HOW IT WORKS

High Strain Ductile Steel: The inner wheel and outer tire structures are made from high-performance ductile steel which both have been welded and bolted together to withstand extreme conditions.

High Performance Nitrogen Cylinders: The nitrogen cylinders interconnecting the rim and drum have bidirectional movement and have a rated pressure of 2,500 PSI and a burst pressure of 10,000 PSI. The cylinders are hermetically sealed against mud, dust, rocks, and water. Additionally, the cylinders have internal lubrication and are sealed with high-performance elastomeric seals.

Solid Polyurethane or Steel Treaded Shoes: The solid treaded shoes are designed to last three to five times longer than OTR tires. They do not overheat and there is little deformation, moreover, there is no sensitivity to uneven tread wear. The ASWs can be outfitted with PU treaded shoes with a hardness range from Duro A55 to D85. Fire retardant treaded shoes are also available.

ASWs can be designed to handle higher payload capacity than rubber. Load differences also do not affect performance.

ASWs have high lateral stability and only only have a marginal deformation. They are designed to cope with more lateral side load, making them more stable (less risk of truck tilting) and safer than rubber tires in sharp corners. They also have better traction and reduced skidding risk.

ASWs can save fuel because the hub leads the wheel, the he cylinders store braking energy, and the smaller ground contact area of ASWs reduces rolling resistance.

Rubber tires often represent a hug safety hazard for drivers and maintenance crews at mines because they can explode or catch fire due to overheating, improper inflation or installation or lightning strikers. When explosions do occur, they are often fatal with blast areas up to 400 meters.

ASWs cannot explode or overheat, making them safer for workers. With ASWs you do not longer need to deal with overheating, risk of fire and explosions, and tire changes in dangerous situations.

The ASW eliminates precious downtime due to rubber tire failures or tires changes.

Tires are the mining industry's largest expense after payroll. Rapid wear and tear caused by impact, rock cuts, and extreme and uneven loading means the lifespan of an expensive mining tire is short. Mining companies are forced to use 'Band-Aid' solutions such as patch up repairs, tire pressure monitoring, tire retreading, tire cooling systems, and tire rotation to extend the tire's useful life. One (1) 13,000 lb. OTR mining tire can cost over $75,000 and only lasts six to nine months. That is a large expense for a product that does not last.

ASWs reduce costs because rubber OTR mining tires have to be replaced every six to nine months while ASWs last as long as the vehicle.

ASWs require minimal maintenance and are designed to last as long as the vehicle does.
ASWs are self-aligning and self-balancing. Wheel rotation is not necessary and they do not have rim corrosion. The cylinders need a yearly check and the seals are designed to last three years. The air cylinders are designed to last ten years, and the wheel’s mud seal is designed to last four years.
The bolt-on polyurethane treaded shoes are individually mounted and are easily replaced during a fuel stop. The individual treads can be replaced without removing the wheel, a lengthy process that takes up to eight (8) hours with a rubber tire.

The ASW functions as a flexible torque coupler, reducing stress & strain on axel, transmission and engine.

Additionally with ASWs you don’t longer need deal with rubber tire related issue like tyre management, compressed air or other gases (e.g. nitrogen), heat or fire or risks, chemicals, TPMS, tire storage, tire scrapping, tire rotation, and offsite tire repairs.

ASWs can completely be customized based on your specific requirements for payload and strains. Larger than R63 wheels are possible. Thread hardness shore A55 up to D85. Fire retardant can be added to the threads.
