Trolleys for different purposes have different body structures. Most general-purpose four-wheel trolleys have a cargo platform. Special trolleys have a wide range of structures, some of which are made of the box shape, suitable for carrying lightweight and easy to load and unload items; Some car bodies extend out of the bracket to facilitate the placement of rods, shafts, pipes and other parts; Some car bodies are completely consistent with the goods, such as gas cylinder cars; Some are very small, foldable and easy to carry; In order to facilitate the loading and unloading of barrel goods such as barreled liquid and paper roll, there are two flat sheets of steel on the car body to form a low inclined plane, so as to facilitate the rolling up and down of barrel goods, such as barrel goods loading and unloading vehicle. Modern trolleys are equipped with rolling bearings, and the wheels are made of solid tires or pneumatic tires.
The anti-static trolley is made of stainless steel framework, wire mesh plate, steel column and anti-static nylon wheel. The four corner columns of the mesh plate are equipped with adjusting clips and slots, which are light and flexible. The steel column is recessed into the groove ring every one inch and assembled with the protruding coil of the nozzle piece. It can adjust the required height and effectively discharge the electrostatic charge according to the needs. It is fast to adjust and easy to use. It is strong and durable. The laminates are divided into mesh and plate. The bridge structure has uniform load-bearing distribution.
The silent trolley is novel and beautiful. The use of synthetic plastic bodies and casters reduces the dead weight of the whole vehicle. The unique mute and transmission technology design makes the trolley walk silently and briskly. It is widely used in material handling industries such as factory areas, office buildings, libraries, hotels, the catering industry and logistics transportation.
Trolleys have different specifications according to different needs (such as single-layer, double-layer, manual pull, manual push, etc.), and they need to be reasonably selected according to the weight and size of the loaded object.
The types of trolleys also include two-wheeled vehicles and single-wheeled vehicles, which are still used in some rural and mountainous areas in China. The wooden unicycle once played an important role in the movement of supporting the front in China's war of liberation.
Trolleys are made of stainless steel, steel, plastic, aluminum and so on. Stainless steel carts are widely used in food, medical, chemical and other industries. Steel carts are widely used in industry, storage, electronics and other industries. Plastic and aluminum carts are generally used in small warehouses, stores, shopping malls and other industries because of their light material and convenient carrying.
