CATERPILLAR FOR SPREADING EARTH MATERIALS

摘要

A caterpillar for spreading earth materials is provided to prevent accidents by rotating the container box freely and releasing earth material at the accurate location. A caterpillar for spreading earth materials comprises a car body(110), a rotary column(120), a container box(130), an engineer's cabin(140), and a swivel bearing(150). The car body travels by driving wheels(111). The rotary column is located on the top of the car body and rotates. The container box is located on the top of the rotary column and regulates the inclination by stroke extension/contraction of a hydraulic system. The engineer's cabin is installed on the rotary column. The swivel bearing is mounted between the car body and the rotary column.
