Shantui SD22 Bulldozer Overview

The SD22 bulldozer is a medium-sized crawler bulldozer that offers a good balance between power, fuel efficiency, and operational capacity. It's widely used in heavy earth-moving tasks such as soil pushing, grading, road construction, and clearing land. It is equipped with a reliable diesel engine and has a relatively simple design, which makes it easier to maintain and repair.

Key Features of the Shantui SD22 Bulldozer:

• Engine Power: The SD22 is typically powered by a Cummins NTA885-C360 engine (or sometimes other engines depending on the model year and region), providing an output of around 220 horsepower (164 kW). This engine provides sufficient power for most medium-to-heavy tasks.

• Hydraulic System: The SD22 bulldozer uses a hydrostatic transmission system, which allows for better speed control, smoother operation, and reduced mechanical stress.

• Track and Undercarriage: The SD22 is equipped with a heavy-duty undercarriage system, offering enhanced traction and stability on difficult terrain. The tracks are designed to distribute weight evenly, reducing ground pressure for improved performance in soft soil and sandy areas.

• Blade and Ripper: The SD22 can be equipped with various types of blades, including a semi-U blade for general earth-moving and a straight blade for precise grading. Some models may also come with a ripper attachment, which is useful for breaking compacted soil or rock.

• Operator Comfort: The SD22 features an ergonomic operator’s cabin with a high level of visibility, which helps to reduce operator fatigue. The cabin is often equipped with air conditioning and adjustable seating for comfort during long working hours.
