The cost of tyres represents a significant proportion in the use of large working machines. By using tyre protection chains, we protect tyres from damage and extend their lifetime even by 40–50 %.
In addition to protection, chains also offer improved grip and reduce the possibility of the wheels slipping. Depending on the different types of protection elements, the grip also varies from element to element.
Protection chains increase the surface of the wheel, which is in contact with the ground, which increases the stability of the machine. They also prevent the wheels from slipping on smooth surfaces and provide greater stability (also side stability) on slopes.
The choice of material is very important in addition to the construction of the chain. The material must be suitable for heat treatment and contain the correct ratio of carbon and other alloying elements, which allow for high-quality heat treatment and thus a high degree of hardness, which ensures a long lifetime of the chain.
The lifespan of protection chains depends on the correct heat treatment of the elements. The hardness on the surface has a high value, which decreases with depth, however. Adequate hardness in the core provides the toughness of material, which is important for heavy loads and chain endurance.
The desired chain properties are ensured by the carburising process.
Effects on chain life:
Depending on the conditions in which the protection chains are used, we guarantee the following number of working hours:
|Type of rock||Hardness||Working hours|
|Granite, Quarz, Porphyr|
