Abstract: An extraction platform helps disengage a load from a pliant surface by pumping a portion of the pliant surface out from beneath the platform. By forcibly removing portions of the pliant surface, i.e., debris, mud, snow, from beneath the platform housing, any seals, vacuums, tensile forces, or adhesive constituents are broken or disturbed sufficiently, such that the platform housing and the load disengage from the pliant surface. The platform also provides a large surface area for spreading out the weight of the load. The platform includes a mounting surface that joins with the load. A traction surface engages the pliant surface. A pump portion pumps portions of the pliant surface into an intake aperture, and out through a discharge aperture. A drive portion having sprockets and a cable drives the pump portion through momentum forces created by the platform housing, such as articulations of a walking gait.
