A SAFETY ENHANCED TURNTABLE OR FIFTH WHEEL FOR COUPLING A SEMI-TRAILER TO A PRIME MOVER

摘要

Abstract A method for assisting in the coupling of a semi-trailer to a turntable of a prime mover includes remotely monitoring sensors about the turntable to make a number of determinations. These include that the semitrailer is suitably close to the turntable for correct coupling. That a locking member, e.g. a kingpin, of the semitrailer is correctly positioned relative to the turntable for proper coupling and that a kingpin locking mechanism of the turntable is in a locked configuration. The result of the determinations is indicated to an operator of the prime mover. Consequently the operator is able to readily ascertain that a correct coupling has been achieved. 0) co 04 CD Co .0e4 V 1'V %ale LOi 10e 0a) 0)
