    • A conveyor system comprising an overhead rail and a number of self-propelled driving units, movable along the rail for moving associated load carriers such as floor supported carts along the path of the rail by way of a pulling rod connection between the driving units and the load carriers, wherein the pulling rod holding arrangement of each driving unit is operatively connected with an arrangement for urging the driving wheel or wheels of the unit against the rail for increasing the frictional driving engagement therebetween in response to an increased rearward pull in the pulling rod. The vertical component of the pulling force is applied to the driving wheel through a force moment amplifying arrangement, and the horizontal component of the pulling - or pushing - force is applied to the driving wheel through a force direction converter arrangement.
    • 一种输送系统,包括架空导轨和多个自推进驱动单元,可沿着轨道移动,用于通过驱动单元和驱动单元之间的拉杆连接沿着轨道的路径移动相关联的负载托架,例如地板支撑的推车 负载载体,其中每个驱动单元的拉杆保持装置可操作地与用于将该单元的驱动轮或轮抵靠在轨道上的装置连接,以增加其间的摩擦驱动接合,以响应于拉杆中的增大的向后拉 。 牵引力的垂直分量通过力矩放大装置施加到驱动轮,并且拉力或推力的水平分量通过力方向转换器装置施加到驱动轮。
