Abstract: An apparatus and related method for stocking bulky loads (P) comprising: a storage shelving (2) comprising at least one storage corridor (20) extending in the longitudinal horizontal direction that is divided into two series (22, 23) of support compartments (21), each of which extends itself as a free corridor for the entire longitudinal size and it is adapted for autonomously supporting a row of loads (P); and a lifting means (3) movable on the ground adapted for moving in the longitudinal direction along said storage corridor (20), which comprises a support means (31) which extends vertically, having a relatively small transversal size, which carries engagement means (32), transversally arranged on either side with respect to the support means (31), in order to lift/lower at least preferably two loads at a time, said support means (31) is adapted to pass in an intermediate lane (24) which separates the two series (22, 23) of support compartments (21) and the lifting means (3) is adapted to move the loads (P
