      <abstract xml:lang="ru">
        <p>Разработка надежных предохранительных устройств для улавлива­ния падающей клети при обрыве подъемного каната является одним из вопросов, не получивших до настоящего времени удовлетворительного конструктивного решения. Выработка же конструкции надежно работающих парашютов для остановки падающей клети необходима в связи с переходом горных ра­бот на разработку глубоких горизонтов и связанного с этим повышения скорости движения клетей.</p>

        <p>The development of reliable safety devices to catch the falling stand at the breakage of the hoisting rope is one of the issues that have not received to date a satisfactory design solution.Development of the design of reliably working parachutes to stop the falling stand is necessary in connection with the transition of mining operations to the development of deep horizons and associated with this increase in the speed of movement of stands.</p>
