A method for alignment of a vehicle and a levelling bench arrangement in relation to one another is disclosed, wherein the levelling bench arrangement comprises a levelling bench (), a support structure (), a plurality of beams (), and a plurality of fixture devices (). According to the method the support structure is arranged on the levelling bench, at least some of the beams are locked to the support structure, at least some of the fixture devices are releasably mounted at the beams, a vehicle, which is to be repaired or inspected, is arranged above the levelling bench, the mounted fixture devices are aligned with respect to the vehicle by means of continuously moving the beams and the support structure in a horizontal plane so that the fixture devices will define certain specific reference points of the vehicle and the beams are releasably fastened to the levelling bench.

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.

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. The structural elements are disposed between the point at which the one of the electrode arms is pivotally mounted and the electrodes and mutually engage one another and move translatively relative to each other and therewith force at least one of the electrodes towards the other electrode through the medium of a wedging action as the rod is moved axially.

Spot welding gun and a gun accessory

A method and apparatus for resistance welding of objects ( ) by a spot welding gun which has a C-shaped arm ( ), a front electrode ( ), a back electrode ( ) and a pneumatic cylinder ( ). The back electrode is axially moveable a limited distance by the cylinder. The gun is arranged to clamp the objects between the electrode tips ( ) by the cylinder ( ) and to provide a welding current to flow between the tips. The back electrode is arranged to be released from, moved axially in relation to, and fastened to the cylinder to enable or simplify positioning the gun so that the electrodes are on each side of the objects, removal of the gun from the welded objects and adjustment of the electrode distance (a) based on the thickness (t) of the objects.

The present invention relates to a device for supporting a heavier hand-held tool, particularly a spot welding gun, comprising a tool stand provided with a support arm arrangement mounted thereon, and a constant force spring having a first end and a second end, said first end of the constant force spring being attached to said support arm arrangement, and said hand-held tool being hung from said second end of the constant force spring, wherein the constant force of the spring is such that a user of the hand-held tool is relieved from at least a substantial portion of the weight of the tool, and the drawn-out length of the spring is long enough to enable the tool to be hung in a plurality of different operation heights. Preferably, the constant force of the spring is such that the tool is hung in a weight-balanced state. A line element may be connected between the constant force spring and the tool.
