3.5-t backhoe loader

    This 3.5-ton backhoe loader, with its balanced performance design and versatile functions, has become a powerful tool for small and medium-sized engineering projects, agricultural transformation, and municipal maintenance. Its overall dimensions are 5500mm × 1750mm × 2650mm, paired with a 2070mm wheelbase and 1475mm track width. While ensuring operational stability, it demonstrates excellent flexibility - the minimum turning radius is only 3500mm, and the 250mm minimum ground clearance ensures passability on bumpy roads. Whether it is a rural path or a narrow corner of a construction site, it can easily pass through.

    As an all-rounder integrating loading and excavating functions, its operational capability is particularly prominent. In terms of loading, the 1800mm wide loading bucket has a capacity of 0.5m³, and with a maximum breakout force of 36KN, it can efficiently complete the transfer of materials such as sand and soil. The maximum unloading height is 2800mm and the unloading distance is 800mm, which can be adapted to various transport vehicles. The total operation time of the front shovel is 12 seconds, further shortening the operation cycle. The excavating function is also strong: the 400mm wide excavating bucket has a capacity of 0.1m³, with a maximum digging depth of 2000mm and a radius of 2700mm. The 180° swing angle makes tasks such as ditch trimming and foundation pit excavation easy to handle. The maximum digging force of 25KN and the maximum digging height of 3300mm expand the operation range to meet the needs of diverse scenarios.

    The power system is equipped with a Yunnei YN25GB engine, adopting a direct injection four-stroke design and a 4-cylinder 90mm bore layout. It has a rated power of 37KW and a rated speed of 2400r/min, with stable power output and excellent fuel economy. The transmission system is equipped with a fixed-shaft power shift gearbox, with 2 forward and 2 reverse gears paired with a ZL28F torque converter. Combined with the four-wheel drive design, it ensures efficient power transmission, can easily climb 25° slopes, and has a maximum driving speed of 25Km/h, meeting the needs of cross-regional operations.

    The hydraulic system is centered on a system pressure of 16MPa, driving the full-hydraulic articulated steering (with a steering angle of 33°) and precise operational actions. The operation response is sensitive, and even novice operators can quickly get started. The braking system adopts an oil-brake drum-type service brake, combined with a manual parking brake, and the 330mm braking distance ensures operational safety. The tires are of 20.5-16 specification (both front and rear tire pressures are 250KPa), with strong grip, suitable for complex terrains such as mud and gravel. The 30L fuel tank and 30L hydraulic oil tank capacity design can support long-term continuous operation.

    The 3500Kg weight of the whole machine not only ensures stability during operation but also facilitates transportation and transfer. Reinforced structural components and wear-resistant materials improve the durability of the equipment, and daily maintenance is convenient, effectively reducing the use cost. Whether it is material transfer in small infrastructure, earthwork arrangement in farmland transformation, or ditch excavation in municipal engineering, this backhoe loader can provide users with efficient and reliable operational support with its "multi-functional in one machine" feature.
