25T Cummins Engine Shantui bulldozer 220HP SD22 with rear ripper
Description:
Shantui SD22 series bulldozer adopts Shantui's patented
technologies, including central lubrication, central pressure
measurement, and automatic track tensioning technologies, and won
the sole national golden quality award in China's bulldozer
industry. With multiple working devices and cabs, this product can
meet the operation demands for diversified working conditions and
is an ideal high-efficiency machine for earth-moving operations and
bulk material handling.
1.Chongfa NT855-C280S10 engine features strong power and high
efficiency and energy-saving.
2.The high reliability power shift transmission, the stable
hydraulic torque converter, and two-stage spur gear final drive
feature high power transmission efficiency.
3.The engine can run normally and reliably under all load
conditions and all hot environments required by the user without
overheating.
4.It can realize the automatic diagnosis and whole-process
monitoring of the malfunctions. The integrally injection molded
instrument panel integrates the A/C, electric devices, and
instruments, featuring beautiful appearance and high grade.
5.The full box-type main frame with application of high performance
materials and high strength castings features high by carrying
capacity against impact load and bendingmoment and the high quality
welds guarantee the life cycle of the main frame.
6.The semi-rigid suspension traveling system increases the ground
area of tracks and improves the traction force of vehicle.
7.The ergonomically designed driver seat and armrests can be
adjusted easily in vertical and longitudinal directions. The
gearshift, steering, and accelerator controls are arranged on the
left side with the adoption of flexible shaft structure. The
working device controls are arranged on the right side with
adoption of servo control system to achieve lighter and more
flexible operations and relieve the operating fatigue.
8.The standard straight tilting blade features powerful cutting
force to handle diversified severe working environments and the
large single-shank ripper of adjustable penetrating angle can be
used for the ripping of clay and frozen earth as well as the
stripping of hard working faces, such as gravel and hardened salt
mine.
