Features of operation of STA-5TM replaceable technological superstructure for application of solid mineral fertilizers based on Ural-432065 vehicle chassis

Abstract

The development of Ural-432065 specialized all-wheel vehicle chassis with STA-5TM replaceable technological superstructure for application of solid mineral fertilizers complies with the agrotechnical, safe operation and maintenance requirements. Safety requirements and warning descriptions are reflected in the service manual in both text and graphical forms. It is important to study this manual before starting. The relevant symbols are represented on the equipment in locations of working organs and servo units. The Ural-432065 chassis with STA-5TM replaceable technological superstructure is intended for agricultural and municipal works, such as application of dry granulated fertilizers and spreading of earth-moist lime, sand, broken stone, salt and mixtures. General view of the STA-5TM superstructure, its specification, composition, principle of operation, operator control, hydraulic circuit description, electrical schematic diagram, features of operation and service are presented. Amount of fertilizer is controlled by the principal slide gate. Under transportation mode, the slide gate should be occluded. Distribution of granular fertilizers is carried out by the spreading discs. Distributing width is 10-36 m. The adjustment is made on the basis of table of application rate or by means of passing of measuring distance, taking into account the grain size, volume weight, surface structure and moisture. Operation of the STA-5TM replaceable technological superstructure for application of solid mineral fertilizers based on Ural-432065 vehicle chassis is provided by the performance and technology standards, regulated by relevant documents, available and handy to the operator. Design capabilities and used constituent parts allow to increase the operating efficiency as a part of technological complexes with rise in labor productivity.
