What are the advantages of CAT 320D excavator?
1. Power and performance advantages
Powerful power system
Equipped with Caterpillar’s independently developed C6.4 diesel engine, the power can reach 135 horsepower (about 101kW), with stable power output, suitable for high-intensity operation scenarios (such as digging hard soil, crushing rocks, etc.).
Equipped with turbocharging and direct fuel injection technology, it has high fuel efficiency, which reduces fuel consumption while ensuring power and reduces operating costs.
Efficient hydraulic system
Adopting Caterpillar’s advanced hydraulic control system, the hydraulic pump has a large flow rate (about 240L/min), strong digging force (bucket digging force can reach 137kN), and improves work efficiency.
The action response is sensitive and the compound operation is smooth (such as digging + rotation at the same time), which is suitable for fine work or fast cycle operation.
2. Reliability and durability
Sturdy structural design
The body frame is made of high-strength steel, and key parts (such as boom, dipper, bucket) are thickened and reinforced, with strong impact and wear resistance, suitable for harsh working conditions (such as mining, heavy-load construction).
The chassis adopts heavy-duty tracks and reinforced rollers, with low ground pressure and good stability, while reducing track wear and extending service life.
Mature technical verification
As a classic model of Carter’s “D series”, the 320D has been verified by the market for a long time, and the core components (engine, hydraulic pump, control valve) have a low failure rate and a long maintenance cycle, which is suitable for long-term continuous operation.
The heat dissipation system is optimized, equipped with a large-size radiator and fan, which can maintain stable operation even in high temperature environments and reduce the risk of downtime.
3. Operation comfort and convenience
Humanized cab
The cab is spacious, with air conditioning and suspension seat as standard, good shock absorption effect, and reduced driver fatigue.
The operation interface is simple, equipped with a multi-function instrument panel and LCD display, which displays the equipment status (such as fuel consumption, engine speed, fault code, etc.) in real time for easy monitoring and maintenance.
Convenient maintenance design
The engine door has a large opening design, and maintenance points such as filter elements and oil inspection ports are within easy reach, which is convenient for maintenance and reduces downtime.
The centralized lubrication system is adopted, and key hinge points can be quickly lubricated through grease nipples to reduce maintenance intensity.
4. Multi-function and adaptability
Rich accessories compatibility
Supports a variety of working tools (such as standard buckets, rock buckets, breaker hammers, hydraulic shears, etc.), and can quickly replace accessories through quick connectors to adapt to diverse working needs (such as excavation, crushing, loading, demolition, etc.).
Optional booms and dipper rods of different lengths can be used to flexibly adjust the operating radius and excavation depth to meet special working conditions (such as deep trench excavation and high-rise building demolition).
Strong terrain adaptability
Adopting a short tail design, the turning radius is small (about 2.7m), which is suitable for narrow space operations (such as urban pipe network construction and indoor demolition).
The track tension is adjustable, the ground contact length is long, the climbing ability is strong (the maximum climbing angle is about 35°), and the stability is excellent when working on rugged terrain or slopes.
5. Intelligence and Economy
Advanced Electronic Control System
Equipped with Carter Electronic Management System (EMS), it can automatically optimize the matching between the engine and the hydraulic system, reduce energy loss, and improve fuel economy (fuel consumption is reduced by about 5-8% compared with the previous generation models).
Supports fault self-diagnosis function, quickly locates the fault point through the display screen, and reduces the difficulty and cost of maintenance.
High residual value and service network
Carter brand recognition is high, 320D second-hand equipment has a high value retention rate, and the resale cost is low after long-term use.
The global after-sales service network is complete, the spare parts supply is sufficient, and the technical support is timely to ensure the continuous operation of the equipment.
Summary
The CAT 320D excavator has “powerful power, reliable and durable, comfortable operation, and convenient maintenance” as its core advantages, and is suitable for users who have high requirements for operating efficiency and equipment stability. Although its purchase cost is relatively high, its low failure rate, low fuel consumption and high residual value in long-term use make its comprehensive cost-effectiveness outstanding in the medium-sized excavator market.
