A number of product launches have been made at Bauma China in Shanghai from the key domestic manufacturers of construction and mining equipment. From Jiangsu-headquartered XCMG, these include a new large wheel loader, the LW1200K; a new 70 t hydraulic excavator and a new 60 t capacity ADT. XCMG states that the LW1200K is now the highest capacity wheel loader made in China; with a 6.5 m3 bucket and 12 t rated capacity, operating weight of 48 t and a dumping height of 3.73 m. It is equipped with a 391 kW Cummins engine, wet travel brake, guide control and ladder maintenance platform. It has a “strong breakout force and traction ensuring adaption to tough working conditions.
It also has an intelligent control independent ventilation system and drive axle ventilation system to ensure that the machine maintains the best heat balance temperature; with a load sensing hydraulic system helping to lower energy consumption. XCMG stated: “The successful sales of this model further highlight the leading edge of XCMG in the China earthmoving machinery industry…the launch of the LW1200K promotes XCMG to being in line with Western counterparts, becoming one of four giants who are capable of developing this level of products in the world.” The model successfully passed evaluation tests from multiple industry experts at Jilin University, Beijing Institute of Technology, Southeast University, and the China University of Mining & Technology.
The company also says that it invested significant capital to introduce automotive-type manufacturing procedures for the production of entire wheel loaders. The new XCMG XE700 70 t hydraulic excavator follows the successful development of a 45 t excavator. The company states: “The success of the XE700 hydraulic excavator marks the growing maturity of XCMG technology in developing large-tonnage excavators and a solid step forward to independent innovation, product upgrading and market expansion.” The machine has a Cummins QSX15 engine and standard bucket capacity of up to 3.5 m3. The company also has a design for larger XE900 excavator with a bucket capacity of up to 5.5 m3.
Finally, XCMG has shaken up the ADT market with the unveiling of a 60 t machine, the DEE60, which add to 30 t and 45 t models in its existing range. The DAE60 has a Cummins QSK19 engine and AC drive giving independent control of the six wheel motors. The ADT has a 45 km/h top speed and is fitted with a hydro-pneumatic suspension and a hydraulic dry disc braking system.
