1, the product independent design, surface spray, beautiful appearance, small working radius, can work in a narrow area. 2, the use of Japan KYB plunger variable pump, so that the big arm, the forearm, the rotation form their own independent hydraulic system, to achieve fast and smooth and strong operation. Compared with gear pump, it has obvious performance advantages. 3, the main valve adopts the parker main valve, with efficient performance and excellent operating performance, with crushing pipe and control device, the installation of crushing hammer can be broken work. 4, Rotary Eaton 2.5K rotary motor, reliable quality, large displacement, large torque, strong adaptability to working conditions. 5, Eaton imported walking device, more stable performance, more reliable quality. 6, the left and right pilot handle choose short handle control valve, without affecting the performance of the premise, it is more convenient to get on and off the car, prevent misoperation, and increase safety. 7, imported Yanma three-cylinder water-cooled diesel engine, more powerful, imported hydraulic system, high configuration, superior performance, low fuel consumption. 8, a wide range of operations, the use of quick replacement of joints, optional rotary digging drill, crushing hammer, loading bucket, grab and other accessories. 9, reduce maintenance and operating costs, liberate labor, improve mechanization, low investment, high return.
