Heavy Duty Caster


Heavy-duty casters refers to the caster wheel load capacity is bigger, is, according to the caster wheel bearing capacity is relatively light castor, medium casters, classify, and no clear boundaries, generally from 500 kg to 15 tons, even higher load castor, called heavy-duty casters.


Design

Bracket design for heavy casters.

The bracket of heavy-duty casters usually adopts metal material as the main body, including ordinary steel plate punching and forming, casting steel forming, die forging steel forming, etc., usually mainly plate type assembly. The steel plate thickness of heavy casters is usually 8mm, 10mm,16mm and 20mm steel. At present, wanda is carrying 12 tons of special heavy-duty casters designed for China's petroleum system, with 30mm thick steel plate and 40mm supporting plate, which effectively guarantees the safety of the product.

Rotary plate design for heavy duty wheel.

The heavy-duty casters are usually made of double-layer steel ball, stamping and heat treatment. For the rotary plate of the special heavy duty wheel, it is generally used to have a larger planar ball bearing or plain roller bearing, and a matching cone bearing, which effectively improves the load capacity of the heavy casters. For the special anti-impact heavy duty wheel, the rotary plate adopts die forging steel, finishing and forming, effectively avoiding the welding of the connecting plate bolt, and improving the impact resistance of the caster.


Choose

Wheel material selection for heavy casters.

Heavy casters are used for heavy equipment movement, so the wheels of heavy-duty casters are usually made with a single wheel of hard tread. Such as nylon wheel, cast iron wheel, forged steel wheel, hard rubber wheel, polyurethane wheel, and phenolic resin wheel are ideal. The forging steel wheel and polyurethane casters are especially suitable for the wheels with special heavy-duty casters.

Wheel diameter selection of heavy casters.

According to the diameter of the wheel, the greater the rotation of the more flexible principle of commonly used specifications are 4 inches castor, castor 5 inches and 6 inches castor, 8 inches castor, 10 inches castor, 12 inches castor, track, caster can use 16 inches and 18 inches of the wheel. At present, we produce 12 tons of special heavy-duty casters with a diameter of 400mm and a wheel width of 125mm. Of course, you can also customize the heavy duty of special specifications, for example, the low-gravity heavy-duty casters, the smallest 2-inch casters, or the weight of more than 360kg.

Selection of heavy-duty caster manufacturers.

At present, the domestic production of castor manufacturers a lot, good and bad are intermingled, so, the user should have to choose heavy duty castor manufacturers, and can not blindly pursue low price, in order to avoid because of the reason of castor, causes the damage of the product loaded, cause unnecessary damage to property. Select professional heavy-duty caster manufacturers, users can refer to the following points:

1. Regular heavy caster manufacturers, generally able to provide the drawing and other necessary technical parameters;

2. The normal heavy-duty caster should have professional testing equipment, including foot wheel walking test, load test and other professional foot wheel detection equipment. Otherwise, it is impossible to judge the load requirements of the caster.
