SD32 Crawler Bulldozer Technical Specifications | 37,200kg Heavy-Duty Bulldozer for Mining and Earthworks

The SD32 crawler bulldozer is a high-tonnage, heavy-duty piece of construction machinery with an operating weight of 37,200 kg. Featuring robust power and a reliable undercarriage structure, it is widely used in heavy-duty applications such as mining earthworks, site leveling for infrastructure, and excavation for water conservancy projects.

SD32 Bulldozer Power System Configuration

The machine is equipped with a Cummins NTA855-C360S10 water-cooled, direct-injection, turbocharged diesel engine. It delivers a rated power of 257 kW and a maximum torque of 1,440 N·m. With ample power reserves, it handles heavy-load dozing and hard-soil breaking tasks with ease while maintaining stable fuel economy.

Transmission and Undercarriage Performance

The SD32 features a single-stage, single-phase, three-element torque converter, a planetary gear powershift transmission, and wet-type steering clutches and brakes. Its travel system utilizes an oscillating equalizer beam with a "figure-eight" structure; the large track-to-ground contact area ensures excellent mobility on muddy terrain and rocky mining surfaces. It achieves a maximum forward speed of 11.5 km/h and a maximum reverse speed of 13.5 km/h.

Blade and Ripper Work Equipment

This model supports various blade options, including straight-tilt, angle, and semi-U blades, with capacities of up to 11.9 m³. It can be fitted with a three-shank or single-shank ripper capable of a maximum ripping depth of 960 mm, allowing it to break through hard soil layers and weathered rock to meet requirements for mining overburden removal and site clearing.

Application Scenarios

The SD32 heavy-duty bulldozer is ideal for large-scale projects, including overburden removal in mines, site leveling for open-pit mines, roadbed excavation for highway infrastructure, and dam or water conservancy construction.

The machine features a robust and durable structure and a stable hydraulic system, making it a mainstream bulldozer for large-scale earthmoving projects in China.
