G9138 is a high-speed, high efficiency, high precision and
versatile product developed by SDLG after full investigation of
market demands, which can complete the ground leveling and
trenching, slope scraping, bulldozing, snow discharge, loosing,
compaction, material distribution, mixing, etc., and is widely used
in highways, airports, defense engineering, mine construction, road
construction, water conservancy construction, farmland improvement
and other construction conditions.
1、Rear drive axle: it uses the large speed ratio heavy drive axle
to meet the low-speed finishing requirements, and is equipped with
the No-spin limited-slip differential to greatly improve the
dynamics and trafficability of the whole machine; the heavy roller
chain drive balancing box can swing by ± 15 °,
to ensure that that middle and rear wheels touch the ground at the
same time to significantly increase the overall traction and
flatness of the blade operation.
2、Circle turn system: it uses a dual cylinder + circle turn valve
structure, so that the dual drive gear is in engaged drive with the
rotary gear ring;therefore, there are more meshing teeth quantity,
low teeth stress and small abrasion; the cylinder has high
efficiency, and the blade is circle turn under loads, so that it
has high operation precision and high reliability.
3、Moveable blade control system: it is connected to the ear plate
with the front frame through the composite bearing, so it has high
impact resistance, wear resistance, low friction coefficient and
high reliability; the moving part applies the imported
lubrication-free and maintenance-free composite bearing and high
4、Gearbox: it is equipped with a YD13 power shift gearbox, which
can change the speed in six-forward and three-reverse to adapt to
the complex conditions.
5、Braking system: the standard single-loop fully hydraulic braking
system,brake valve,charge valve and other key elements apply the
mico products, which is safe and reliable, and the dual-loop fully
hydraulic braking system moduleis optional.
6、Frame: The front frame is in a box-type frame structure, so it
has high strength and high reliability; the rear frame is in a
frame structure made by welding of the box-type beam, and the
attachment device is easy to assemble so it has high reliability.
It is equipped with a Weichai engine, which is in good match with
the advance YD13 gearbox to achieve optimum performance and fuel
efficiency, so it is energy-saving and efficient.
1、Instrument panel: it uses the digital stepping instrument panel,
so it has high man-machine interaction and easy detection and
2、Multi-way valve: the multi-way valve is arranged in front of the
cab, which is easy to maintain.
