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 mostni žerjav 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

Natančno razumevanje principov je predpogoj in osnova za dobro delovanje opreme. Šele ko so načela jasno in globoko obvladana, je teoretična osnova vzpostavljena, razumevanje je lahko jasno in poglobljeno, raven delovanja pa lahko doseže določeno višino.

2. Skrbno obvladajte strukturo opreme

Skrbno obvladovanje strukture opreme pomeni, da morate razumeti in obvladati glavne konstrukcijske komponente mostnega žerjava. Mostna dvigala so posebna oprema in njihove konstrukcije imajo svoje posebnosti, ki jih je treba natančno razumeti in obvladati. Skrbno obvladovanje strukture opreme je ključ do poznavanja opreme in spretnega nadzora opreme.

3. Previdno obvladajte delovanje opreme

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. Previdno obvladajte parametre opreme

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. Skrbno obvladajte delovni proces

Skrbno obvladovanje postopka delovanja pomeni obvladovanje proizvodnih korakov in procesov, ki jih uporablja mostni žerjav, ter prizadevanje za najboljšo zasnovo in razumno delovanje postopkov dviganja in transporta, ki se uporabljajo v različnih procesih. Le s spretnim obvladovanjem poteka procesa lahko obvladamo pravila delovanja, smo samozavestni in svobodno delujemo ter tako izboljšamo delovno učinkovitost, varnost in zanesljivost.

2. Ujemite spremembe statusa opreme

Mostni žerjav je posebna oprema, delovanje in delovanje pa morata zagotoviti tehnično stanje in nepoškodovano stanje mostnega žerjava. Med delovanjem mostnih žerjavov nanje vplivajo dejavniki, kot so proizvodni pogoji in okolje. Funkcije in tehnični status, določen med prvotnim načrtovanjem in proizvodnjo, se lahko še naprej spreminjajo in zmanjšajo ali poslabšajo. Zato mora voznik natančno razumeti spremembe statusa opreme, izvajati dober nadzor nad delovanjem mostnega žerjava ter skrbno izvajati vzdrževanje in preglede, da prepreči in zmanjša okvare.

1. Previdno preglejte statusne spremembe opreme

Opremo je treba skrbno vzdrževati. Redno čistite, čistite, namažite, nastavljajte in zategnite vse dele mostnega žerjava v skladu z zahtevami sistema vzdrževanja. Pravočasno odpravite različne težave, ki se pojavijo kadar koli, izboljšajte pogoje delovanja opreme, začnite težave v kali in se izognite nepotrebnim izgubam. Praksa je pokazala, da je življenjska doba opreme v veliki meri odvisna od stopnje vzdrževanja.

2. Carefully grasp the status changes of the underhung cranes

Previdno preglejte statusne spremembe opreme in lahko preverite opremo. Razumeti in obvladati dele mostnega žerjava, ki jih je treba pogosto pregledovati, ter obvladati metode in sredstva za pregledovanje delov.

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 podvisni mostni žerjav 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.
