紧凑型或被称为“迷你型”的挖掘机在美国得到越来越普遍的应用,成为工程机械发展趋势中最为引人注目的设备之一。在日本,0.7～7.5 t 大小的迷你型挖掘机被大量应用于空间狭窄的地方作业,现在在北美的很多工地上也同样看到了它们在大显身手。事实上,在许多实际应用中,这些小型液压挖掘机已经替代了挖掘装载机的工作。设备的使用者们对于它们所具有的稳定性、低接地比压、易操作性以 Compact or so-called “mini” excavators have become increasingly popular in the United States and have become one of the most compelling devices in the development of construction machinery. In Japan, mini-excavators of 0.7 to 7.5 t are used in a large number of places where space is limited, and they are now seen in many sites in North America. In fact, in many practical applications, these small hydraulic excavators have replaced the work of backhoe loaders. The users of the equipment have the stability, low ground pressure, and easy operation for them.
