Abstract

A crane for lifting and transporting loads includes a base frame, capable of transferring the loads onto a support surface. A sliding element is slidably constrained to the base frame. An arm capable of moving the loads is hinged to the sliding element. A connection element has a first end hinged to the sliding element, and a second end constrained to the base frame in a mobile manner. Each of a pair of rod elements is hinged to the base frame and to the connection element to form an articulated quadrilateral. A first linear actuator is hinged to the base frame and to the connection element and capable of causing sliding movement of the sliding element relative to the base frame. A second linear actuator is hinged to the sliding element and to the arm capable of causing mutual rotation movement between the arm and the sliding element.

Dependent claims

A crane for lifting and transporting loads, comprising:

a base frame for transferring loads of the crane onto a support surface by wheels arranged in contact with said surface;
a lifting mechanism to lift and transport loads associated with said base frame;
a roll-over protection system comprising:
a first portion and a second portion of the base frame, mutually hinged to one another and rotating around a hinge, the first portion and the second portion being also constrained by at least one elastic element;
and
a control system for detecting a mutual position between the first portion and the second portion and of carrying out predetermined tasks of the crane when said mutual position reaches a threshold condition;
wherein the deformation of the at least one elastic element is linked to a mutual angular position of the first portion and the second portion;
wherein the first portion and the second portion of the base frame are constrained for rotating only around the hinge, wherein said rotating corresponds to a greater or smaller elongation of the elastic element.
