Abstract: An improved base is provided for supporting conventional mobile scaffolding commonly used to erect and maintain buildings. The components of the base according to the present invention may be easily stored and transported to the jobsite, and then quickly and reliably assembled in a manner which decreases the likelihood of improper or unsafe assembly. The safety of personnel utilizing such scaffolding is substantially increased by providing a plurality of stop members fixedly secured to the assembled base, with each stop member extending downward and terminating a selected distance above the ground engaging surface of a roller. At least two stop members are provided for each of the base corner rollers, and each stop member is preferably positioned adjacent a line extending between two corner rollers.

Abstract: A male/female connection of the twistlock type is provided for coupling vertical scaffolding members. Both the male and female components are forged, and the connection components may be reliably welded to respective tubular scaffolding members or standards. The safety of the scaffolding is improved compared to mechanically crimped connections, and the cost of scaffolding field repair and maintenance is substantially reduced.
