G9138 is a high-speed, high efficiency, high precision and versatile product developed by SDLG after full investigation of market demands, which can complete the ground leveling and trenching, slope scraping, bulldozing, snow discharge, loosing, compaction, material distribution, mixing, etc., and is widely used in highways, airports, defense engineering, mine construction, road construction, water conservancy construction, farmland improvement and other construction conditions.
Reliability
1. Rear drive axle: China Motor Grader uses the large speed ratio heavy drive axle to meet the low-speed finishing requirements, and is equipped with the no-spin limited-slip differential to greatly improve the dynamics and trafficability of the whole Mining Motor Grader; the heavy roller chain drive balancing box can swing by ± 15 °, to ensure that that middle and rear wheels touch the ground at the same time to significantly increase the overall traction and flatness of the blade operation.
2. Circle turn system: It uses a dual cylinder + circle turn valve structure, so that the dual drive gear is in engaged drive with the rotary gear ring; therefore, there are more meshing teeth quantity, low teeth stress and small abrasion; the cylinder has high efficiency, and the blade is circle turn under loads, so that it has high operation precision and high reliability.
3. Moveable blade control system: It is connected to the ear plate with the front frame through the composite bearing, so Motor Grader for Sale has high impact resistance, wear resistance, low friction coefficient and high reliability; the moving part applies the imported lubrication-free and maintenance-free composite bearing and high reliabilityï¼?
4. Gearbox: It is equipped with a yd13 power shift gearbox, which can change the speed in six-forward and three-reverse to adapt to the complex conditions.
5. Braking system: The standard single-loop fully hydraulic braking system,brake valve,charge valve and other key elements apply the mico products, which is safe and reliable, and the dual-loop fully hydraulic braking system moduleis optional.
6. Frame: The front frame is in a box-type frame structure, so it has high strength and high reliability; the rear frame is in a frame structure made by welding of the box-type beam, and the attachment device is easy to assemble so it has high reliability.
Energy-efficient
Hydraulic Motor Grader is equipped with a weichai engine, which is in good match with the advance yd13 gearbox to achieve optimum performance and fuel efficiency, so it is energy-saving and efficient.
Convenient
1. Instrument panel: China Road Grader uses the digital stepping instrument panel, so it has high man-machine interaction and easy detection and maintenance.
2. Multi-way valve: The multi-way valve is arranged in front of the cab, which is easy to maintain.
Final drive motor for Bobcat/ John deer/ Caterpillar/ Hitachi/ Volvo/ Hyundai/ Komatsu/ Kato/ JCB/ Doosan/ Sany excavator from 20 ton to 50 ton. As well, they also can use for Skid steer loader.
