| Features:
SD42-3 is one of the most powerful track-type bulldozers in China. Mainly used in large mine projects, the SD42-3 can be adapted to tough working conditions. 1. Great tractive force and good adhesion property. 2. More reliable transmission, higher transmission efficiency, simpler structure and more convenient maintenance, compared to hydraulic bulldozer. 3. Powerful engine, low oil consumption and low noise, accommodating various operating conditions with an elevation below 4000 m. 4. Travel system with swing rocker beam (equalizer). The rocker beam is designed with semi-rigid suspension, which may ensure operating stability and smoothness of the complete machine, but also may effectively reduce the impact of the operating surface to the transmission system and cab, and improve safety and comfort. 5. Properly matched transmission ratio of transmission system with engine to make full use of engine power. 6. Central lubricating system provided for bad operating conditions. Main features:
● Single-hand, electronic-control gear shift and steering systems;
● Working device controlled by PPC proportional pilot valve;
● K suspension drifting travel system;
● Global intelligent service system;
● Central pressure measurement, central lubrication, and automatic track tensioning; | ITEM | UNIT | SD42-3 | | L×W×H (Ripper not included) | mm | 9630×4315×3955 (Ripper included) | | Operating weight (Ripper not included) | t | 53 (Ripper included) | | Engine | - | Cummins KTA19-C525 | | Rated power | kW/rpm | 310/2000 | | Gradeability | ° | 30 | | Blade type | - | Semi-U blade | | Blade width | mm | 4315×1875 | | Dozing capacity | m3 | 16 | | Ma× drop below ground of blade | mm | 700 | | Lift height of blade | mm | 1545 | | Ripper type | - | Single ripper | | Ripping depth of ripper | mm | 1400 | | Lifting height of ripper | mm | 1130 | | Number of carriers (each side) | - | 2 | | Number of track rollers (each side) | - | 7 | | Number of track shoes (each side) | - | 41 | | Width of track shoe | mm | 610 | | Track gauge | mm | 2260 | | Ground length and ground pressure | mm/MPa | 3560-0.123 | | Pitch | mm | 260.35 | | Forward speed | km/h | 0–3.7 | | 0–6.8 | | 0–12.2 | | Reverse speed |

The power shift transmission not only ensures smooth power shift, but also reaches target speeds and carries out directional transfers with a single control lever;
The wet steering clutch and brake can extend service life. They work interactively, ensuring quick and flexible steering operations;
The single control lever can control all blade actions;
The drift sealing in the drive wheel, track roller and carrier roller can prevent dust from entering the track system, as well as lubricant leakage, thereby ensuring a long service life;
The hexahedron cab features wide visibility, and the insulation materials in the cab can reduce noise and vibrations;
The spin type fuel filter and dust separator, the air filters and the other filtration devices can prolong work time and reduce service time;
The comfortable cab seat can adjust upward and downward, forward and backward, meeting any positional needs the operator may have;
Side engine operation and the combination of a drive/brake operation system and foot brake makes overall operation of the bulldozer more rapid and convenient.
