Abstract
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.
Claims16
A radio-control antenna support device, comprising
- a support arm that can be pivotally mounted to at least one of a lower frame or a lower chassis of a tower crane, the support arm including
- a head upon which is mounted at least one radio-control antenna for radio control of the tower crane,
- wherein the head is radially offset from a vertical pivoting axis of the support arm, and
- the support arm can be oriented about the vertical pivoting axis and can be positioned in at least two separate angular positions.
