ABSTRACT:
A displaceable flooring system for particular use on truck trailers includes a movable second floor portion, and control structure for elevating and guiding translational displacement of the movable floor portion into a position at least partially superimposed above an adjacent first floor portion in order to selectively create a floor opening left by the displacement of the movable floor portion. The control structure includes a driving mechanism for elevating an end of the movable floor portion normally aligned adjacent to the abutting end of the first floor portion, and a roller system is provided to enable translational rolling of the movable floor portion over the fixed, first floor portion.
