National Crane Displaying NBT45-2 Boom Truck This Week at Work Truck Week 2022 in Indianapolis

An ultra-nimble, short-chassis version of a National Crane NBT45-2 boom truck will be on display at Work Truck Week 2022 in Indianapolis this month, demonstrating how both Manitowoc and its customers can benefit from the feedback gathered as part of its ongoing Voice of the Customer (VOC) program.

The new short-configuration National Crane NBT45-2 can be seen at the Peterbilt booth (Level 1 — Exhibit Hall & Meeting Rooms — Booth 1801) during Work Truck Week, taking place March 8-11, 2022, at the Indiana Convention Center.

The boom truck that will be on display highlights the role that Manitowoc’s Truck Mod Center and Lift Solutions departments play in developing customized solutions to meet the industry’s evolving needs. This short-chassis model is one example of the infinite configurations that can be engineered to ensure that a customer’s truck and crane are the perfect match and are field-ready when they leave the factory.

Based around a 2023 Peterbilt 567 chassis, the short-configuration NBT45127-2 boasts class-leading flexibility in confined spaces and congested jobsites as a result of shortening the wheelbase by around 23 in, so it now measures only 250 in.

“Our customers were telling us they needed a 40 USt – 45 USt capacity crane, but on a more compact chassis than standard,” said Bob Ritter, National Crane product manager. “Our application engineers put a lot of effort into fine-tuning the chassis until they delivered a boom truck with a chassis with the tightest turning radius in its class.”

This impressive feat was made possible by relocating the hydraulic tank from the frame rail to the deck, freeing up space between the back of the truck cab and the crane torsion box. With the full machine length now under 38 ft, its flexibility in both urban and suburban settings has been greatly enhanced.

Another notable advantage of the new chassis configuration is the use of a 13,500 lbs pusher axle, rather than a tag axle, alongside the existing 46,000 lbs rear tandem arrangement. By helping operators better navigate inclines and narrow driveways, this improves the speed with which they can complete projects.

“The shorter chassis also makes it easier for the operator to ready the crane for transport by tying off the block without extending the boom,” Ritter said. “They can now stow the boom and hook the block to the front of the truck more efficiently, so they can get to the next jobsite faster.”

Once reaching the next jobsite, the simplified setup allows outriggers to be quickly set and hook blocks to be unstowed using front bumper-mounted controls, removing the need to climb in and out of truck and crane cabs. Optional wireless remote controls make this process more efficient, while the NTC Performance Package adds more versatility during setup.

With a GVW of 79,500 lbs, propelled by a 500 HP Cummins X15 engine and Allison 4500 RDS Transmission, the new crane also benefits from the optional 6,000 lbs counterweight package. It features a 127 ft five-section full-power main boom, plus a 31 ft – 55 ft telescopic jib that produces a maximum tip height of 189 ft.

Operator neck strain can be averted thanks to a hydraulic tilting cab that offers inclinations up to 20°. Other ergonomic perks include a heated seat and high-output HVAC system to ensure comfort and productivity in all weather conditions, while the speed of the single- and dual-axis electronic joystick controls can be easily adjusted to suit operator preference.

As well as simplifying setup and operation, the color, graphical RCL with integrated control system also enables monitoring of all vital truck and crane data from within the crane cab, such as hydraulic system pressure and temperature. The need for troubleshooting with a laptop is further minimized through state-of-the-art onboard diagnostics and real-time error code reporting.
