Safety Operating Regulations of Underhung Bridge Crane

Industry electric underhung bridge crane is a major lifting and transportation equipment in the production logistics process, and its utilization efficiency is related to the production rhythm of the enterprise. At the same time, underhung bridge cranes are also dangerous special equipment and may cause harm to people and property in the event of an accident. The driver of the overhead crane is the most active and critical factor in the use of the overhead crane. The driver’s ability to operate the kren atas kepala is very important and is a major issue directly related to the company’s efficiency and safe production. The author summarizes his own practical experience in operating bridge cranes and puts forward the following operating experience based on the characteristics of bridge cranes.

1. Master the characteristics of SEVENCRANE underhung bridge crane and work objects

To correctly operate a bridge crane, you must carefully master key elements such as the equipment principle, equipment structure, equipment performance, equipment parameters, and operating process of the equipment you are operating. These key factors are closely related to the use and operation of this equipment.

1. Grasp the principle of equipment

Pemahaman yang teliti tentang prinsip adalah prasyarat dan asas untuk pengendalian peralatan yang baik. Hanya apabila prinsip dikuasai dengan jelas dan mendalam, asas teori diwujudkan, pemahaman boleh jelas dan mendalam, dan tahap operasi boleh mencapai ketinggian tertentu.

2. Kuasai struktur peralatan dengan teliti

Menguasai struktur peralatan dengan teliti bermakna anda mesti memahami dan menguasai komponen struktur utama kren jambatan. Kren jambatan ialah peralatan khas dan strukturnya mempunyai keistimewaan tersendiri, yang mesti difahami dan dikuasai dengan teliti. Menguasai struktur peralatan dengan teliti adalah kunci untuk membiasakan diri dengan peralatan dan mengawal peralatan dengan mahir.

3. Kuasai prestasi peralatan dengan teliti

To carefully grasp the performance of the equipment is to master the technical performance of each mechanism of the heavy duty underhung bridge crane, such as the power and mechanical performance of the motor, the characteristic braking state of the brake, and the safety and technical performance of the safety protection device, etc. Only by mastering the performance can we better take advantage of the situation, scientifically control the equipment, delay the deterioration process, and prevent and reduce the occurrence of failures.

4. Kuasai parameter peralatan dengan teliti

Carefully mastering the equipment parameters means that you must understand and master the main technical parameters of the bridge crane, including work type, work level, rated lifting capacity, mechanism working speed, span, lifting height, etc. The technical parameters of each piece of equipment are often different. The technical parameters of the equipment are different, and there are differences in their performance. Careful knowledge of the exact parameter values for each overhead crane is critical to operating the equipment accurately.

5. Kuasai proses kerja dengan teliti

Menguasai proses operasi dengan berhati-hati bermakna menguasai langkah dan proses operasi pengeluaran yang disediakan oleh kren jambatan, dan berusaha untuk reka bentuk terbaik dan operasi munasabah prosedur pengangkatan dan pengangkutan yang digunakan dalam pelbagai proses. Hanya dengan mahir menguasai aliran proses kita boleh menguasai peraturan operasi, yakin dan beroperasi dengan bebas, untuk meningkatkan kecekapan kerja, keselamatan dan kebolehpercayaan.

2. Pahami perubahan status peralatan

Kren jambatan adalah peralatan khas, dan operasi dan operasi mesti memastikan status teknikal dan keadaan utuh kren jambatan. Semasa operasi kren jambatan, ia dipengaruhi oleh faktor seperti keadaan pengeluaran dan persekitaran. Fungsi dan status teknikal yang ditentukan semasa reka bentuk dan pembuatan asal mungkin terus berubah dan berkurangan atau merosot. Oleh itu, pemandu mesti berhati-hati memahami perubahan status peralatan, menjalankan kawalan operasi kren jambatan yang baik, dan melakukan penyelenggaraan dan pemeriksaan dengan berhati-hati untuk mencegah dan mengurangkan kegagalan.

1. Berhati-hati memahami perubahan status peralatan

Peralatan perlu diselenggara dengan teliti. Bersihkan, bersihkan, pelincir, laraskan dan ketatkan semua bahagian kren jambatan dengan kerap mengikut keperluan sistem penyelenggaraan. Tangani pelbagai masalah yang berlaku pada bila-bila masa tepat pada masanya, perbaiki keadaan operasi peralatan, atasi masalah dengan segera, dan elakkan kerugian yang tidak wajar. Amalan telah membuktikan bahawa hayat peralatan bergantung pada tahap penyelenggaraan yang besar.

2. Carefully grasp the status changes of the underhung cranes

Berhati-hati memahami perubahan status peralatan dan boleh menyemak peralatan. Fahami dan kuasai bahagian kren jambatan yang perlu diperiksa dengan kerap, dan kuasai kaedah dan cara memeriksa bahagian tersebut.

3. Skills in monitoring equipment through senses

Skills in monitoring equipment through the senses, i.e. seeing, hearing, smelling, touching and feeling. “Visual” means to use vision to observe the surface of the equipment in order to detect intuitive defects and failures. “Listening” means relying on hearing to detect the status of the device. The driver operates in the cab and cannot see the operating conditions of the equipment on the bridge. Hearing becomes an important auxiliary safety means. When electrical appliances or mechanical equipment are operating normally, they generally only emit very light harmonic sounds, but when they are malfunctioning, they will make abnormal noises. Experienced drivers can determine the approximate location of the fault based on the different changes in the sound. Therefore, identifying diseases by sound should be one of the internal skills of a driver. “Smell” means relying on the sense of smell to detect the status of the device. The electrical coil of the bridge crane catches fire, and the brake pads smoke and emit a pungent odor that can be smelled from a distance. If you find any peculiar smell, you should stop the vehicle immediately for inspection to avoid causing fire or other major equipment accidents. “Touch” is to diagnose the abnormal status of the equipment through hand feeling. Drivers sometimes encounter abnormal conditions in equipment and are able to diagnose and determine the cause of the malfunction. “Jue” here refers to feeling or feeling. Drivers will feel information from all aspects when operating, and experience will tell you what is normal and what is abnormal. When drivers find that they feel different from usual at work, they should immediately trace the source to avoid future troubles.

In short, it is the responsibility of the kren jambatan bawah gantung with complete runways driver to master and operate the overhead crane proficiently. SEVENCRANE has accumulated many years of operating overhead cranes, summarized and explored the above experience, and conducted an explanation and analysis, which is not comprehensive. We hope that this can attract criticism and guidance from colleagues and promote the common improvement of overhead crane drivers’ operating skills.
