Condition and Operating Hours

With 1,823 hours of use, this JLG 400S Straight Boom Lift is in a practical working range for contractors and fleet operators seeking dependable equipment without the premium cost of low-hour machines. In aerial lift terms, this hour range indicates moderate utilization, meaning the machine has been actively used but still retains strong structural integrity and operational reliability. Every unit offered through NLEQ is carefully inspected, ensuring that hydraulic systems, boom functions, drive systems, and safety mechanisms are functioning as expected. Buyers can expect a machine that is job-ready, with performance suited for continuous use on active worksites.

Diesel Power for Demanding Job Sites

The diesel-powered configuration of this JLG 400S Straight Boom Lift provides the torque and endurance required for outdoor construction and industrial applications. Diesel engines are preferred in heavy equipment because they deliver consistent power under load, improved fuel efficiency for long operating cycles, and superior performance in rugged environments. This makes the machine especially suitable for extended shifts on construction sites, infrastructure projects, and maintenance operations where reliability and fuel economy directly impact productivity.

4WD Capability for Rough Terrain Performance

Equipped with a 4WD drive system, this Straight Boom Lift is built to handle uneven, muddy, gravel, or construction-grade surfaces with confidence. Four-wheel drive ensures maximum traction and stability when moving across challenging terrain, reducing slippage and improving operator control. This feature is particularly valuable for contractors working in outdoor environments such as industrial yards, pipeline projects, steel erection sites, and large-scale commercial construction where ground conditions are unpredictable.

40’ Class Straight Boom Reach

The JLG 400S belongs to the 40-foot class of straight boom lifts, providing excellent vertical and horizontal reach for mid-height applications. This range is ideal for electrical work, steel framing, exterior maintenance, signage installation, and general construction tasks requiring elevated access without scaffolding. The straight boom design ensures direct reach with minimal repositioning, improving efficiency and reducing setup time on the job site.

8-Foot Platform with Side Entry Design

This unit features an 8-foot platform with side entry access, offering a spacious and practical working area for operators and tools. The extended platform size allows multiple workers to operate simultaneously or provides extra room for materials and equipment needed at height. The side entry design improves safety and efficiency by allowing easy access in and out of the platform while maintaining secure positioning during elevated work. This configuration is especially beneficial for tasks requiring mobility and frequent tool handling.

Foam Filled Tires for Enhanced Durability

The foam filled tires on this JLG 400S Straight Boom Lift provide excellent resistance to punctures and flats, making them ideal for harsh job site conditions. Unlike air-filled tires, foam filled variants maintain consistent shape and performance even when exposed to sharp debris, nails, or rough surfaces. This significantly reduces downtime and maintenance costs while improving job site reliability. For contractors working in demolition zones, construction debris areas, or industrial environments, this tire setup is a major operational advantage.

Oscillating Axle for Superior Stability

The inclusion of an oscillating axle enhances the machine’s ability to maintain traction and stability on uneven terrain. This system allows the wheels to adjust independently to surface variations, keeping more tire contact with the ground at all times. As a result, operators experience smoother travel and improved safety when positioning the boom lift on rough or sloped surfaces. This feature is critical for maintaining balance during elevation and movement on challenging job sites.

Rough Terrain Tires for Job Site Versatility

Designed specifically for demanding outdoor conditions, the rough terrain tire configuration further strengthens this machine’s ability to operate in construction-heavy environments. Combined with 4WD and oscillating axle technology, these tires ensure consistent traction, better load distribution, and improved stability across dirt, gravel, and uneven surfaces. This makes the JLG 400S a dependable choice for contractors who cannot afford downtime due to ground limitations.

Applications and Industry Use

This Straight Boom Lift is widely used across multiple industries due to its versatility and performance capabilities. Common applications include construction site access, steel structure assembly, building maintenance, electrical installation, industrial inspection, signage installation, and facility repair work. Its ability to provide stable elevated access in rough environments makes it an essential asset for contractors, rental fleets, and industrial maintenance teams.

Ownership Value and Operational Efficiency

At a price of $28,900.00, this JLG 400S Straight Boom Lift delivers strong ownership value for buyers seeking a balance of performance and affordability. Diesel efficiency, durable construction, and low-maintenance foam filled tires contribute to reduced operating costs over time. The 4WD system and oscillating axle further enhance productivity by minimizing delays caused by terrain challenges. For businesses focused on maximizing uptime and return on investment, this machine offers a cost-effective solution with proven field performance.

Why This JLG 400S Stands Out

The JLG 400S is known in the industry for its reliability, ease of operation, and robust engineering. This specific unit enhances that reputation with practical features like diesel power, 4WD capability, foam filled tires, and a spacious 8-foot side entry platform. Together, these features create a machine that is not only powerful but also operator-friendly and highly adaptable to different job site conditions. Its 40’ class reach makes it a versatile solution for mid-height applications where stability and reach are equally important.
