Inventor: HANN SIMON
IPC: B60P1/64
Filed: 2011-09-27
Abstract: A collapsible intermodal transport platform and methods for its operation are disclosed. The invention comprises structural ribbings that rotate about an axle disposed beneath the loading surface of the platform. The ribbings are positioned along the platform so as to provide lifting and stacking fitments at the standard overhead crane lifting points when in a lift configuration. The ribbings may be rotated inboard down to the loading surface, thereby presenting stacking blocks at the crane lifting points for stacking several platforms together. Alternatively, the ribbings may be rotated outboard to accommodate full size loading of cargo. The ribbings are rotated under electric or hydraulic power, according to the various embodiments disclosed. The stacking blocks provide flip-up fitments for use when the ribbings are in a lowered configuration for stacking transport platforms with other transport platforms or with standard intermodal containers. The stacking blocks may be lifted directly or may be locked in to adjoining fitment housings, such that the transport platform will cling to the adjoining platform or intermodal container above it that is being lifted. Other features and aspects disclosed lend to the invention's low weight and high carrying capacity, as well as its unique load securing features.
