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;

Details The extended track ensures low ground pressure, high reliability
and strong traction, contributing to precise operation;
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.
