Features

• Overload Protection – All National cranes are equipped with overload protection: – Load Moment Indicator (LMI) standard on all series 1400 machines. – LMI display and CPU are weatherproof. – LCD display is visible in full or low light. – All crane load lifting values are displayed simultaneously.

Self-lubricating “Easy glide” Boom Wear Pads – The self-lubricating boom pads, standard on the 1400, reduce the conditions that cause boom chatter and vibration. The net result is smoother crane operation.

 Internal Anti-two-block Wire – This exclusive design, standard on the Series 1400, routes the wiring through the inside of the boom. No more snagging the wire on obstructions.

•“H”-style Outriggers – Two sets of “H”-style outriggers with 24’ 6” (7.47 m) span, with removable ball and socket aluminum foot pads. Independent controls located on each side of the crane - can be positioned at mid-span setting of 17’ (5.18 m).

Continuous Rotation/Glide Swing – The series 1400 is supplied with continuous rotation standard, along with the “glide swing” feature - allowing free swing during rotation - and a manually applied foot brake. 375° non-continuous rotation is also available.

Adjustable Swing Speed – Standard on the 1400. A control knob located on the swing motor brake release valve can be easily adjusted to the crane operator’s swing speed preference.

Oil Cooler – Radiator mounted at boom rest with electric fan is standard, with an option for a heavy-duty cooler for high duty-cycle applications.

Heavier Duty Torsion Box – The stronger standard torsion box improves rigidity, reduces truck frame flex and reduces the need for counterweight.

Speedy-reeve Boom Tip and Sheave Blocks – These standard features simplify rigging changes by decreasing the time needed to change line reeving.

Pre-painted Components – Painting crane components before assembly reduces the possibility of rust, improves serviceability and enhances the appearance of the machine.

Deluxe Operator’s Cab – Rigid galvannealed steel structure, well insulated, with ample safety glass for operator visibility and comfort. Multi-position seat with arm rest controls, ventilation fans, diesel heater, wipers. Optional air-conditioning is available. Optional open-seat control station in lieu of enclosed cab is available.

Improved Serviceability –

– Bearings on the boom extend and retract cables can be greased through access holes in the boom side plates.

– Number of internal boom parts has been reduced, decreasing service time when rebuilding the machine.

New State-of-the-art Control Valve – Provides smoother operation. The new design eliminates parts, reducing repair costs and improving the machine’s serviceability.
