New type building cradles are demonstrated at Maidenhead.
Various shots of workmen on field demonstrating the ease in which these new type of building cradles are erected. The men give a demonstration of how the manually operated cradle raises in its own hoist. They get in and lift themselves up manually. Various shots as the motor driven cradle is demonstrated against the side of a two storey building. We see the electric powered motor on roof of building and the cradle being raised.
