SEM 919F Motor Grader

Features:

1. Efficient, Reliable, and Thoughtful • The SDEC engine meets China National Stage IV emission requirements for non-road machinery, with an added ECO mode for better energy efficiency and lower emissions. The optimized axle load ratio enhances tractive performance. • Internationally renowned brand variable displacement piston pump with PPPC (proportional priority, pressure compensation) control valves distributes power as needed, reducing energy loss and hydraulic system heat generation. Flow is proportionally distributed, allowing multiple combined operations simultaneously for high construction efficiency. • The variable displacement piston pump is directly connected to the transmission, improving transmission efficiency, reducing operating noise, and enhancing overall vehicle performance. • Standard blade float function reduces operational difficulty and operator fatigue, effectively improving construction efficiency. • Upgraded air dryer and air reservoir optimize braking performance and enhance braking system safety. • Large-diameter plastic fan delivers high airflow and effective cooling, ensuring continuous stable machine operation, with lower noise for improved operator comfort.

2. Easy Operation for Greater Comfort • The cab is mounted on the front frame, providing excellent visibility. Even during articulation, the operator can clearly see the inside of the front wheels, as well as the positions of the drawbar, circle, and blade, ensuring safe and accurate operation. • Load-sensing hydraulic system delivers precise cylinder speeds for easy fine grading and accurate control. • Electro-hydraulic controlled seven-hole linkage mechanism enables automatic one-touch pin changing for high work efficiency. By changing hole positions, the blade-to-ground angle can be better adjusted for special tasks. • Adopting Caterpillar's industry-leading joystick layout, with appropriate stroke and spacing and low operating effort, the operator can handle multiple levers with one hand. • Spacious cab with mechanical suspension seat, standard high-capacity air conditioning, and multiple air vents maximize operator comfort. • Front-and-rear adjustable multifunction dashboard with a new, non-glare instrument panel meets ergonomic requirements, enhancing the driving experience.

3. Sturdy and Durable for Peace of Mind • Flanged box-type frame structure ensures durability under continuous high-intensity operations and extends the service life of structural components. • The front frame features a continuous upper-and-lower plate structure, globally optimized with CAE for consistent strength. • The drawbar is an A-frame design made of two square tubes, offering excellent durability, strength, long service life, and low failure rate. • Caterpillar-manufactured rear axle with four-planet final drive arrangement provides greater load-bearing capacity. • Standard reinforced transmission guard provides comprehensive protection for the transmission and the DEF tank. • The radiator is mounted with floating vibration-damping pads to ensure reliability under rough, bumpy conditions. An optional 50°C high-temperature package is available for hot regions.

4. Convenient Maintenance with attentive care • The detachable drawbar ball joint is easy to replace, and the gap can be adjusted (via shims) based on wear, reducing maintenance costs for the user. • The seven-hole linkage is equipped with standard replaceable bushings in the holes for good serviceability, reducing service time and costs. • External caliper disc brakes provide short stopping distances and effective braking. The friction pads are interchangeable with SEM wheel loaders, making replacement easy and ensuring high reliability. • Molded engine hood with large left and right opening doors facilitates maintenance and service. • Grease-free lubrication design for rear axle and tandem housing bearings, and adjustment-free chain design extend maintenance intervals, saving time, money, and effort. • Standardized front and rear wheel rims allow interchangeability between front and rear wheels, increasing availability.
