Hinged aggregate for technical maintenance of machines: Modeling, testing and conditions of application

The article shows the relevance of the availability of mobile service tools for maintenance of machines in the conditions of agricultural enterprises. The main purpose of the work is to simulate, test and describe the application conditions of the hinged unit for maintenance of machines. Improvement of maintenance units should be carried out in the direction of improving their environmental safety and reducing costs. The authors offer a small-sized maintenance aggregate, substantiate its functionality, hinged type of execution, the layout algorithm and the condition of economic feasibility of purchasing this service unit by the enterprise. The test results of the experimental unit prove that it satisfies the requirements of safety and ergonomics, while the laboriousness of service works does not exceed the current normative values. Technical and economic calculation shows a reduction in the cost of service operations relative to serial analogues and the expediency of using the aggregate in the conditions of agricultural enterprises of all organizational forms.
