    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: A mounting arrangement for supporting a bulldozer blade on a vehicle having a C-frame wherein the blade is supported by a centrally located universal ball joint on the C-frame and a pair of longitudinally arranged hydraulic jacks. In addition to providing a simplified three-point mounting for the blade, blade angle and pitch may both be controlled by the single pair of jacks. Preferably, a generally horizontally tilt cylinder is pivotally connected between the back of the blade and a tower structure on the C-frame to stabilize the mounting structure and provide means to tilt the blade.

    Abstract translation: 一种用于在具有C形框架的车辆上支撑推土机叶片的安装装置，其中所述叶片由位于所述C形框架上的居中定位的通用球窝接头和一对纵向布置的液压千斤顶支撑。 除了为刀片提供简化的三点安装之外，刀片角度和俯仰角都可以由单对插孔控制。 优选地，大致水平方向倾斜的气缸枢转地连接在叶片的后部和C形框架上的塔架结构之间，以稳定安装结构并提供使桨叶倾斜的装置。

    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.
