80ft JLG 800AJ DIESEL KNUCKLE BOOM

The JLG 800AJ is a large diesel-powered articulating knuckle boom lift with a working height of 26.38 m (86 ft) and a platform height of 24.38 m (80 ft). With a horizontal reach of 15.74 m (51.6 ft) and a platform capacity of 230 kg, it is engineered for heavy-duty elevated access on major construction, industrial, and infrastructure projects. The articulating boom design, combined with a 130-degree jib articulation range, allows operators to position the platform around structural obstacles and into confined overhead spaces that telescopic booms cannot reach.

What distinguishes the 800AJ from smaller articulating booms is its 4WD/4WS drive system with selectable two-wheel and four-wheel steer modes, giving it the manoeuvrability to work on congested job sites despite its 15,600 kg weight. Foam-filled tyres, an oscillating axle with 0.2 m of travel, and 45% gradeability in 4WD make it capable on uneven ground typical of large civil construction sites. Continuous 360-degree swing and a stowed height of just 3 m also make site relocation and transport straightforward.

In the Geelong region, the 800AJ is the machine of choice for major industrial and civil contracts — wind farm maintenance, bridge and highway construction, large-scale commercial builds, and refinery or petrochemical shutdowns where maximum reach and outreach are required simultaneously. It pairs well with riggers, steel workers, and services contractors who need a robust, self-powered platform that can be repositioned repeatedly across a large work front.
