Abstract

"Improvements in cranes", especially tower cranes, which comprise a device for controlling the rotation of the rotating arms constituted by a circular crown coupled integrally to a ring or a frame arm and by a pinion coupled to this crown and dragged by an engine thanks to a reducer, characterized in that it comprises at least one reducer mounted and supported by the crown and not integral with the fixed part of the crane; this reducer is capable of making very small displacements with respect to said crown to maintain the pinion that is associated with it, always in constant coupling with this crown for all the positions and/or load of the rotating parts of the crane.
