Isolation crane is a double girder overhead crane with the insulation crane hook. It a kind of material handling equipment used to lift and transport loads in charged environment, such as the plants where electrolyse non-ferrous metals, such as magnesium, aluminum. Isolation crane is a heavy duty overhead with double brake in the hoisting for ensuring safety. The lifting capacity of the isolation crane is 5 to 50 tons and the working class is A6. The specific parameters of the overhead crane is as follow:
Isolation crane is consisted of four main parts, the box-type bridge structure, crane travelling mechanism, trolley, electric parts, and others, etc.
Isolation crane drawing
Isolation crane is used for material handling and lifting, equipment installation and maintenance in electrolysis nonferrous plants for smelting aluminum, magnesium, lead, zinc and others, etc.
1. Insulation measures of isolation cranes
In order to prevent the crane and operator from danger of current to ensure their safety, there are three insulated devices equipped on the isolation crane, which are placed between:
2. Bridge frame
As the main force component of isolation, the bridge frame is mainly consisted of double beam, double track, end beams, trolley tracks, walkways, railings, ladders, and other metal structures.
3. Driver’s cabin
Driver’s cabin is a closed and tempered glass cabin, which is the workplace of crane operator, therefore the driver’s cabin has to be durable, safe and reliable, and at same time it should provide the driver a good vision and enough comfortableness. The features of driver’s cabin are as follow:
4. Crane traveling mechanism
The traveling mechanism of isolation crane: During operation, driving wheels never slip; when braking, it is steady and reliable.
5. Trolley parts
Main and auxiliary hoisting mechanisms of isolation crane have separate driving device, which can lift and handle loads independently and can coordinate to complete the work of turning loads over. Dual braking is used by the hoisting mechanism.
6. Isolation Crane Safety Protection Device
