The JLG 340AJ Articulating Boom Lift delivers versatile performance for indoor/outdoor jobsites where maneuverability and reach over obstacles matter. Its compact size, oscillating axle, and 4WD system provide industry-leading terrainability, while the articulating boom and jib allow operators to access hard-to-reach areas efficiently. Steel hoods and a Tier 4-compliant engine help reduce ownership costs and improve durability.
