This equipment is model 320D (also known as Cat320D), a classic medium-sized excavator under Caterpillar. Manufactured within the last 5 years, it is in relatively new condition with low wear on core components, ensuring long-term stable operation. With an operating weight precisely controlled at 20 tons, it is a widely used medium-sized model in construction. It not only has sufficient operating strength but also avoids the high energy consumption and high transfer cost of large equipment, suitable for various scenarios such as mines, infrastructure construction, and municipal engineering.
2. Core Performance Parameters
In terms of digging performance, the equipment is powerful: it has a bucket digging force of 132kN and a stick digging force of 99kN. The strong digging force ensures efficient handling of materials such as soil, sand, and medium-hard rocks. With a maximum digging radius of 9710mm, a maximum digging depth of 6550mm, a maximum digging height of 9440mm, and a maximum dump clearance of 6770mm, its wide operating range can meet diverse operational needs such as deep pit digging and high-altitude unloading.
The power and traveling system have excellent adaptability: equipped with a 6.4L displacement engine, it provides stable power output. Combined with a 320L large-capacity fuel tank, it can reduce refueling frequency and improve continuous operation efficiency. The traveling speed is divided into two gears: low gear at 3.5km/h and high gear at 5.5km/h. The low gear is suitable for precise movement during operation, while the high gear improves transfer efficiency. With a gradeability of 70% (high gear)/35% (low gear), it can drive stably even on complex terrains such as mountains and slopes, breaking through terrain limitations.
3. Structure and Dimension Details
The equipment's structural design balances stability and convenience: the track shoe width is 600mm. The reasonable width design enhances ground adhesion and improves operation stability while reducing rolling damage to the ground, making it suitable for various operation grounds such as lawns and hardened roads. The transportation dimensions are optimized: total transportation length 9390mm, total transportation width 2800mm, total transportation height 3050mm. The cab height is consistent with the total transportation height. The compact dimensions make it easier to pass through transportation facilities such as bridges and tunnels during transfer, reducing transportation costs.
4. Comprehensive Advantage Summary
The Caterpillar 320D excavator stands out with its core advantages of "strong performance + high adaptability + high reliability". The relatively new manufacturing year lays the foundation for low-fault operation of the equipment. The 20-ton weight is suitable for most medium-sized engineering needs. The strong digging force and wide operating range improve construction efficiency. The flexible traveling system and compact transportation dimensions enhance scenario adaptability. The combination of 6.4L displacement and 320L fuel tank ensures operation endurance. It is a medium-sized construction equipment with outstanding comprehensive cost-effectiveness.
