How to choose a mini excavator based on its tonnage? What are the suitable scenarios for different tonnages?
The core considerations are work space and load requirements: ① 1-ton class (such as Komatsu PC01, Bobcat E10z): with a body width of ≤90cm, it can pass through indoor doors and stairs, making it suitable for indoor demolition, villa yard tidying, and orchard trenching and fertilization; ② 1.5-2-ton class (such as Sany SY18U, Caterpillar 301.7 CR): featuring a tailless turning design, it balances flexibility and power, making it suitable for renovation of old residential areas, pipeline laying, and landscape modeling; ③ 3-ton and above class: with stronger power and deeper excavation depth, it is suitable for excavation of rural housing foundations and construction of small municipal roads. According to data from the China Construction Industry Association, improper selection can increase the overall cost by more than 20%, so it is essential to accurately match the working conditions.
