How to Maintain a Digital Crane Scale

A digital crane scale, while ruggedly constructed to perform heavy lifting and weighing functions, is also a precision instrument that must be maintained on a regular basis.  While maintenance is important for any weighing instrument from an accuracy standpoint, heavy-duty crane scales must be checked regularly to avoid a mechanical failure that could cause a load to drop with potential disastrous results.
