A fully loaded flatrack can be self-loaded and self-offload by an LVS MK18A1 without the aid of additional material handling equipment and by an LVS MK18 equipped with container lifting and loading chains. There are no hydraulic, air or electrical connections or equipment on an MK1077. The Palletized Load System (PLS) is also used with the LVSR MKR18 Cargo Variant.
