    CPC classification number: B60P1/56

    Abstract: A LARGE CAPACITY, TRANSPORT VEHICLE HAVING REDUCED OVERALL HEIGHT AND CENTER OF GRAVITY WITH IMPROVED UNLOADING CHARACTERISTICS INCLUDES AS BODY HAVING THREE REINFORCING BEAMS ARRANGED LONGITUDINALLY ALONG ITS CENTER AND TWO SIDES. TWO SIDE-BY-SIDE PAIR AS OPPOSITELY HINGED DOORS EXTEND LONGITUDINALLY THROUGH THE BODY AND ARE PIVOTED RESPECTIVELY TO THE CENTER BEAM AND ONE OF THE SIDE BEAMS. MEANS ARE INCLUDED FOR OPENING AND CLOSING THE TWO PAIRS OF DOORS. THE DOOR ARRANGEMENT EFFECTIVELY PERMITS SUBSTANTIAL REDUCTION IN THE VEHICLE DRAFT. THE ARRANGEMENT OF THE THREE BEAMS PROVIDES STRENGTH IN THE BODY FOR SUPPORTING LOADS AS GREAT AS 100 TONS OR MORE. THIS FEATURE IS EXEMPLIFIED IN A PREFERRED EMBODIMENT WHERE THE BEAMS EXTEND REARWARDLY OF THE BODY AND ARE SECURED TO AN AXLE SUPPORTING THE REAR OF THE VEHICLE. IN THIS PREFERRED EMBODIMENT, THE REAR WHEELS MAY BE ARRANGED GENERALLY WITHIN THE LATERAL DIMENSION OF THE BODY.

    Abstract: A modular bottom dump trailer structure includes a pair of laterally spaced, substantially upstanding side wall modules, a rear end wall module laterally pilotable abuttingly secured to the side wall modules, a front end wall module laterally pilotably abuttingly secured to the side wall modules, and a pair of hopper floors oppositely outwardly, upwardly inclinably secured to the side wall modules and endwardly secured to the end wall modules to define a central elongated opening therebetween for egress of material carried in the trailer structure. Each wall module includes only a single thin plate member adapted to be loaded in tension with bracing members secured internally thereof. A V-shaped draft beam is pilotably secured to the side wall modules rearwardly of the front end wall module to provide strength and stability for the trailer structure.

    CPC classification number: E02F3/80

    Abstract: Two or more tractor vehicles are disposed in a highly stable unitized side-by-side relationship to apply increased tractive effort to a single working implement such as a bulldozer blade. Disengageable bracing structure couples the adjacent tractors to maintain parallelism and a pre-determined longitudinal relationship without subjecting localized regions of the assembly to excessive stress. In a preferred form, the bracing maintains these relationships while providing for independent oscillations of the tractors in response to terrain irregularities.

    Abstract translation: 两台或多台拖拉机车辆以高度稳定的并排关系布置，以将增加的牵引力应用于诸如推土机叶片的单个作业工具。 可拆卸的支撑结构将相邻的拖拉机联接以保持平行度和预定的纵向关系，而不会使组件的局部区域过度受力。 在优选形式中，支撑件维持这些关系，同时响应于地形不规则性而提供拖拉机的独立振荡。

    Abstract: An articulated vehicle is provided with a bifurcated front frame having forwardly extending side members supported by wheels at the outer ends thereof. An elongated tine, located between the side members, is attached on the front frame by a parallelogramtype linkage means for lifting and carrying a load thereon. One pair of links forming the linkage means comprise hydraulic cylinders adapted to selectively tilt the tine to enable the load to be more easily picked up and retained while being carried.

    Abstract translation: 铰接式车辆具有分叉前框架，其前端部具有由车轮支撑的向前延伸的侧构件。 位于侧构件之间的细长齿通过平行四边形连接装置安装在前框架上，用于提升和承载载荷。 形成连接装置的一对连杆包括适于选择性地倾斜齿的液压缸，以使得能够在承载时更容易地拾取和保持负载。
