    • A tow truck includes a pair of booms comprised of two identical channel-shaped members being secured together in face-to-face relationship to form a space therebetween. Each of the members includes serrations in the side walls in a common transverse plane at the center of the boom and the serrations are closed by weldments. The boom is constructed by taking a blank sheet of rectangular material and shaping it to taper it from the transverse center to the outer ends along all of its edges and providing inwardly shaping V-shaped notches along the transverse centerline. Side walls are then formed by bending and then the resulting two channel-shaped members are placed in edge-to-edge engagement along one end and held in this position by welding while the opposite ends are drawn together such that bending occurs in a plane through the vertexes of the V-shaped notches and the notches are closed. All abutting edges are then welded together to complete the boom.
    • 牵引车包括一对起重臂,其由两个相同的通道状构件组成,其以面对面的关系固定在一起,以在它们之间形成空间。 每个构件在悬臂的中心处的共同横向平面中的侧壁中包括锯齿,并且锯齿由焊件封闭。 起重臂是通过取一块矩形材料制成的,并将其成形为使其沿着其所有边缘从横向中心到外端逐渐变细,并沿横向中心线向内成形V形凹口。 然后通过弯曲形成侧壁,然后将所得到的两个通道状构件沿着一端沿边缘到边缘接合放置并且通过焊接保持在该位置,同时将相对端拉在一起,使得弯曲发生在平面通过 V形凹口和凹口的顶点是封闭的。 然后将所有的邻接边缘焊接在一起以完成起重臂。

    • A mobile load handling machine primarily in the form of a crane is provided in which a jib is pivotally mounted from the machine chassis on upstanding mutually inclined linkage which interconnects front and rear wheeled portions of the machine chassis, which chassis portions are movable relative to one another along the fore and aft axis of the machine while ram means and tie linkage are pivotally connected between a mounting member movable in a fore and aft direction on one of the chassis portions and the jib whereby on extension and retraction of the ram means it operates in conjunction with the tie linkage to effect raising and lowering luffing movement of the jib and also operates in conjunction with the mutually inclined linkage to effect relative retraction of the chassis portions to reduce the wheel base of the machine on raising of the jib and vice versa.
