Spare parts are widely compatible, ensuring easy replacement and seamless integration.
DT22S Crawler Bulldozer Overview
The DT22S Crawler Bulldozer Wetland Edition is a hydro-mechanically driven crawler bulldozer engineered for soft-ground and low-bearing-capacity environments. Designed for wetland, swamp, and muddy terrain operations, it delivers stable traction, controlled ground pressure, and reliable earthmoving performance in challenging natural conditions. As a specialized configuration within the series, the DT22S Crawler Bulldozer is optimized for efficient operation where conventional equipment may struggle.
Primary Application Scenarios
The DT22S Crawler Bulldozer is developed for engineering projects that require stable performance on soft, unstable ground conditions.
Wetland and marsh construction
It is primarily used in wetlands, marshes, and muddy terrain with limited load-bearing capacity. Its design ensures stable movement and operational reliability in low-ground-strength environments.
Water conservancy and environmental engineering
The machine is suitable for river dredging, embankment construction, tidal flat reclamation, and ecological restoration projects, providing consistent performance in water-related infrastructure development.
Foundation earthworks
In general infrastructure projects such as highways, railways, and airports, the DT22S Crawler Bulldozer supports dozing, excavation, and backfilling operations in soft soil conditions.
Wetland Mobility and Ground Adaptation
The machine is equipped with extra-wide wetland track shoes measuring 910 mm, combined with a low ground pressure design of approximately 35.2 kPa. This configuration significantly improves flotation performance and prevents sinking in muddy or waterlogged terrain.
The crawler system ensures stable movement and strong traction, allowing the machine to operate efficiently in complex wetland environments.
Powertrain and Transmission Performance
The DT22S Crawler Bulldozer features a high-efficiency turbocharged diesel engine paired with a hydraulic torque converter and power-shift transmission system. This integrated configuration ensures smooth power delivery and stable output under varying load conditions.
The powertrain is designed to maintain reliable performance in soft ground and high-resistance environments, supporting continuous heavy-duty operations.
Operator Control and Intelligent Monitoring
The control system adopts an ergonomically optimized lever layout combined with a servo-assisted mechanism, providing light and responsive operation.
An integrated injection-molded instrument panel includes automatic fault detection and system monitoring functions. This enhances operational awareness while improving maintenance efficiency and reducing downtime.
Working Efficiency and Structural Design
The DT22S Crawler Bulldozer is equipped with a large-capacity straight-tilt blade and a raised chassis structure. This design increases lifting height and working range, improving grading efficiency in wetland environments.
The structural layout is optimized to maintain stability while enhancing adaptability across soft and uneven terrain conditions.
