The amusement excavator excavator according to engineering works, the use of electro-hydraulic components and design of a suitable excavator adults and children's entertainment, sports use. 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 the use of safety, entertainment 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. Children's play is based on the engineering excavator excavator works with the design and development of an educational play equipment, all the parts for export standard engineering durable parts, using international advanced technology, has been successfully applied for national patents, elegant simplicity, workmanship, electric hydraulic excavators for the whole simulation. Operation, function and engineering excavator same can be rotated. Suitable for indoor and outdoor playgrounds in parks, squares, scenic areas and other places. Child psychology experts confirmed that growth and development of children should have more contact with hands-class recreational facilities, intellectual development of children up to exercise children hands-on brain coordination. Can be 60 degrees, 90 degrees rotation free exchange, and to be based on the size of your site to adjust the rotation angle. Business diversification, operating experience, contests, also according to the digging of the award, participate in interactive games, appearance, entertaining, attendance advantages, since the market by the majority of users of all ages and praise.
