AI Technical Summary

Technical Problem

Traditional flatbed trucks are difficult to adjust their posture to pass through thresholds or obstacles, resulting in low handling efficiency and severe wheel wear, which shortens their lifespan with long-term use.

Method used

Eight symmetrically arranged mobile devices are installed at the bottom of the flatbed truck in two rows and four columns. The wheels can be folded and retracted by pulling the handle. Combined with the design of wear-resistant layer and tension spring, the stability and wear resistance of the wheels are ensured when crossing thresholds or obstacles.

Benefits of technology

It improves the ease and efficiency of crossing thresholds or obstacles, reduces wheel wear, lowers the risk of damage to thresholds or obstacles, and enhances the stability and service life of the flatbed.

Abstract

This utility model relates to the field of material handling equipment technology, and in particular to a flatbed truck capable of crossing thresholds or obstacles. It includes a flatbed truck body, with a push handle fixedly connected to the upper right side of the flatbed truck body. Eight moving devices are arranged at the lower end of the flatbed truck body. Each moving device includes a mounting base with a first recessed opening at its lower end. A connecting component is rotatably connected within the mounting base, and a tension spring is fixedly connected to the right side of the connecting component. A wear-resistant layer is fixedly connected to the outer surface of each moving wheel. The mounting base is fixedly connected to the lower end of the flatbed truck body. This utility model provides a flatbed truck capable of crossing thresholds or obstacles. Through its foldable wheels and symmetrical distribution design, the flatbed truck can efficiently cross thresholds and other obstacles without manual lifting. Simultaneously, the wear-resistant layer and balanced structure reduce equipment wear and the risk of tipping over, ensuring stable transport of goods.
