51ft JLG 510AJ DIESEL KNUCKLE BOOM

The JLG 510AJ is a diesel-powered articulating knuckle boom lift with a working height of 17.81 m (58 ft), a platform height of 15.81 m (51 ft), and a horizontal reach of 9.48 m. With a 230 kg platform capacity, it is suited to two-person work at height, making it a practical choice for construction, infrastructure maintenance, and industrial applications where both height and horizontal positioning are required.

What sets the 510AJ apart from smaller articulating booms is its 7.67 m up-and-over clearance, which allows the boom to reach over parapets, structural steel, and roof edges without requiring repositioning of the machine. The diesel drive system and four-wheel drive capability make it well suited to outdoor, rough terrain, and uneven ground conditions common on Australian construction sites. Its compact transport width of 2.34 m allows it to be moved between sites without the need for a specialised wide-load permit, and the machine can negotiate site access gaps that would restrict larger boom lifts.

In the Geelong region, the 510AJ is regularly used for steel erection, cladding installation, commercial roofing, and maintenance work on industrial buildings and warehouses. Its combination of reach, up-and-over capability, and outdoor performance makes it a versatile choice across the construction and infrastructure sectors in Victoria.
