发明名称 Truck mounted backhoe
摘要 The present invention relates to a truck mounted backhoe supported by a frame that pivots between a use position and a transport position in an uninterrupted movement. The support frame is interconnected to the truck by a linkage assembly having two links pivotally connected at adjacent ends with the opposite ends connected to the frame and the truck respectively. A hydraulic cylinder is connected at the adjacent connecting point to push and pull the frame between the use and transport positions. Further, a control station is provided which is pivotally interconnected with the support frame and is moved with respect to the frame as the frame moves between the use and transport position to prevent interference with the backhoe. A bracing frame is provided to retain the frame in a substantially vertical position when in use.
