Structural Design

• European-Style Bracket: Made of thickened cold-rolled steel plate (typically ≥3mm), stamped and welded for a compact structure with superior load capacity. The surface is galvanized/chrome-plated for strong corrosion resistance.
• Dual Brake System: Features both wheel brake and swivel brake (dual brake model). When engaged, it locks the wheel rotation and the bracket swivel simultaneously, preventing sliding or accidental movement — far safer than single-brake casters.
• Iron Core Polyurethane Wheel: The wheel body has a cast iron hub (iron core) inside, wrapped with high-elasticity polyurethane on the outside. It offers high load capacity (typically ≥300kg per caster) and excellent wear resistance, while being floor-friendly and operating at noise levels below 50dB.
• Swivel Structure: Equipped with double-row ball bearings or plane bearings for smooth 360° rotation, ensuring easy maneuverability even under heavy loads.

Material Performance

• Polyurethane Tread: Abrasion resistance coefficient of 0.5–0.8 (superior to ordinary rubber), strong tear resistance, suitable for both indoor and outdoor floors (e.g., concrete, epoxy flooring). Operating temperature range: -30°C to 80°C, adaptable to various climates.
• Reinforced Bracket: The bracket and swivel structure are reinforced with rivets or bolts, offering strong impact resistance to withstand frequent collisions or heavy impacts.

Dual Brake Safety

• Compared to ordinary single-brake casters (which only lock the wheel), the dual brake system locks both the wheel and the swivel, completely eliminating the risk of sliding or turning — ideal for slopes, uneven ground, and scenarios requiring precise positioning.
• The brake spring plate and pedal linkage design ensures no loosening after locking, with anti-slip failure risk 80% lower than the industry average.

High Load Capacity & Long Service Life

• The iron core structure enhances overall wheel strength, with dynamic load capacity reaching 400–800kg (for 6–8 inch sizes) and static load exceeding 1200kg. Service life is 1.5 times longer than ordinary rubber wheels.
• The polyurethane tread is wear-resistant and chemically resistant (oil, weak acids, and alkalis), suitable for harsh environments like factories and warehouses.

Flexible Adaptability

• The swivel structure with precision bearings enables small-radius turning (e.g., 6-inch caster swivel radius ≈120mm), making operation easy in tight spaces.
• Standardized mounting hole spacing (e.g., bolt hole diameter 13mm) ensures compatibility with most scaffolding and equipment bases.
