Energy Saving and Emissions Reduction Concerned about Mixed Technology to Accelerate Development of Construction Machinery

The growing global demand for energy and the scarcity of resources are intensifying, and energy-saving and emission-reduction are attracting more and more attention all over the world. The development of hybrid technology has become one of the important measures for energy conservation and emission reduction. In 2010, the sales revenue of the construction machinery industry exceeded RMB 400 billion, making it one of the fastest growing industries in the machinery industry. However, due to the large use of construction machinery, high fuel consumption, poor discharge, and serious pollution, it has gradually become the main target of energy conservation and emission reduction.

There are frequent start-stops and reciprocating motions in the construction site of construction machinery. When decelerating and braking, a large amount of energy will be released. Therefore, the use of hybrid technology for energy recovery and reuse has become an effective measure for saving energy and reducing consumption of construction machinery. Hybrid power is produced in accordance with the development of the times. The heat wave of saving energy and reducing consumption promotes it as the future development trend. The fuel economy makes it a favored person in society. As one of the pillar industries of the national economy, the construction machinery industry continues to independently innovate and actively develop new types of hybrid power products, contributing to China's energy conservation and emission reduction.

Hybrid power is based on "fuel saving" as its selling point, energy saving and environmental protection as its goal, and it can be described as a pioneering move to benefit the country and the people. Therefore, engineering machinery hybrid power products will be the future development trend. At present, there are many hybrid applications in excavators, forklifts, bulldozers, and other products. Caterpillar, Case, Komatsu, and domestic companies such as Sany, Xugong Group, Liugong Machinery, and Shanhe Intelligent have launched their own hybrids. Power products.

As early as 2003, Hitachi Construction Machinery produced the world’s first hybrid-powered wheel loader. In May 2004, Komatsu developed the world’s first hybrid hydraulic excavator; in April 2006, New Holland and Kobe Steel jointly developed the 7t hybrid hydraulic excavator. In 2007, Zhanyang Power Heavy Industries introduced the JYL621H wheeled hybrid hydraulic excavator. In 2008, Volvo developed the L220F hybrid wheel loader; In May, Case introduced the CX210B hybrid excavator. In November 2009, Sany Heavy launched the SY215C hybrid hydraulic excavator at BICES2009. In February 2009, Doosan Heavy Industries Co. announced the development of the hybrid excavator. It is expected to be completed in 2014. In October 2010, XCMG introduced the ZL50G hydraulic hybrid loader. In 2010, Liugong Machinery Co., Ltd. introduced the electric hybrid loader CLG862-HYBRID and the hybrid excavator CLG922D. Smart launches the hybrid excavator SWE210Hybrid; in 2010, Xuzhou Hengtian Del Heavy introduced an oil hybrid excavator. In order to increase the competitiveness and market share of the next generation of products, major construction machinery manufacturers in the world have started to apply and research the hybrid power system in construction machinery.

The hybrid power of engineering machinery can effectively reduce fuel consumption and tail gas emissions, which has great market potential. At the same time, with the continuous improvement of hybrid R&D and application technologies, it is necessary for the whole machine companies and supporting parts companies to make joint efforts to stimulate the development of related parts and components manufacturers. Enhance the technological level and market competitiveness of China's construction machinery industry so as to realize the transformation of China's construction machinery from a manufacturing country to a manufacturing powerhouse!
