SEM 922F Motor Grader

Features:

1. Efficient, Reliable, and Thoughtful

• The SDEC engine meets China Nonroad Stage IV emission requirements and adds an ECO mode for greater energy efficiency and environmental protection. The optimized axle load ratio improves traction performance. • Uses internationally renowned variable displacement piston pump with PPPC (Proportional Priority, Pressure Compensated) control valve for on-demand power distribution, 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 vehicle operating noise, and enhancing overall performance. • Standard moldboard float function reduces work difficulty and operator fatigue, effectively improving construction efficiency. • Upgraded air dryer and air reservoir optimize braking performance and enhance brake system safety. • Large-diameter plastic fan delivers high airflow and effective cooling, ensuring continuous stable machine operation with lower noise for improved cab 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 inner sides of the front wheels as well as the positions of the drawbar, circle, and moldboard for safe and accurate operation. • Load-sensing hydraulic system provides precise cylinder speeds for easy fine grading and accurate control. • Electro-hydraulic controlled seven-position linkage allows automatic pin changing with one touch for high work efficiency. Different pin positions enable better adjustment of the moldboard angle relative to the ground for special applications. • Joystick layout follows Caterpillar's industry-leading standards with appropriate travel and spacing, requiring low effort, allowing the operator to handle multiple joysticks with one hand. • Spacious cab with mechanical suspension seat, standard high-capacity air conditioning, and multiple vents maximize operator comfort. • Front-to-back adjustable multifunction instrument panel with a new non-glare dashboard meets ergonomic requirements, enhancing the driving experience.

3. Robust and Durable for Peace of Mind

• Flanged box-section frame ensures durability under continuous high-intensity operations, extending structural component service life. • Front frame features continuous upper-and-lower plate structure with CAE global optimization for consistent strength and high rigidity. • The drawbar uses an A-frame structure made of two square tubes, providing excellent durability and strength with a long service life and low failure rate. • Caterpillar-manufactured rear axle with four planetary gear final drives for greater load-bearing capacity. • Standard reinforced transmission guard provides full protection for the transmission and DEF tank. • Radiator is mounted with floating vibration-absorbing mounts for reliability under rough, bumpy conditions. An optional 50°C high-ambient package is available for hot regions.

4. Easy Maintenance for Added Care

• Detachable drawbar ball joint for easy replacement; the ball joint can be adjusted for wear via shims, reducing user maintenance costs. • Seven-position linkage holes come standard with replaceable bushings for good maintainability, reducing service time and costs. • External caliper disc brakes provide short stopping distance and effective braking. Brake pads are common with SEM Wheel Loaders for easy replacement and high reliability. • Molded engine hood with large left and right doors facilitates easy maintenance and service. • Rear axle and tandem housing bearings are grease-free, and chains are adjustment-free, extending maintenance intervals and saving time, money, and effort. • Front and rear wheel rims are universal for interchangeability between front and rear wheels, improving machine availability.
