Compact excavator

A compact or mini excavator is a tracked or wheeled vehicle with an approximate operating weight of up to 8.5 tonnes. It generally includes a standard backfill blade and features independent boom swing. At the lightest end, machines with an operating weight below one tonne are commonly called micro excavators.
Hydraulic excavators are somewhat different from other construction equipment in that all movement and functions of the machine are accomplished through the transfer of hydraulic fluid. The compact excavator's work group and blade are activated by hydraulic fluid acting upon hydraulic cylinders. The excavator's slew (rotation) and travel functions are also activated by hydraulic fluid powering hydraulic motors.
