Подъемное устройство элементов электрического шкафа

Полезная модель относится к электротехническому оборудованию, в частности к устройствам монтажа и демонтажа габаритных или тяжелых элементов электрического шкафа. Устройство выполнено с возможностью, предпочтительно рельсового, крепления на крыше электрического шкафа, при этом элементы конструкции лебедки находятся выше плоскости крыши электрического шкафа, а рама подъемного устройства в нижней части выступа за лицевую сторону электрического шкафа имеет отверстия, совпадающие с направляющими, монтируемого устройства. Полезная модель обеспечивает повышение эргономичности выполнения операции монтажа элементов электрического шкафа. Так, за счет выполнения отверстий, соответствующих направляющим монтируемого элемента, в раме устройства механическим путем достигается повышение точности позиционирования элементов электрического шкафа в его верхней части, при этом не снижается точность позиционирования в других частях шкафа, что упрощает монтаж элементов, так как у пользователя нет необходимости самостоятельно с использованием физической силы позиционировать массивные и крупногабаритные элементы. А за счет размещения элементов конструкции лебедки выше плоскости крыши электрического шкафа пользователь получает возможность поднимать монтируемые при помощи подъемного устройства элементы электрического шкафа по всей его высоте, что также обеспечивает повышение эргономичности выполнения операции монтажа.
