Classification Of Trolleys

Trolleys are divided into single wheel, two wheel, three wheel and four wheel. Unicycles can travel on narrow springboards, bridges, and sheep’s intestines. They can steer in place, which is convenient for dumping cargo. Commonly used two-wheeled vehicles include hand-carried vans (also known as tiger carts) that carry items, shelf trucks, and bucket trucks that handle bulk materials. One of the three-wheeled trolleys and two of the four-wheeled trolleys can be turned around the vertical axis (see the swing casters). This type of swivel caster can be automatically adjusted to the direction with the smallest running resistance as the moving direction of the vehicle changes.

Different use trolleys have different body structures. Most four-wheeled trolleys have a cargo platform. Dedicated trolleys have a variety of structures, some of which are box-shaped and suitable for handling light-weight and easy-to-load items; some of the car bodies extend out of the bracket to facilitate the placement of parts such as rods, shafts and pipes; some of the car bodies are completely shaped It fits the cargo, such as a gas cylinder truck; some are very compact and can be folded for easy carrying; some are for the convenience of loading and unloading barreled liquids, paper rolls and other cylindrical goods. Conducive to rolling up and down, such as a cylindrical cargo handling truck. Modern trolleys are equipped with rolling bearings, and the wheels use solid tires or pneumatic tires.
