CMAA专门制定了规范78，以将桥式起重机服务和相关起重设备的服务视为一个“行业”，值得制定由安全意识强、经过制造商培训和认证的技术人员提供高质量专业服务的指南和标准。随着规范78的引入，CMAA打算制定更高的性能标准，并提高客户对桥式起重机和相关起重设备服务的期望。

Specification 78 has been purposely developed by CMAA to recognize overhead traveling crane service and the service of associated hoisting equipment as an "industry" worthy of having guidelines and standards for providing high-quality, professional services performed by safety-minded, manufacturer-trained and certified technicians. With the introduction of Specification 78, CMAA intends to set higher performance standards and raise customer expectations related to the service of overhead traveling cranes and associated hoisting equipment.
