New National Crane 400B Boom Truck for Sale
The 400B provides a 10-ton capacity at a five-foot radius. Three basic boom lengths and two optional jib combinations complete this versatile perfomer. Five mounting configurations, including rear mount, are available.
Models
Main boom: With multiple boom length options including the class leading 17,07m (56 ft) boom length, the 400B has the strength and capacity you need to tackle the toughest jobs, while in a compact crane.
Multiple Mounting Configurations: The 400B offers tremendous flexibility in mounting configurations to tailor to specific applications. Standard mount (crane frame located behind truck cab), Rear Mount (crane frame located at the rear of the truck frame), and Tractor Mount (crane frame located at the center of a short wheelbase truck frame equipped with a fifth wheel) are all available. This allows optimization of the crane to better suit the needs of the job - whether hauling construction materials on the flatbed, delivering and placing pre-cast concrete components, or hauling a flatbed trailer.
Dual side control station: Traditional mechanical control levers and layout with an operator station located on both sides of the crane. Smooth operating hydraulic control system allows for optimum multi-functioning for all crane functions as well as outrigger control. Automotive switches and wiring allows for reliable performance and control. Electronic engine start/stop switches with foot pedal throttle control at each side. The integrated Hydraulic Capacity Alert (HCA) system provides real-time feedback to the operator about capacity, and anti-two-block (ATB) status via gauges and indicator lights located at each control station.
Outriggers: Multiple outrigger configurations available for each mounting configurations to best handle the job at hand. From standard “A-frame” style outriggers, to over-frame mounted “out and down” style, flexibility is designed in. Outriggers are equipped with fixed floats and a level indicator (sight bubble) is located at the operator stations.
