Choose the Z-45/25J RT if...
A widely hired rough-terrain boom for construction and outdoor maintenance. The articulating up-and-over jib is what separates it from a straight telescopic boom: it reaches over an obstacle rather than only to it, which is often the entire requirement.

The JLG 450AJ is a mid-size diesel articulating boom lift used across UK construction, industrial and outdoor maintenance sites where working height above 15 m and rough-terrain capability are both needed. It is one of the most commonly hired boom lifts of its size class in the UK, stocked alongside comparable Haulotte and Genie models by national access hire companies. Its jib articulation lets operators reach up and over obstacles rather than just straight out, which is valuable on cluttered industrial sites.
