Backhoe with multi-movement capabilities

摘要

A backhoe comprises a support member pivotally mounted thereon for horizontal swinging movements relative thereto by actuating means operatively interconnected between the support member and frame. A boom is pivotally mounted on the support member for horizontal pivotal movements relative thereto by a first hydraulic swing motor and a dipper stick assembly is pivotally mounted on said boom for vertical pivotal movements relative thereto by a hydraulic cylinder pivotally interconnected therebetween. The dipper stick assembly comprises a support bracket having a dipper stick rotatably mounted therein and a dipper bucket mounted on a lower end of the dipper stick. A second hydraulic swing motor is operatively interconnected between the dipper stick and the bracket for selectively rotating the dipper stick thereon.
