Share
In the 6-ton mini excavator market, the Shantui SE60 has become the core equipment for municipal engineering, garden construction, farmland water conservancy, housing renovation, and small-scale mining operations, with its solid mechanical quality, efficient operation performance, and comprehensive adaptability. As a benchmark model in Shantui's mini excavator series, it has been fully optimized in core mechanical modules such as power, hydraulics, chassis, and working device, balancing operation efficiency and durability. Every mechanical design is tailored to practical operation needs, which not only inherits the reliable gene of Shantui's construction machinery, but also unlocks diverse construction scenarios through refined upgrades, highlighting the hardcore mechanical strength of 6-ton mini excavators.
The power system is the core strength of the Shantui SE60. The machine is equipped with a Weichai customized WP3.2 electronic injection engine, complying with National IV emission standards, with strong power output and excellent fuel economy. The basic engine components enjoy an ultra-long warranty of 5 years or 10,000 hours, greatly reducing later maintenance costs and risks. The engine is optimized with a turbocharger design, combined with efficient combustion technology, which improves power while reducing fuel consumption; the engine compartment is widened and enlarged, and the air duct is specially optimized, with heat dissipation performance increased by 20% compared with the previous generation, which can effectively avoid high-temperature overload and adapt to the needs of long-term continuous operation. The fuel tank capacity of the machine is 125L, 20% larger than that of traditional models, with significantly improved endurance. At the same time, it is standard equipped with an air pre-filter, which can effectively protect the engine intake system and extend the service life of the engine; the engine oil change capacity is 9.5L, and the coolant is 8L, with a reasonable maintenance cycle, further reducing operating costs.
The upgraded and optimized hydraulic system has achieved dual improvements in the operation fluency and efficiency of the Shantui SE60. The machine is equipped with a new load-sensitive hydraulic system, adopting an axial variable displacement piston pump with a maximum main pump flow of 152L/min, matched with a new generation of low-pressure loss main valve. It can accurately distribute hydraulic flow according to the operation load, with small energy loss, and the single action speed is 5% higher than that of competitors. The coordination of compound actions is excellent, and the operation is smooth without jamming. The main valve adds an arm holding function, which can effectively reduce arm drop, improving operation safety and accuracy; it is equipped with a new large-torque swing motor, with torque increased by 20%, stronger slope operation capacity, swing speed up to 11r/min, stable and sufficient swing power, adapting to operation in complex terrain. The travel motor adopts a large-torque design, with torque increased by 8%, and adds an automatic high-low speed switching function, making travel more powerful and adapting to the movement needs of different operation scenarios.
The mechanical design of the chassis and travel device fully takes into account the stability and durability of the SE60. The machine adopts a new X-shaped crawler frame independently developed by Shantui, with increased wheelbase and track gauge, and the overall stability is 8% higher than that of the previous generation. At the same time, the gap between the upper and lower workshops is increased to avoid soil blockage during operation and improve operation efficiency. It is equipped with a new type of four-wheel drive developed and manufactured by Shantui with 40 years of experience, adopting mature and high-quality forging and heat treatment technology, with good load-bearing capacity and stable and reliable quality. Among them, the supporting wheel is configured with the same specification as the 7T level, which is strong and durable, and the service life is greatly extended. The crawler adopts a full protection design, matched with a double-tooth crawler, which has a stronger grip capacity and effectively reduces wear; the minimum swing radius of the front working device of the whole machine is 2395mm, and the rear swing radius is 1655mm, with flexible swing, enabling dead-angle-free operation in narrow spaces.
The working device adopts a reinforced structure design, with prominent hardcore strength. The upper frame adopts modal analysis technology, which effectively reduces machine vibration and noise while ensuring sturdiness and durability; key stress positions are strengthened to cope with the impact load of harsh working conditions. The bottom plate, side plates, and reinforcing plates of the bucket are all made of high-strength wear-resistant materials, with an optimized bucket shape design, the bucket cutting force is increased by 10%, and the bucket tooth wear resistance is increased by 15%. The standard bucket capacity is 0.22m³, the maximum bucket digging force is 45KN, and the maximum arm digging force is 32KN. The digging performance is strong, which can easily cope with the needs of earthwork excavation, gravel cleaning, crushing, and other operations. It is equipped with an enlarged bulldozer blade, which is raised and widened, making auxiliary construction easier; at the same time, it supports flexible assembly of various accessories such as hydraulic breakers, rippers, wood grabs, and quick-change devices, realizing multi-functional operation and covering diverse construction scenarios.
The mechanical optimization of control and maintenance further improves the operation experience and practicality of the SE60. The machine is equipped with a high-strength special-shaped tube frame cab, configured with fire extinguishers, escape hammers, safety belts and other safety equipment, with a wide front and rear field of vision and high work safety; the all-injection interior is ergonomically designed, matched with a suspended seat and a high-power air conditioner, with excellent shock absorption and noise reduction performance, which can greatly reduce fatigue during long-term operation. It is equipped with a new generation of human-friendly intelligent electronic control system, preset with four working modes: P (heavy load mode), E (economic mode), A (automatic mode), and B (breaker mode), which is easy to switch. At the same time, the vehicle position, operation track, and working status can be viewed in real time through the cloud platform. The whole machine adopts a three-section rear hood design with a large opening range and sufficient maintenance space. The compressor is moved outward, and the tension pulley is canceled. The belt can be adjusted by opening the hood without removing the bottom plate, saving time and effort.
With comprehensive mechanical upgrades, the Shantui SE60 has redefined the performance standard of 6-ton mini excavators. From the stable power of the Weichai customized engine, to the precise control of the load-sensitive hydraulic system, and then to the durable adaptation of the reinforced chassis and working device, every mechanical detail reflects Shantui's R&D strength. It not only has the flexibility and convenience of small equipment, but also has the operational strength comparable to medium and large excavators. It can not only adapt to fine operations such as municipal administration and gardens, but also cope with heavy-duty working conditions such as small mines. It has become the preferred equipment in the 6-ton mini excavator market, providing an efficient and reliable mechanical solution for various small-scale engineering constructions.
