The SI 219 HDT-C telescoping boom lift has a 219-foot working height, 89-foot horizontal outreach, 360-degree continuous rotation, and up to 1,000-pounds capacity on its 7-foot platform. When used with a 5-foot platform and standard 900-pound-capacity material handler, which folds out of the way when not in use, says the company, total platform and material-handler capacity increases to 1,125 pounds.
