Freight Seesaw is an axle weight calculator that uses various parameters including pallet pattern to predict gross drive and tandem axle weights for any truckload on same-sized pallets. Any unit of measure (inches, centimeters, etc.) can be used. (1) “King-to-Mid” and (2) “King-to-Rear” are the rearward distances from the kingpin to (1) the midpoint of the two drive axles and (2) the center of the rear tandem axle.
(3) Tandem Sep is the distance between the tandem axles.
