In addition, dual lifting cylinders provide superior comfort and stability, while also maintaining true vertical rise which prevents drifting forward or backwards.

Hire a 21m working height articulating knuckle boom in Auckland — 12m outreach for high maintenance and construction. Delivery available. Call 0800 467 009.
Our biggest knuckle boom, the 21m class handles the high, awkward reaches — over rooflines, plant and structures — that define serious maintenance and construction access work. The Skyjack SJ63AJ delivers a 21.4 m working height (19.4 m platform), 12.2 m of horizontal outreach and 8.4 m of up-and-over clearance.
Its open-centre knuckle riser design gives excellent visibility and even below-grade reach, while dual lifting cylinders provide true vertical rise without drifting — a real help when tracking a wall or column. Zero tail swing and continuous 360-degree rotation keep it workable in confined positions. Typical work: multi-storey exteriors, warehouse and stadium maintenance, services and steelwork around obstructions. If you don’t need the up-and-over geometry, our 22m telescopic boom gives more straight-line outreach for similar money.
We deliver by transporter throughout Auckland. Call 0800 467 009 to talk through heights, outreach and ground conditions.
