Description

Technical Field

[0001] The utility model relates to the technical field of civil engineering construction, in particular to a material transport frame structure used for civil engineering construction. Background Art

[0002] Although material handling technology continues to develop, wheelbarrows are still used as an indispensable handling tool, especially in construction sites of civil engineering projects. Wheelbarrows are widely used in production and life because they are low-cost, simple to maintain, easy to operate, and light in weight. They can work in places where motor vehicles are inconvenient to use. They are very convenient for carrying lighter items over short distances. They save effort, time, and money. Wheelbarrows are divided into single-wheeled, two-wheeled, three-wheeled, and four-wheeled. Wheelbarrows can travel on narrow springboards, temporary bridges, and goat paths. They can turn on the spot and are very convenient for dumping goods. Commonly used two-wheeled vehicles include hand-pushed transport trucks for carrying pieced items, also known as tiger carts, rack carts, and bucket trucks for carrying bulk materials.

[0003] There is one swivel caster in a three-wheeled trolley and two in a four-wheeled trolley that can rotate around a vertical axis. The swivel caster can automatically adjust to the direction with the least running resistance as the vehicle's moving direction changes during operation. However, the front end of the existing trolley lacks a limiting and fixing device for the movable legs, and some trolleys lack a device for limiting the position of transporting building materials such as square steel and steel bars, which brings great inconvenience to construction workers and cannot meet people's needs.
