With the explosive growth of the global e-commerce industry, "small-volume, high-frequency, and ultra-fast delivery" has become the standard for order fulfillment. Driven by this trend, high-speed, lightweight Mini-Load stacker cranes have emerged as the "star performers" of modern automated logistics centers.
These machines demand not only high travel speeds but also extreme acceleration and high-frequency start-stop cycles. Behind this peak performance lies a critical component that bears the brunt of the kinetic energy: the stacker crane wheel, which is now facing unprecedented technical challenges.
1. Industry Status: Why do Automated Stacker Cranes Require Stronger Wheels?
In high-speed operations, a stacker crane wheel does much more than just "roll." Every acceleration and emergency stop generates intense impact forces and frictional heat. Improper material selection can lead to severe consequences:
Internal Heat Build-up: Standard materials have poor heat dissipation. Heat accumulated during high-speed rotation can cause the tread to soften or even de-bond from the hub.
Flat Spot Deformation: When a stacker crane is stationary, prolonged pressure on a single point can cause permanent deformation (flat spots), leading to violent vibrations upon restarting.
High Maintenance Costs: Frequent wheel replacements incur not only material costs but also massive production losses due to equipment downtime.
2. NDI Polyurethane:
To meet these challenges, NDI based polyurethane has become the globally recognized material of choice for high-end stacker cranes.
Thanks to its unique molecular structure, NDI material exhibits unparalleled physical properties:
Superior Dynamic Load Capacity: It maintains extremely low temperature rise during high-speed operation, fundamentally solving the problem of wheel failure due to heat.
Exceptional Compression Resistance: With high dynamic resilience, it quickly recovers its shape even after bearing heavy loads for long periods, effectively preventing "flat spots."
Ultra-Low Rolling Resistance: This reduces the energy consumption of the crane’s motors, contributing to green logistics.
Within the NDI family, Vulkollan® stands as the premier representative and is widely utilized across the globe. It represents the pinnacle of polyurethane elastomer technology, ensuring the stable operation of ultra-high and heavy-duty stacker crane systems.
