一种车辆，其构造有推土机铲和一对铰接推臂，该推臂可以通过独立可延伸的液压千斤顶的操作而折叠或展开，以相对于车辆延伸或缩回铲。推臂具有短部件和长部件，短部件和长部件枢转地互连，短部件枢转地连接到车辆，长部件枢转地连接到叶片。机械止动件防止移动超过完全缩回位置。还利用可延伸的千斤顶来控制叶片的高度、倾斜和俯仰，并且提供稳定连杆来抵抗叶片在负载下相对于车辆的横向运动。
A vehicle is constructed with a bulldozer blade and a pair of articulated push arms which may be folded or unfolded by operation of independently extendible hydraulic jacks to extend or retract the blade relative to the vehicle. The push arms have short and a long component which are pivotally interconnected with the short component being pivotally connected to the vehicle and the long component being pivotally connected to the blade. A mechanical stop prevents movement beyond a fully retracted position. Extendible jacks are also utilized to control the elevation, tilt and pitch of the blade and a stabilizing link is provided to resist lateral movement of the blade relative to the vehicle under load.
