Recommended Compact Short-tail Excavators: 7-8 Ton Models Leading Urban Construction and Personal Purchase

Compact excavators are increasingly popular, especially among individual buyers who form the largest user group for these machines. Initially designed for urban construction, compact excavators are favored for their low noise, small working radius, and excellent mechanical performance, significantly reducing the need for manual labor and improving work efficiency. This makes them crucial in urban construction.

Nowadays, individual users are the largest consumer group for compact excavators, particularly for large farms, orchards, warehouses, and urban landscaping. Although the 7-8 ton compact excavators may have slightly less performance than conventional hydraulic excavators, they are designed to minimize usage restrictions and maximize work efficiency. Currently, most of the compact short-tail excavators sold by TD are used by individual users. The demand for compact excavators in Europe, Africa, the Middle East, and Asia has been rising annually. Today, we introduce four compact excavators. For budget-conscious users, Tiedou's used compact excavators, costing only one-third of the new models, are a suitable and cost-effective option.
