Equipped with the reliable YUCHAI YC4A105Z-T20 turbocharged diesel engine, the 388 backhoe loader delivers strong and stable power output for demanding working environments. The engine adopts a four-stroke turbocharging system with a rated power of 75KW at 2200r/min, providing continuous power support for loading, digging, lifting, and transportation operations. With a maximum torque of 400N.m and a displacement of 4.837L, the machine maintains excellent performance even during heavy-duty applications. The engine also features low fuel consumption of only 230g/km.h, helping users effectively reduce operating costs while improving overall productivity.

The overall operating weight of the machine reaches 8200KG, which greatly enhances operational stability during excavation and loading work. The transport dimensions of 6050×2465×3100mm ensure convenient transportation between project sites while maintaining excellent maneuverability in confined working areas. The wheelbase of 2280mm and minimum ground clearance of 300mm provide strong terrain adaptability, allowing the machine to operate efficiently on rough construction roads, muddy farmland, gravel surfaces, and uneven ground conditions.

The front loader system is designed for high-efficiency material handling operations. The large 1.0m³ bucket capacity allows operators to quickly load sand, gravel, soil, coal, crushed stone, and construction materials. The loader lifting capacity reaches 2500KG, enabling efficient transportation and loading tasks in construction projects and industrial applications. With a powerful breakout force of 47KN, the bucket can easily penetrate hard soil and compacted materials, significantly improving working efficiency. The bucket dumping height of 2650mm and dumping distance of 1025mm ensure smooth unloading into trucks and material containers, reducing loading cycle times and increasing productivity on job sites.

The rear excavator system provides outstanding digging capability for trenching, foundation excavation, and pipeline installation projects. The backhoe bucket capacity is 0.3m³, making it suitable for precise excavation work in urban construction, agricultural engineering, and utility maintenance. The maximum digging depth reaches 4085mm, allowing the machine to handle deep excavation operations efficiently. The excavator grab supports a 180° swing angle, greatly expanding the operating range and improving flexibility in narrow working environments. The excavator digging force reaches 50KN, while the dipper digging force is 31KN, providing strong excavation power even when working with hard clay, compacted soil, or rocky ground conditions.

The advanced hydraulic system ensures smooth, responsive, and efficient machine operation. The optimized hydraulic design improves working accuracy and reduces operator fatigue during long-term operation. The bucket lifting time is only 6.8 seconds, lowering time is 3.1 seconds, and bucket discharge time is 2.0 seconds, allowing the machine to complete loading cycles quickly and efficiently. The hydraulic system delivers stable pressure and reliable performance under continuous heavy-duty working conditions, ensuring long service life and reduced maintenance requirements.

The transmission system adopts a durable fixed shaft power transmission gearbox designed for stable performance and long-term reliability. The gearbox features 2 forward gears and 2 reverse gears, allowing operators to easily adapt to different working conditions and travel requirements. The machine is equipped with the YJ290 single-stage three-element torque converter with a maximum efficiency of 84.4%, ensuring smooth power transmission and excellent fuel efficiency. The oil-cooling pressure circulation cooling method effectively reduces transmission temperature during continuous operation, improving durability and operational stability. The maximum travel speed of 24Km/h enhances machine mobility and improves transportation efficiency between different work areas.

The steering system adopts the BZZ5-250 steering device with a steering angle of 36°, providing precise steering control and excellent maneuverability. The minimum turning radius is only 6581mm, enabling flexible operation in narrow construction zones and crowded urban projects. The steering hydraulic system pressure reaches 12Mpa, ensuring smooth and stable steering performance under heavy load conditions.

The heavy-duty axle system adopts a double reduction main transmission structure combined with a single-stage final reducer, providing strong load-bearing capacity and excellent durability. The axle rated load reaches F22.5t/R18.5t, ensuring reliable performance during high-intensity loading and excavation operations. The reinforced axle design effectively improves traction performance and operational stability on uneven terrain and difficult working environments.

The 388 backhoe loader uses high-quality tires sized 14-17.5/19.5L-24, providing excellent wear resistance, anti-slip capability, and strong ground grip. The optimized tire pressure configuration improves machine balance and enhances driving comfort during transportation and operation on various road conditions.

Safety and reliability are important advantages of the 388 backhoe loader. The machine adopts an advanced air-over-oil caliper brake system with self-regulation and self-balance functions, ensuring stable and efficient braking performance during operation and transportation. The emergency brake system combines operation power implementing brake and manual operation power terminating brake, significantly improving driving safety in emergency situations and on sloped working surfaces.

The operator cabin is designed with consideration for comfort, visibility, and operational convenience. The ergonomic control layout helps reduce operator fatigue during long working hours. Wide viewing angles improve working visibility and operational accuracy, while the comfortable seat and user-friendly instrument panel enhance the overall driving experience.

The 388 backhoe loader is widely suitable for various industries and applications, including:

• Road construction and maintenance

• Municipal engineering projects

• Building foundation excavation

• Pipeline and cable installation

• Farmland and agricultural operations

• Landscaping and gardening projects

• Mining and quarry material handling
