DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The present invention concerns an apparatus for handling containers, load pallets or equivalent similar articles and the construction of a container, load pallet or equivalent article handled with the apparatus.
Numerous apparatus for handling containers and load pallets or other equivalent load units are known in the art in which the container or similar load unit has been disposed to move onto the chassis of the transport vehicle with the aid of separate cylinder apparatus and cam mechanisms. In such designs of the prior art, an auxiliary body is tiltable relative to the vehicle chassis with the aid of the cylinder apparatus, and the auxiliary body is provided with separate gripping means by means of which the container or similar load unit can be hoisted up on the auxiliary body. Removal of the load from the auxiliary body is similarly performable with the aid of separate power means or by the aid of gravity.
A drawback of prior art apparatuses that the load container cannot be lifted to a height greater than the transporting height. Moreover, in apparatus designs of the prior art the gripping cams are constantly prominent e.g. by effect of a spring. This mechanism imposes extra limitations on the handling of the goods container. Therefore when it is desired to load containers on top of each other, the vehicle has to be fitted with extra hoisting equipment. The use of fork lift trucks, for instance, to accomplish such stacking tasks is known in the art. Therefore when load pallets placed in storage are being unstacked, similar dismounting means have to be employed, and therefore the means which are known in the handling of conventional load pallets cannot be considered in problem solutions conforming to the state of art when pallets are being dismounted from stacks.
SUMMARY OF THE INVENTION
The object is a apparatus with which a container, pallet or equivalent unit can be handled in such manner that the unit can be lifted to a greater height than the transporting height. Such an apparatus also has an an object to in mines in narrow and low-ceilinged tunnels and heads of galleries. The aim is furthermore, specifically, an apparatus intended for transporting containers, pallets, tanks, working units or similar articles when in the transport in question transport systems based on fork lift trucks or the like are not suitable.
The handling apparatus of the invention is mainly characterized in that the means comprises a tilting cylinder between the body and the auxiliary body and a lifting cylinder between the body and the auxiliary body, and an intermediate lever pivoted at one end with a joint on the auxiliary body and at the other end with a joint on the body, and the apparatus comprising members on the auxiliary body by which the container or equivalent can be moved onto or off the auxiliary body, whereat with the apparatus loading of a container or equivalent or unloading of a container or similar object may take place on a level higher than the transporting height.
The load unit which is handled with the handling apparatus of the invention is mainly characterized in that the container, load pallet or similar load unit comprises a plurality of stop members, the cam lever of the handling means being placeable in alternative positions between different stop members.
The load can be moved from one point to another with the handling apparatus of the invention. Loading and unloading can be performed from a plurality of different levels, varying from ground level to a level which is considerably higher than the transporting level. This particular feature enables containers to be stacked within a wide height range, and it is possible in addition, with the means of the invention, to perform loading and unloading from/onto loading ramps which are greatly variable in height. The handling apparatus of the invention is moreover controllable by one man from the cab of the vehicle. All control manipulations that are required are performable from the driver's cab.
