  • Lifting assembly
    Patent number: 9315365
    Abstract: A pull chain moving assembly is designed to impart directional force on an endless-loop pull chain of a chain hoist. The assembly has a housing retaining a chain moving mechanism, which includes a chain pocket wheel and a pair of idler pulley assemblies mounted on opposite sides of the chain pocket wheel and adjacent thereto. Segments of the pull chain are received between the chain pocket wheel and the adjacent idler pulley guide, causing the pull chain to train through the chain moving mechanism. An electric motor rotates the chain pocket guide to facilitate movement of the pull chain and ease of lifting and lowering a load with the chain hoist.
