LOAD HANDLING EQUIPMENT - ANORDNING FÖR HANTERING AV BÖRDOR

The invention relates to a device for handling loads used in connection with cranes, which device is used for loading or unloading bricks or other stacked piece goods and which comprises a frame, hooves to be placed under a load and a flap weighing 5 loads from above.

Today, a wide variety of equipment is used to handle brick loads or similar loads. Many of them work well and are fit for purpose.

However, the known devices are not entirely satisfactory. At least two germs are required to handle the load. In large and efficient stackable piece handling equipment, even a single person can control its functions with the help of a remote control system. For small devices, remote control should not be applied as it will be disproportionately expensive.

The object of the invention is to eliminate the above-mentioned drawbacks and, in particular, to provide a load handling device in which one person can conveniently carry out, for example, the transfer of a load by means of a device and a crane. This is achieved by the features of the invention as set out in claim 1.

The advantages of the invention can be considered the lightness of the device, its simple mechanical structure and reliable operation. In addition, it can be easily connected to different types of cranes.

In the following, the invention will be explained in detail with the aid of the accompanying drawings, in which

Figure 1 schematically shows a front view of a load handling device according to the invention 2 64788

Figure 2 shows a side view of the device according to Figure 1.

The load handling device according to the invention is connected to the hydraulic turner 2 of the crane 1, to which the hydraulic hoses 3 are connected. The load handling device consists of a run 8, a hoof 9 moving under a load, such as a brick hose 7, and a flap or cover 5 weighing the load from above. The hooves 9 are attached to pipes 8 'or slides on which they can move in a straight line. The lower surface of the flap 5 is provided with a pad 6 which is 10 e.g. cellular rubber. The claws 9 and the flap 5 are connected to each other by means of a hydraulic cylinder 4 and a lever mechanism 10, 12, 13. A spring load 11 is arranged between the flap 5 and the body 8.

The lever mechanism comprises a vertical beam 13, a lever 10 and an intermediate lever 15 12. One end of the vertical beam 13 is mounted on the claw 9 and the other end on the hydraulic cylinder 4. One end of the lever 10 is mounted on the frame 8 and the other end on the vertical beam 13. 8. The levers 10 and 12 are mounted on the body 8 most preferably via a common body 20.

The load handler works as follows. The device is brought by a crane 1 next to a brick hose 7, which rests, for example, on a truck platform on a suitable platform. By means of the hydraulic rotator 2, the device is placed parallel to the brick hose 7 to be lifted. The center of gravity of the device is arranged so that when the device is lifted, it tilts back slightly from the top. This makes it as close as possible to the bottom of the brick hose 7. When the device is lowered freely on the platform, it presses tightly onto the brick hose. The claws 9 are then guided by a hand-30 valve by means of a hydraulic cylinder 4 under the brick hose. When the claws are in the extreme position, the cylinder continues its movement further and presses the cover 5 provided with the spring load 11 firmly onto the hose. The load is ready to be moved off the platform by crane 1. When removing the brick hose 7 from the device 35, first the spring-loaded cover 5 3 64788 is opened by means of the hydraulic cylinder 4 and then the claws 9 are pulled out from under the hose 7 further using the hydraulic cylinder 4.

The invention has been described above with reference to only one preferred embodiment thereof. It is clear that the invention is not intended to be limited to this embodiment only, but can be modified in many ways. For example, the spring load 11 can be replaced by a suitable counterweight. However, the essential points are set out in the claims.

f
