Manitowoc has introduced an updated version of National Crane NBT50 Series of 45 and 50 tonne boom trucks, the NBT50L Series with a 46 metre boom plus an 11 metre offsettable lattice extension. 

There are four models in the range, the NBT50L, NBT55L, NTC50L and NTC55L. with 45.4 or 50 tonne rating and can be configured to operate as a model NTC, a truck crane/boom truck hybrid. When configured as an NTC, the crane has four outrigger width setups, including a six metre “truck crane” footprint for tighter job sites. All cranes in the series offer a capacity of 4,536 kg with the fully extended boom at a 10.7 metre radius.

The NBT50L also benefits from a new superstructure design, optimised to reduce deflection as well as higher lifting capacities. Other new features include a 20 degree hydraulic tilting cab, removable counterweight system, internal anti two block wiring, two camera system and a wireless wind speed sensor.

Boom truck product engineering manager Bob Ritter said: “With the NBT50L Series, we have delivered the boom length that our customers have been asking for. 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.
