  • Publication number: 20250189019
    Abstract: This construction equipment includes at least one electric actuator to generate a relative movement between a first element and a second element of the construction equipment, including at least an electric motor for driving a carriage in translation according to a longitudinal axis, a connecting rod that is articulated at one end on the carriage and that is articulated on the other end to the first element, a guiding system for guiding the carriage in translation parallel to the longitudinal axis and a support member to which is fixed the guiding system. Two end fittings are provided respectively at the two longitudinal ends of the support member and connect the support member to the second element: A first end fitting is configured so that said second element can freely expand or contract along the longitudinal axis relative to the support member, and inversely.

  • Patent number: 12291838
    Abstract: Construction equipment includes a framework and at least one electric actuator for moving at least one element of the framework. The actuator includes a ball or roller screw system having a threaded rod and a nut forming a helical connection with the threaded rod. An electric motor drives the rod in rotation around a longitudinal axis, forcing the nut to move axially along the rod. A carriage is axially connected with the nut. An axial guide guides the movement of the carriage. The guide is fixed to the framework. At least one support element connects, directly or indirectly, the threaded rod to framework. The support element is designed so that threaded rod can tilt, to some extent, relative to framework around any axis perpendicular to rod longitudinal axis.
