crane
reached up to 99.3%.
"Thousand-tonne Family” create records
The latest “Great Action” for the XGC28000 took place in
Sinopec Energy Chemical Base in Ningxia province on Dec.19th,2012. It’s a
project for making olefin from methanol with capacity 500,000 ton per
year. In this project, the separating tower, which counts 100.9 meters
high, 8 meters’ cylinder inside diameter, weighing up to 2300 ton,
should be put in its right position.
In this project, we took the disposable integral lifting instead of
four-section grouped lifting from the past. As the part to be lifted was
too heavy, we finally decide using the hydraulic tower crane lift the
up-side, and XCMG XGC28000 crawler crane lift the down-side. The crawler
crane adopted the combination of electro-hydraulic proportional control
technology with 60m boom and stepless speed regulating with accurate
control to ensure successful completion at the first attempt.
The job signifies that XCMG has made a new record in transporting
and hoisting of large tonne cranes. And this amazing work relies on
high-performance, stability and reliability of the crawler crane.
XCMG’s XGC88000, a 4000-ton crawler crane known as “World’s No.1
Crawler Crane”, which has been placed the first order by Sinopec, has
successfully completed the overload test with 4500 ton, making a
hoisting record in the world. XCMG did a solid work in R&D and
manufacturing the 4000-ton crawler crane since the project settled in
June, 2010. Signed joint development agreement with Sinopec during BAUMA
China 2010 in Shanghai, held seven rounds of talks with Sinopec on
product plan, the design finally get approved by leading experts from
five industries. April,2012, the government brought this project into
“National 863 Project”. Sinopec sent a supervision team to XCMG factory
after officially signing the contract by both parties. The project moved
into the assembly and testing step after all parts got ready in July,
2012.
We believe that after the 4000 tonne crawler crane be built and put
into use, XCMG thousand-tonne crawler crane families will surely run
among different construction sites for big projects around China, even
around the world, and contribute XCMG power to the world top engineering
constructions continuously.
