A tire (American English) or tyre (British English) is a ring-shaped component that surrounds a wheel's rim to transfer a vehicle's load from the axle through the wheel to the ground and to provide traction on the surface over which the wheel travels. Most tires, such as those for automobiles and bicycles, are pneumatically inflated structures, which also provide a flexible cushion that absorbs shock as the tire rolls over rough features on the surface. Tires provide a footprint, called a contact patch, that is designed to match the weight of the vehicle with the bearing strength of the surface that it rolls over by providing a bearing pressure that will not deform the surface excessively. The materials of modern pneumatic tires are synthetic rubber, natural rubber, fabric and wire, along with carbon black and other chemical compounds. They consist of a tread and a body. The tread provides traction while the body provides containment for a quantity of compressed air. Before rubber was developed, the first versions of tires were simply bands of metal fitted around wooden wheels to prevent wear and tear. Early rubber tires were solid (not pneumatic). Pneumatic tires are used on many types of vehicles, including cars, bicycles, motorcycles, buses, trucks, heavy equipment, and aircraft. Metal tires are still used on locomotives and railcars, and solid rubber (or other polymer) tires are still used in various non-automotive applications, such as some casters, carts, lawnmowers, and wheelbarrows.
Forklifts play a very important role in the logistics system of enterprises and are the main force in material handling equipment. Widely used in stations, ports, airports, factories, warehouses and other sectors of the national economy, it is an efficient equipment for mechanized loading and unloading, stacking and short-distance transportation. The purchase of forklifts is very particular, and the purchase of high-quality and inexpensive forklifts can help companies greatly reduce costs. When purchasing a forklift, you should also pay attention to the purchase of forklift accessories, which will bring convenience to future repairs and maintenance. A forklift, the most commonly used parts are forklift tires. Reasonable use of forklift tires is also a cost-saving method. Forklift tires are generally divided into two categories, namely forklift pneumatic tires and forklift solid tires.
Casters are a general term, including movable casters, fixed casters and movable casters with brakes. The movable caster is also called the universal wheel, its structure allows 360-degree rotation; the fixed caster is also called the directional caster, it has no rotating structure and cannot be rotated. Usually two kinds of casters are used in combination. For example, the structure of the trolley is two directional wheels in the front, and two universal wheels in the back near the push armrest. There are casters of various materials, such as pp casters, PVC casters, PU casters, cast iron casters, nylon casters, TPR casters, iron core nylon casters, iron core PU casters, etc. Ergonomic casters are designed with consideration for the operating environment and the task to be performed so that any injurious effects on the operator are minimized. Long-term repetitive actions involving resisting casters can contribute to strain injuries. Improper specifications can also contribute to reduced service life of casters. Many parameters play a role in how well the caster performs. Parameters such as tire hardness, tread width and shape, the length of the trailing offset (the 'caster') and wheel diameter all affect the effort required to start the platform moving. Harder wheels will make the caster easier to roll by reducing deformation resistance. A less inflated tire offers more deformation resistance and thus more effort is required to move the attached platform. Turning effort is affected by the amount of caster and by the wheel diameter. Enhancements to traditional caster design include toe guards, track wipers, reinforced legs, steering tubes, swivel locks and brakes, all implemented in an effort to reduce operator injuries in the workplace.
