How to select the right scaffold caster wheels

When working on a scaffold, it is essential to ensure maximum safety. Often, when using mobile scaffolds, people overlook the importance of a good set of wheels. As many scaffolding caster wheels are available in the market, it is necessary to select the right one. Here are some of the factors to consider while purchasing scaffolding caster wheels 

1. Wheel Diameter 

Scaffold caster wheels with diameter 130mm are applicable when undertaking simple scaffolding tasks. These small scaffolding caster wheels have a locking system that secures it to the scaffold; however, these caster wheels cannot be adjusted. Since small scaffold caster wheels are not designed for large or tall mobile scaffolds, it cannot deal with debris or variations in surface conditions. Therefore, the chances of instability are high with small scaffold caster wheels. If the scaffolding is heavier and taller, installing caster wheels of 200mm would be the right choice. It has to ability to move through rough surfaces and ensure maximum safety. It is also necessary to ensure that the selected scaffolding caster wheels have an easy and robust brake mechanism. 

2. Safe Working Load (SWL)  

Mobile scaffolds need to be tested for its safe working load. This information is critical as light-duty scaffolds generally require five-inch (130mm) caster wheels, whereas medium duty scaffolds require eight-inch (200mm) caster wheels.  

3. Tube Compatibility  

Every mobile scaffold wheel is designed to fit a specific tube diameter. Therefore, checking the tube diameter is an essential factor to consider while purchasing scaffolding caster wheels. If the chosen caster wheels do not fit, it can cause cracking and instability of mobile scaffolds. 

4. Adjustment Shaft 

A scaffold wheel is designed with a thread and nut to provide vertical adjustment. When purchasing scaffolding caster wheels, it is necessary to understand the adjustment limit and shaft length. This is because, some caster wheels are designed with a shaft that is threaded for its entire length, whereas other caster wheels are limited to two-thirds of shaft length. Experts states, to ensure maximum safety, mobile scaffolds should not operate with more than two-third of shaft length outside the frame, and it also recommends not using more than half of the shaft length. 

5. Wheel Covering 

Commonly, rubber and polyurethane are found in the market. Rubber is used for small scaffold caster wheels, and polyurethane is common among the larger sizes.
