Abstract
An aerial lift platform apparatus has a wheeled chassis, a turret on the chassis and a boom pivoted to the turret. The wheels are carried by extendable axles, to provide increased stability. The boom is depressed to raise at least one wheel, to permit its extension and retraction. Preferably, there are four wheels on two axles, and the wheels of each axle are successively raised and then extended or retracted.
