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 桥式起重机 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

认真理解原理是设备良好操作的前提和基础，只有原理掌握清楚、深入，理论基础打好，理解才能清晰深刻，操作水平才能达到一定的高度。

2.认真掌握设备结构

认真掌握设备结构，就是必须了解和掌握桥式起重机的主要结构部件。桥式起重机是一种特种设备，其结构有其特殊性，必须认真了解和掌握。认真掌握设备结构是熟悉设备、熟练操控设备的关键。

3.认真掌握设备性能

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.认真掌握设备参数

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. 认真掌握工作流程

认真掌握操作工艺，就是要掌握桥式起重机所服务的生产操作步骤和工序，力求各工序所用到的起重运输工序做到最佳设计和合理操作。只有熟练掌握工艺流程，才能掌握操作规律，胸有成竹，操作自如，提高工作效率、安全性和可靠性。

2.掌握设备状态变化

桥式起重机为特种设备，操作、操作必须保证桥式起重机的技术状态和完好状态。桥式起重机在运行过程中，受生产条件、环境等因素的影响，其原设计、制造时确定的功能和技术状态可能不断发生变化而降低或恶化。因此，司机必须认真掌握设备的状态变化，做好桥式起重机的操作控制，认真做好维护和检查，防止和减少故障。

1.认真掌握设备状态变化

设备需要精心保养。按照保养制度的要求，定期对桥式起重机各部件进行清扫、清洁、润滑、调整、紧固等工作。及时处理随时出现的各种问题，改善设备运行状况，防患于未然，避免造成不应有的损失。实践证明，设备的寿命很大程度上取决于保养的程度。

2. Carefully grasp the status changes of the 悬臂起重机

认真掌握设备的状态变化，能够对设备进行检查。了解和掌握桥式起重机经常需要检查的部位，掌握检查这些部位的方法和手段。

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 下悬桥式起重机 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.
