Great plains body type, mainly for earthworks in shaping and leveling operations, widely used in highways, airports and other large area of ??ground level jobs. In recent years, as China's roads, bridges and expanding variety of large-scale investment in road projects, Grader be widely used in various projects. Its broad market prospects for a time in the country caused a wave of "grader" craze. Due to the great plains of the body type, high energy consumption, space requirements for special, but also has a certain degree of operational risk, making the training of a qualified motor grader operator huge costs, difficulties, the number of motor grader operator on the market is extremely scarce. Xuzhou Hanlin Technology Co., independent research and development, design, born grader operation teaching instrument of production, from the fundamental solution to many problems. He can make students master the theoretical knowledge and basic skills as quickly as possible, so that students get psychological and emergency response capabilities integrated training; training machines actually save time and reduce accidents during training students real machine. Teaching instrument, small footprint, low power consumption, without environmental constraints, effectively reducing the human, material and financial burden of training daily operations, improve training efficiency, saving training costs. Meanwhile strict assessment criteria, to eliminate human examination. Products through international software industry standard software in the international software engineering, systems engineering and quality management capability maturity model integration CMMI3 class certification, ISO20000, ISO27001, ISO9001 certification. Through the practice of using the product recognition and praise. Features a combination of teaching and practice students through hands-on, not only the practical operation of the training, and theoretical knowledge, learning and assessment. Rich multimedia knowledge, learning both the depth and breadth of another high-risk industry, coal production, particularly complex talent needs. Enhanced security alarm with illegal operations and smart correction for non-standard operating personnel operating give warning, and give the correct method of operation the boot prompt to make safety habits. Flexibility training from the weather, whether it is day, rainy days can batch trainees practical operation training, training time flexibility to adjust according to the situation of training units. Saving training costs, increase production efficiency training equipment capital investment, a one-time, you can continue to use in the future long-term training, and training units can also be combined with the existing multimedia teaching equipment to implement training. Compared to the "training base" of millions of investment projects and the actual results, the virtual reality exercise program can greatly save huge amounts of money invested, and effectively to achieve the training effect. Help shorten the training cycle and reduce the accident rate among trainees in the theoretical study and practical training (work) to achieve seamless links to make the training cycle was shortened, students quickly adapt to the work environment, you can significantly reduce the misuse of new students caused by accidents and work put into production as soon as possible, indirect expenses and capital investment savings and increase efficiency. Help to improve the utilization of production equipment downhole equipment if the trainees to learn and operate, it will directly affect the production, and the use of virtual teaching instrument teaching is not necessary to take up the production and use of the device.
