Personnel safety beam in elevator shaft - The Building Code Forum
2018年2月12日 · The elevator hoist beam CAN be used as a hoist / platform tie off and a personnel tie off as long as its designed to meet to loads and requirements of both uses. In the end its cheaper to add a several hundred dollar piece of 5”x5” HSS tube steel than to pay a structural engineer to run the calculations.
Elevator support design forces - Structural engineering general ...
2000年11月29日 · In my experience, elevator support design forces (hoist beam, guide rail, pit slab, etc.) are sometimes difficult to obtain during the design phase. Some elevator suppliers do not want to give out this information before they have a contract to supply the elevator. That leaves the structural...
