Advantages

Choosing a 2017 JLG 400S straight boom lift brings several clear advantages to owners and operators who need dependable up‑and‑over access and straightforward operation:

• Reliable reach and positioning: A straight boom lift is built for fast, direct elevation and horizontal reach, reducing time spent repositioning compared with some other lift types. This means quicker task setup and more productive hours on the clock.
• Diesel power: Diesel provides strong, consistent torque for drive and lift functions, a plus on rougher ground and active construction sites. It’s easy to refuel, widely supported, and well‑suited to extended operation intervals.
• 4WD traction: Four‑wheel drive helps you move across uneven or loose surfaces with more control. On active jobsites where soil, gravel, or wet grass can challenge a machine, 4WD reduces the risk of getting stuck and keeps crews productive.
• Straightforward serviceability: JLG’s 400S platform is known for practical maintenance access and excellent parts support. Straight boom lifts typically feature simplified systems compared with more complex articulating platforms, which can help keep service and downtime manageable.
• Operator familiarity: The JLG 400S is a widely used model. Many operators understand its controls and behavior, shortening the learning curve and supporting safer, more efficient work.
• 40‑ft class efficiency: Being in the Platform Height 40(ft.) class means you get a versatile working envelope that fits a wide range of tasks without the higher transport and setup considerations of larger machines.

If your application prioritizes ground engagement and stability, many buyers in this category also evaluate options such as Rough Terrain Tires or an Oscillating Axle for additional jobsite capability. If those features are important to your work, ask our team about configuration details on this specific unit so you can match the boom lift precisely to your site conditions.

Applications

The 2017 JLG 400S straight boom lift is a practical choice for contractors, facility teams, and rental fleets seeking dependable reach in a mid‑range footprint. Common use cases include:

• Structural and steel erection support: Positioning crews for bolting, welding support, and bracing tasks where direct, stable reach is essential.
• Exterior envelope work: Cladding, siding, EIFS, curtain wall, glazing preparation, and sealant application that benefit from fast boom repositioning along long facades.
• Commercial construction and fit‑out: Elevating teams for overhead work, staging signage, and installing MEP components on exteriors.
• Industrial maintenance: Accessing high bays, process lines, and exterior equipment where a straight boom lift provides quick point‑to‑point movement.
• Infrastructure and utilities: Bridge, overpass, lighting, and traffic infrastructure maintenance where 4WD helps traverse shoulders and work zones.
• Facilities and property management: Routine exterior inspections, painting, and repairs in large commercial complexes.

Because the JLG 400S pairs diesel power with 4WD, it’s particularly useful on job sites with varying terrain or seasonal conditions. When time and access are critical, the ability to drive and position confidently can make a material difference in job throughput and labor efficiency.

Ownership Value

Adding this used JLG 400S to your fleet is a sound business decision for several reasons:

• Lower cost of acquisition: At $28,900, this unit offers a fraction of the cost of a new lift, freeing capital for other equipment needs while still delivering the capability your projects require.
• Late‑model dependability: The 2017 model year provides a balance of modern design and field‑proven reliability. You benefit from mature parts availability and service procedures that keep maintenance predictable.
• Diesel + 4WD versatility: The diesel engine and 4WD drivetrain help expand the environments where you can confidently operate, reducing the need for task‑specific rentals and improving asset utilization.
• Residual value: JLG straight boom lifts are respected in the used market, which can support stronger resale value down the line when it’s time to rotate equipment.
• Operator efficiency: Familiar controls and the direct reach of a straight boom lift mean less time training and more time producing, improving ROI from day one.
