DE3020055A1 - Forklift truck for piece goods - has forks on telescopic slewing boom, with counterweight and telescoping support roller - Google Patents

Abstract

The forklift truck is particularly intended for loading and unloading piece goods. It has lifting forks on a telescopic boom, the latter mounted on a slewing ring (5) on the top of a travel chassis (8). Thus the truck can pick up and set down palletised loads in both the longitudinal and radial direction. A support roller (3) on a telescoping mounting is provided on the forks, while a tailweight (7) can be mounted at the rear end of the boom. The roller can be actuated, in order to counteract the tipping moment as necessary, and the chassis can be mounted on steerable wheels or crawler tracks.

Description

Description and explanation of the patent application

"Mobile pallet loader with rotatable and telescopic design It is known to use general cargo loaders such as forklift trucks.

However, these have a limited pick-up and drop-off area.

With the forklifts, the pallets are picked up, lifted, and through an additional turning movement of the forklift, for example, the piece goods transported to the respective location.

It is not a continuous material posting from one location of the Forklift possible.

Furthermore, it is necessary that for loading trucks many times the side brakes are folded down and the entire tarpaulin structure dismantled have to use a forklift truck to cover the relatively wide loading area of the truck from both To be able to load pages - or it has to be from the rear face the loading can be carried out, but with the help of another transport device, such as pallet carts and the like, to then manually on the loading area of the truck or the railroad car to store the piece goods in a space-saving manner.

In order to overcome these disadvantages, a pallet loader has been developed according to the invention that is capable of loading from the rear of the truck or can also be carried out from the side hatch of a railway wagon, without additional Having to use two units for moving on a straight surface.

The loading task or the unloading task is carried out according to the invention solved in that a mobile pallet loader according to the accompanying drawing Applies.

The invention according to the accompanying drawing works as follows: A telescopic roller (3) is attached to the end of the lifting fork (2), which acts as a support roller is arranged adjustable.

The task of the telescopic roller is to move the pallets from the pick-up position up to: the point where the lifting work is carried out, in the desired position to drive.

Through this device according to the invention there is no additional bending moment required for the telescopic fork (4) according to the invention.

After the lift is carried out by the lifting fork (2), it can the telescopic fork (4) can in principle rotate up to 360 and can place the pallets on the Loading areas of the truck, e.g. over the rear face.

Figure I shows the sliding telescopic fork.

Figure II shows the deposited piece goods (1), with the telescopic fork (2) can be moved with the support roller (3) on the loading area.

When the pallets are put down, the telescopic roller (3) lies on the Loading area, so there is again no additional moment for the undercarriage (8).

The telescopic fork (4) in FIG. III now extends as far as it does the required loading of the truck or

of the container or another loading area is.

The lifting fork, which is adjustable, is arranged at the desired delivery location is released from the pallet, retracted telescopically and as desired a turning movement back to the desired starting position to pick up new ones Pallets swiveled or driven.

This loading, which has to be carried out from one location, is only possible through the inventive combination of a telescopic telescopic fork made economically justifiable with the telescopic roller support.

The undercarriage (8> is designed so that it has its own drive forward or by swiveling the wheel axles (9) in all necessary directions can move righteously.

Furthermore, it is proposed according to the invention, as can be seen from FIG. III, that the forks also point towards 11 or 1? be postponed and that even smaller pallets can be stowed in corner areas.

The pallet loader can optionally be fitted with normal tires as a chassis have and / or be provided with a crawler track.
