Boom lifts (cherry pickers) are self-propelled aerial work platforms with articulating or telescoping booms. Maximum heights typically range from 40 to 135+ feet. Typical rental costs range from $50-$250 per day depending on height and type. These lifts are ideal for exterior work: window washing, signage installation, facade work, and tree trimming. Platform capacities typically range from 500 to 1,500 pounds. Boom lifts can access areas that stick-built scaffolding cannot reach. They require trained operators and are subject to OSHA aerial lift requirements. Common fuel options include diesel, gasoline, hybrid, and electric. Outreach capabilities range from 10 to 100+ feet horizontally. Safety features include emergency descent systems and platform guards. Modern lifts include jib attachments for horizontal extension.
