ABSTRACT:
A hose bridge for bridging a hose extending over a surface, for example a fire hose for conveying water for extinguishing purposes, has a passage for the hose and defines a support surface that can rest on the surface. The transverse dimension of the passage in a direction transverse to the support surface is smaller than the nominal diameter of the hose and the circumferential dimension of the passage essentially corresponds to the circumferential dimension of the hose.
