[0002] Nowadays, most common crane load-bearing pads in life are sleepers, but sleepers are not suitable for use on muddy ground. Wet soil can easily make the sleepers damp, thereby reducing their service life. Therefore, when sleepers are used on muddy roads, they need to be wrapped with waterproof cloth on the outside to prevent the sleepers from direct contact with mud and water. However, this will cause the crane to be unable to quickly enter the working state on the muddy road. In response to the above situation, technical innovation is carried out based on the existing crane load-bearing support leg pads. Utility Model Content
