The following is a detailed introduction to scaffolding wheels:
Function
Easy to move: installed at the bottom of the scaffolding, the sliding friction between the scaffolding and the ground is converted into rolling friction, which greatly reduces the resistance during movement, allowing the scaffolding to be easily moved and adjusted on the construction site, improving construction efficiency.
Load-bearing weight: bear the weight of the scaffolding itself and the staff, tools, materials, etc. on the scaffolding, ensuring the stability and safety of the scaffolding under various construction conditions.
Adjusting height and level: Some scaffolding wheels are equipped with adjustable screws, which can be used to adjust the height and level of the scaffolding to adapt to different construction sites and operation requirements.
Structural components
Hub: It is the main supporting structure of the wheel, usually made of high-quality cast iron or cast steel, with high strength and wear resistance, and can withstand the weight of the scaffolding and the impact force during operation.

Bearing: installed inside the hub, generally using precision rolling bearings, its function is to ensure that the wheel rotates flexibly, reduce friction and wear, and make the scaffolding move more smoothly.
Wheel bearings for construction scaffolding
Tires: directly in contact with the ground, rubber, polyurethane or nylon can be selected according to the use environment. Rubber tires have good elasticity and anti-skid properties and are suitable for various ground surfaces; polyurethane tires have good wear resistance and high hardness, and are suitable for flat hard ground surfaces; nylon tires have high strength and corrosion resistance.

Brake device: used to fix the position of the scaffolding to prevent it from accidentally sliding when it does not need to be moved. Common brake devices include foot brakes and hand brakes, which keep the scaffolding stable by braking the wheels or hubs.

Type
Steer wheel: also called fixed wheel, cannot rotate 360 degrees, can only move forward or backward in a straight line, usually installed at the front or rear end of the scaffolding, playing a guiding and stabilizing role.

Universal wheel: can rotate 360 degrees freely, so that the scaffolding can change direction flexibly, and is easy to move in small spaces or complex terrains. It is generally installed on the side or corner of the scaffolding.

Selection method
Load-bearing capacity: According to the maximum load-bearing weight of the scaffolding, choose a wheel that can bear the corresponding load. Generally, the manufacturer will indicate the load-bearing range of the wheel in the product specifications to ensure that the wheel will not be damaged due to overload during use.
Material: Choose the appropriate wheel material according to the construction environment. For example, in a humid environment, iron wheels should be avoided. Aluminum alloy or stainless steel wheels can be used to prevent rust; in a high temperature environment, high temperature resistant materials need to be selected.
Size: The size of the wheel should match the height, weight and usage scenario of the scaffolding. Larger wheels usually have better passability and load-bearing capacity, but they will also increase the overall height and weight of the scaffolding. Common scaffolding wheel sizes are 4 inches, 5 inches, 6 inches and 8 inches.
Brake function: If the construction site requires the scaffolding to be frequently fixed in a specific position, then a wheel with a reliable brake device is essential. When choosing, pay attention to the sensitivity and reliability of the brake to ensure that the scaffolding will not slide when fixed.
