Abstract The brake system of the crane is one of the main systems responsible for its safety. Due to the presence of a number of factors, such as unequal braking force of the brake spring, uneven wearout of the brake pads, and the presence of pollutants, the friction force is variable and varies widely. As a consequence, there is a different braking torque on the drive wheels of the crane. It leads to the skidding of one of the sides of the crane, the spreading of the drive wheels with the emphasis of the flanges on the crane rail and the skewing of the entire metal structure. There are additional loads in the metal, which reduces the reliability of the crane in the work. The principle of stabilization of braking forces by differential mechanisms on the crane wheels is being developed. The proposed solution provides the same braking force on the wheels with different modes of braking the crane. The kinematic scheme is based on the principle of distribution of power flows between the hydraulic differential, installed on the carts. The design of the hydraulic brake system of the crane is considered. A mathematical model of the differential brake system of a crane and the results of its computer simulation in the Mathcad environment are given. According to the results of mathematical analysis, the parameters of the brake system are determined.
