Crawler Bulldozer,Bulldozer

The bulldozer has the advantages of advanced structure, labor-saving operation, low fuel consumption, convenient use and maintenance and reliable quality. It can be equipped with various devices, such as traction frame, coal-pushing shovel, ripper and capstan. The bulldozer is applicable to various working conditions. The design of instrument assembly is simple and easy to understand, which is used to monitor coolant temperature of the engine, oil pressure, oil temperature of transmission system and electrical instrument. The visual field of cab is wide. The bulldozer features good working adaptability, working efficiency and convenient maintenance. The Bulldozer is track-type model which utilizes semi-rigid suspension, mechanical drive and hydraulic control. It can be used in road building, hydro-electric construction, field modification, port and mine development and other constructions.
