This 1991 National 666A is a mounted boom truck — sometimes referred to as a crane truck — a type of work vehicle that combines a hydraulic crane boom mounted on a carrier chassis, used widely in construction, utilities, oil and gas, and general lifting and material-handling applications. National is a well-established name in the crane and lifting equipment industry, producing truck-mounted cranes that serve demanding commercial and industrial jobsites.
The carrier is a 1991 Western Star, powered by a Cummins engine and paired with an automatic transmission. The truck rides on a 20,000-lb front axle and 46,000-lb rear axles, giving it a robust foundation suited to heavy lifting work. The odometer shows 27,000 miles, and the boom has logged approximately 2,000 hours of use — relatively modest figures for a machine of this vintage that suggest measured working life.
The flatbed body is 18 feet long, constructed in steel, providing generous deck space for transporting materials, equipment, or rigging gear alongside crane operations. The boom is equipped with auxiliary hydraulics, expanding its utility for powering attachments or tools directly from the crane circuit.
The unit is located in New Hampshire, USA, and is offered in used condition.
