National Crane to showcase equipment with multi-industry capabilities at CONEXPO-CON/AGG 2020
New series of boom trucks feature improved load charts and extended boom lengths, among other features
National Crane will showcase two of its newest models at CONEXPO-CON/AGG 2020: the newly unveiled NBT40-2 series boom trucks and the NBT60L that was released in late 2019. Both the NBT40-2 series and the NBT60L are marked by their ability to work across several industries.
The NBT40-2 series is one of six new cranes that will make tradeshow debuts from Manitowoc at this year's show. The NBT40-2 series is a combined re-engineering of the NBT40-1 series and popular NBT50L series, by upgrading the product in terms of capacity, reach, comfort and advanced features while maintaining the same overall weight as the NBT40-1.
The new NBT40-2 series has the option for either a 40 USt or 45 USt (36.3 t or 40.8 t) capacity, and a 127 ft (38.7 m) or 142 ft (43.3 m) main boom. It will offer a two-piece 31 ft (9.4 m) - 55 ft (16.8 m) telescoping jib and it features a maximum tip height of 150 ft (45.7 m), which can extend to 204 ft (62.2 m) with the jib.
The turntable and torsion box have been redesigned for a solid feel, even when lifting out at the extents of the load chart, and the boom has been re-engineered for increased boom stiffness to maximize load chart and minimize flex. A redesigned, fixed counterweight system has enabled National Crane to optimize the capacity of the boom truck, ensuring it has best-in-class load charts while remaining weight neutral compared to its predecessor.
These specifications make this crane ideal for work in the commercial or residential construction industries, due to its versatile boom lengths and close charts or capacity at reach. It's also ideal for the utility or tree service industries, especially when needing 200 ft (61 m) plus of platform height. The tree service industry in particular will find the crane suitable for its rugged design with high capacity and long reach.
The NBT40-2 boom truck series comes standard with a hydraulically tilting cab and a heated operator seat. Also standard is a front-bumper-mounted SFO and hoist control. The series has the option for wireless outrigger controls, as well as four position outriggers that enable quicker and easier setup for increased efficiency. It has an easy to use color graphical display and real-time diagnostics for simplified troubleshooting without the need for a laptop. Additional features include electric hydraulic controls with speed adjustability, an optional multiple camera system for increased job site visibility and a fully integrated wireless wind speed indicator.
The NBT40-2 series shares several traits with the NBT50L series, including its electrical and controls architecture. The commonality between these two models will minimize operator and technician training for users of both products, as well as provide easier maintenance and parts access compared to its predecessor.
National Crane will showcase another recently released boom truck at CONEXPO, the NBT60L, which made its debut in September 2019. This 60 USt (54.4 t) crane features the longest boom length in its tonnage class with 151 ft (46 m) of main boom and a maximum main boom height of 161 ft (49.1 m). The boom length is 15 percent longer than the closest competitor model in the class.
As one of the latest models in the R2-Series excavator lineup, the Bobcat® E88 delivers durability, performance and quality for more productivity. Technically speaking, it's a compact machine, but it brings big performance with its redesigned engine and optimized lift performance, plus undercarriage and counterweight improvements. All these enhancements make this excavator one of the highest-performing models in its size class. With impressive over-the-side lift capacity, you can dig with greater confidence over the side of the machine. Put it to the test against similar models from other manufacturers. You'll see that the E88 can outwork the competition.
