Double girder overhead crane in the plant used more, Shenyang double girder crane, mounted on a wall or column at both ends of the plant, relying on the car's lateral and vertical movement to achieve weight lifting, loading and unloading, double girder crane refit In the metallurgical plant is the necessary equipment. Environment: generally applicable to the ambient temperature -10 ℃ to + 50 ℃, and at a temperature of 40 ℃ relative humidity less than 50, the lifting of the molten metal for forging hook, hook plate radiant temperature does not exceed 300 ℃. Working level: A7, A8 for relatively busy metallurgical foundry. Henan double girder overhead crane at both ends of the main beams of the longitudinal seam weld, the main beam has four longitudinal seam weld sequence by the case camber and lateral bending of the beam may be. Camber enough situation, you should cover about two longitudinal weld seam under, you can start straight from the end when welding automatic welding, manual welding should start from the middle to both sides symmetrical welding. Arch too large, it is necessary first of all on the cover of two longitudinal weld seam, lateral bending too much when the outside of the first welding seam, is too small to be the first welding of the weld. 18, shift recording this is not allowed in the cab, unified place to go on stage with the cab on the corner. Fill in the record required to go on stage, fill put in place. Fraud and deception, fill in false records, and offenders punished. Third, from the method of operation when lifting mechanism brake failure: First to conduct a spot car or reverse action, and issued an emergency signal immediately, while looking for a place to land hanging objects. Was hanging objects such as the location of which can fall, Ji An Shuangliang crane, it should control handle according to the normal method of operation to drop the last one, so hanging objects fall, never allowed to make hanging objects free fall. If circumstances do not allow direct whereabouts hanging objects, we must quickly go to the controller to handle stepwise increase in the last one, do not all of a sudden rise in the controller handle to the last stage, because the torque change large, will make the overcurrent relay contact is open the power cut off, so the weight immediately free fall, causing more accidents. While such reverse operation, but also quickly search for a suitable landing site object. Repeated reverse operation until finding a suitable landing site to an article.
