卡特 CAT420F

The CAT 420F is a multi-functional backhoe loader produced by Caterpillar since 2012. It combines the material handling capabilities of a loader with the digging capabilities of a backhoe, making it suitable for various operations in construction, agriculture, forestry, and municipal industries. It's a highly efficient and versatile workhorse on construction sites. Here is a detailed description: Core Power and Performance: Equipped with a Caterpillar C4.4 ACERT diesel engine, 4.4L displacement, rated power 70kW, net power approximately 69kW, and maximum torque 438N・m, providing stable power output and economical fuel consumption. The loader has a bucket capacity of 0.96m³ and a bucket digging force of 51.1kN; the backhoe has a digging force of 62.66kN, a maximum digging depth of 4.36m, and a maximum horizontal working range of 5.612m. It can efficiently complete tasks such as ditch digging and material loading, with a maximum travel speed of 40km/h, allowing for flexible and efficient relocation. Practical Configuration and Design: Equipped with a variable flow axial piston hydraulic pump, the hydraulic system achieves a flow rate of 163L/min, ensuring precise and smooth operation. Standard factory-installed outrigger stabilizers enhance machine stability during operation. The ergonomically designed cab features joystick controls and ample legroom, reducing operator fatigue during extended work periods; it also includes a diesel particulate filter, meeting US EPA Tier 2 emission standards. Tire specifications are 11L-16 (12-ply) for the front and 19.5L-24 (12-ply) for the rear, adaptable to various road conditions. Suitable Scenarios and Advantages: Widely used in highways, railways, infrastructure, and mining, it can shovel and transport bulk materials such as sand, gravel, and coal, and can also perform light earthmoving, site leveling, and other tasks. With attachment changes, it can also be used for material hoisting and short-distance transport. Leveraging Caterpillar's global service network, spare parts supply and technical maintenance are convenient, ensuring stable performance for both long-term engineering operations and temporary construction in various scenarios, balancing practicality and reliability.
