The Sumner Roust-A-Bout enables one man to lift and place loads in tight locations that would be impossible with other lifts. The flexible Roust-A-Bout not only makes the job possible . . . it can pay for itself in days by reducing job time!
This dependable lift can raise a 1,500 lb. (680 kg) load to heights up to 25 feet (7.6 m) in minutes. In addition, large 8" (200 mm) casters permit a fully loaded Roust-A-Bout to position pipe or beams with ease.
Wider loads up to 1,000 lbs (455 kg) can be handled with the addition of Sumner's Tee Head Extension Bar. The Roust-A-Bout eliminates the need for many other tools such as come alongs, scaffolds, monorails, and swing booms.
