The last picture from scooby is of a Brandt truck and a 120 c john deere(tracker) with a set of tie togs. The tracker on our gang uses a magnet. The tracker is designed to ride on the truck, only from the trailer to the tracks. The truck then sets on the tracks, backs up to the cars, the tracker is raised up on the platform and the tracker moves onto the car.The tracker moves back and forth by hydraulic motors. The long walking beam allows the machine to be positioned anywhere on the car. There are hydraulic clamps that clamp both the beam and carrige, 4 on each side. One set of clamps are always clamped to the car. Both ends of the beam or both on the carrige. Total weight of truck= 70,000 lbs, machine is 34,500 lbs.
Plus the weight of trailer. Need permits when we travel to a different place.
