Abstract
A hanger bracket for trolley track rails is constructed of U-shaped formed pieces of sheet metal bolted together to provide both a clamping and a through bolt attachment to a rail mounting flange to simplify installation. The bracket is adapted to a pivot bolt mounting by a removable mounting plate received in slots in the formed pieces. Aligned holes in the formed pieces allow a hanger bar mounting, while the removable plate can also receive a swivel bolt. The formed pieces are interfit to be keyed together to insure shared loading of the rail flanges.
