The JLG 1250AJP Ultra Series articulating boom lift is engineered for maximum productivity on demanding elevated work projects, such as construction, maintenance, industrial installations, and infrastructure tasks. Its advanced articulating design, combined with a JibPLUS® boom, provides exceptional up-and-over reach (60 ft 6 in / 18.44 m) and precise positioning in tight or obstructed areas.
Key Features
- Rapid elevation: Ground to 120 ft in just 95 seconds for faster cycle times.
- JibPLUS® articulating jib (8 ft / 2.44 m) with 125° horizontal and 130° vertical motion (+75°/-55°), plus 180° hydraulic platform rotator.
- Selectable capacity envelope: 1,000 lb (454 kg) restricted or 500 lb (227 kg) unrestricted.
- Full-time 4WD, oscillating axle (8 in / 0.2 m), 45% gradeability, and three selectable steering modes (including crab steer) for superior rough-terrain performance.
- Extendible axles (retracted width 8 ft 2 in / 2.49 m; extended 12 ft 6 in / 3.81 m) for enhanced stability.
- Fuel-efficient Tier 4 Final/Deutz diesel engine with low emissions.
- Proportional controls, 360° continuous swing, and multiple function operation.
- Standard platform: 36 x 96 in (0.91 x 2.44 m) with side entry, self-closing gate, AC receptacle, air line, and 5.5 kVA generator.
- Additional standard items: LED motion/amber beacon, ClearSky smart fleet connectivity hardware, tilt alarm, all-motion alarm, and 12V DC auxiliary power.
Benefits
- High capacity and reach reduce the need for multiple machines or repositioning, improving jobsite efficiency.
- Fast lift speed and precise controls boost productivity while minimizing downtime.
- Robust 100,000-psi steel construction delivers durability and stability in challenging conditions.
- Fuel efficiency and Tier 4 compliance lower operating costs and environmental impact.
- Excellent maneuverability (tight turning radius, drive-out axles) allows operation in confined spaces without sacrificing power.
- Enhanced safety features and fleet connectivity support better monitoring and compliance.
