Boom Truck Series Offers Two-in-One Versatility

The NBT40-1 Series of boom trucks from National Crane is available with an aerial lift configuration, functioning as a hybrid between a crane and a vehicle-mounted aerial lift. The resulting adaptability can eliminate the need for two single-purpose machines, according to manufacturer Manitowoc.

Three Models with Different Lift Capacities

The series comprises three crane models, each with different boom lengths and maximum lifting capacities. The three models — the NBT36-1, NBT40-1, and NBT45-1 — are fully compliant with Occupational Safety and Health Administration (OSHA) requirements and aerial lift and mobile crane industry standards.

“The dual-rated NBT40-1 Series offers the best of both worlds with straightforward setup, clear steps to reconfigure as an aerial lift, and simpler, smarter operation when in use,” explained Justin Pilgrim, global product director for boom trucks and carrydeck cranes at Manitowoc.

The boom trucks deliver a number of operator advantages.

“These include increased operator awareness, thanks to a radio remote control console that provides real-time status and function slowdowns when reaching the maximum working envelope; an operator presence footswitch; and an auxiliary lowering system — to name just a few,” Pilgrim explained.

Aerial Lift Reconfiguration Simplified

Each model in the series is a full-capacity crane and can be reconfigured as an aerial lift without hauling test weights or conducting trial lifts or proof load tests before use.

The 161-foot boom length offers platform working heights of 169 feet on the main boom and 206 feet on the jib. This is well-suited for the most demanding aerial lift applications while also delivering solid crane performance, according to Manitowoc.

The 142-foot boom provides the most well-rounded performance, featuring strong lifting capacities and an aerial lift platform floor height of 150 feet with the main boom and 205 feet with the jib extended.

Utility-focused options include a hydraulic tool circuit in the aerial lift platform, a pressure intensification manifold to permit tool use of up to 10,000-lbs. per square inch in the platform, and wind speed indication at both operator control stations.

In addition to public utility applications, the trucks can be used for such jobs as tree trimming and signage work.
