8-Tonne Backhoe Loader

This 8-ton backhoe loader, with its all-round performance that balances power and flexibility, has become a core equipment in medium and large-scale engineering construction. Whether it is for municipal infrastructure, auxiliary mining operations, or large-scale agricultural development, it can meet diverse needs with its efficient and integrated operational capabilities.

In terms of core power and transmission system, it is equipped with a Yuchai 75W engine (other models can be selected as needed), featuring an in-line, direct injection four-stroke design combined with an injection combustion chamber technology. This ensures full fuel combustion and stable, powerful power output. The transmission system is equipped with a YJ280 torque converter; its single-stage, three-element structure achieves a maximum efficiency of 84.4%. Paired with a fixed-shaft power shift gearbox that offers two forward gears and two reverse gears, the maximum speed can reach 28Km/h. This not only meets the requirements of low-speed precision operations on-site but also enables quick site transfers, significantly reducing non-operational time losses. The final drive adopts a single-stage reducer, with the front axle having a rated load of 8t and the rear axle 18.5t, which is sufficient to withstand the strong pressure during heavy-load operations and ensure efficient power transmission to the drive wheels.

In terms of operational performance, the synergistic advantages of the dual functions of loading and excavation are particularly prominent. The loading end is equipped with a 1.0m³ capacity bucket, and its breakout force of 38KN can easily handle the loading of materials such as sand, gravel, and soil. Combined with a loading lifting capacity of 2500kg, it can efficiently complete material transfer. The bucket dumping height reaches 2700mm and the dumping distance is 925mm, allowing direct unloading into medium-sized dump trucks and reducing secondary transfer links. The excavation end is equipped with a 0.3m³ backhoe bucket, with a maximum digging depth of up to 3800mm (an optional extended arm can achieve 4500mm). The 190° swing angle of the excavator grab expands the operational range, enabling precise force application in foundation pit excavation, ditch trimming, or hard soil crushing. The combination of a maximum pulling force of 39KN and a breakout force of 38KN ensures a stable operational rhythm even when dealing with hard rock formations or heavy materials.

The passability and stability of the equipment have been carefully designed to provide reliable protection for complex working conditions. The overall operating weight of the machine is 8000kg, with transport dimensions controlled at 6120×2410×3763mm, a wheelbase of 2246mm, and a minimum ground clearance of 300mm, which is sufficient to handle bumpy roads and avoid chassis collisions. It is equipped with 14-17.5/19.5L-24 tires, with the front wheel pressure at 0.55Mpa and the rear wheel pressure at 0.223Mpa. The wide tire surface and reasonable pressure settings not only ensure grip on complex terrains such as muddy ground and mountains but also reduce rolling damage to paved roads. The brake system is equipped with an emergency brake that uses power to implement braking; combined with the precise control of the transmission system, it ensures parking safety during high-speed transfers or heavy-load operations, providing a solid safety backup for operators.

In terms of detailed design, the equipment balances durability and practicality. The clutch oil pressure of the fixed-shaft power transmission gearbox is stable at 1373Kpa-1569Kpa, ensuring smooth gear shifts without impact and reducing mechanical wear. The single-stage final drive has a simple and reliable structure, with low maintenance costs, and can meet the durability requirements of high-frequency operations. The cab is 2900mm above the ground, providing operators with a wide field of vision, facilitating observation of the working surface and the surrounding environment, and improving operational precision. Whether it is efficient material transfer during loading, deep excavation operations, or flexible movement in complex terrains, this 8-ton backhoe loader can provide a one-stop solution for medium and large-scale engineering construction with its powerful power output, stable structural design, and humanized detailed configurations, significantly reducing equipment investment and management costs and helping projects progress efficiently.
