Heavy Duty Vulkollan Monorail Drive Wheels & High Grip Transport Wheels are engineered with genuine Vulkollan NDI polyurethane treads, integrally vulcanized and bonded to steel/cast iron hubs. Designed specifically for monorail cranes, overhead cranes, AGVs (Automated Guided Vehicles), heavy-duty logistics transportation, and industrial rail-mounted equipment, these wheels offer superior advantages including high load capacity, excellent grip, wear and tear resistance, low noise, oil and weather resistance, and non-delamination. Under heavy-duty working conditions, their service life is far longer than that of ordinary PU, rubber, and nylon wheels.

2. General Parameters of High Grip Transport Wheels
• Outer Diameter Range: 100mm～600mm (Non-standard customization available)
• Tread Width Range: 50mm～200mm
• Inner Hole Specification: 20～90mm, can be processed into round holes, keyways, and set screws
• Standard Hardness: 92A (High anti-slip type); 85A (Shock absorption and mute type); 95A (Ultra-high wear-resistant and heavy-duty type)
• Travel Speed: Regular ≤16km/h, can operate continuously for a long time under low-speed and heavy-load conditions
• Climbing Capacity: Adaptable to monorail inclination angle ≤30°, no slipping or sliding
Mechanical Performance Parameters
1. Rolling Resistance: 25%～35% lower than rubber wheels, energy-saving and power-saving, with smaller driving load
2. Shock Absorption and Noise Reduction: Operating noise ≤65dB, buffering and shock absorption, reducing impact wear of equipment and rails
3. Impact Resistance: Can withstand instantaneous impact load of 1.5 times the rated dynamic load, not easy to edge chipping or cracking
4. Wear Life: Can be used for 2～5 years under continuous working conditions, no frequent replacement and maintenance required
5. Operating Mode: Supports continuous operation, intermittent operation, and high-frequency start-stop working conditions
Adaptable Working Conditions & Installation Parameters
• Adaptable Rails: I-beam monorail, H-beam rail, flat steel rail, concrete flat ground
• Bearing Configuration: Pre-installable double-sealed deep groove ball bearings / self-aligning roller bearings, dust-proof and waterproof
• Installation Methods: Three options available: interference fit, keyway transmission, and set screw fixation
• Customization Service: Can modify outer diameter, width, inner hole, hardness, hub structure, and color
Application Scenarios
Monorail overhead cranes, bridge cranes, automated warehouse stackers, AGV automated guided vehicles, heavy-duty logistics trolleys, port terminal transfer equipment, mining conveyor machinery, and heavy-duty assembly line conveyor systems in workshops.
