Every dozer fleet relies on robust workhorses, versatile and powerful machines that stand the test of time. This dozer has been meticulously designed from the ground up to fulfill that pivotal role. The Tier 4 Final engine, coupled with an electronically controlled hydrostatic transmission, ensures remarkably low fuel consumption without compromising power. Its standard parallel link undercarriage system, featuring rotary bushings, is engineered for extended wear life and reduced repair/maintenance costs. With economy and power modes, along with a high engine rpm H mode, operators can effortlessly maintain ground speed, especially when handling heavy loads.
- Streamline the onboarding of new operators
- Accelerate the transition from mass excavation to finished grading
- Seamlessly integrate 3D design data into the machine’s operation
- Empower operators to work efficiently, pass after pass
Product Features and benefits:
Operates with Adaptive Learning Capabilities
Through the implementation of proactive dozing control, even operators with limited experience can efficiently execute cutting or stripping tasks on existing terrain. The dozer systematically assesses the traversed terrain, utilizing gathered data to strategically plan subsequent passes. This feature has the potential to enhance productivity by up to 60%, surpassing the capabilities of previous generations.
Automated Spreading of Fill Material
The lift layer control facilitates the automatic spreading of fill material by operators at the touch of a button, utilizing terrain data collected by the dozer for planning subsequent passes. This functionality allows for a potential doubling of production output and ensures the creation of consistent layers, promoting compaction quality.
Precise Material Leveling in Challenging Conditions
The tilt steering control automatically adjusts the blade, maintaining a straight path during rough dozing and significantly reducing operator steering input by up to 80%.
Efficient Creation of Temporary Design Surfaces
Operators have the capability to promptly create temporary design surfaces with the press of a button. This, in conjunction with other IMC 2.0 functions, enables the crew to initiate automated stripping or spreading tasks while awaiting the finish grade model.
Skill Gap Mitigation
Machine logic empowers the dozer to continually learn from the terrain, making calculated decisions for subsequent passes. The Intelligent Machine Control system plays a pivotal role in mitigating the skill gap between novice and seasoned operators.
Sophisticated Machine Control Features
In specific scenarios such as auto stripping, rough dozing, spreading, and advanced finish grading, operators can opt for nearly 100% machine control auto usage. This functionality is achievable even without a 3D model, showcasing the advanced capabilities of the system.
Adaptive Learning from Operator Inputs
Automatic functions equip the dozer with the ability to learn from the operator’s blade inputs, fostering increased adaptability, ease of operation, and reduced dependence on manual inputs.
Superior Blade Response for Precision Grading
To ensure unparalleled grading performance, the Intelligent Machine Control (IMC) system allows the dozer to anticipate grade transitions and adjust the blade angle accordingly.
