Abstract (en)
[origin: CN104709832A] The invention relates to a jointing device (14) for bonding a first structural member (12a) on a second structural member (12b) of a tower crane, the device comprising at least one plate (26) extending since a base portion (34) connected to a flange (16a) of the first structural member (12a) by a main seam (70) to a connecting portion (38) which is adapted to be bonded to a flange (16b) of the second structural member (12b), characterized in that the base portion (34) of the splice (26) has a lumen (56) which is delimited by a peripheral wall connected to the frame (16a) of the first structural member (12a) by a secondary weld bead, to reduce the mechanical stresses on the weld seam.
