A tip-up trailer includes an ICC bumper that has been structurally enhanced to support the entire load of a loaded shipping container jointly with the rearward-most axle of the trailer. The bumper includes a rotatable bearing on a lower member, which permits the lower member to travel along the ground as the tipped-up trailer is lowered after loading. The method of the invention includes the initial step of connecting a container to a tip-up trailer with the doors of the container oriented towards the forward end of the trailer. The doors are opened and the forward end of the trailer is raised. The container is then loaded with bulk material. Once the container doors are closed, the forward end of the trailer is lowered while bearings on the bumper roll on the ground.
