How Does an Excavator Without Tracks Work? Shantui SE215EV-X Has the Answer
October 15,2026
Recently, inside an enclosed workshop at a recycling enterprise in Guangdong, Shantui's SE215EV-X cable-supplied electric excavator has run steadily for thousands of hours, meeting round-the-clock operation with excellent power consumption. It is a successful application of a trackless cable-supplied electric digging solution in the recycling sector, offering an efficient, green alternative for heavy-duty work in enclosed spaces through an innovative product form and customized solution.
Innovative Structure: Dropping the Undercarriage Overturns Tradition
Workshops for recycling disposal present special operating conditions, where conventional excavators suffer from travel dust, crawler wear debris, noise and vibration, and floor crushing damage. The Shantui SE215EV-X innovatively adopts a cement-pile fixed solution, completely removing the traditional traveling frame, travel motor, reducer, rotary joint, hydraulic lines and the complete running-gear assembly. Fixed on the cement piles, the digging impact load is transferred directly to the foundation, giving the machine less vibration and better boom-combination stability, especially suited to fixed-point breaking, material raking and feeding. A maintenance channel under the cement piles simplifies upkeep and lowers the overall machine cost.
Electric Power: Green Efficiency with Double Benefits
As a purely electric machine, the SE215EV-X shows unmatched environmental advantages inside an enclosed workshop. The supply cable no longer drags with the machine, simplifying cable layout and eliminating the risk of crushing, pulling and bending fatigue, meeting enclosed-space fire-safety requirements. The machine runs with no travel noise, no crawler dust or rubber debris, and no floor crushing, making cleaning and maintenance easier. At the same time, it occupies less space and needs no travel aisle, freeing more floor area for material storage and discharge. The economic benefit is equally clear: compared with a same-class fuel excavator, a single unit can save considerable energy cost each year, with sharply lower maintenance expenses.
Meeting Challenges Head-On: Custom Solutions Tackle the Hard Problems
In the early stage, the trackless solution faced many technical challenges. The cement piles and embedded parts were difficult to build, requiring precise calculation of digging impact load and overturning moment, plus pull-out and slip-resistance checks. Some civil contractors lacked such calculation experience, and pile design and anchor-bolt layout precision were hard to meet. Shantui's project team went deep on site, provided technical guidance and assisted with the calculations for the specific workshop, communicating process requirements and precautions in time, and finally completed pile construction and equipment installation and commissioning. The team also enriched its technical reserve and project experience for the trackless solution, laying a solid foundation for faster customer response and shorter project cycles ahead.
Winning Trust: Setting an Industry Application Benchmark
After more than 2,300 hours of continuous operation, the customer gave the SE215EV-X high praise: 'Great value for money, very low power consumption, big savings on operating cost, stable and reliable quality, meeting continuous-operation needs.' The operator reported: 'Strong power, fast action, good coordination, flexible material handling; low noise, little vibration, safe and comfortable to drive, easy to maintain.' Based on the good experience, the customer plans to keep purchasing Shantui equipment.
This innovative application of the SE215EV-X in the recycling sector not only fully validates the technical feasibility and economic superiority of the trackless cable-supplied electric excavator in fixed-point, enclosed-workshop operations, but also provides a replicable success model for similar working conditions. From product customization to solution innovation, Shantui, oriented to customer needs, keeps expanding the boundaries of electric-equipment applications, contributing more Chinese wisdom and Chinese solutions to the global green transformation of construction machinery.
