Editor's Note: At the unprecedented 2014 Bauma China exhibition, it could be described as a gathering of merchants and major brands. Construction machinery businesses from home and abroad brought out their new and superior products, flagship brands, and through various demonstrations, attempted to showcase their corporate strength and new image at the grand event to win more customers' favor. However, in the competitive exhibition, from the perspective of 'dynamics', the reporter saw another side of why XCMG's exhibits were popular—this is the appearance of its 'grab, dig, drill', which is both powerful and 'dynamic'. 　　This hydraulic grab has excellent performance and 'steadily' grabs the foundation. In April 2014, XCMG's self-developed XG600D diaphragm wall hydraulic grab successfully rolled off the production line. It is currently the largest tonnage diaphragm wall hydraulic grab in China and also the domestic product with the deepest trenching capability for diaphragm walls. It was born with the development of underground diaphragm wall structures toward ultra-thick and ultra-deep directions. Its overall design places great emphasis on human care; while ensuring stability and reliability, it greatly improves operating comfort and safety. The maximum lifting force of 60 tons ensures it can perfectly construct underground walls up to 105 meters deep and 1.5 meters thick.
　　On the basis of inheriting excellent quality, XCMG products are renowned both inside and outside the industry for practicality and durability. The XG600D diaphragm wall hydraulic grab, known for its 'stability', is equipped with a hydraulic telescopic special chassis with a maximum outer width of 4900 mm, and safety control technologies such as bottom-touching protection, height limit, and automatic alarm, enabling the equipment to serve customers with high efficiency and high stability; the original front-and-rear arrangement of double winches with a single-row rope structure, with the largest single-row rope capacity of 80 meters at home and abroad, effectively improves the service life of the wire rope and reduces maintenance costs and downtime losses by 20%; the mature load-sensing system paired with an imported Euro III Cummins engine effectively improves fuel utilization and achieves energy savings of 15% to 35%; it has a full series of push-plate deviation-correcting grabs, gantry grabs, and ultra-thin grabs, which can realize grab rotation, lateral deviation correction, and longitudinal deviation correction functions. 　　Due to excellent performance and 'steady' grabbing, the construction effect is good. After XCMG's first XG600D arrived in Foshan, it attracted industry attention. On this trip, the XG600D underground diaphragm wall hydraulic grab participated in a project with a total investment of about 3 billion yuan, which will become the 'first German service center in South China' upon completion.
　　After the XG600D underground diaphragm wall hydraulic grab completed assembly and debugging, it immediately drew admiration from construction unit personnel: the equipment has an innovative design and a grand appearance, the crawler traveling device has high stability, the whole machine adopts a centralized lubrication system, and it is equipped with cameras for monitoring the wire rope and the rear of the equipment. After the construction guide wall was completed, the project department immediately arranged for the XG600D to carry out construction. With the equipped heavy-duty push-plate grab and its advanced control system, it completed the construction of one trench hole to high standards in just 6 hours. Its efficient construction efficiency and precise verticality of the trench were recognized by the project department and also dispelled the project department's concerns that the XG600D could not complete the mudstone crossing. 　　It is worth mentioning that along with the grab, the XG600D diaphragm wall grab virtual operation instrument was also exhibited. In order to let more people understand and become familiar with the construction principles of the underground diaphragm wall hydraulic grab, the company specially invested in developing the world's first underground diaphragm wall hydraulic grab virtual operation instrument. To be closer to the real machine operation feel, the seat, operation handles, buttons, and switches of the virtual operation instrument all refer to the layout of the real machine. Its dignified and grand appearance, exquisite virtual images, and realistic animation effects, coupled with the patient guidance of the interpreter, made the flow of people coming to operate the simulator endless. Through operating the virtual operation instrument, visitors gained a deeper impression of this underground diaphragm wall hydraulic grab.
