The amusement excavator excavator according to engineering works, the use of electro-hydraulic components and design of a suitable adult and children *, sports simulation using excavators. Its actions and methods of operation and engineering excavator same realization unlimited 360 ° rotation and the bucket, arm, alone or co-operation of the boom. With high simulation, safety, * and other characteristics, can bring a strong sense of real-life experience for the driver. Introduction to the principles and operation of the device is an electro-hydraulic products play equipment, the most up to the chassis, rotary components, boom, arm, bucket, power unit, a control unit, a hydraulic unit, an electronic control system. Individual municipal electric motor driven hydraulic unit access, multi-valve controlled by a hydraulic circuit to achieve rotation direction, bucket, arm, alone or co-operation of the boom.
