ABSTRACT:
The present invention provides that an overhead suspension system is provided with at least two suspension rails which are parallel, and at least one trolley which runs on the rails, the trolley having respective rollers which respectively engage the rails for the firm mounting of the trolley on the rails.
In a particular example, there is provided a novel form of roller head which comprises three rollers with their axes parallel, and the roller head is carried by a suspension bracket. When the suspension bracket is lifted for the hooking of the roller held between the rails, the head takes up a position in which it can be inserted between the rails, but when the suspension bracket is performing its function suspending a load, the roller head swivels so that a pair of rollers run on one rail, and the third roller engages the other rail, and as the rollers preferably are diablo rollers, the head effectively becomes locked between the rails, keeping the trolley on the rails, until such times as the suspension bracket is again lifted.
