US Capitol Flag Hoist Replacement Project
	Challenge:: On the roof of the US Capitol flags are flown, packaged, and given as gifts by Congressmen. A crane is needed to raise and lower carts of flags. The existing 1970s structure had a load capacity of 500 lbs. Although it had been load tested periodically, it was not OSHA compliant. Left unprotected, it aged outside causing safety concerns. Solution: The old structure was replaced with a Gorbel ‘Sleeve Mounted’ Freestanding Jib Crane with a ½ ton capacity. It was fitted with a Harrington Electric Chain Hoist and Motorized Trolley. The new design improvement increased capacity and reach. The Motorized Trolley provided superior hook positioning. The Power Rotation Drive offered more control and safety including ‘Soft’ Starts and Stops that eliminate swinging loads. A new foundation was built on the sub-roof level of the Capitol allowing a narrow footprint of the crane on the roof’s surface and thus more foot traffic near the mast. The structure was painted “US Capitol” White. Zenmar installed the system, performed a load test to ANSI standards and provided formal training for the operators.
