Self-propelled stair climber

Self-propelled stair climber for goods comprising:

• first and second tracks motorized and having an elongated configuration parallel to a straight forward travel direction of the stair climber;
• a loading surface implemented to tilt with respect to the tracks around a first transverse axis, perpendicular to the tracks;
• an actuated stabilization member movable between an extracted position so that the weight of the stair climber is carried at least in part by the stabilization member and a retracted position in which the stabilization member is not loaded by the weight of the stair climber;
• a proximity or support sensor carried by the stabilization member to send a signal of approach or contact with a floor;
• an electronic control unit programmed to:
• activate the first and second tracks on the basis of the signal when the stabilization member is extracted;
• and
• check an inclination of the loading surface so that the inclination is maintained in a predefined angular range with respect to a horizontal direction;
• said stair climber further comprising a hollow support structure to which the loading surface is hinged and connected to the first and second tracks, in which a first actuator is housed to control the inclination of the loading surface and a second actuator to control the stabilization member;
• wherein the first and second actuators are arranged so that, when in a retracted configuration, they are flanked by the first and second tracks, wherein the control unit is programmed in a descent-start mode so that the stabilization member is extracted to raise a proximal portion of the tracks, being a distal portion of the tracks facing the descent, and the tracks are operated to descend the descent and such that the stabilization member is brought into the retracted position automatically when a pre-set condition is satisfied or a signal is generated by a sensor, the pre-set condition and/or the signal being representative of a state of the stair climber in which the tracks contact edges of two adjacent steps.
