Used CAT 140G Motor Grader Introduction
The Used CAT 140G Motor Grader is a legendary classic heavy-duty grader in Caterpillar’s early mature product line, famous worldwide for ultra-reliable mechanical structure, rugged durability, strong terrain adaptability and ultra-low maintenance difficulty. As a time-tested staple model, the CAT 140G is equipped with Caterpillar’s classic original mechanical engine and stable fixed-displacement hydraulic system. It features pure mechanical control, simple operation and extremely low failure rate, perfectly suitable for rural road maintenance, municipal leveling, farmland renovation, mine auxiliary construction and various harsh field working scenarios. It is the most cost-effective vintage CAT grader favored by global engineering contractors for long-term stable operation.
Basic Machine Overview
This pre-owned CAT 140G motor grader is in excellent well-maintained working condition with standard practical configuration and mild mechanical wear after regular maintenance. The whole machine retains original factory body structure and paint condition, without frame deformation, structural cracking, major collision damage and persistent oil leakage. All core key components are original CAT factory assemblies, including the classic CAT original mechanical engine, mature manual power-shift transmission and reinforced heavy-duty rear tandem drive axles. With a stable operating weight of about 16.5 tons and a standard 3.7m heavy-duty wear-resistant moldboard, the machine features solid body rigidity and strong blade traction. It supports long-time uninterrupted heavy-load operation, and can stably adapt to muddy, gravel, rugged and other complex harsh construction environments.
Core Power & Fuel Efficiency Performance
The CAT 140G is equipped with Caterpillar’s classic original mechanical diesel engine, adopting pure mechanical fuel supply and power output structure without complex electronic control modules. The engine outputs stable and sufficient torque reserve, with strong low-speed climbing performance and overload resistance, fully meeting heavy-duty operations such as road substrate trimming, ditch excavation, slope shaping and bulk earthwork spreading. The mature and simple power system structure avoids electronic failure faults, with extremely high operational stability. With optimized fuel combustion technology, it maintains balanced and economical fuel consumption under daily working and heavy-load conditions. Its biggest advantage is long-term stable power output and greatly reduced on-site downtime risk, adapting to various unstable working conditions in remote construction areas.
Hydraulic System & Working Performance
The used CAT 140G adopts Caterpillar’s classic mature fixed-displacement hydraulic system, with sensitive and responsive overall hydraulic control. The lifting, tilting, side shifting and rotating actions of the moldboard are smooth and coherent, with uniform force and high leveling accuracy. The hydraulic circuit is simple and durable, with low failure rate and convenient daily inspection and maintenance. The matched thickened reinforced heavy-duty moldboard has super strong cutting force and soil pushing capacity, realizing one-time precise leveling and efficient earthmoving. The pure mechanical operating mechanism has clear and simple operation logic, low operation threshold, and is not affected by temperature and working environment. It can maintain stable working efficiency in high-temperature, dusty and harsh field environments for a long time.
Durable Structure & Safety Design
The main frame, rotating circle and moldboard of the CAT 140G are all made of thickened high-strength integral steel plates, with overall reinforcement treatment at key stress-bearing parts. The whole machine has strong impact resistance, wear resistance and structural anti-fatigue ability, and is not easy to deform after long-term heavy-load operation. The reinforced heavy-duty chassis and solid integral drive axle greatly improve the overall load-bearing and anti-skid performance, adapting to complex road surfaces such as gravel roads, muddy roads and unhardened construction sites. The practical open/closed cab has a wide field of vision, which can clearly observe the moldboard and construction status, effectively reducing operation blind areas. Equipped with reliable mechanical braking system and stable walking control, it ensures safe and stable operation in long-term high-intensity construction scenarios.
Application Scenarios & Core Advantages
The CAT 140G motor grader is widely used in rural road construction and daily maintenance, municipal site leveling, open-pit mine auxiliary leveling, farmland land consolidation, highway slope trimming, ditch excavation and large-scale earthwork projects. After decades of market and field verification, this classic model has irreplaceable core advantages: pure mechanical structure, zero complex electronic faults, ultra-low failure rate, extremely convenient maintenance and global universal spare parts. Compared with new electronic-controlled models, it has lower daily maintenance costs, stronger site adaptability and higher fault tolerance rate. The whole machine has stable performance, can be put into construction immediately after simple commissioning, and has extremely high cost performance, which is the preferred classic model for old construction teams, remote engineering projects and budget-friendly equipment procurement.
