400S & 450AJ Boom Lifts: Designed for Longer Life and Lower TCO

400S & 450AJ Boom Lifts: Designed for Longer Life and Lower TCO

JLG Industries, Inc.

We took a closer look at what matters most to rental customers: energy efficiency, serviceability and durability. The result? Redesigned boom lifts with time- and money-saving features.

Frequent service calls, rising fuel costs and replacing worn or broken parts—these operating costs add up. We routinely hear from rental customers about the cost of maintaining their assets—especially highly utilized products like the 400S telescoping boom lift and 450AJ articulating boom lift.

400S and 450AJ upgrades

After having some in-depth interviews and discussions with our rental customers, we used their feedback to help redesign our 400S and 450AJ boom lifts. New and expanded features in these boom lifts, like a redesigned hydraulic system, top-of-the-line components and improved overall serviceability, help reduce maintenance costs for owners and fuel costs for end users.

Greater capacity for greater efficiency

Unrestricted platform capacity increased to 600 lb on the 400S and 550 lb on the 450AJ, while the restricted platform capacity on the 400S can accommodate up to 1,000 lb. This expanded platform capacity allows operators to carry more materials, reducing the number of up and down cycles and contributing to improved efficiency for the end user. It also leads to less wear and reduced cost of ownership.

High-quality parts make a difference

400S and 450AJ owners make fewer service calls for valve and hose leaks thanks to a newer, streamlined hose routing system with fewer hydraulic hoses. The machines also now feature Zero-Leak Gold® plugs, which have proven to significantly reduce leaks in valve blocks over other plugs. Both boom lifts have an improved cast axle and a spindle design with tapered kingpins to strengthen the joint between the spindle and axle. This doubles the life of this high-stress area. DuraTough hoods offer more heat and impact resistance than previous hood materials, while still having a modern, streamlined appearance.

Faster troubleshooting

An onboard multifunction digital indicator (MDI) gauge and interactive ground display provide important information, like hours on the machine, battery charge, fuel level and diagnostic fault codes. Not available on previous models, these additions to both machines feature energy-efficient LED lights, provide operators and technicians with both an English text display and fault codes and reduce the need for a handheld analyzer. This saves valuable time troubleshooting and diagnosing an issue with a machine. In some cases, it even eliminates the need for a service call, equipping on-site technicians to identify and solve a problem without waiting for a service technician to arrive.

Fewer RPMs mean less wear on the engine and more fuel savings

Rental owners will appreciate the savings that come from an improved hydraulic system and a new, fully variable, on-demand engine RPM. This addition to the 400S and 450AJ results in more efficient engine operation with significantly fewer RPMs—up to 30 million fewer engine revolutions over the life of the machine. This means less wear on bearings, pistons, rings and pumps, plus increased fuel efficiency and an estimated $500 annual savings on fuel for the end user.

By bolstering the durability and serviceability of the 400S and 450AJ, these machines now have a longer lifecycle. And rental owners appreciate the increased savings that come from better fuel efficiency and reliability.
