LONGER REACH
Manitowoc’s National Crane NBT50L Series features a 151-foot boom, first offsettable lattice jib
Longer boom length that increases jobsite versatility is the hallmark of Manitowoc’s National Crane NBT50L Series of boom trucks. It features four models (NBT50L, NBT55L, NTC50L and NTC55L) that are available with a 50-ton or 55-ton rating and can be configured to operate as a model NTC truck crane/boom-truck hybrid. The new series also has a 36-foot offsettable lattice jib, a first for National Crane.
The NBT50L Series offers a longer reach than the original NBT50 Series. The new models have a 151-foot boom and maximum tip height of 158 feet. With the added reach, there’s less need to swing a jib on the jobsite. This saves time for operators, enabling them to get more work done in a single day by increasing their efficiency.
Delivering flexibility
“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. “The added reach is only the beginning. These cranes offer three 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.”
All offer a working capacity of 10,000 pounds when the boom is fully extended at a 35-foot radius. When configured as an NTC, the crane has four distinct outrigger setups, including an exclusive 20-ton “truck crane” footprint for tighter jobsite requirements.
The NBT50L Series has a new superstructure design optimized to reduce deflection, offering higher lift capacities as well as greater operator confidence while lifting. Other new features include a 20-degree 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 available as options.
“With 151 feet of reach and additional jobsite options, this new National Crane model is out in front of the competition,” noted Vice President, Crane Division Rickey Bailey. “The impressive full-power reach, offsettable jib, multiple outrigger positions, removable counterweight system, tilting cab and ease of maintenance all make the new NBT50L Series very attractive.”
