Advantages

• 66' Platform Height and 72' Working Height: Efficiently access the work envelope commonly needed for mid-rise construction, steel and glazing, and industrial maintenance. Straight booms like the JLG 660SJ get you to height quickly and with fewer joystick inputs, which can improve cycle times and reduce operator fatigue.
• 4WD Drivetrain: Four-wheel drive provides essential traction on dirt, packed gravel, and uneven surfaces, helping crews move from set-up to set-up without bogging down. That means more time in the air and less time navigating the site.
• Rough Terrain Tires: Built for the jobsite, rough terrain tires help absorb irregularities and maintain stability on imperfect ground. This is especially valuable on work that spans early site prep through finish trades, where conditions change daily.
• Deutz Diesel Power: Deutz is known for durable, dependable diesel engines used widely in construction. In practical terms, that reputation translates to consistent torque, dependable starts, and broad parts availability—attributes that matter when uptime is your priority.
• SkyPower: SkyPower gives the operator onboard electrical power at the platform for running tools and accessories. Instead of dragging cords or relying on a separate generator, crews can plug in at height, improving productivity and simplifying jobsite logistics.
• Jib: The jib adds a critical degree of articulation, letting operators fine-tune their positioning around obstacles, facade details, or structural steel. This nuanced control can reduce repositioning, helping finish work go faster and cleaner.
• Straight Boom Simplicity: The 660SJ’s telescopic design is straightforward to operate and fast to extend to working height. For many tasks, that simplicity reduces learning curves and supports consistent performance across different operators.
• JLG Reconditioned 2021 (2008 Frame): Combining the robustness of a proven frame with a manufacturer recondition in 2021 offers a compelling balance of reliability and value. Buyers often find this route provides the look and feel they want with a lower cost basis than new.
• Low Hours: With only 559 hours, this unit reflects comparatively light duty for its class, helping extend the horizon before major wear items approach replacement intervals and supporting long-term fleet planning.

Applications
