The grader is a kind of earthmoving machine with a shovel blade as the main working device. It is mainly used for ground leveling of roads, airports, farmland, etc., and for trenching, bulldozing, loosening, snow removal, etc. Construction machinery products necessary for building construction, water conservancy construction, and farmland improvement, such as mine construction and urban and rural roads.
Liugong constantly pursues innovation in product core technology, more than 1,000 R&D days and nights; more than 3,000 hours of reliability testing; experts from China, the United States and Britain teamed up to create a D-series grader for a variety of working conditions.
Liugong D series CLG4180 grader
The D series grader has more than 20 design patents. It is the fourth generation of grader products independently developed by Liugong. Compared with the previous generation Liugong grader, the new generation of products is particularly prominent in the control of vision and comfort, especially the self-developed The five-column cab with anti-roll/fall protection (ROPS/FOPS) provides an operator with a more intuitive view of the blade operation. Currently, it mainly develops 160-230 horsepower medium grade graders, including CLG4165D, CLG4180D, CLG4200D, CLD4215D and CLG4230D .
D series graders have excellent performance, panoramic view, high reliability, high comfort, high maintenance, high versatility, perfect shape and other technical features.
Main performance highlights
High reliability: the average overhaul period of the engine is ≥15000h; the hydraulic components PERMCO, HUSCO, MICO; the double-variable assembly is not opened for 10,000 hours; the rear axle assembly is a heavy-duty bearing reinforced chain.
High reliability: Roll-type maintenance-free tooling, large-scale outer diameter 1355mm bearing; box-type structure, minimum section size 270 × 340; 250 × 82 stringer and 990mm articulated height.
High comfort: high quality interior, texture, top grade 5.8m2 glass, panoramic view, 80.8 decibel low noise cab, much lower than the national 85 decibel standard value; ergonomic control system, 22Nm operation Force, labor-saving fatigue direction tilting adjustment range of the machine column 25 °, the operating attitude is free to adjust, air conditioning three-dimensional air supply, left and right 4 direct blowing large air outlet, around the surrounding six small air outlets, rapid temperature adjustment, multi-function central large dashboard, Separate from the steering column to avoid steering the steering wheel.
Five-column cab: Five pillars, that is, the main frame support structure of the cab is five pillars, which is different from the six-column structure of the current industry grader application, and is the first in the industry. The additional traction frame swing adjustment mechanism of the blade lifting cylinder is another independent innovation to enhance the control field of view. It makes the lifting cylinder behind the A-pillar of the cab, which makes the operator's view of the front wheel more open and safer.
Five-column cab, innovative work equipment adjustment mechanism, new engine hood, comprehensive product vision
Panoramic view
Ergonomic control system
High maintenance: the overall front hood, oversized 50° open angle, the cabin maintenance space is wider and lower fuel tank, the fuel outlet is only 1.1 meters above the ground, standing on the ground to refuel, convenient and safe 350L large-capacity fuel The box meets the needs of continuous operation throughout the day and reduces the frequency of fueling.

The cabin maintenance space is more open, the low fuel tank, the fuel inlet is only 1.1 meters above the ground, standing on the ground to refuel
Open frame articulated structure, maintenance personnel can directly access the gearbox and main hydraulic components
The side panel of the frame under the cab is detachable, and the internal hydraulic components and piping are unobstructed.
High maintenance : no threshold design, easy to clean, convenient reverse battery refueling battery negative switch, engine oil sump remote drain.
High-end configuration - ZF gearbox
High-end configuration - scrolling work unit
The perfect range of graders: beautiful appearance, high quality interiors, family style, neat piping.
From September 20th to 23rd, 2017, CLG4180D officially appeared at the Beijing Construction Machinery Exhibition (BICES), and won the Platinum Award for the highest award for innovative products.
Liugong D series grader with excellent performance, panoramic view, high reliability, high comfort, high maintenance, high versatility and perfect shape has won the attention and praise of the users. The D series grader will be the best helper for users to get rich, and will create the most value for customers.
