Abstract: This invention provides a conveyer comprising overhead rails mounted on pendant supports, and a load carrying device running on the rails. The supports each have a pair of downwardly extending arms which carry bolts that are fixed to the rails. Each rail has a groove opening on the side opposite to the guiding surface. Each pair of arms has inwardly projecting horizontal extensions at their lower ends. Each rail has at least three horizontal limbs and a vertical limb, the first limb having its upper surface serving as a bearing surface for the load carrying device and its lower surface bearing on an extension of one of the arms; the other horizontal limbs carrying flanges to contain T-shaped heads on the bolts which can be inserted at right angles to the length of the rails.
