components of a bulldozer

The main components of a bulldozer include the chassis, blade, track and rollers, engine, and hydraulic system, all made from high-strength alloy steel to withstand weight and operational pressure. Blade lengths typically range from 3 to 5 meters, heights from 1 to 2 meters, and can endure ground pressures up to 120 tons. The chassis is welded steel with thicknesses of 25 to 40 millimeters, and steel tracks 450 to 700 millimeters wide can withstand tensile forces up to 200 kN.

The hydraulic system includes high-pressure pumps up to 250 bar, cylinders for blade movement, and steering. Diesel engines deliver 150 to 600 horsepower with cylinder capacities between 5 and 20 liters. Mechanical and hydraulic components are inspected using non-destructive testing NDT and dimensional checks up to 0.1 millimeters to ensure service life exceeding 15,000 hours.
