Abstract
A drive roller unit for driving articles such as freight containers on a conveyor track comprises first and second drive rollers which can be driven in rotation. The drive rollers are arranged in juxtaposed relationship in their axial direction and in the drive position thereof are both in engagement with the bottom of the article to be moved. A motor assembly for driving the drive rollers is coupled thereto by way of a differential transmission. One output of the differential transmission drives one drive roller of the pair while the other output of the differential transmission drives the other drive roller. The arrangement of the drive rollers, motor assembly and transmission is mounted rotatably about a vertical axis, and the unit has a mechanism for producing a predetermined braking effect both in respect of the differential pinions of the differential transmission and also in respect of the rotary movement about the above-mentioned vertical axis, thereby to provide that, when movement of the article is impeded during for example the operation of loading same into an aircraft freight compartment, a rotary movement of the arrangement is produced, which causes the article to move angularly stepwise into a desired position. The unit can be used for loading containers into the freight compartment of an aircraft, when the containers must not only be moved into the freight compartment transversely with respect to the longitudinal axis of the aircraft, but at the same time they must also be turned through an angle of up to 90.degree..
