Cart's casters casters casters casters the history of plant 

 To trace the history of caster is a very difficult task, but in people invented the wheel, the handling and moving objects much easier, but the wheels can only be run in a straight line, for handling a major change of direction when the object is still very difficult, then people move on with the invention of the wheel structure, which is what we now call the caster or caster. Casters appear to the people handling moving objects in particular to bring the era of revolution, not only can easily carry, but also with any direction, greatly improving efficiency. 

 In modern times with the rise of the industrial revolution, more and more devices need to move, casters also more widely in the world, almost all walks of life without casters. With modern science and technology to the continuous development of increasingly multifunctional and high equipment utilization, casters become an indispensable part. Casters will be more professional development is made to a particular industry. 

 The application of castor 

 Caster is widely used, almost any design industry. According to the needs of different industries, people continue to invent all kinds of casters in the world there are about 150,000 kinds of different wheels used in various industries. 

 The structure by a single caster wheel mounted on the bracket is made for the installation of the equipment below to make it move freely. Casters can be divided into two categories: 

 A fixed mounting bracket coupled with a single wheel casters, can only move along a straight line. 

 B Caster bracket coupled with 360-degree turn to the single-round, is able to travel in any direction. 

 Industrial casters, single wheel variety, in size, type, tread, etc. vary. Select the appropriate wheel to take on the following conditions: 

 A carrying capacity. 

 B using the site environment 

 C a variety of special climate, such as humidity, heat or cold. 

 D work environment with chemicals, blood, grease, oil, salt and other substances. 

 E shock, impact and quiet driving requirements. 

 How you choose to use the caster 

 (Here are the main considerations) 

 First, how to choose the appropriate wheel 

 1, select the wheel material: first consider the use of road space the size of the obstacles, the use of residual material on the site (such as iron, oil), in which environmental conditions (such as high temperature, room temperature or cold) and the wheel can carry the weight of the different select the appropriate conditions to determine the wheel material. For example: rubber wheel can not be acid, oil and chemicals, super-polyurethane wheels, high-strength polyurethane wheels, nylon wheels, steel wheels and high-temperature wheel is able to apply different special circumstances. 

 2, calculate the load capacity: In order to calculate the load capacity of various casters need to be aware of transport equipment weight, maximum load and the wheels and casters with a single number. A single wheel or wheels required load capacity is calculated as follows: 

 T = (E + Z) / M × N: 

 --- T = single wheel or wheels need weight-bearing; 

 --- E = weight of transport equipment; 

 --- Z = maximum load; 

 --- M = the single number of wheels and casters; 

 --- N = safety factor (about 1.3-1.5). 

 3, decided to wheel diameter size: larger diameter wheels are usually more easy to push, the greater the load capacity but also better able to protect the floor from damage, wheel diameter size selection should first consider the weight and load carrying transport vehicles starting next thrust to decide. 

 4, the choice of wheels hard and soft materials: nylon wheels are usually round, super-polyurethane wheels, high-strength polyurethane wheels, high-strength synthetic rubber tire, Iron, cheer round. Super polyurethane wheels, high-strength polyurethane wheels on the ground both in indoor and outdoor running, you can meet the transportation requirements; high-strength synthetic rubber tire is able to apply to hotels, medical equipment, floors, wood floors, ceramic tile floors, etc. asked a quiet noise when walking on the ground running; nylon wheel, iron wheel for uneven ground or ground substances such as iron filings on the site; and cheer round is applicable to soft light load and road surface uneven occasions. 

 5, rotation flexibility: the greater the rotation the more labor-saving single-round, roller bearings can carry heavier loads, greater resistance to rotation: single wheel installation quality (bearing steel) ball bearing, can carry heavier loads , turning lighter, flexible quiet. 

 6, the temperature conditions: cold and hot places a great impact on casters, polyurethane wheels at low temperature under minus 45 ℃, rotating flexible and comfortable, high-temperature wheel rotating at a high temperature 275 ℃ under the light. 

 Cart Casters Casters Caster Company's plant, how to choose the appropriate wheel frame 

 1, usually select the appropriate caster wheel frame carrying the weight of the first consideration, such as supermarkets, schools, hospitals, office buildings, hotels and other places, because the floor well, smooth and light cargo transport, (bearing in each caster 10-140kg) suitable choice of thin steel plate (2-4mm) plating stamping wheel frame, the wheel frame light, flexible operation, quiet and beautiful, this ball arranged by plating wheel frame is divided into double and single row of pearl beads. If moving or carrying applications often double beads. 

 2, in places such as factories and warehouses, cargo handling is very frequent and heavy load (load per caster in the 280-420kg) is suitable for use with thick steel plate (5-6 mm) stamping Forging and welding of the double wheel ball frame. 

 3, if used to transport heavy objects such as textile factories, automobile factories, machinery and factories and other places, and the factory as a major charge to walk a long distance (per caster load in 350-1200kg), it should choose to thick steel plate (8-12mm ) cutting welding after the round frame, round activities, ball bearings and ball bearings with flat rack in the bottom, so that the caster can withstand heavy-duty, flexible rotation, anti-collision function. 

 Third, select the appropriate bearing 

 1, Patel spiritual bearings: Patel Ling is a special plastic, suitable for wet and corrosive areas, the flexibility of the general rotation, greater resistance. 

 2, roller bearings: heat-treated roller bearings can carry heavier loads, rotation flexibility in general. 

 3, ball bearings: high quality ball bearings made of bearing steel, can carry heavier loads, for applications that require flexible and quiet rotation occasions. 

 4, plane bearings: suitable for high and ultra-high load and high speed applications. Cart Casters Casters Caster Company Factory
