From simple outriggers and davits to rolling carriages and soaring towers, the structural support frames from which monorails or Work Platforms and their companion material loads are often suspended are a key part of GBL’s Work Access systems. Support frames often employ single or multiple hoisting motors, and are themselves designed to provide and allow worker access as needed. Support frames may be mobile or fixed, counterweighted or anchored, and may roll along temporary GBL tracks or permanent window washing tracks. Throughout GBL’s history, a variety of ingeniously designed custom support frames have been utilized to solve problems, streamline processes, and increase productivity.
