Abstract
The method of radio communication between columns of a lift allows for use of a bridge consisting of at least two lifting columns and simultaneous operation of several bridges in a multichannel mode. The radio channels are selected in a pre-determined frequency band. The bridges synchronize respective columns in the course of the lifting operations and in the event of a fault in at least one column or in the event of an emergency stop. The method includes a first phase of triggering waiting and scanning, followed by a second phase of inscribing the columns for the construction of the bridge, and followed by a third phase of exploitation in the course of which each column of a constructed bridge dialogs with the others in the radio broadcasting mode, with an equal weight for all the columns.
