Gorbel Work Station Cranes are designed with an adequate safety factor. If you over-buy capacity, the operator will need to move extra bridge dead weight, which would not be a good ergonomic solution. Keep bridge lengths to a minimum. The less dead weight an operator has to move, the better. Short bridge lengths are better for higher-cycle production areas.
Longer bridges are acceptable for lower-production cycle or maintenance areas.
Can the operator safely move the load. To help determine if your worker can safely move the required loads, refer to Increasing Productivity and Safety in Manual Overhead Bridge Crane Operation by Shealy and Stibitz 1993, which is available through your Gorbel Dealer.
