One Source Equipment Rentals has electric powered towable boom lifts for rent or sale from JLG, and Genie. These aerial work platforms are great for contractors that frequently move between jobs like tree services and utility contractors. Towable boom lifts have a 2 piece knuckle boom which allows for an up and over movement over obstacles. They come in platform heights from 49′-6″ up to 50′-9.5″ with a 500-pound capacity. They utilize auto-leveling hydraulic outriggers for leveling on uneven surfaces. For self-propelled and rough terrain models, see articulated boom lifts.
