Abstract

A method of loading goods into and unloading goods from narrow spaces located some distance above ground level is disclosed. In the method, use is made of a specially designed loading truck with a drive and steering apparatus which can be driven from one place to another and including a cargo lifting apparatus suited for lifting an entire transport carriage of cargo. The apparatus also includes a lift for vertically lifting persons adjacent to the cargo lifting apparatus to thereby provide free access to the load platform. In the method, the truck is driven to the location where the cargo is standing, the cargo is lifted by the truck, the truck is driven to a position adjacent to the unloading place, the transport carriage is lifted until the uppermost layer of cargo is level with the unloading place, and the person lifting device is lifted to a convenient position adjacent the cargo and luggage is unloaded.

Method of loading goods into and unloading goods from a hold of an airplane located at least some distance above the ground level, while using a specially designed load truck including a drive means and steering means (1) so that the truck can be driven from one place to another, a load lift means (2) having a load platform (7) suited for lifting a complete load unit comprising a goods transport carriage (11) together with goods (14) loaded thereon, and a person's lift platform (8) capable of lifting a person a predetermined distance up and down respectively into and from a suitable position for handling of goods lying on a floor (13) of the hold and lifting an uppermost layer of a luggage unit on the goods transport carriage (11) respectively, and formed so that the person can move himself standing on the person's lift platform into a position right in front of a hold opening, whereby the loading and unloading is made in the same way but in inverse order, comprising the steps of:

driving the truck to a place where the goods transport carriage (11) with goods (14) is standing;
lowering the load lift means (2) and positioning said lift means at a position underneath the goods transport carriage (11);
raising the load lift means (2) so that the goods transport carriage (11) is lifted free of the ground;
driving the truck with the goods transport carriage (11) to a suitable position adjacent a loading/unloading place, and so that the person's lift platform is in position in front of a hold opening;
raising the person's lift platform (8) independently of the load platform so that the person is positioned at a suitably high working unloading position in relation to the hold;
raising the load platform (7) independently of the person's lift platform so that an uppermost layer of goods (14) is positioned at a suitable unloading/loading position for the person;
unloading the goods (14) by successively lifting off the uppermost layer of goods on the goods transport carriage;
raising the load platform (7) intermittently during unloading of the goods so that an uppermost layer of goods (14), at any moment, is always in a suitable loading/unloading position;
and
after the unloading of goods (14) from the goods transport carriage (11), or the loading of goods (14) from the hold to the goods transport carriage (11), is finished, lowering the person's lift platform (8) and the load platform (7) and moving the truck together with the goods transport carriage (11) away from the loading/unloading place.
