Abstract: Использование: в кранах, преимущественно козловых. Грузоподъемное устройство состоит из двух канатных барабанов 1 и 2. Барабаны соединены с приводом, а между собой - синхронной кинематической связью 3, например, в виде зубчатых колес 4 и 5. Между барабанами 1 и 2 размещен канатоукладчик, включающий каретку 18, которая может перемещаться по направляющей 19, механизмом подачи 20. Канат 6 закреплен своими концами 7 и 8 на концах рабочих частей 1 и 2. Ветвь 9 направлена на отклоняющий блок 10, соответственно ветвь 11 конца 8, навиваемая на барабан 2, направлена на 12. Диски 10 и 12 расположены между барабанами 1 и 2 в плоскости, касательной к образующим и проходящей через ветви 9 и 11, расположенные преимущественно соосно друг с другом. При нагружении каната 6 от усилия на подвеске 17 возникают крутящие моменты на барабанах 1 и 2. Ветви 6 и 9, 11, 14 и 15 получают одинаковые натяжения. При включении привода начинают синхронно вращаться, наматывая на себя (или разматывая) ветви 9 и 11, 6. Перемещение каретки 18 канатоукладчика с жестко прикрепленными к ней блоками 10 и 12 вдоль направляющей 19 и соответственно вдоль направления ветвей 14 и 15 обеспечивает укладку ветвей 9 и 11, 6 на барабаны 1 и 2 с заданным шагом. Ветви каната в любом положении каретки остаются соосны друг с другом, тем самым уравновешивают друг друга на пути движения каретки канатоукладчика и обеспечивают ее разгрузку от натяжения канатов. 3 ил.
