The invention relates to a Method and a device in lowering/lifting a carrying deck panel (11) for carrying cars/trucks inside a hold aboard a Pure CarlTruck Carrier (PCTC), while using at least one lifting device (1) having lifting means applied under said deck panel (11) being reversibly raisable and/or extendable and/or liftable and/or lowerable to lift or lower said deck panel (11). Said lifting means (9, 10, 15) are applied at a number of choice specifically calculated for each deck panel (11) dependent upon which panel is to be lifted/lowered. The lifting means (9, 10, 15) is/are to be controlled from rest position/-s to provide a distributed lifting force pattern below said deck panel (11) to lift or lower the same by applying lifting force/-s in an individually controllable pattern thereon, so that the deck panel (11) when in an unloaded state can be lowered and lifted undeflectedly or deflected in a predictable fashion.
