125ft JLG 125AJ DIESEL KNUCKLE BOOM

The JLG 125AJ is a large-capacity diesel articulating knuckle boom lift delivering a working height of 40.3 m (132 ft) and a platform height of 38.3 m (125 ft), with a horizontal outreach of 19.25 m. The platform carries 227 kg, allowing one or two operators to work with tools and materials at significant height. Powered by a robust diesel engine, it is built for outdoor use on construction sites, industrial facilities, and infrastructure projects where extreme height access is required.

What sets the 125AJ apart from mid-range knuckle booms is its combination of extreme vertical reach and substantial horizontal outreach in a single machine. The articulating jib gives operators the ability to reach up and over obstructions — facades, structural steel, and roof overhangs — that would defeat a straight telescopic boom. The four-wheel-drive chassis with rough-terrain tyres handles uneven ground and graded surfaces, making it practical on active construction sites rather than just finished surfaces. At this height range there are few alternatives outside of a crane, and the JLG 125AJ provides that same reach at a fraction of the mobilisation cost and setup time.

In the Geelong region, this machine is well suited to large commercial and industrial builds, bridge maintenance, powerline and telecommunications work at height, and high-bay facility construction where access from ground level is simply not possible with smaller equipment.
