Traveling undercarriage for a container or the like

An undercarriage for a container, particularly an undercarriage equipped with an electrical, penumatic or hydraulic drive, comprising a substantially rectangular frame, said frame including two main supports which extend substantially parallel to one another and transversely with respect to the direction of movement of the undercarriage, means for interconnecting the main supports with one another at their ends, transverse supports extending between said main supports, rollers carried by the transverse supports, connection elements for detachably connecting the transverse supports carrying the rollers with the main supports, and attachment elements which can be suspended at the main supports at which there are connectable transverse walls of the container, and further comprising a protection beam arranged at least beneath one of the main supports and essentially parallel thereto, hinge connection means for connecting the protection beam with the transverse supports, and spring means for retaining the protection beam in a position protruding past the associated main support, said protection beam being displaceable against the spring force of said spring means in a direction transverse to its lengthwise direction when a force is applied to the protection beam in order to cut-off the drive.
