  • Unidirectional bend drive chain and lift mechanism and boom barrier including same
    Patent number: 9945083
    Abstract: A unidirectionally bendable transmission chain. At a first side thereof, an inner stop plate is fixed between a pair of inner chain plates at both ends of pin shafts, and an outer stop plate is fixed between a pair of outer chain plates at both ends of the pin shafts. Both ends of the inner stop plate are flush with axes of pin holes provided at both ends of the inner chain plates, and both ends of the outer stop plate are respectively provided with extensions beyond the outer chain plates; the extensions of the outer stop plate form a one-sided support for the inner stop plate to prevent the transmission chain from bending toward the first side, thus the transmission chain bends unidirectionally toward a second side opposite to the first side. A hoisting mechanism and a liftable roadblock having the above transmission chain.
