Crane designed to provide smooth operation

The new, 45-ton capacity, NBT 45 features a 142-foot, five-section boom, which is the longest in its size range. When equipped with a 55-foot boom extension, the combination will provide a lifting tip height of 204 feet and a basket working height of over 210 feet.
“The long boom allows the operator to perform more lifts without using the jib,” said Brian Peretin, vice president of sales and marketing for National Crane. “This means reduced setup time and ultimately improved efficiency.”
Shorter boom lengths – 103 feet and 127 feet – are also available for this crane. All of the boom sections are supported by one hydraulic extend cylinder, which minimizes maintenance.
A number of features on this crane are designed to provide smooth crane operation. Easy Glide boom wear pads reduce the conditions that cause boom chatter and vibration. And a new state of the art control valve provides smoother operation. This new valve design also eliminates parts, reducing repair costs and improving serviceability.
All National Crane boom trucks are equipped with overload protection. A load moment indicator is standard on all cranes in this series. The LCD display is visible in full or low light and displays all crane load lifting values simultaneously.
The NBT 45 is one of three cranes in National’s new NBT 40 Series. The other cranes in the series are the 36 USt NBT 36 and the 40 USt NBT 40.
National Crane units can be mounted on many different carrier types. This is particularly helpful in controlling spare parts and maintenance costs if a company already has boom trucks mounted on certain trucks in its fleet.
