ELEVATOR LOAD BEARING ASSEMBLY INCLUDING DIFFERENT SIZED LOAD BEARING MEMBERS

摘要

An elevator system ( 20 ) load bearing assembly ( 30 ) includes a plurality of load bearing members ( 32 - 38 ). At least one of the load bearing members ( 32 - 38 ) has a load carrying capacity that is different than at least one other of the load bearing members ( 32 - 38 ). A disclosed example includes equal numbers of load bearing members ( 32, 38 ) having a first load carrying capacity and equal numbers of load bearing members ( 34, 36 ) having a second, different load carrying capacities. Another example includes at least three different load carrying capacities. With the disclosed examples, the aggregate load carrying capacity of an elevator load bearing assembly ( 30 ) can more closely meet the load carrying requirements for a given elevator system without over-roping the system.
