Реферат: The mast foot coupling is based on the conventional universal coupling comprising opposed forks at right angles connected via a coupling-block. This block (12) which has adjoining holes at right angles for pins (7,8) through the fork arms (3,4) has filling pieces (15,16) projecting from its free surfaces, perpendicular to each other and extending T-wise beyond the block faces. Filling-piece overall length is pref. equal to fork width, and fork-base and facing filling-piece-surfaces (21,22) are configured to keep the gap between (19) constant in operation. Fork arm head- and mating filling-piece-surfaces (24,25) are shaped for rolling contact in operation.
