United Rentals carries a complete range of telescopic boom lifts for construction, mechanical contracting, painting, glazing, electrical work and industrial maintenance. Straight boom lifts can be raised, lowered and extended horizontally while the work platform remains stable and straight. You can maneuver and steer in any direction, even while the platform is extended. Four-wheel drive and 45% gradeability make driving the boom lift smooth and easy, so it's ideal for moving around outdoor jobsites.
