Description

Technical Field

[0001] The invention belongs to the technical field of forklifts, and in particular relates to a flexibly adjustable traction tooling for a forklift. Background Art

[0002] Currently, the domestic forklift industry generally adheres to the national standard GB / T18849-2011, "Powered Industrial Vehicle Brake Performance and Component Strength," when conducting drawbar pull tests. During this test, the vehicle being tested must be paired with a forklift of a larger tonnage. A tension rope, coupled with sensors and clips, is used to connect the front and rear vehicles directly at the drawbar pins for measurement.

[0003] However, due to the varying counterweight structures of various vehicle models, the drawbar height varies significantly. The pull rope and sensor are angled, and the height difference from the vehicle's center of mass is also significant, affecting the measurement results. To enter the European market, the entire vehicle must undergo CE certification. The latest European forklift standard, ISO 6292-2020, has new requirements for drawbar pull tests, requiring the drawbar height to be the same as the vehicle's center of mass, or 900mm if the vehicle's center of mass is higher than 900mm.

[0004] According to relevant surveys, when testing the drawbar tension of most forklifts, the height of the tow pin is significantly different from the height of its center of gravity or 900mm above the ground, making it impossible to measure directly. Therefore, the current measurement method cannot meet this requirement, and there is currently no tooling or equipment in the industry that can meet this requirement. Summary of the Invention
