This is the truck I'm looking at:
2006 PM 80027+J1204 Knuckle Boom 80 ton/m - 110' vertical reach - on 2006 International Paystar Ta-Ta & 22' Deck | Boom Trucks : Concrete Pump Trucks : Knuckle Booms : Knuckle Boom Cranes : Crane Truck : BIK Hydraulics Ltd.
It has a 304" wheelbase according to the crane dealer, but I think they measured from the center of the front steer axle to the center of the dead area between the drive axles and I think they should of measured from the center of the dead area between the steer axles to the center of the dead area of the drive axles.
