Bulldozer DFY-3

The bulldozer has the advantages of advanced structure, labor-savingoperation, low fuel consumption, convenient use and maintenance and reliablequality. It can be equipped with various devices, such as traction frame,coal-pushing shovel, ripper and capstan. The bulldozer is applicable to variousworking conditions. The design of instrument assembly is simple and easy tounderstand, which is used to monitor coolant temperature of the engine, oilpressure, oil temperature of transmission system and electrical instrument. Thevisual 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, mechanicaldrive and hydraulic control. It can be used in road building, hydro-electricconstruction, field modification, port and mine development and otherconstructions.
