Brand: CAT (Caterpillar) – A top-tier American heavy machinery brand with a presence in over 200 countries, renowned for cutting-edge engineering, extreme durability, and all-weather reliability. Its motor grader series has long dominated global large-scale infrastructure projects, becoming synonymous with precise grading and efficient operations.Model: 140K – An upgraded flagship mid-size motor grader, the benchmark iterative product of CAT’s 140 series. Designed for medium-to-large intensity precision grading, roadbed finishing, and site development, it integrates enhanced power, intelligent control, and long-term durability. It meets the needs of high-end international projects such as highway construction, mining site preparation, and large-scale park development.
Equipped with CAT’s exclusive C7.1 ACERT diesel engine, featuring advanced electronic fuel injection technology. Its power output is over 10% higher than the previous generation, stably handling heavy grading of complex materials like compacted soil, weathered rock, and gravel. Paired with the brand’s patented “Load-Sensing Hydraulic System,” power is distributed on demand to avoid energy waste. The standard ECO Mode further optimizes fuel consumption, significantly reducing operating costs for long-term overseas projects with excellent continuous operation endurance.
Inheriting the rugged DNA of CAT heavy machinery, the mainframe is integrally formed from high-strength alloy steel. Stress-concentrated areas undergo triple reinforced welding, with torsion and impact resistance far exceeding industry standards. The moldboard is made of wear-resistant hardened steel, and the cutting edge is reversible—no need for full replacement after wear, drastically reducing accessory costs. The undercarriage is equipped with reinforced tandem drive axles and puncture-resistant heavy-duty tires, with optimized ground pressure design. It maintains stable passability and service life even in harsh terrains like deserts, mud, and rocky areas.
Comes standard with CAT’s next-generation “AccuGrade GPS/Laser Precision Grading System,” achieving centimeter-level operation accuracy. Complex slopes and curved surfaces can be graded without manual staking. The cab adopts a suspended shock absorption design, paired with an adjustable air-suspension seat and lumbar support, effectively filtering operational vibrations and reducing fatigue during 12+ hour shifts. Panoramic explosion-proof glass eliminates blind spots, and a multi-functional touchscreen display integrates real-time data on the engine, hydraulic system, and operation precision. The control levers feature a humanized layout, allowing new operators to master quickly.
Maintenance design is fully optimized: the engine hood adopts a side-opening structure, with filters, oil fill ports, hydraulic inspection points, and other components centrally arranged. Daily maintenance can be completed without climbing or disassembling complex parts. CAT’s global spare parts network covers over 190 countries and regions. Common accessories (such as moldboard cutting edges and hydraulic filters) are delivered quickly from local warehouses, even reaching remote areas within 72 hours. Core components (engine, hydraulic system) come with a global warranty, and a professional technical team provides 24/7 online diagnosis and on-site repair support.
CAT’s iconic tough design, with sharp body lines and a balanced proportion between the mainframe and working devices, highlighting strong operational capabilities. The exterior is coated with corrosion-resistant and UV-protective paint, withstanding multiple climatic environments such as tropical high temperatures, cold region low temperatures, and coastal high salt spray. It maintains good condition even after long-term outdoor operations.
The large-capacity moldboard (standard width 3.7 meters, optional 4.3-meter extended version) features an optimized curved design for efficient material pushing and spreading. The reversible wear-resistant cutting edge extends service life by 50% compared to conventional designs. The hydraulic scarifier (standard configuration) with multiple teeth can easily break up hard soil and weathered rock, improving subsequent grading efficiency. All working parts adopt sealed lubrication to prevent dust and sand intrusion.
The C7.1 ACERT engine operates smoothly with low noise and meets global emission standards (Tier 3/Tier 4 Final) for cross-border use. CAT’s proprietary hydraulic system delivers precise and responsive control of the moldboard, scarifier, and steering system, ensuring stable performance even during high-intensity continuous operations. The integrated hydraulic oil cooling system effectively prevents overheating in high-temperature environments.
The spacious cab features sound insulation and thermal insulation design, with an internal noise level below 75 decibels. The air-suspension seat with lumbar support is adjustable in multiple directions, adapting to operators of different body types. The large touchscreen display supports multi-language switching and real-time monitoring of operation data. Intuitive joysticks reduce operating effort, and the rearview camera (standard) and 360° panoramic monitoring system (optional) enhance operational safety. The automatic climate control system maintains a comfortable temperature in extreme weather.
With its powerful performance and precise control, the 140K is suitable for a wide range of international large-scale projects:
- Highway & Road Construction: High-precision grading of expressway subgrades, finishing of asphalt/concrete surfaces, construction of rural road networks, and slope shaping for road drainage.
- Mining & Site Preparation: Leveling of open-pit mining sites, construction of transport roadbeds in mines, and site clearing and leveling for industrial plants/airports.
- Water Conservancy & Agricultural Projects: Shaping of irrigation canals, leveling of large farmland, construction of flood control embankments, and land reclamation.
We provide end-to-end support to simplify international procurement:
- Transparent Inspection Reports: Detailed documents covering mechanical performance (engine power, hydraulic pressure), moldboard alignment accuracy, undercarriage wear, and safety component checks—with videos showing the machine in real grading operations.
- Customs Clearance Assistance: Expert help with preparing import documents (certificate of origin, emission compliance report, commercial invoice) and adapting to local regulations (e.g., heavy machinery import tariffs, safety certifications, environmental standards).
- Tailored Logistics Solutions: Flexible shipping options (ro-ro shipping for whole-machine transport, bulk shipping for spare parts) with anti-rust, anti-collision packaging for vulnerable components like the moldboard and scarifier. Real-time cargo tracking is provided until delivery to your construction site, with on-site assembly, commissioning, and operation training available if needed.
The 140K represents CAT’s engineering excellence, combining power, precision, and durability in one machine. It addresses the pain points of high-intensity, high-precision projects overseas—reducing operational costs, minimizing downtime, and improving project efficiency. Backed by CAT’s unparalleled global service network, it provides reliable support for international projects in any region. For overseas teams seeking a high-performance, low-risk motor grader, the 140K is the ultimate choice.
