AbstractA weighing method for a wheel supported load, such as a hospital bed, uses a weighing device having a base with a flat bottom surface, and a track surface for a wheel arranged parallel to the bottom surface. The track surface is supported on an arrangement for sensing weight which includes a pair of cantilever bending beams with strain gages, and one end of the track surface extends beyond the end of the flat bottom surface. To start weighing, the weighing device is first tilted, so the track surface can be wedged between a wheel and the floor. In this position the track surface acts as a ramp for the wheel. The wheel is next rolled up onto the track surface until it is above the front edge of the flat bottom surface. At this point the weighing device will flip over by gravity to rest on the flat bottom surface, and the weighing of the load can be done without risk for force shunting to the floor. A weighing device suitable for use with the method is also disclosed.
