The whole crane strictly follows the specification of JB/T5897-2006 “Explosion-proof Overhead Crane”, and the explosion-proof grade covers ExdⅡBT4 and ExdⅡCT4, which is suitable for the operation scenario with the rated lifting capacity of 1-20 tons and span of 7.5-31.5 meters, and the working temperature ranges from -20℃ to +40℃.
The overhead travelling crane can be used with BCD, BCDS, HB, HBS and other types of electric hoists, is a highly efficient small and medium-sized rail-type lifting equipment, widely used in oil refineries, petrochemical plants, gas stations, filling stations and other hazardous environments where flammable gases, dust or explosive mixtures exist, such as methane (CH4), acetylene (C2H2), ethylene (C2H4), ammonia (NH3), Carbon monoxide (CO), ethanol (C2H5OH) and other flammable and explosive places.
System Components
The structure of LB type explosion-proof single girder overhead travelling crane mainly consists of four main parts: the large vehicle running mechanism, the small vehicle running mechanism, the lifting mechanism and the electrical equipment. The bridge is supported on the elevated track of the plant or open yard by the running devices at both ends, and can move longitudinally along the track to cover a wide range of operating areas. The lifting trolley is mounted on the main beam of the bridge and runs horizontally along the trolley track, making the lifting operation flexible and precise. The electrical equipment adopts explosion-proof design, which conforms to strict explosion-proof standards and ensures safe operation in flammable and explosive environments. The overall structure is compact and smooth running, applicable to a variety of industrial scenarios.
Applications
LB type explosion-proof electric single girder overhead travelling crane is specially designed for flammable and explosive environment, and is suitable for dangerous places where explosive gas or dust mixtures exist. It is widely used in military industry, arsenal, petroleum, petrochemical, coal mine, chemical industry, aviation and other industries, and is able to safely and efficiently lift goods in workshops, warehouses and other occasions. The travelling overhead crane is particularly suitable for handling flammable and explosive objects or gases, such as petroleum products, chemicals, natural gas, etc. It ensures that the lifting tasks are completed under strict safety standards, and it is an indispensable lifting equipment in hazardous environments.
