DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
The present invention generally relates to a method and and apparatus for loading and unloading of goods into and from narrow spaces, and the invention is more particularly concerned with loading and unloading of goods into and from highly located spaces, especially into and from spaces having a low ceiling height.
The invention has especially been made as a solution of the problem of loading and unloading of goods into and from cargo or luggage holds of air planes, and the invention will mainly be described in connection to such field of use. It is, however, obvious to the expert that the claimed method and apparatus are useful for many other purposes and within many other technical fields.
BACKGROUND OF THE INVENTION
Loading and unloading of cargo or luggage to and from air planes is a hard, stressful and crampy job. So far three persons have generally been involved in the work consisting of loading of cargo or luggage from a transport carriage standing on the ground to its final place in the cargo hold of the air plane, and unloading of the cargo or luggage from the cargo hold of the air plane to the transport carriage on the ground, respectively.
The loading has generally been made in that one person drags a carriage filled up with cargo or luggage to a position adjacent the air plane, a first loader man lifts and carries the luggage from the transport carriage to a conveyor belt extending from the ground to the luggage hold of the air plane, on which conveyor the luggage is transported as far as to the hold hatch of the air plane; a second loader man, who is sitting on his heels close to the opening of the narrow, often only 90 cm high hold, receives the luggage from the conveyor and throws it further into the hold; a third loader man, who is likewise sitting on his heels at the inner end of the hold receives the luggage (cargo) from the second loader, lifts the luggage, turns round together with the luggage and stows the luggage as deep in the hold as possible.
The job environment is very straining, especially for the second and the third loader persons. The loaders are sitting on their heels in the low, often only 90 cm high luggage hold, and they have to lift and carry the luggage, to rotate together with the luggage, and they have to throw or stow, respectively, the luggage which can be of the most various shapes and can have very varying weight. The loaders further work under great press of time, since it is many times depending on the loader persons if the air plane can keep its time schedules.
Also, the above mentioned first load attending person has a hard job involving, at least in some cases, to drag the transport carriage as far as to the load band conveyor, and also to lift and carry the luggage or cargo from the transport carriage to the conveyor. Especially in winters there can be skid accidents when the transport carriage, which is often very heavy, has to be dragged from the parking place as far as to the hold conveyor.
The object of the invention therefore is to solve the problem of providing a method and an apparatus for facilitating the job with loading of goods into and unloading of goods from highly located, narrow spaces like luggage or cargo holds of an air plane.
SUMMARY OF THE INVENTION
According to the invention there is made use of a specially designed loading truck formed with drive and steering means so that it can be driven from one place to another, a cargo lifting means suited for lifting of the entire transport carriage with the luggage or cargo, and a person's lift for making it possible to lift the driver a certain distance up and down respectively into a suitable position for handling, on any occasion, the uppermost layer of luggage on the transport carriage. In this case the driver of the truck is the same person as the above mentioned first loader man.
An important feature of the apparatus of the invention is that the person's lift and the load platform are formed without any uprights, so that there is a free access between the loadin
