The invention relates to radio-control of lifting machinery, and is intended to solve problems due to the presence of interfering metal masses. For this purpose, the support arm of the radio-control antenna is mounted such that it is able to be orientated about a vertical pivoting axis, on the lifting, machinery. This support arm includes a head, radially offset with respect to the axis, upon which the antenna is mounted. The support arm can occupy separate angular positions, and in particular a position in which the antenna is separated from the metal structure of the lifting machinery. This invention applies in particular to the radio-control of tower cranes.

Radio-control antenna support arm for lifting machinery

The crane comprises a mast ( ), mounted on a chassis ( ), and a distributor jib ( ) composed of successive elements ( ) articulated on one another about horizontal axes ( ), the first jib element ( ) being articulated about a horizontal axis ( ) on the top of the mast ( ). The first jib element ( ) and, if appropriate, the following element ( ) can be brought into a substantially vertical position in alignment with the erected mast ( ), so as to increase the height of the mast. All the jib elements ( ) comprise a rolling track ( ) for a carriage ( ), and these elements can be used in various positions (B, F). A crane with modifiable configuration is thus obtained.
