The invention relates to a transfer plate for loading a cargo space. The transfer plate is intended to be moved, together with cargo units, into the cargo space and back again, the cargo units remaining in the cargo space. Rolling elements are arranged, over at least part of the length of the transfer plate, on the side of it facing the cargo units to permit movement between the transfer plate and the cargo units. The transfer plate is mainly of plastic and the thickness of the structure formed by the transfer plate and the rolling elements are less than 70 millimeters. The invention also relates to a method for loading a cargo space.

1. A moveable transfer plate for loading a cargo space having a delimiting bottom structure, said transfer plate being moveable together with a load of cargo units into the cargo space and back again, the cargo units remaining in the cargo space, said moveable transfer plate comprising: a frameless longitudinally extending flexible plastic sheet without any rigid continuous frame, said flexible plastic sheet being arranged to withstand pushing and pulling with cargo loaded thereon;said flexible plastic sheet having an upper cargo facing surface and an opposite lower surface;said flexible plastic sheet upper cargo facing surface including a track roller portion including a plurality of longitudinally extending track rollers, each track roller including rolling elements permitting movement between the transfer plate and the cargo units, and said flexible plastic sheet upper cargo facing surface also including a ramp portion adjacent said track roller portion;a combined thickness of the flexible plastic sheet and the rolling elements is 70 mm or less;said ramp being at the same elevation of the rolling elements adjacent said track roller portion and longitudinally tapering toward an end of the transfer plate and having a thickness of 5-20 mm at said end thereof; andsaid opposite lower surface of said flexible plastic sheet is smooth and continuous at least in the length of said track rollers and arranged to slide over the delimiting bottom structure of the cargo space. 2. The moveable transfer plate according to claim 1, characterized in that the thickness of said transfer plate is 40-70 mm. 3. The moveable transfer plate according to claim 1, characterized in that said track roller portion includes track rollers covering essentially the entire width of the flexible plastic sheet. 4. The moveable transfer plate according to claim 1, characterized in that, in the direction of the width of the flexible plastic sheet, the track rollers are arranged such that said rolling elements are at different points relative to each other in the longitudinal direction of the flexible plastic sheet. 5. The moveable transfer plate according to claim 1, characterized in that said rolling elements are freely rotating rollers. 6. The moveable transfer plate according to claim 1, characterized in that the ramp length is 500-3000 mm. 7. A method for loading a cargo space having a delimiting bottom structure, said method comprising the steps of: loading cargo units onto a transfer plate including a frameless longitudinally extending flexible plastic sheet without any rigid continuous frame, the flexible plastic sheet being arranged to withstand pushing and pulling with cargo loaded thereon, the flexible plastic sheet having an upper cargo facing surface and an opposite lower surface, the flexible plastic sheet upper cargo facing surface including a track roller portion including a plurality of longitudinally extending track rollers, each track roller including rolling elements permitting movement between the transfer plate and the cargo units, and a ramp portion adjacent said track roller portion, a combined thickness of the flexible plastic sheet and the rolling elements is 70 mm or less, the ramp being at the same elevation of the rolling elements adjacent said track roller portion and longitudinally tapering toward an end of the flexible plastic sheet and having a thickness of 5-20 mm at said end thereof, and the opposite lower surface of the flexible plastic sheet is smooth and continuous at least in the length of said track rollers and arranged to slide over the delimiting structure of the cargo space,moving the transfer plate together with the loaded cargo units, into the cargo space by sliding the lower surface of the flexible plastic sheet over the delimiting bottom structure of the cargo space, andsubsequently moving the transfer plate out of the cargo space by pulling the transfer plate out from underneath the cargo units, thereby leaving the cargo units to remain in the cargo space. 8. Method according to claim 7, wherein a conveyor system is used to deliver cargo units to said transfer plate. 9. Method according to claim 7, characterized in that the transfer plate is moved using transfer devices, and the cargo units are pushed by a filling device onto and off of the transfer plate.
