National Crane NBT45-103 Specifications

No longer in production, the 45-ton National NBT45-103 is part of the NBT45-1 boom truck crane product line and comes with a stronger standard torsion box that improves rigidity, minimizes truck frame flex, and reduces the need for a counterweight.  The main telescopic boom section is 31'-103' (115' tip); comes with an optional 31' -55' two-piece jib extension for a maximum tip height of 166'.

Features:

• Easy Glide boom wear pads reduce the conditions that cause boom chatter and vibration. The net result is smoother crane operation
• Speedy-reeve boom tip and sheave blocks simplify rigging changes by decreasing the time needed to change line reeving
• Painting crane components before assembly reduces the possibility of rust, improves serviceability, and enhances the appearance of the machine
•  State of the art control valve provides smoother operation. The new design eliminates parts, reducing repair costs and improving the serviceability of the machine
• Bearings on the boom and retract cables can be greased through access holes in the boom side plates
• Boom sections are supported by one hydraulic extend cylinder, minimizing maintenance
• Two- grooved drum hoist with cable packer, electronic drum rotation indicator
