First Hybrid Excavator in China Independently Innovated by SUNWARD Rolled off th

    It is said that, SUNWARD have made a stride on energy-saving and environmental protection technology in China construction machinery industry with the first commercialized hybrid excavator successfully rolled off the line. Also, it’s a milestone on hybrid excavator commercialization in China as well as a smash on foreign companies’ monopolization of hybrid drive technology.

China Construction Machinery’s Weakness of Energy Conservation and Emission Reduction

    As the global environmental deterioration and resource shortage, energy conservation and emission reduction become the key point in the study of excavator manufacture enterprises. The hybrid drive technology which is originated from car has an advantage of achieving combinatory operation with different drive system, thus machinery improves energy utilization ratio based on the advantage of hybrid drive system. The accomplishment of energy conservation and emission reduction, as well as the general character of operational principle between construction machinery and car make hybrid drive technology be recognized as the most popular energy conservation measure of excavator.

    To take up the dominating position of hybrid drive technology’s application in construction machinery industry, many famous foreign excavator manufactures are launching hybrid excavator while China excavator enterprises are importing foreign mature technology. In this condition, Chinese enterprises have to pay enormous technology transfer fee and all kinds of “technology deprivation” during the application period for lacking of proprietary intellectual property rights.

SUNWARD Smash Overseas Monopolization of Hybrid Drive Technology

    In order to smash overseas construction machinery enterprises’ monopolization of hybrid drive technology, SUNWARD set up a team for scientific research to tackle the key research project. The team insists on “commercialization start from basic principles study to simulation test; from bench scale test to prototype manufacture” and independent innovation in order to find a sustainable development way of energy conservation and emission reduction for Chinese construction machinery.

    “Almost five years’ technology accumulation and scientific research, we traversed an extraordinary course which began with the study of hybrid excavator principles to simulation test, bench scale test, and commercialization at last. All done with independent innovation! We’ve find an outlet for Chinese construction machinery applying hybrid drive.” SUNWARD president He Qinghua said proudly.

    According to SUNWARD engineers’ introduction, the hybrid excavator adopts parallel connection of hybrid drive system to achieve the same operation capacity, but the output power will be less. The hybrid excavator will reduce the emission while conserve the energy. “The average result of energy conservation is up to 20%, and the noise index reduces more than 50% when the machine swings.” said the test engineer.

    SUNWARD merged the concept of “green, environmental protection and health” into every product’s innovation and manufacture to achieve “energy conservation and environmental protection” under the assurance of products function and quality; continuously tried to reduce the pollution to environment when machines are designed, manufactured and applied, as well as improve the utilization ratio, cost and energy consumption based on the effort of technology innovation. From the large green pile foundation equipment such as hydraulic pile driver and rotary drilling rig to down-hole drilling rig, electric excavator, electric forklift and hybrid forklift, SUNWARD had a lot of successes in manufacturing products with the character of energy conservation and environmental protection. SUNWARD hybrid excavator will promote the various application of hybrid drive technology in excavator which presents the “exclusive product in construction machinery”.
