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
