Articulating Boom LiftA-1550

The A-1550 uses a jointed, articulating (knuckle-boom) boom rather than a straight telescopic boom, so the platform can fold up and reach over obstacles instead of only extending in a straight line. The hexagonal boom sections are high-tensile steel (min. YST 700 N/mm2) with self-lubricating pivot points and plasma/laser-cut profiles, each joint driven by a double-acting hydraulic ram with a horned tube and an induction-hardened, chrome-plated rod. A side-boom control layout lets the operator move any boom section at any angle with no fixed operating sequence, and the FRP cage allows direct entry from the chassis deck. Four hydraulically operated stabilizers must be extended and locked before the boom can be raised, enforced by a boom-stabilizer interlock, and they lock automatically once the machine is open. The turntable slews a full 360 degrees continuously on a worm-reduction slew bearing, and a mechanical parallel-linkage leveling system keeps the cage level throughout the boom's motion. The whole platform is designed to the EN280 safety standard, with a European-brand PLC controller integrating the safety interlocks. A 3kV insulated bucket is available as an option for electrical maintenance work.

The A-1550 delivers a 15.5m working height with a 13.5m platform height and 6m of horizontal outreach, rated for a 200kg safe load, with 360-degree continuous slewing. It mounts on a 7-ton GVW truck chassis, making it the flagship of Maniar's articulating boom lift line, which spans 10m to 15.5m working height across five models, mounted on chassis ranging from a compact truck up to 7-ton GVW.
