Abstract: A highway trailer carrier has a support base, front and back lift braces attached to the support base, and at least one trailer support attached to the support base for supporting part of the trailer. The support is attachable to the trailer and collapsible so that it does not interfere during loading and unloading. The support base further has wheel wells and anchors for securing the trailer to the support base. Both the support base and the lift braces include mounting fixtures for securing the carrier to other carrier(s) and/or cargo containers, for instance, using a stacking device(s) with twist locks that engage and lock onto the mounting fixtures.

Abstract: An apparatus, for securely vertically stacking at least one row of side-by-side upper cargo containers with respect to at least one row of side-by-side lower cargo containers, includes at least two rails. Each of these rails has upper and lower mounting fixtures connected thereto so that the rail can be juxtaposed between two rows of upper and lower stacked containers. One of the upper or the lower containers is wider than the other of the upper or the lower containers.
