SD46

SD46-6 Tracked Bulldozer

The SD46-6 tracked bulldozer features a PPC pilot proportional valve control system for its working implements, a K-type suspended floating undercarriage system, a global intelligent service system, and ROPS (Roll-Over Protective Structure) and FOPS (Falling Object Protective Structure) devices. Boasting an advanced structural design, exceptional adaptability to various working conditions, and high operational efficiency, this machine is particularly well-suited for earthmoving, rock stripping, and similar heavy-duty tasks in mining and construction projects.

Power System

Equipped with a Cummins KTA19-C525 turbocharged diesel engine, delivering robust power output while ensuring high efficiency and energy conservation.

The cylinder block and cylinder head feature an integrated design, effectively preventing water and oil leaks.

Compared to similar products in its class, the number of components has been reduced by over 25%, resulting in a significantly lower failure rate, reduced maintenance costs, and a time savings of more than 50% on routine maintenance.

Transmission System

Utilizing a reliable power-shift transmission and a planetary final drive structure, the system ensures highly efficient power transmission, exceptional durability, and high operational efficiency.

It is capable of optimizing fuel economy by automatically adjusting to changes in external load conditions.

The hydraulic components are designed to absorb impact loads generated by the transmission system, thereby extending the service life of the engine by 1.5 to 2 times.

The transmission features multi-plate clutches, hydraulic engagement, and forced lubrication, while the final drive utilizes spiral bevel gears and splash lubrication.

Working Hydraulic System

It employs newly designed hydraulic cylinders; seals for critical components and hydraulic hoses are all imported products.

This ensures a longer service life and higher reliability, while the externally mounted working valves make maintenance and servicing more convenient.

Electrical System

Imported instrumentation provides more precise and intuitive data displays. It enables electronic monitoring and over-limit alarms for key operating parameters—such as oil temperature, oil level, and water temperature—thereby ensuring higher reliability.

Structural Components

The main frame features a full box-section structure, constructed from high-performance materials and high-strength castings. It possesses exceptional resistance to impact loads, bending, and torsion, enabling the equipment to perform high-intensity, continuous operations under severe working conditions. High-quality welds ensure the integrity of the main frame throughout its entire service life.

Undercarriage System

The K-type suspension floating drive system and articulated undercarriage structure effectively mitigate the impact of shock loads on the transmission system, thereby enhancing the vehicle's traction performance and service life.

An advanced shock absorption system effectively absorbs impact loads, improving overall vehicle stability under complex working conditions.

The sealed and lubricated track chains feature a master-link design, offering a long service life and facilitating easy assembly and disassembly.

Operating Environment

The cab features an aesthetically pleasing design, a spacious interior, and an expansive field of view. The addition of shock absorbers reduces vibration, and—combined with the air conditioning system—it ensures a safer and more comfortable operating environment for the driver.

The dashboard is integrally injection-molded, featuring a logical and aesthetically pleasing layout for electrical components, instrumentation, and the air conditioning system.

Designed with ergonomics in mind, the driver's seat and armrests can be easily adjusted vertically. Controls for shifting, steering, and acceleration are positioned on the left side, while controls for the work implements are located on the right. Utilizing a PPC pilot control system, operations are light and agile, effectively reducing operator fatigue.

Work Implements and Attachments

The front work implement comes standard with a semi-U blade. Constructed from high-strength box-section structures and high-performance materials, the blade ensures powerful cutting force and exceptional durability, enabling it to handle a wide variety of complex operating environments. The ultra-large 16 m³ capacity blade is an ideal and highly efficient tool for earthmoving operations and the loading and transport of loose materials.

The rear work implement consists of an angle-adjustable single-shank ripper, delivering superior penetration power and high-strength performance.

Safety Features

Safety warning lights, a reverse alarm buzzer, a horn, a reliable braking system, and highly visible machine livery work together to effectively safeguard personnel in the surrounding area and enhance safety during all-weather operations. Additionally, a seatbelt, numerous grab handles located throughout the machine, and safety decals provide comprehensive safety protection for the operator.

Side guards effectively protect the engine and radiator, preventing blockage and damage caused by external debris while simultaneously enhancing the machine's overall aesthetic appeal.

The standard-equipped antifreeze raises the boiling point and lowers the freezing point of the coolant, effectively preventing scale buildup in the engine and radiator to facilitate optimal engine cooling and protection.

Furthermore, an optional ROPS (Roll-Over Protective Structure)—which also incorporates FOPS (Falling Object Protective Structure) functionality—is available to prevent operator injury in the event of an accident.

Maintenance and Service

Prominently placed decals provide clear reminders to users regarding proper maintenance procedures, while the battery is of a maintenance-free type. The open-style engine hood allows for full exposure of internal components, facilitating easy inspection and repair.

The equipment features high reliability and a long Mean Time Between Failures (MTBF), while its operating and maintenance costs are lower than those of other brands.

Shantui’s comprehensive service network—combined with its prompt, attentive, and thoughtful support—serves as a reliable guarantee for your peace of mind during operation; furthermore, the enduring quality of our products fully meets your expectations for Shantui equipment.
