Its structural design is closer to that of a traditional excavator, and components such as the chassis and slewing bearing have been proven in the market over a long period of time. The reinforced chassis can adapt to more complex outdoor construction site environments. Moreover, the rear layout provides more space for maintenance of core components such as the engine and hydraulic system. During routine maintenance and troubleshooting, it is not necessary to disassemble too many obstructing parts, reducing maintenance difficulty and downtime.

With the same configuration, models with tailpipes are usually more affordable than those without, making them attractive to individual contractors or small construction teams with limited budgets. In open outdoor construction scenarios, such as field clearing, large courtyard renovations, and rural road repairs, where there are no space constraints, it can complete continuous operations thanks to its stable power output and lower operating costs, and its fuel economy is even more advantageous when working in open areas.
