摘要： 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.

摘要： 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.
