Improvement relating to load- carrying carriages which run on tracks

摘要

The carriage (which is suitable for a mobile storage unit or for an overhead travelling crane) has its body 1 supported on wheels 2 between which and the body relative vertical movement is allowed. The wheels are normally urged downwards relative to the body by means of resilient pads 20 of rubber or plastics material located between fixed supports on the body and rigid plates 19 resting on non- rotatable axes 3 of the wheels. In the form shown each plate 19 and pad 20 is flat. In an alternative form each compression pad is of angle section disposed centrally over the respective axle with its flanges tangentially straddling the axle. Either a resilient pad of complementary angle section is located to engage with the two flanges of the compression pad, or there are separate resilient pads for the flanges. IMAGE
