DYNAMICS TROLLEYS
The trolley consists of a rectangular wooden body carried upon three low-friction plastic wheels and is supplied with one strong spring plunger and three dowel pegs.
Several trolleys may be stacked on top of each other and are held in position by holes drilled underneath which fit over dowel rods placed in corresponding holes in the upper surface of the lower trolley. This enables the effective mass of a trolley to be increased to two or three times its basic mass. Sufficient space is provided on the flat of the trolley for the addition of heavy loads.
Dimensions 290x140x90mm.
