ABSTRACT:
Aspects of the invention provide a hoisting and lowering driving engagement multi-row chain in which the weight of the chain is balanced across the chain width direction so as to improve the load balance. This allows the weight of articles to be hoisted and lowered more stably hoisted and at higher positions, and results in an improvement of endurance of the chain, reduction of driving noise, miniaturization of the chain size, while the biasing or deflecting of intermediate tooth plates and inner tooth plates in the chain width direction is suppressed.
