    摘要: Disclosed is a mobile robot adapted to traverse vertical obstacles. The robot comprises a frame and at least one wheel positioned in a front section of the robot, at least two middle wheels and at least two rear wheels. The at least one middle wheel and at least one rear wheel are connected by a tilting lever that is arranged on each of the opposing sides of or to the frame, forming a pair of wheels. Each tilting lever can be turned around a lever bearing located between the respective axial centers of rotation of each pair of wheels.

    摘要: A center link has a bolt portion contact pad extending longitudinally and transversely from the bolt portion, forming a bolt portion contact surface extending transversely, and defining a bolt portion contact surface transverse width that is less than the shaft portion transverse width. The center link also has a mushroom head portion contact pad extending longitudinally and transversely from the mushroom head portion, forming a mushroom head portion contact surface, and defining a mushroom head portion contact surface transverse width that is less than the shaft portion transverse width.

    摘要: A crane, in particular a pick and carry crane, may have a front chassis with front wheels and a back chassis with back wheels, the front chassis being articulated relative to the back chassis so that the crane can travel whilst carrying a load suspended from a boom. The back and front wheels have independent suspensions which are capable of connection to one another so that movement of a left wheel influences movement of a right wheel, thereby improving the handing of the crane, particularly over rough terrain.
