Davits are devices, used singly or in pairs, for suspending powered platforms on a building for the purposes of performing exterior maintenance—such as window washing—or construction-related activities. Unlike outriggers, davits react their operating loads into roof sockets. The components of a davit installation usually consist of the davit base, which is permanently attached to the building; a socket, which may be portable; and a portable davit arm. In the context of this article, the davit arms, bases, and sockets are referred to as a davit installation. Often, structural engineers are tasked with designing the building roof structure to resist davit loads.

The purpose of this article is to present a general overview of design, testing, and inspection requirements needed to provide certification of a davit installation to a building owner. The design and certification requirements for davit components are regulated by Occupational Safety and Health Act (OSHA) standards.
