JLG 600AJ Boom Lift: Specs, Price and Buying Guide
Last updated: October 2026
The JLG 600AJ is a 60 ft articulating boom lift with a jib. It reaches a 60 ft 7 in platform height and 39 ft 9 in of horizontal outreach, and it can reach up and over obstacles as tall as 26 ft 7 in. That makes it a common choice on construction sites and industrial jobs where a straight telescopic boom can’t get around beams, pipes or rooflines.
This guide covers the 600AJ’s specs and features, how it compares to similar lifts, what it costs new and used, and what to check before you buy one.

Specs are for current production models. Older 600AJ units used different engines, such as a GM Vortec 3000 dual-fuel engine, and some weights and dimensions differ by year. A 600AJ Narrow version was also built for tighter spaces. Always check the data plate and the operator’s manual of the machine you are buying.
JLG 600AJ Key Features
- Articulating boom with jib: the “A” stands for articulating and the “J” for jib. The jib articulates 130 degrees, so you can position the platform over and around obstacles.
- Zero tailswing: the counterweight stays within the machine’s footprint when the turntable rotates, which helps next to walls and traffic.
- 360-degree continuous rotation and a 180-degree hydraulic platform rotator.
- Four-wheel drive and oscillating axle: 45% gradeability in 4WD and 8 in of axle oscillation for rough sites.
- Load sensing system: current models include JLG’s load sensing system with zero calibration, a tilt alarm and a platform status light panel.
- SkyGuard and ClearSky: SkyGuard SkyLine secondary guarding and ClearSky Smart Fleet telematics come standard on current models. SkySense enhanced detection is optional.
- Platform power: a 110V AC outlet at the platform, plus optional SkyPower, SkyWelder, SkyGlazier and SkyCutter packages.
How the JLG 600AJ Compares
Here is how the 600AJ compares with JLG’s 60 ft telescopic boom and Genie’s closest articulating models.
| Model | Type | Platform height | Horizontal outreach | Up and over | Capacity | FleetNow used prices |
|---|---|---|---|---|---|---|
| JLG 600AJ | Articulating with jib | 60 ft 7 in | 39 ft 9 in | 26 ft 7 in | 500 lb | $33,900 to $109,950 |
| JLG 600S | Telescopic | 59 ft 8 in | 50 ft 2 in | N/A | 600 lb (1,000 lb restricted) | $28,950 to $94,950 |
| Genie Z-62/40 | Articulating with jib | 61 ft 11 in | 40 ft 5 in | 25 ft 7 in | 500 lb | $31,850 to $127,550 |
| Genie Z-60/37 FE | Hybrid articulating with jib | 59 ft 7 in | 36 ft 7 in | 24 ft 3 in | 500 lb | $47,100 to $85,300 |
Choose the 600AJ when you need to reach over obstacles. If you need maximum straight-out reach or more platform capacity and have a clear path, the 600S telescopic boom reaches about 10 ft farther. The Genie Z-62/40 is the 600AJ’s closest competitor, with slightly more height and reach. The Z-60/37 FE is a hybrid that can run on battery power indoors.
JLG 600AJ Pros and Cons
| Pros | Cons |
|---|---|
| Jib and 26 ft 7 in up and over height reach around obstacles | 500 lb capacity is lower than the 600S telescopic boom |
| Zero tailswing makes it easier to work next to walls and traffic | About 10 ft less horizontal outreach than a 60 ft telescopic boom |
| 4WD and 45% gradeability handle rough job sites | At about 23,000 lb, it needs a heavy trailer to move |
| Very common in rental fleets, so parts, service and used units are easy to find | Slow 4.25 mph drive speed on large sites |
| Dual-fuel option for jobs where diesel is not allowed | Many used units are high-hour former rental machines |
Overall, the 600AJ is a versatile 60 ft boom for crews that need to work up and over obstacles more than straight out.

- Hours and records: check the hour meter, service records and the last annual inspection.
- Boom and jib: look for cracked welds, bent sections and play in the boom, jib and platform pins.
- Hydraulics: check cylinders and hoses for leaks, and make sure the boom holds position without drifting down.
- Controls: test every function from the platform and ground controls, plus emergency lowering.
- Safety systems: confirm the tilt alarm, load sensing system, foot switch and all-motion alarm work.
- Turntable: rotate a full 360 degrees and listen for grinding or rough spots in the swing bearing.
- Drivetrain: drive in 2WD and 4WD, test both steering modes and the brakes, and check the oscillating axle.
- Engine: look for hard starting, heavy smoke and warning lights, and ask for a fault code scan.
- Tires: check foam-filled tires for chunking and uneven wear.
- Platform: make sure the gate closes on its own, the lanyard anchors are intact and the decals and manual are present.
