In this article the object of research is the bulldozer. The subject of the research is the longevity of the dozer. The urgency of the problem due to the high demand for the use of bulldozers, which entails a high financial costs for the restoration of this machine. The article sets the task of analysis the changes in the design of the working equipment of the bulldozer, also examines the impact of application of different components of the longevity of the dozer. The purpose of this study is to investigate the strengths and weaknesses in the equipment, finding different ways to improve the durability of bulldozers, to study of the constructive features of the machine. Design and operational features of the bulldozers were identified.. The factors of external environment that have a negative impact on the operation of the machine were identified too. Different schemes of hydraulic equipment, bulldozers and the main structural elements, principles of their working were explained. The differences, the strengths and weaknesses of all considered design solutions were identified and justified. By using such devices as: compensation cylinders comprising a hydraulic drive, a vertical elastic connection between the car and the equipment, isolation of flexible hoses connected to the hydraulic drive, a Ripper tooth and the crank is achieved the increased longevity of the bulldozers. It justifies expediency of use of the hydraulic drive, in particular hydraulic cylinders for controlling the position of the blade. As a result of the study revealed the best device that allows increasing the longevity of the dozer. The durability of the device is achieved by means of hydraulic cylinders-the sensor and compensating cylinders. It should also be noted that in theinvention, using the accumulator of stored energy can reduce the costs of energy required for the operation of the bulldozer.
