Share
In the 3.8-ton mini excavator segment, the Shantui SE36SR stands out as a leading piece of equipment for municipal engineering, garden construction, housing renovation, farmland water conservancy, and other scenarios, thanks to its robust mechanical configuration, precise control, and efficient operation. As a flagship model in Shantui's mini excavator series, it features comprehensive upgrades to core mechanical modules, including power, hydraulics, chassis, and working device, while balancing compactness and strength. Every mechanical design is tailored to practical needs, redefining the performance benchmark for 3.8-ton mini excavators.
1. Power System: Efficient, Eco-Friendly, and Stable Output
The SE36SR is powered by a Japanese Yanmar 3TNV88F three-cylinder direct-injection engine with a displacement of 1.642 L and a rated power of 18.2kW at 2200rpm, meeting China IV, EU Stage V, and North American EPA Tier 4 Final emission standards, balancing power and environmental protection. The engine uses advanced combustion technology to deliver excellent fuel economy. Paired with a large-capacity cooling system, it ensures continuous operation without overheating. With an engine oil capacity of 6.7L, a hydraulic oil tank of 40L, and a fuel tank of 50L, it greatly extends maintenance intervals and reduces operating costs. Its compact layout saves internal space while reasonably controlling the operating weight at 3,880kg, laying a solid foundation for flexible movement and stable operation.
2. Hydraulic System: Precise, Efficient, and Smooth Control
The hydraulic system is the SE36SR's core advantage. It features a load-sensitive control system with a variable-displacement piston pump, delivering a rated working flow of 96.8 L/min and a system pressure of 24.5 MPa. It accurately distributes hydraulic flow based on load, minimizing energy loss and ensuring excellent synchronization of compound movements with smooth, jitter-free operation. The travel motor has an automatic speed-regulation function, with two travel speeds (2.4/4.4km/h), that adapt to different working conditions. It boasts strong traction and a climbing capacity of 30° (58%). Standard dual-circuit high-pressure lines support various attachments such as hydraulic breakers, shears, augers, and quick couplers, enabling multi-functional operation. The optimized hidden pipeline layout reduces collision and leakage risks, and dedicated filters keep the hydraulic system clean, extending component life.
3. Chassis and Travel: Stable, Reliable, and Flexible Adaptation
The machine has a compact overall dimension (total length 4,880mm, total width 1,740mm, total height 2,550mm) with a minimum ground clearance of 295mm, allowing easy access to narrow spaces. The chassis adopts a reinforced crawler design with a shoe width of 300mm and a track gauge of 1,440mm. The ground pressure is only 32kPa, making it suitable for soft ground and preventing sinking. The travel mechanism is fully hydraulically driven with an integrated travel motor and reducer, featuring high transmission efficiency and reliability. The swing frame is made of high-strength cast steel with an optimized structure, providing excellent impact resistance for harsh working conditions.
4. Working Device: Powerful Digging and Dead-Angle-Free Operation
The working device features a zero-tail-swing and boom-swing design, with a rear tail-swing radius of only 860mm. The boom can swing left and right, and combined with a swing speed of 0-9r/min, it enables dead-angle-free operation in confined spaces. Key structural parts are made of high-strength wear-resistant steel with reinforced stress points, greatly enhancing durability. The standard bucket has a capacity of 0.12 m³ and a width of 650mm, with a bucket digging force of 30.4 kN and an arm digging force of 18.2 kN, delivering strong digging performance. It offers a maximum digging depth of 3,075mm, a maximum digging radius of 5,500mm, and a maximum dumping height of 3,545mm, covering a wide operating range and easily handling earth excavation, dredging, crushing, and other tasks.
5. Control and Maintenance: Ergonomic Design and Convenient Efficiency
The cab follows ergonomic principles, equipped with a mechanical-suspension seat, heating and cooling air conditioning, and a 7-inch intelligent touchscreen integrating Bluetooth, USB, and radio functions, providing a wide field of vision and comfortable operation. Shantui. Full hydraulic pilot control ensures precise and effortless operation. The machine features large-area, openable covers that allow maintenance from the ground. Filters and lubrication points are centrally arranged for easy servicing. Shantui. It is equipped with pressure-release mechanical braking and multiple safety protection devices, ensuring comprehensive operational safety.
With its robust mechanical configuration, the Shantui SE36SR delivers a balanced mix of power, hydraulics, stability, and versatility in the 3.8-ton mini excavator class. It meets the needs of narrow-space operations while delivering efficiency comparable to larger equipment, making it an ideal choice for small-scale construction projects.
