Foam Filled Tires add puncture resistance and minimize downtime from flats. Outriggers deliver an extra layer of leveling and stability when work surfaces demand it. The Single Deck - Manual Extension Deck lets operators push out for additional horizontal reach, which reduces repositioning, saves time, and improves productivity. At 43' platform height and 49' working height, crews can tackle a broad variety of exterior and interior scopes safely and efficiently. ANSI compliance underscores a focus on recognized safety standards.

Condition

This 2020 Genie GS4390RT shows just 262 hours of use, reflecting light duty and careful operation. As with every machine offered by NLEQ, it has been carefully tested and inspected prior to sale so that buyers receive accurate, honest, and reliable information. Functional checks cover lift functions, drive and steering, 4WD engagement, Dual Fuel operation, extension deck actuation, outrigger deployment and leveling, and safety systems in line with ANSI configuration. Foam Filled Tires are evaluated for integrity, and the scissor stack, platform, and gate components are reviewed for structural soundness and smooth operation. Controls, switches, and emergency functions are verified for responsive performance, helping ensure this unit arrives ready for immediate work. Buyers can expect a clean, work-ready rough terrain scissor lift aligned with professional fleet standards.

Advantages

• Dual Fuel versatility: Switch between gasoline and LP depending on site rules, indoor/outdoor use, and fuel availability. This flexibility can reduce refueling delays and keeps the lift productive across different environments.
• 4WD traction: Four-wheel drive improves performance on gravel, packed dirt, and uneven terrain common to construction sites, cutting down on repositioning delays and helping maintain schedule.
• Foam Filled Tires: Enhanced puncture resistance reduces downtime from flats and provides consistent support on debris-laden ground, contributing to safer, steadier operation.
• Single Deck - Manual Extension Deck: Gain extra horizontal reach without moving the entire machine. Ideal for finishing work, façade access, or reaching over parapets and obstacles along building lines.
• Outriggers for stability: Level and stabilize the lift on challenging surfaces. Outriggers add confidence when work areas aren’t perfectly flat, helping operators maintain a solid working platform.
• Rough terrain design: Purpose-built for tough sites with features that improve mobility and uptime, allowing crews to stay productive as ground conditions change.
• 43' platform height / 49' working height: Reach common mid-rise exterior zones and many interior high-bay areas. This height range covers a wide span of installation and maintenance tasks.
• ANSI compliant: Built and configured to recognized standards to support safety-minded operation and facilitate acceptance on professional jobsites.

Applications

The Genie GS4390RT rough terrain scissor lift is a go-to choice across construction, industrial maintenance, and facility management. Its working envelope and robust chassis make it suitable for exterior building work, high-bay interiors, and sites with unimproved ground. Crews benefit from a spacious, stable platform that can support multiple technicians and materials, improving workflow efficiency while reducing up-and-down cycles.

• Commercial construction: Curtain wall prep, exterior siding, EIFS, glazing assistance, and architectural finishes at heights up to 49' working height.
• MEP trades: Installing and servicing ductwork, conduit, sprinkler systems, lighting, and overhead utilities in warehouses, manufacturing plants, and distribution centers.
• Industrial facilities: Routine maintenance, equipment access, and repair tasks where rugged jobsite mobility is essential.
• Concrete and steel work support: Edge work, embeds, layout, and punch-list tasks where horizontal reach from the manual extension deck reduces repositioning.
• Property management: Exterior maintenance, signage, façade repairs, and seasonal tasks on campuses, malls, and large commercial properties.
• Event and infrastructure: Stadiums, arenas, airports, and public works projects requiring stable elevated access over wide floor areas.

Because it is Dual Fuel, this GS4390RT can adapt to a variety of indoor and outdoor environments. The ability to run on LP where emissions policies require it increases jobsite acceptance, while gasoline operation ensures straightforward fueling when LP is not available.

Ownership Value

Genie’s reputation for durability and parts availability supports strong lifecycle value. A 2020 unit with only 262 hours puts you well ahead in terms of useful life, maintenance confidence, and resale potential. Foam Filled Tires and 4WD help protect productivity on tough sites, while Outriggers expand the range of feasible work surfaces without compromising safety. The Single Deck - Manual Extension Deck minimizes repositioning, which saves time and reduces wear on the drive system over the course of a project.

From a fleet management standpoint, Dual Fuel flexibility can streamline dispatching across different job types. One machine can handle indoor tasks under LP and immediately transition outdoors on gasoline, reducing the need for multiple specialized units. ANSI compliance and the well-known Genie GS4390RT platform also make operator onboarding more straightforward, as many technicians are already familiar with this model’s layout and controls.
