The invention relates to a loader-pulling device that includes "for example on the swing dock leveler of a truck, a trailer or the like. is attached, which can be moved backwards during the tilting process, so that you rear end comes into contact with the ground or another subsurface and the one at the front end Hydraulic Hotor owns that at both ends of its drive shaft is provided with chain wheels between the profile frame girders of the swing bridge so that chains are attached that run around these sprockets and around wheels that are at corresponding points at the rear end of the swivel bridge are located.

The load puller according to this invention is essentially characterized in that it consists of two Trolleys, which are connected to a cross member, consists on which known fasteners for gripping des Containers.drehbar are mounted and that the trolleys have a transport wheel located near the cross member and a carrier wheel somewhat further away from the cross member have and that the trolleys on the to the rear-'ren Ends of beveled I-profile beams are guided, -so that the transport wheels on top of the Profilträgerräiidern the swivel bridge and the carrier or guide wheels on the side the profile girders of the swivel bridge run on the lower bands of the upper profile girder flanges and that the Chain ends at suitable points on the trolleys of the pulling device are attached, so that when the swing bridge is inclined and lowered, the fasteners are loose Can grab the platform or the container in order to pull it onto the swivel bridge with the help of the pulling device.

The object of the invention is to realize a charging device in which no very large expenditure of force for the slight lifting is required at the beginning of the loading process, so that the effort required during the whole Charging process remains almost constant. This is achieved by the device according to this invention, the device is moved approximately in a straight line on the swing bridge the entire time. The main advantage of the invention lies in the fact that considerable cargo can be loaded without the risk of possible damage and without the use of a hydraulic motor large power can be pulled onto the swing bridge.

It is also advantageous that, despite the rectilinear movement of the trolleys, the transport rollers of the pulling device according to FIG this invention can be brought very close to the loose platform or to the container.

The invention is hereinafter described with reference to "enclosed Drawing explained in more detail; in the drawing shows:

Fig. 1 is a side view of the pulling device according to this Invention in a position after attaching the fasteners at the container,

Pig. Fig. 2 is a side view of the pulling device according to this Invention while pulling the load onto the swing bridge, and

FIG. 3 shows the device according to FIG. 2, seen in direction A. FIG of Fig. 2.

In Figs. 1-3, the swivel bridge is always in the tilted position shown, so that the support wheels 20 touch the ground at the rear end of the swivel bridge 1. The rear ends of the Profile supports 2 and 3 of the swivel bridge 1 are beveled so that the slope in the above position of the swivel bridge in runs approximately parallel to the ground and the upper flange 17 of the profile supports 2 and 3 with an I-shaped cross-section almost reached the bottom. A hydraulic Hotor 4- is at the front End of the swing bridge attached, and chain wheels 9 are on the shaft ü of the hydraulic motor 4 between this and the profile beams 2 and 3 attached. According to the sprockets 9 are at the rear end of the swivel bridge 1 mating wheels 10, each with a pair of wheels 9 and 10 a chain 5 between the profile beams of the swivel bridge and the ends of the chains 5 with the trolleys 11 are firmly connected. The fastening points 18 and 19 are preferably chosen so that they have a torque against the charge 16. A guide wheel 13 on the front side of each trolley 11 runs below the upper flange 17 of the profile beam 2, 3 on the lower edge of the upper flange 17> while a on the trolley at a suitable distance behind the guide wheel 13

309831/0447

Transport wheel 12 brought in to take the weight of the load 16 and runs on the upper edge of the profile beam 2, 3. A cross member 7 »which connects the trolleys 11 to one another, has rotatable fastening elements 15 at its ends, which arrangements can be of any kind, provided that they serve their purpose.

The following is the operation of the charging device Described in more detail according to this invention.

The swivel bridge 1 is tilted and by means of a suitable device in a position according to FIGS. 1 and 2 in the immediate vicinity Near the container 16 lowered, the support wheels 10 at the rear end of the swing bridge 1 the Touch the ground. The loading and pulling device 6 is to the rear, brought the lower end of the swing bridge 1 by means of a hydraulic motor 5 and chains 5.

On the attachment points 19 of the chains 5 is special pointed out, which are at the foremost point of the pulling device 6 and an extension of the trolleys to the allow the extreme end of the swivel bridge in the position of FIG. Pedal when reversing the truck now the fasteners 15 in the openings at the end of the container 16 and lock there. The hydraulic motor 4, which is then put into operation, rotates the wheels counterclockwise according to FIGS. 1 and 2, and the chains 5 now pull the container 16 with the aid of the above Trolleys 11 on the swivel bridge 1, with side guides 21 at the rear end of the swivel bridge 1 a lateral Prevent the container 16 from breaking out. The pulling device runs approximately in a straight line on the swivel bridge 1, and suitable, Stop devices provided with switches on the swing bridge limit the end points of the movement of the Pulling device 6. The backward movement of the container

or the loose platform 16 away from the swing bridge "" happens in reverse order.

The fasteners engage - as described and in iPig. 1 - into the openings at the lower corners of the container 16. The container 16 is placed on the swivel bridge pulled, its rear end remains firmly on the ground while the truck is backing up and pushing the swing bridge under the container. The pulling device lifts the front end of the container 16 as in Pig. 2 shown so that the container 16 with respect to the Trolleys 11 rotates around points 14-. The front end and bottom of the container 16 remain in place during loading a distance from the swing bridge 1 and its device.

If the container 16 is on an incline, the Swing bridge inclined laterally according to the ground be, oo that the fasteners 15 also so in the openings at the end of the container. In this case, charging is just as easy to perform as it is on flat G-round
