Description

Technical Field

[0001] This utility model relates to the field of forklift technology. Background Technology

[0002] There are two structural designs for the forks of telescopic forklifts, as follows: One type of fork is forged from a single piece, with the vertical and horizontal sections forged together. It is mounted on the fork carriage using a hook or sleeve at the end of the vertical section. Two forks are used in pairs, and this type is widely used. Figure 1 As shown.

[0003] Another type of fork consists of a vertical section and a horizontal section hinged together. The vertical section is mounted on the fork carriage using two hooks or sleeves, while the horizontal section is supported and limited at the hinge point. Two forks are used in pairs. Figure 2 As shown.

[0004] The inventor of the utility model has discovered at least the following problems in the prior art: The first structural design, where the vertical and horizontal sections are forged as a single piece, requires ensuring that the two forks are mounted flush on the fork carriage. This necessitates a high degree of consistency in the angles between the vertical and horizontal sections, increasing the forging difficulty and processing costs. Furthermore, when the forklift is in motion, the forks need to be manually flipped backward to retract. The integrated forging structure of the vertical and horizontal sections results in a large overall mass and a long flipping distance, making it quite strenuous in actual operation and posing a risk of the forks slipping out of one's hands and causing injury.

[0005] The second structural design involves hinged vertical and horizontal fork sections. The hinge point serves as the fulcrum for the horizontal fork, allowing it to rotate around this point. The rotation of the horizontal fork is restricted by the lower structure of the vertical fork, ensuring that the two forks are perpendicular under load. This contact point acts as the resistance point for the horizontal fork. However, this design results in a shorter distance between the fulcrum and resistance point, leading to a smaller resistance arm. Furthermore, the hinged structure weakens the overall strength of the fork, causing the supporting section to experience significantly higher torque than other parts under heavy loads. This uneven stress distribution increases the risk of breakage over prolonged use. Additionally, the overall structure is complex and heavy. Utility Model Content
