ABSTRACT:
An apparatus for supporting and transporting of heavy loads, especially metallic profiled-bars and the like which have at least a U-shaped bearing block. The bearing block has a foundation and two side parts, each having a suspension, attachment or mounting bracket provided thereon. Supporting arms provided on a traverse engage the attachment, suspension or bracket. For that, the attachment, suspension or bracket of the bearing block can have a structure as closed support rings, hooks or eyelets with two legs or arms inclined in a roof-shaped configuration. One of these legs or arms additionally in a plane transverse to the longitudinal direction of the foundation has such an offset relative to the other leg or arm, that a suspension free space is formed for a positively-guided engagement of the supporting arm.
