Advantages

• Deutz Diesel Power: Known across the industry for durability and fuel efficiency, the Deutz diesel engine provides the steady torque and reliability you want in a high-duty-cycle straight boom lift. A proven powerplant helps reduce surprises, simplifies maintenance planning, and supports long-term uptime.
• 4WD Traction: True four-wheel drive helps the JLG 660SJ maintain traction on uneven, muddy, or loose ground, advancing confidently over ruts and soft soils often found on commercial building sites, infrastructure projects, and industrial yards.
• Foam Filled Rough Terrain Tires: Foam filled tires are designed for severe jobsite conditions. They reduce the risk of downtime from flats and offer a stable ride over debris, gravel, and rough terrain. The rough terrain tread enhances grip and helps maintain control on challenging surfaces.
• SkyPower On-Board Power: SkyPower gives you integrated power on the platform, enabling operation of electric tools, welders, and lights without the hassle of trailing cords from external generators. This saves setup time, reduces clutter, and streamlines higher-efficiency work at height.
• Factory Jib: The jib adds an extra articulation point, enabling finer positioning and improved access to tight or obstructed work areas. It helps operators align with precision when working around steel, piping, façade elements, or structural members—enhancing both productivity and safety.
• Straight Boom Efficiency: The straight boom configuration is prized for fast elevation, predictable outreach, and straightforward controls. Crews can get to the work quickly and maintain steady platform stability, which supports consistent productivity over long shifts.
• 2025 JLG Factory Recon with Warranty: A late-model, factory-reconditioned unit with a 3 Year/3000 hr Factory Warranty significantly reduces risk. You gain the financial confidence of warranty backing plus the performance of a machine that’s been reviewed and prepared to manufacturer standards.

Applications

The JLG 660SJ Straight Boom Lift with diesel power, 4WD, foam filled rough terrain tires, SkyPower, and a jib is an all-around performer for elevated tasks across:

• Utilities and Infrastructure: Bridge maintenance, substation work, lighting and signage installation, and overpasses where straight boom reach and jib articulation provide clearance and positioning.
• Warehouse Exteriors and Distribution Hubs: Canopy repairs, roofline work, and façade maintenance with simplified logistics thanks to on-board power and reliable diesel operation.
