These giant tires are usually used on the open-pit mining sites.
What is a open-pit mining site?
Open-pit mining, also known as opencast mining, is a surface mining technique that extracts minerals from an open pit in the ground. Open-pit mining is the most common method used throughout the world for mineral mining. This surface mining technique is used when mineral or ore deposits are found relatively close to the surface of the earth. Open-pits are sometimes called ‘quarries’ when they produce building materials and dimension stone.
Materials commonly extracted from open-pit mines include:
Bitumen Clay Coal Copper Coquina Diamonds Iron
Gold Gravel and Bedrock Granite Gritstone Gypsum
Limestone Marble Molybdenum Silver Uranium Phosphate
Contrary to Open pit mining, is the undergroud mining.
Underground mining is the process of extracting minerals, rocks and other industrial materials other than oil, coal and gas from the earth through the development of shafts and entries from the surface to the deposits or seam before recovering the products and using underground extraction methods.
Precisely defined methods must be used when handling the tires. Failure to use these methods may cause irreparable damage to tires and may even be dangerous. The bead is a sensitive part of the tire, and if it is damaged during handling operations, this may lead to premature scrapping of the tire.
To limit the risks:
Tires should preferably be handled using the appropriate equipment for this type of work: forklift truck, mechanical loader or crane equipped with a tire handler or textile straps; lift the tire by the tread.
If there is no other option than to lift and handle the tire by the beads, the following must be used:
