AI Technical Summary
When the existing forklifts transport the oversized diameter tower joints in reverse, the lifting height cannot independently fork the barrel joints, resulting in unclear vision and difficult operation during the reverse transportation.
An oversized diameter cylinder section inverted forklift tooling is designed, using structural combinations such as limit columns, cross beams, vertical beams and oblique braces. By adjusting the lifting height of the tooling, the fork frame is always within the driver's sight and ensures that the operating field is clear.
It achieves safe and secure backward transportation of a single-section tower between 7m and 9.5m, ensuring a clear vision for the driver, a strong and durable structure, and is suitable for large-diameter barrel backward transportation forklifts.

It is used for the production of tooling for large diameter tower single section forklift inverting. The applicable scope of the tooling is: 9.5≥maximum tower diameter≥7.5m. The tooling surface is deburred and sharp corners are blunted. All welds are continuous welds. The box beam and I-beam structure welding must be carried out according to full penetration. The rest are fillet welds. The weld leg height is 0.8 times the thinnest plate of the joint. Thick, C20 through-welding holes should be opened above and below the web of the crossbeam at the connection between each longitudinal beam and crossbeam, and each diagonal brace should be adapted to the beveled mating surface according to the installation position shown in the figure. The materials used can be replaced by other materials that meet the strength and design requirements. It must be confirmed by technical personnel before use. This tooling is suitable for the reverse transportation of single-section tower forklifts with a maximum diameter of 7m to 9.5m. When the reverse cylinder diameter is greater than 7.5m, the fork tine frame should always be kept above the driver's line of sight. When the reverse cylinder diameter is 7.5m>d>7m, the fork tine frame should always be kept below the driver's line of sight. When in use, fork in from the fork space 11. When in use, adjust the lifting height of the tooling according to the actual situation to ensure that the driver has a clear field of vision during the reverse transportation of the cylinder section. The above completes a series of operations of the forklift tooling for the reverse transportation of the super-large diameter cylinder section.
