A car crusher is a machine designed to compress and flatten old vehicles, making them easier to transport and recycle. It uses powerful hydraulic systems to apply immense pressure, reducing the size of the car significantly. This process helps in reclaiming valuable materials like metal, which can be reused in manufacturing new products. Car crushers are commonly found in junkyards and recycling facilities. They play a crucial role in the automotive recycling industry by ensuring that discarded vehicles are processed efficiently. By crushing cars, these machines help reduce waste and promote environmental sustainability through the recycling of materials like steel and aluminum.
