Casters used in single mast aluminum lifts (such as personnel lifts, vertical mast lifts, or aerial work platforms) need to be durable, provide good maneuverability, and withstand the weight of the lift and operator. The materials used for these casters typically fall into the following categories:
Common Caster Wheel Materials
1.Polyurethane (PU)
Features: Durable, non-marking, abrasion-resistant, quiet.
Pros: Good for both indoor and outdoor use; protects floors.
Use Case: Frequently used in personnel lifts operating on finished floors.
2.Rubber
Features: Soft ride, quiet, absorbs shock.
Pros: Good traction, safe on delicate surfaces.
Cons: Wears faster under heavy loads.
Use Case: Light-duty lifts on smooth indoor floors.
3.Nylon
Features: Hard, impact-resistant, low rolling resistance.
Pros: Resistant to many chemicals; durable under heavy loads.
Cons: Noisy on hard floors; can mark softer surfaces.
Use Case: Industrial environments where floor protection is not critical.
4.Phenolic Resin
Features: Hard composite material, heat-resistant.
Pros: Can carry heavy loads; economical.
Cons: Can damage floors; noisy.
Use Case: Heavy-duty applications where floor damage isn't a concern.
5.Steel or Cast Iron
Features: Very strong, high load capacity.
Pros: Ideal for rough surfaces or extreme loads.
Cons: Extremely noisy, damages flooring, no shock absorption.
Use Case: Rare in aluminum mast lifts, but used in rugged industrial settings.
Caster Frame and Hardware Materials
1.Zinc-Plated Steel
Most common frame material for corrosion resistance.
2.Stainless Steel
Used in harsh environments or where rust resistance is critical.
3.Aluminum
Rare for caster frames, but sometimes used to match the lift frame's lightweight design.
Additional Caster Features for Aluminum Lifts
Swivel with Lock: For directional control and safety.
Brake Mechanism: Often a foot-activated brake to keep the lift stationary.
Non-Marking Wheels: Critical in commercial or finished floor environments.
