Single girder eot crane & Double girder eot crane

Eot cranes is the short form of electrical overhead travelling, also known as bridge cranes, overhead crane, is one type of material handling equipment to meet the lifting requirements of medium and heavy industries. Generally, an eot crane is a crane with a lifting hoist traveling along the cane bridge between parallel runways. The eot cranes mainly comes into two types, the single girder eot crane and double girder eot crane. In the following, the two types of eot cranes are presented to you. 

Why eot crane overload is dangerous?

Why eot crane overhead is so dangerous? Because the overloading of eot crane may cause the following dangers: 

• The excessive stress produced by the overload of the Eot crane can cause the steel wire rope to break, the driving parts are damaged, and the motor is burnt out.

• Due to the braking force is insufficient, crane brake can not hold brake lead to major accidents.

• Overload operation is very harmful to Eot cranestructure, On the typical example of this is caused by girder down warping, crack of cover board and web, de soldering and bring serious accidents of Eot crane safe operation.

• Because of the deflection of the main beam, the trolley track will deform along with the main beam. When the trolley is driven from middle to back, it is necessary not only to overcome the normal running resistance, but also to overcome the additional resistance caused by climbing. When serious, the trolley running mechanism, motor will be burned.

• In addition, the trolley will appear "slipping" phenomenon, the trolley itself, seriously affecting lifting operations. For the double girder Eot crane, it will cause the car "three legs" to run, because of the horizontal bending, it will make the small operation "gnaw rail" phenomenon.
