SWIVEL BOOM - MEDIUM DUTY

The medium duty Swivel Boom assembly is used on transmission structures to lift and move the insulator cradle and insulators into a convenient work position on the structure. The 3" round Epoxiglas® horizontal boom and vertical mast are designed for 500 pound ratings when used in a steel tower configuration and 600 pound rating for wood pole assembly.

An insulated link stick and a hoist are used in a diagonal position to lift the cradle full of insulators clear of the deadend strain poles and other obstructions.

For tower use, three boom support poles should be added in a tripod configuration as shown in the illustration at left below.
