本手册共32页，由美国起重机制造商协会工程委员会编制。桥式或龙门起重机的操作不仅仅涉及起重机的控制操作。操作者必须考虑和预见由于操作控制而发生的运动和动作。规范79还列出了起重机操作员所需的资格，以及操作员的“应”和“不应”。

This 32-page manual has been prepared by the Engineering Committee of the Crane Manufacturers Association of America, Inc. Operation of an overhead or gantry crane involved more than operating the controls of the crane. The operator must consider and anticipate the motions and actions that will occur as a result of operating the controls. Specification 79 also lists qualification required to be a crane operator, as well as "shall and shall nots" for operators.
