Overview

The JLG 660SJ is a straight boom lift designed for efficient vertical and horizontal access with clear, direct outreach. This 2023 unit pairs low hours with the durability enhancements that contractors expect in real-world conditions: 4-wheel drive, oscillating axles, and foam filled tires that excel on challenging surfaces. The Deutz diesel powerplant is widely respected in the field for dependable starts and consistent torque, while SkyPower provides onboard power to the platform to run tools and attachments without extra generators or extension cords. A factory-installed jib enhances placement precision at height, and the 66' platform height gives crews the elevation needed for steel work, cladding, utilities, and general construction tasks. With JLG Factory Reconditioned pedigree and a 2015 core, this machine represents a smart balance of performance, longevity, and value.

Condition

As a JLG Factory Reconditioned machine with a 2015 core, this 660SJ benefits from a comprehensive overhaul completed by the OEM to restore structural, mechanical, hydraulic, and cosmetic components to a high standard. This professional reconditioning process helps extend service life, improve reliability, and reduce unplanned downtime compared to typical used units. With only 490 hours since reconditioning, it shows light utilization for its class. Beyond the JLG factory work, NLEQ has tested and inspected this boom lift to verify performance and function, so you receive accurate, honest, and reliable information on the unit’s current state. The result: a straight boom lift that’s ready to be put into service immediately.

Advantages

• Deutz diesel power: Renowned for durable design, maintainable components, and strong aftermarket support. In daily use, Deutz engines deliver consistent torque for smooth boom movements and confident travel over uneven terrain, helping crews stay productive.
• 4WD drivetrain: Four-wheel drive enhances traction on gravel, mud, packed soil, and other variable surfaces found on active jobsites. Operators gain better control and mobility, particularly when positioning for long, straight reaches.
• Oscillating axles: The oscillation allows the chassis to adapt to uneven ground, improving tire contact and stability while traversing ruts or dips. This feature helps keep work moving even when the site isn’t perfectly graded.
• Foam filled rough terrain tires: Foam filling adds puncture resistance and reduces the risk of flats that can bring a job to a halt. Combined with a rough terrain tread pattern, these tires are built for traction and uptime in demanding conditions.
• SkyPower onboard power: SkyPower supplies power at the platform so crews can run tools, welders, or lights without separate power sources. This reduces trip hazards and setup time, improving jobsite efficiency and helping finish tasks faster.
• Jib for precise positioning: The jib makes finishing moves at height easier, enabling fine adjustments without repositioning the chassis. That precision saves time during installation, inspection, and finishing work.
• 66' platform height: Provides the vertical access needed for a wide range of mid-rise construction and maintenance tasks. Crews can efficiently reach working elevations typical in structural steel, façade work, and MEP installations.
• JLG Factory Reconditioned assurance: OEM reconditioning adds a layer of confidence—components are evaluated and restored to a uniform standard that typical used machines may not match, supporting reliability and resale value.

Applications

The JLG 660SJ Straight Boom Lift is a versatile choice for contractors and facility teams who need straightforward reach with dependable performance. Its combination of diesel power, 4WD, oscillating axles, and foam filled rough terrain tires suits outdoor work where travel paths are imperfect and traction matters. Typical applications include:

• Structural steel erection, bar joists, and decking where a telescopic boom can approach targets directly.
• Exterior façade and cladding installation, including panels, EIFS, and curtain wall sections.
• Mechanical, electrical, and plumbing work at height, such as routing conduit or installing rooftop equipment.
• Industrial maintenance, plant turnarounds, and refinery work needing reliable rough-terrain access and onboard power via SkyPower.
• Utility, signage, and lighting installation where straight, stable outreach reduces repositioning.
• General construction, demolition support, and site infrastructure tasks requiring durable, low-maintenance tires and strong chassis articulation.

Ownership Value

This JLG 660SJ offers an attractive total cost of ownership. The Deutz diesel platform is known for long service life and an extensive service network, helping owners control maintenance and parts availability. Foam filled rough terrain tires reduce the frequency of flats and related downtime. Oscillating axles and 4WD reduce time lost to difficult travel paths by keeping the machine moving in adverse site conditions. SkyPower consolidates power needs, minimizing extra equipment and setup time. The JLG Factory Reconditioned pedigree with a 2015 core provides added confidence in structural integrity and component condition, which can translate to fewer surprises and a longer productive service window. Low hours (490) further support reduced near-term maintenance needs. Combined, these attributes create a compelling value proposition compared to buying new or rolling the dice on higher-hour, non-reconditioned alternatives.
