Description

Technical Field

[0001] This invention belongs to the field of brake-stopping trolley technology, specifically relating to a semi-aluminum traction brake-stopping trolley. Background Technology

[0002] A trolley is a mobile device that can be customized to meet the needs of different scenarios, and is mainly used for transportation, work support or equipment integration.

[0003] Existing trolleys generally suffer from low efficiency and insufficient safety in cargo transportation. Current trolleys, constructed entirely of steel, are heavy, difficult to move, and lack effective braking devices, making them prone to slipping on slopes or smooth surfaces, leading to cargo damage or safety hazards. Furthermore, existing trolleys are single-unit designs, unable to be flexibly linked, requiring manual handling one by one, which is time-consuming and labor-intensive. When transferring goods to higher locations, forklifts are needed for repeated adjustments, making the operation cumbersome. While some trolleys have simple railings, they lack adjustable limit devices, making it easy for goods to spill out. Existing technologies have not yet offered effective solutions to these problems: all-aluminum trolleys, while lightweight, lack sufficient strength; linked trolleys have complex structures and are difficult to assemble and disassemble; braking systems often rely on external tools and cannot respond quickly. Therefore, there is an urgent need for a semi-aluminum traction and braking trolley that combines lightweight design, efficient braking, modular linkage, and convenient loading and unloading to improve transportation efficiency and safety.
