Advantages and What They Mean on the Job

• Diesel: The diesel configuration provides strong torque and reliable engine performance for demanding jobsites. It handles grade, soft ground, and accessory loads with stable power delivery, helping crews maintain pace during long shifts without sacrificing responsiveness.
• 4WD: Four-wheel drive translates to confident mobility over uneven, wet, or soft terrain. It improves approach and departure capability and helps you reposition the boom safely and efficiently across the site with less risk of getting stuck.
• 8' w/Side Entry Platform: The wider, 8-foot platform offers additional working room for personnel, tools, and materials. The side entry design streamlines access, especially when carrying materials or working in tighter spaces, and can reduce time lost climbing over rails.
• Foam Filled Rough Terrain Tires: Foam-filled tires significantly reduce downtime from flats and slow leaks while supporting steady travel over debris-strewn surfaces. As Rough Terrain Tires, they are designed to maximize ground contact and stability on jobsite surfaces, contributing to a surer, more comfortable ride and platform steadiness.
• Oscillating Axle: An oscillating axle helps all four tires maintain ground contact as the machine traverses uneven ground, enhancing traction and stability. The result is smoother travel and more confident positioning before elevating the boom.
• SkyPower: SkyPower brings integrated power to the platform so operators can run compatible tools and accessories without hauling separate generators. This minimizes setup complexity, reduces cords on the ground, and helps teams move from task to task more efficiently.
• Platform Height 40(ft.): A platform height of 40 feet provides an effective reach for mid-rise construction, steel erection, facility maintenance, signage, and more. The Straight Boom Lift design gets you to working height quickly with direct, telescopic reach that’s easy to control and position.

Applications

The JLG 400S Straight Boom Lift serves a wide range of trade work where reliable 40 ft reach, outdoor mobility, and precise platform placement matter. Typical uses include:

• General construction and framing where you need clean, straight outreach to set components at height
• Steel erection, mezzanines, and structural installs requiring stable access and careful placement
• Exterior cladding, EIFS, siding, and window installation on mid-rise projects
• Building maintenance, painting, and façade repairs with repeated up/down cycles
• Electrical, signage, and lighting installation where platform power via SkyPower is an advantage
• Industrial plants and refineries requiring rugged mobility, 4WD, and foam-filled tire reliability
• Infrastructure and utilities work with mixed terrain approaches and uneven surfaces
• Rental fleets looking for a proven, in-demand 40 ft boom with straightforward operation and strong residual value

Ownership Value

Purchasing a used JLG 400S is a strategic choice for buyers seeking proven dependability, simplified maintenance, and excellent parts availability. JLG’s support network and common components help control total cost of ownership. Features like Diesel power, 4WD, and foam-filled tires reduce interruptions that slow crews down. The 8' w/Side Entry Platform supports safer, faster access and makes multi-person tasks more comfortable, while the oscillating axle helps protect traction and productivity on irregular surfaces. SkyPower capability further boosts value by enabling on-platform power for compatible tools, often removing the need to mobilize separate power sources and saving both time and transport effort.

Because Straight Boom Lifts like the 400S are easy to train on and familiar to most experienced operators, onboarding time is minimized. For buyers scaling fleets, the JLG 400S is known for strong utilization in the 40 ft class—an asset size that fits a broad range of everyday work scopes without the footprint and transport demands of larger machines.
