Manitowoc extends reach of boom truck cranes

Manitowoc has introduced a long-reaching boom truck series of cranes. The reach of the four NBT50L models has been increased compared with the outgoing versions and they are the first in the company’s National Crane range of machines to feature an off-settable lattice jab.

The NBT50L series offers a 151ft (46m) boom and a maximum tip height of 158ft (48m). With the added reach, there’s less of a need to swing a jib on the jobsite. This saves time for the end user, enabling them to get more work done in a single day by increasing their efficiency. The new boom truck series also features an 36ft (11m) offsettable lattice jib, a first for National Crane.

To maximize flexibility for operators, the cranes are being offered with multiple configurations. Each machine can be set up with a 50 ton or 55 ton rating; and can be adapted to operate as a truck crane or boom truck.

“With the NBT50L series, we’ve delivered the boom length that our customers have been asking for,” said Bob Ritter, product engineering manager for boom trucks at Manitowoc.

“And added reach is only the beginning. These cranes also offer three different lifting configurations, improved stability, higher capacity-at-reach and easier serviceability, all with the goal of enabling companies to win and complete more projects with a single crane than ever before.”

The NBT50L series benefits from a new superstructure design that has been optimized to reduce deflection, offering not only higher lifting capacities, but greater operator confidence while lifting.

Other new features include a 20° hydraulic tilting cab, removable counterweight system and internal anti-two-block wiring. A two-camera system for operator visibility and a wireless wind-speed sensor for lift planning are also available as options.
