Abstract

The articulated rotary boom (17) for a bridge crane has a beam (13) that supports a boom (17) which pivots around a centrally located vertical pivot (14). The boom comprises two parts (18, 118,218) which can be positioned vertically with respect to each other by cylinder and piston arrangements (121, 221). The boom is anchored by first portion (18) to rotary platform (24) which can oscillate and move by cylinder and piston arrangement (21). A motor unit (16) is also positioned around the central platform and is offset to the boom to act as a counterweight.
