Features:- Designed for the most punishing environments on earth, these PU wheel chocks offer an unparalleled weight capacity of 396,800 lbs (180 Tons). This is the ultimate safety solution for large-scale mining trucks, quarry equipment, and heavy-duty dump trucks where failure is not an option.- With dimensions of 14 9/16" H x 17 5/16" L x 14 9/16" W, these chocks are specifically built to secure oversized tires (Outer Diameter approx. 58" / 1480mm). The steep, tall angle provides maximum stopping leverage for heavy loaders and industrial haulers.- Crafted from high-density, engineering-grade PU, these chocks are significantly more durable than rubber and won't rot, crack, or peel. At 19.5 lbs (8.85 kg), they provide high-mass stability while remaining manageable for site operators to position manually using the integrated handle.- The surface features reinforced horizontal traction ribs that lock into large tire treads, preventing any movement on steep quarry grades, loose gravel, or muddy construction sites. The bottom is engineered to grip the ground surface, ensuring zero-slip performance under immense pressure.Specifications:- Suitable Tire Diameter: approximately 58"- Dimensions: 17 5/16" x 14 9/16" x 14 9/16"- Load Bearing Capacity: 180 Ton- Suitable Vehicles: Mining Vehicles, Giant Loaders & ExcavatorsPackage Contents:- 1x Wheel Chock ( 1 Pair)- 1x Manual
