Abstract: A combined ramp and chocking construction for a four-wheeled vehicle can be adjusted to a first position in which the construction forms a ramp, and to a second position in which the construction provides four vehicle chocks. The construction includes four units arranged sequentially two and two in the longitudinal direction of the vehicle. Each of the units is elongate and pivotal about an axis that is perpendicular to the longitudinal direction of the vehicle. Each unit is also intended to be generally straight in the first position and generally angled in the second position, in response to rotation about their pivot axes.

Abstract: A spot welding rod for resistance welding of object comprises a rod which is moveable axially, and two electrode arms provided with electrodes, wherein the electrodes face towards each other and the welding gun is adapted to press together objects to be welded located between the electrodes by axial movement of the rod, and to allow welding current to flow between the electrodes. The rod axis extends in a direction which is generally perpendicular to the directions of the electrodes and at least one of the electrode arms is pivotally mounted. The welding gun includes structural elements which are connected operatively to the at least one pivotally mounted electrode arm and the rod.
