摘要： The canal paving machine has an elongated main frame supported in an elevated position on a pair of end frame structures each of which includes an upper mounting section, a lower traction section and an intermediate connecting section. One mounting section is movably supported on the main frame for movement longitudinally thereof to vary the longitudinal spacing between the end frame structures. Each traction section has front and rear traction units movably connected together to vary the spacing therebetween transversely of the main frame. The connecting section is vertically adjustable relative to the traction section and the upper mounting section is vertically adjustable relative to the connecting section. During a paving operation the upper sections are retracted relative to the connecting sections and the main frame adjusted relative to the ground surface by vertical adjustment only of the connecting sections. For attaching or removing a slip form from the underside of the main frame, the upper sections and connecting sections of the end frame structures are vertically moved to their maximum elevations to provide adequate working space below the main frame.

摘要： The method and power transmission system of this invention for driving a road planar machine has the cutter unit in a positive mechanical drive with the drive shaft of a machine power unit through a hydraulically actuated clutch mechanism. The wheel traction units for the machine are continuously driven from the power unit by hydraulic motors operated by variable volume displacement pumps. A control system for retaining the power unit at a set rotational speed required for a predetermined cutting or planing load is responsive to a drop in the set rotational speed, resulting from the cutting unit encountering an overload, to actuate the variable displacement pumps to decrease the forward speed of the machine without appreciably reducing the rotational inertia force of the cutting unit. If the cutting unit overload is of a short duration or momentary the set rotational speed of the power unit is resumed. If the overload, as observed by the machine operator after the occurrence of the drop in the set rotational speed of the power unit, appears to be severe or prolonged, the control system may be manually discontinued and the machine manually controlled until the cutting unit overload has been removed at which time the control system may again be placed into operation.
摘要翻译：用于驱动道路平面机的本发明的方法和动力传动系统具有通过液力驱动的离合器机构的机械动力单元的驱动轴的正机械驱动的切割单元。机器的车轮牵引单元由动力单元通过由可变容积排量泵操作的液压马达连续驱动。用于将功率单元保持在预定切割或刨削负载所需的设定旋转速度的控制系统响应于由于切割单元遇到过载而导致的设定旋转速度的下降，致动可变排量泵以减小机器的前进速度，而不明显地降低切割单元的旋转惯性力。如果切割单元过载时间短或瞬时，则恢复设置的动力单元的转速。如果机器操作员观察到的过载发生在动力单元的设定转速下降之后，看来是严重的或长时间的，则控制系统可以手动停止，机器手动控制，直到切割单元过载已经被移除，此时控制系统可以再次被投入运行。

摘要： This invention pertains to a method and machine for slip forming concrete wall structures such as median barrier walls for highways. The slip form comprises a pair of opposite side walls each of which has a skirt member retractable and extensible relative to the lower portion thereof. A top wall separate from the side walls is mounted on the machine frame between the upper portions of the side walls, and each side wall and associated skirt member is movable as a unit relative to the top wall and each skirt member is independently movable relative to an associated side wall. The side walls are adjustably supported on the machine frame for adjustment laterally of the machine frame to accommodate top walls of varying widths and the top wall is verticaly adjustable relative to the machine frame independently of the side walls. Power means provide for a controlled relative movement of the side walls, skirt members and top wall and the relative arrangement of the side walls and top wall is such that a glare shield can be formed over any selected section of the barrier wall without interrupting the continuous advance of the machine in the forming of the barrier wall with linear and reversely curved sections.
