Imagine: You want to paint a high wall and need scaffolding to do so. However, your scaffolding does not have castors, and you always need at least one other person to move it.
Conclusion: Mobile scaffolding and ladders are indispensable in trade and industry. They are flexible to handle yet stable in use.
Unlike other castors, scaffolding castors focus on static rather than dynamic load capacity. Mobile work platforms and rolling scaffolds are subject to their own testing standard, which is primarily aimed at increasing occupational safety during use.
