A moveable lifting transmitter includes a main support structure (10) which is arranged on a track (11) and which can move along an upper sidestep surface (14) when in use, and a lifting transmitter (13) which is supported on a cantilever (12) which can be extended out of the structure from the main support structure internal contraction position. The cantilever comprises a plurality of cantilever trusses (22); when being extended and being contracted, the cantilever can pass a guide frame (29) bending externally and downward and arranged on the main support structure. The lower edge of the cantilever is connected by a gemel (23), in order to make the cantilever can bend to a lower sidestep surface (15) when passing the guide frame. The main support structure is provided with a material collecting transmitter (38) which can transmit the material from the lifting transmitter to the material releasing point. |
