JLG 800 expert review
Overview
This model is built for large construction sites, industrial maintenance, and infrastructure projects that require significant height and reach. Its articulating jib and up-and-over capability make it ideal for working over obstacles like parapets and pipe racks. The chassis and drivetrain handle uneven ground well, and proportional controls make basket positioning precise at full extension.
Durable powertrain and large platform with straightforward service access.
Higher fuel consumption and maintenance costs than mid-class booms.
Performance & Efficiency
Smooth proportional controls improve accuracy at height, and the 130° jib articulation helps work above structures without frequent repositioning. The 45% gradeability keeps it mobile on ramps and compacted backfill. Accessible service points and modular components support efficient fleet maintenance.
In Comparison
Against rivals like the Genie Z-80/60 (~25.77 m platform height, ~18.29 m outreach, ~227 kg capacity), the JLG 800 AJ trades slightly shorter outreach for a tighter up-and-over clearance and stable platform feel.
Verdict
If your work demands dependable height, reach, and load capacity, the JLG 800 AJ is a proven performer. It requires thoughtful logistics, but it excels in productivity and operator confidence on tall, challenging jobs.
