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

tires is also a cost-saving method. Forklift tires are
generally divided into two categories, namely forklift
pneumatic tires and forklift solid tires.

<a href="http://www.blyshares.com/casters/"
target="_self">Casters</a> 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.
