SEM 920F Motor Grader

Features:

1. Efficient, reliable, and thoughtfully designed

• The SDEC engine meets China Nonroad Stage IV emission requirements and features an added ECO mode for greater energy efficiency and environmental friendliness. The optimized axle load ratio delivers superior tractive performance. • The internationally renowned variable displacement piston pump and PPPC (proportional priority, pressure compensation) control valve distribute power on demand, reducing energy loss and heat generation in the hydraulic system. Proportional flow distribution enables simultaneous multi-function operations for high construction efficiency. • The variable displacement piston pump is directly connected to the transmission, improving drive efficiency, reducing working noise, and enhancing overall machine performance. • Standard blade float function reduces task difficulty and operator fatigue, effectively boosting construction efficiency. • Upgraded air dryer and air reservoir optimize braking performance and enhance braking system safety. • The large-diameter plastic fan delivers high airflow and effective cooling, ensuring continuous and stable machine operation, while reducing noise for improved cab comfort.

2. Effortless operation for enhanced comfort

The cab is positioned on the front frame for excellent visibility. Even during articulation, the operator can clearly see the inner front wheels, drawbar, circle, and blade position, ensuring safe and accurate operation. • The load-sensing hydraulic system provides precise cylinder speeds, enabling easy fine grading and accurate control. • The electro-hydraulic seven-hole linkage allows one-touch pin changes for high work efficiency. Repositioning the pin holes optimizes blade-to-ground angle for special applications. • Inheriting Caterpillar's industry-leading joystick layout with optimal stroke and spacing, the controls require minimal effort, allowing single-hand operation of multiple levers. • The spacious cab features a mechanical suspension seat, standard high-capacity air conditioning, and multiple vents to maximize operator comfort. • The front and rear adjustable multifunctional instrument panel, with a new non-glare dashboard, meets ergonomic requirements and enhances the driving experience.

3. Rugged and durable for peace of mind

• The flanged box-section frame ensures durability under continuous heavy-duty operation, extending the service life of structural components. • The front frame adopts a continuous upper and lower plate structure with CAE global optimization, ensuring consistency and high strength. • The drawbar is an A-frame constructed from two square steel sections, providing excellent durability, strength, long service life, and low failure rates. • The Caterpillar-built rear axle with four-planet final drives offers greater load-bearing capacity. • Standard reinforced transmission guard provides comprehensive protection for the transmission and urea SCR aftertreatment tank. • The radiator is mounted with floating vibration-absorbing pads to ensure reliability under rough operating conditions; a 50°C high-ambient-temperature package is available for hot regions.

4. Easy maintenance for added convenience

• The detachable drawbar ball joint can be easily replaced, and the clearance (via shims) can be adjusted according to wear, reducing user maintenance costs. • The seven-hole linkage comes standard with replaceable bushings, improving serviceability and reducing service time and cost. • External caliper disc brakes provide short stopping distance and excellent braking performance. Brake pads are interchangeable with those of SEM Wheel Loaders for easy replacement and high reliability. • The molded engine hood features large left and right doors for convenient maintenance and service access. • The rear axle and tandem housing bearings are pre-lubricated and require no grease, and chains are adjustment-free, extending maintenance intervals to save time, money, and effort. • Front and rear wheel rims are universalized for interchangeability, maximizing availability.
