The supporting wheel is made of high-quality materials and advanced technology, with high surface hardness and good wear-resistant performance, which can adapt to the complex working environment. It is easy to install and can match perfectly with the chassis of Caterpillar E70 series excavators to ensure the stable operation of the excavators.
