ABSTRACT:
A castor assembly for a scaffold tower or similar structure needs to be provided with a brake. In this construction the brake comprises various forms of rotary cam, e.g. an eccentrically-mounted cylinder, a lobed cam and preferably formed with one or more ribs for gripping purposes. The cam may be in contact with the wheel to remove grit, etc. On movement of the wheel and wheel carrier into the braked position the cam pivots into a position where it is wedged between the swivel of the castor assembly and the wheel periphery. Thus movement of the assembly about the vertical swivel axis and rotation of the wheel about its horizontal axis is prevented.
