  • Patent number: 4068813
    Abstract: A tie-down method and apparatus are disclosed which facilitate automated, resilient securing of wheeled vehicles to shipping pallets or the floors of containers. Four links are detachably pivoted to the vehicle frame. Rollers at the lower ends of the links engage rails on the pallet or floor as the vehicle is moved into place by cooperating support equipment. The forward rollers engage spring loaded stops carried by the rails. The aft rollers are forced along the rails toward the forward rollers and the angling of the links compresses the vehicle springs and tires and the spring loaded stops. Lock-stops are set in place behind the rear rollers to secure the vertically and longitudinally resilient tie-down.
