[0002] Crane is a material handling machinery, a multi-action lifting machinery that vertically lifts and horizontally transports heavy objects within a certain range. It is also called overhead crane, overhead crane, and crane. The main feature of a tire crane is that its driving cab and lifting control room are combined into one. It is evolved from a crawler crane, and the crawler and traveling bracket parts of the walking mechanism are turned into a chassis with tires, overcoming the shortcoming of crawler crane track plates causing damage to the road surface. It is a material handling machinery, and a support device is required during the use of the crane.
