Operating Skills of Overhead Cranes

Overhead 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, overhead 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 overhead crane is very important and is a major issue directly related to the efficiency of the enterprise and safe production. This article summarizes the practical experience accumulated by our factory drivers in operating overhead cranes, and proposes the following operating experience based on the characteristics of overhead cranes.

1. Master the characteristics of equipment 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. Master the principle of equipment

A careful understanding of the principles is the prerequisite and foundation for good operation of equipment. Only when the principles are clearly and deeply mastered, the theoretical foundation is established, the understanding can be clear and profound, and the operation level can reach a certain height.

2. Carefully master the equipment structure

Carefully mastering the equipment structure means that you must understand and master the main structural components of the bridge crane. Bridge cranes are special equipment and their structures have their own particularities, which must be carefully understood and mastered. Carefully mastering the equipment structure is the key to being familiar with the equipment and skillfully controlling the equipment.

3. Carefully master equipment performance

To carefully grasp the performance of the equipment is to master the technical performance of each mechanism of the 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. Carefully master equipment parameters

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. Depending on the technical parameters of the equipment, there are differences in its performance. Careful knowledge of the exact parameter values for each overhead crane is critical to operating the equipment accurately.

5. Carefully master the work process

Carefully mastering the operation process means mastering the production operation steps and processes served by the bridge crane, and striving for the best design and reasonable operation of the lifting and transportation procedures used in various processes. Only by proficiently mastering the process flow can we master the operation rules, be confident and operate freely, so as to improve work efficiency, safety and reliability.

2. Grasp the status changes of the equipment

The bridge crane is special equipment, and the operation and operation must ensure the technical status and intact condition of the bridge crane. During the operation of bridge cranes, they are affected by factors such as production conditions and environment. The functions and technical status determined during the original design and manufacturing may continue to change and be reduced or deteriorated. Therefore, the driver must carefully grasp the status changes of the equipment, conduct good operation control of the bridge crane, and perform maintenance and inspections carefully to prevent and reduce failures.

1. Carefully grasp the status changes of the equipment

The equipment needs to be maintained carefully. Clean, clean, lubricate, adjust and tighten all parts of the bridge crane regularly in accordance with the requirements of the maintenance system. Deal with various problems that occur at any time in a timely manner, improve the operating conditions of the equipment, nip problems in the bud, and avoid undue losses. Practice has proved that the life of equipment depends to a large extent on the degree of maintenance.

2. Carefully grasp the status changes of the equipment

Carefully grasp the status changes of the equipment and be able to check the equipment. Understand and master the parts of the bridge crane that need to be inspected frequently, and master the methods and means of inspecting the parts.

It is the responsibility of the overhead crane driver to master the essentials of operating overhead cranes. The author has accumulated many years of operating overhead cranes, summarized and explored the above experience, and conducted an explanation and analysis, which is not comprehensive. I hope that this can attract criticism and guidance from colleagues and promote the common improvement of overhead crane drivers’ operating skills.
