Modular beam for a gantry and bridge, in particular rolling bridge and the gantry and bridge equipped with such a beam

摘要

The beam is designed to form the rolling track for the carriage of a lifting device. It is formed as a reversible assembly of two parallel cross beams (5, 6). Each beam is itself constructed as an assembly of pairs of modular elements (7), which are formed as standard size box elements, which can be fitted together end to end in a reversible manner.
