In one embodiment, as shown in FIG. 1, the forklift spreader provided by the present invention comprises a main bracket 1, as shown in FIG. 2, FIG. 3 and FIG. 4, the main bracket 1 is connected with a sliding frame 2; Based on this, as shown in FIG. 1, the sliding frame 2 is further connected with an attachment for container lifting. The attachment includes a main beam 4 connected to the sliding frame 2, and the main beam 4 can slide along the horizontal direction of the main bracket 1 through the sliding frame 2; the telescopic beam 5 is connected to both sides of the main beam 4, and the telescopic beam 5 The lock bracket 6 with a fixed container is connected.

Based on the prior art, the skid frame 2 of the heavy forklift spreader provided by the present invention is further connected with an attachment for container lifting. The forklift spreader includes a main bracket 1 to which a slip frame 2 is attached, and then an attachment for container lifting is attached to the slip frame 2. Compared with the prior art, the present invention replaces the forked fork knife with the attachment for the container hoisting, and can only lift the 20 ft container with respect to the fork knife, and the attachment can hoist the 20 ft container and hoist 40 ft. The container is thus able to lift large containers. In addition, the attachment is designed for lifting containers, so the safety of lifting is improved.

It should be noted that the above technical solution does not limit the structure of the attachment for container hoisting, and therefore any structure of the attachment for container hoisting should be within the protection scope of the present invention.

Specifically, in the above technical solution, as shown in Figs. 1, 2 and 5, the forklift hanger further includes a transition frame 3, and the attachment is further connected to the slide frame 2 via the transition frame 3. This structural design facilitates the connection of the attachment to the sliding frame 2, and the structure is relatively simple, and the reliability of the connection is high.

Based on the above technical solution, the connection structure between the transition frame 3 and the sliding frame 2 can be specifically designed. For example, the upper portion of the sliding frame 2 is provided with a card slot; as shown in FIG. 2 and FIG. 6, the upper portion of the side of the transition frame 3 opposite to the sliding frame 2 is provided with a buckle 31, and the buckle 31 is mounted on the card In the card slot. The connecting structure realizes the connection and positioning of the upper part of the transition frame 3 and the sliding frame 2, the connection reliability is high, the structure is simple, and the processing cost is low.

Specifically, it is also possible to specifically design the connection structure between the lower portion of the transition frame 3 and the lower portion of the slide frame 2. For example, as shown in FIG. 6, the lower portion of the side of the transition frame 3 opposite to the sliding frame 2 is provided with two connecting plates 32; as shown in FIG. 5, the lower portion of the sliding frame 2 is disposed on the two connecting plates 32. In the gap, and the outer ends of the two connecting plates 32 are connected by bolts.
