The solution to the serious transport problems of lifting, fixing and lowering cargo, hull elements, scaffolding during construction and installation works performed by screw jacks at shipbuilding and ship repair enterprises, in ship docks is considered. Such disadvantages of hydraulic jacks as the inability to work at low and ultra-low temperatures, constant monitoring of the oil level, the tightness of oil seals and valves, transportation and storage only in an upright position, low operability, as well as the disadvantages of screw jacks such as the low starting torque of an asynchronous electric drive motor with the cylindrical stator bore, the lack of the ability to accurately position the load at height, led to the development of a hoist design which is characterized by increased carrying capacity, achieved by an additional increase in the torque transmitted to the nut of the structurally integrated electric drive of jack. Increasing the lifting capacity of the jack due to the built-in two-stage transmission, which reduces the rotation frequency, but at the same time increases the torque transmitted from the rotor to the nut, is researched. The ability to accurately fix the load at a height commensurate with the height of the prefabricated motor housing is achieved through an integrated braking device, which is activated after the supply voltage of the drive axial asynchronous electric motor is disconnected. This design will allow smooth lifting and lowering the load with its increased carrying capacity and precise fixation of the actuator, which allows to use it for multi-tiered construction of retractable closures, during inspection, repair, installation works and centering the assembly units of ships, as well as carry out work on lifting and lowering transshipment equipment in the port sector without using the additional expensive mounting equipment.The developed calculation methods allow at the design stage to determine the stock of its carrying capacity and the dependence of the jack efficiency on the parameters of a two-stage transmission.

В данной статье описываются виды и методы использования цифровых технологий при обучениидетей с ОВЗ в начальной школе. Так же приведены примеры использования этих технологий. Во всеммире возросло использование новых технологий в системе образования. Наряду с развитием технологийу детей этого века есть различные способы взаимодействия для обучения, слушания, интерпретации имышления. Информационные технологии оказывают положительное влияние на образовательныйконтекст. В образовательной политике России признается важность информационных технологий впроцессе обучения и преподавания в школах. В этой статье описывается эффективность цифровогорассказывания историй в сравнении с традиционным и цифровым процессом обучения учащихсяначальных школ. Интеграции детей с нарушениями психофизического развития в общеобразовательноепространство РФ как одно из направлений гуманизации всей системы образования, соответствуетприоритетам современной государственной политики. В России правительство пытается сделать вседля того, чтобы догнать по показателям инклюзии европейские страны. Для успешного обучения детейс особенностями психофизического развития, инклюзивная школа реализует программу психолого-педагогического сопровождения с привлечением квалифицированных логопедов, дефектологов,психологов, социальных педагогов, ассистентов учителей и других специалистов. This article describes the types and methods of using digital technologies in teaching children withdisabilities in primary school. Examples of the use of these technologies are also given. The use of newtechnologies in the education system has increased all over the world. Along with the development oftechnology, children of this century have various ways of interacting for learning, listening, interpreting andthinking. Information technologies have a positive impact on the educational context. The educational policy ofRussia recognizes the importance of information technology in the process of learning and teaching in schools.This article describes the effectiveness of digital storytelling in comparison with the traditional and digital learningprocess of primary school students. Integration of children with psychophysical development disorders into theeducational space of Russia as one of the directions of humanization of the entire education system,corresponds to the priorities of modern state policy. In Russia, the government is trying to do everything to catchup with European countries in terms of inclusion. For the successful education of children with special needs ofpsychophysical development, the inclusive school implements a program of psychological and pedagogicalsupport with the involvement of qualified speech therapists, speech pathologists, psychologists, socialeducators, teaching assistants and other specialists.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
