Abstract
Improved tower crane, which is constituted from a movable bedplate, for example, on rails, in which a platform is mounted in a rotating manner in which the reticulated structure of the crane is supported, constituted such a structure by the column or tower and the corresponding pen; essentially it is characterized in that the column or tower consists of two sections, a lower one with a point of articulation and another one of fixation to the rotating platform, and an upper section that receives the articulated anchor of the rear end of the pen with the aforementioned two constituent sections of the column or tower articulated to each other and combined such articulation with a locking device that fixes the positioned, within a vertical plane, of both section as well as also fixes the point of articulation of the lower section of the column or tower to the rotating platform, said locking device consisting of, for example, triggers operated from the control panel or load lifting mechanism, which also commands a drum connected to a trocola and a set of six cables through which it is passed, in a fully automatic way, from a folded crane (transport position) to a folded crane (working position) and cease (Machine-translation by Google Translate, not legally binding)
