This 2014 National 400B is a mounted boom truck — sometimes referred to as a crane truck — designed to lift and position heavy loads at height and reach, making it a core piece of equipment in utility construction, telecommunications, pipeline work, and rail maintenance operations. National is a well-established American manufacturer of boom trucks and hydraulic cranes, building equipment trusted across the construction, energy, and infrastructure industries.
The crane specification centres on a 20,000-pound lift capacity paired with a 37-foot boom, giving the unit meaningful reach and lifting power for a wide range of field applications. What sets this particular machine apart is its DMF rail gear fitment, which classifies it as a HiRail crane truck — meaning it can travel and operate directly on railway track as well as standard road surfaces, a specialised capability that significantly expands its utility for railroad maintenance and infrastructure crews.
The carrier truck is powered by a Detroit DD13 engine, a heavy-duty inline-six diesel unit widely used in vocational and work truck applications for its durability and torque output. Drive is handled through an Eaton 8LL transmission, a twin-countershaft gearbox with eight speeds that is a proven choice for severe-duty truck service. The drivetrain is completed by a 3.90 rear axle ratio. The truck rides on air ride suspension, which helps protect both the chassis and the crane components over varied road and rail surfaces.
The odometer shows 162,514 miles, and the seller describes the overall condition as very nice. This unit is located in Alabama, USA, and is offered at $78,000.
