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.
