With the development of industrial technology, lifting equipment has been widely used in various industries. Among them, truck cranes are often chosen in daily use due to their good mobility and rapid transfer. The slewing bearing is an important component in a truck crane that connects the upper and lower parts of the vehicle. Taking a certain model of truck crane as an example, this paper analyzes the contact stress of its slewing bearing by using two methods: Hertz contact theory and finite element method. It also explores the influence of the main structural parameters of the slewing bearing on the contact stress, so as to provide a reference for product selection and design.
