Abstract

A hydraulic crane (10) comprises a centre post (12), which is rotatable around a vertical axis (21), a crane boom (13) having at least two sections (14, 15, 16), which are pivotally connected to each other and have mutually parallel horizontal pivot axes (22, 23, 24), and a lifting fork (29) pivotally connected to the outermost crane boom section (16) by means of a bearing housing (30), which is adapted to pivot around a horizontal axis (32) and in which the lifting fork (29) is rotatably mounted by means of a supporting shaft (31) extending perpendicular to said pivot axis (32). In order to make the crane as a whole more flexible, the pivotal position of the bearing housing (30) is separately adjustable, and the lifting fork (29) is arranged for limited tilting movement relatively to the supporting shaft (31) around a tilting axis (38) perpendicular to said shaft.
