First, size

Generally the greater the diameter of the casters, the more effort to promote, the more obstacles the better. Casters generally in inches to represent, most of China's supermarket trolley is 4-inch, 5-inch casters. Currently on the market popular casters from 1 inch to 10 inches range, commonly used size

2 inch, 3 inch, 3 inch, 3.5 inch, 4 inch, 5 inch, 6 inch, 8 inch, 10 inch, etc. Generally have to promote, such as supermarket shopping carts, trolleys, logistics trolleys, 6 inch casters better. The diameter of the casters is too large to raise the center of gravity

This increase, so need to be considered. If the equipment does not need to often promote, such as furniture, refrigerators, etc., choose 3-inch casters can be.

Second, load-bearing

The same diameter of the casters, there will be several different load-bearing series, such as light, medium, heavy, so that wheels and brackets have different thickness or material. The load of a single casters to give a certain degree of insurance in the relatively flat ground. single

If the ground is not flat, then the algorithm is a single casters load = total weight ÷ 3, because no matter what kind of non-flat ground, always at least on the basis of the total weight of the equipment, There are three wheels that simultaneously support the device

The algorithm is equal to the increase in the insurance factor, more reliable, to prevent underweight, resulting in greatly reduced or lead to the cause of the accident. In foreign companies, the load is generally expressed in pounds, while the domestic most of the kilograms, they conversion relationship is: 2.2 pounds = 1 kg.

Third, the casters material

Generally have PU, TPR, PP, rubber, nylon, etc., as for the temperature, surface hardness, the ground environment

Fourth, the installation: the general light load available screw, plunger, expansion sleeve, etc., heavy load with the floor, or directly welded to the device. General large companies are installed in a very rich way.

Fifth, the brake: from the function, there are brake wheels, there are brakes universal, both with the brake was double brake, there are tread brake, the moment brake, side brake, etc., specifically contact the casters factory.

Six, casters on the equipment layout

1. Triangle support, 3 caster.

3 rounds into a triangular shape, this arrangement is more suitable for barrel or small equipment handling, with good sports performance, and triangular support is a kind of economic and stable arrangement, flexibility is stronger than the four universal Round, stability and not lose four caster, for small equipment is an excellent choice for short distance handling.

2. Triangular support, one caster, two directional wheels.

1 caster in front, two directional wheels in the rear, this arrangement is more suitable for light equipment and suitable for low center of gravity equipment, and the direction of easy control, but also a stable and economical way, suitable for short distance handling.

3. Assemble 2 directional wheels, 2 casters.

There are two ways of arrangement, one is: two caster in front, two directional wheels in the post. This is a very conventional arrangement, most of the equipment are arranged in this way the caster, with excellent direction control, suitable for long-distance use, and have a certain load-bearing capacity.

The other arrangement is arranged in a diamond-shaped arrangement, one caster in front, two directional wheels in the middle, one after the caster. This arrangement is very easy to move forward and backward, climbing capacity of some lack of a certain load-bearing capacity.

4. Diamond arrangement, equipped with four directional wheels.

The same rhombic arrangement, but the diamond from the directional wheel composition, from this design can be seen that the turn is not allowed, this design is designed for straight-line design, can carry heavy equipment, can be a long distance handling, It is not possible to travel on a sloping ground.

5. Rectangular support, equipped with four casters

The caster is shaped like a heavy-duty equipment for handling in a narrow range, suitable for short-distance handling, suitable for a certain slope of the ground driving.

6. Rectangular support, equipped with four caster wheels and two directional wheels

Arranged in two casters in front of two casters in the rear, two directional wheels in the middle, this arrangement using six casters, from the number can be seen on its excellent carrying capacity, plus Before and after the caster, in the steering ability is also extremely excellent for heavy equipment long distance handling, in the uneven ground can also be stable forward.

Seven, stent selection: divided into directional and universal, the material generally with carbon steel, can be a variety of electroplating, such as galvanized, copper, nickel, chrome, spray, etc., but also useful stainless steel,

Eight, choose the caster brand: the world point of view, the forefront of market share is the United States Kexun Group (including Ke Shun colson, Jia Wei jarvis, Austrian Ben albion more than 10 brands), Germany Teng Teng tente, the two Brand to do more comprehensive, excellent quality performance, the production of a long history of the casters for the world's leading casters, most of the vast majority of small factories to imitate the company's products. Most of the other brands around the market to do, such as Wo to do more well-known metal wheels, and Shandong area is good at making a pneumatic wheel, the world to do more shopping cart casters, there are some professional medical. Of course, the brand quality is good, the price is more expensive.
