Bridge cranes are one of the main lift transport equipment in the production of logistics, and their efficiency is linked to the production rhythm of enterprises. At the same time, the bridge crane is a special equipment of greater risk, which may cause harm to persons and property in the event of an accident。
The driver of the bridge crane is the most active and critical factor in the use of the bridge crane, and the high and low level of driver's ability to operate the bridge crane is of great importance and is directly related to the effectiveness of the enterprise and safe production. Taking stock of the practical experience gained in operating the bridge cranes themselves, the writer proposes the following operational experience in relation to the characteristics of the bridge cranes。
I. Maintenance of equipment qualifications and particular findings
The proper operation of a bridge crane requires careful control of key elements such as equipment principles, equipment construction, equipment performance, equipment parameters and operational processes of the equipment you operate. These key elements are closely linked to the operation of this facility。
1. Rationale for holding equipment
Careful understanding of the principles is a prerequisite and basis for the application of well-functioning equipment. The doctrine is clearly developed in depth and provides a theoretical basis for understanding in order to be clear and profound and to apply the operational level to a certain level。
2. Careful control of equipment construction
The mastery of equipment construction is the need to understand the main structural components of mastery of the bridge crane. The bridge crane is a special equipment whose construction is unique and must be carefully understood and controlled. Careful mastery of the equipment's construction is key to familiarity with the equipment and skilled driving equipment。
3. Careful control of equipment performance
Careful control of the performance of the equipment means mastery of the technical capabilities associated with the various institutions of the bridge crane, such as the power and mechanical performance of the electric motor, the characterization of the brakes and the safety technology of the safety protection devices. The mastery of performance allows better control of equipment by seditiousness and science, slows down the process of deterioration and prevents and reduces malfunctions。
4. Careful control of equipment parameters
A careful grasp of the equipment parameters is the need to understand the main technical parameters of mastery of the bridge crane, including type of work, level of work, rated lifting weight, speed of institutional work, extent of work, elevation, etc. The technical parameters for each equipment often differ. The technical parameters of the equipment vary, and the performance of the equipment varies. Careful control of the exact parameters of each bridge crane is essential for the precise operation of the equipment。
5. Careful management of operational processes
The mastery of the operating process is the mastery of the production process steps and processes served by the bridge crane, and the optimal design and rational operation of the transport procedures used in the various processes. It is by mastering the process that it is possible to keep track of the rules of the operation, to have a sound mind and to operate as it is, to achieve greater efficiency and safety。
Ii. Keeping the equipment state change
The bridge crane is a special equipment operating to ensure the technical and sound state of the bridge crane. In the course of their operation, bridge cranes are affected by factors such as production conditions and the environment, and the functional and technical state determined at the time of the original design may change and decrease or deteriorate. Therefore, in order for the driver to be careful about the change in the condition of the equipment, it is necessary to exercise good operational control over the bridge crane, carefully perform maintenance checks to prevent and mitigate malfunctions。
1. Carefully grasp the change in the state of the equipment
The equipment needs to be carefully maintained. As required by the maintenance system, all parts of the bridge crane are regularly cleaned, cleaned, lubricated, adjusted and secured. To deal in a timely manner with immediate problems and to improve the operating conditions of the equipment in order to avoid undue losses. The lifetime of the equipment has proven to be largely determined by the level of maintenance。
2. Carefully grasp the changes in the state of the equipment
Carefully grasp the changes in the state of the equipment and check the equipment. Knowledge of the parts of the bridge crane that require frequent inspection and of the methods and methods of inspection。
3. Skills for sensory surveillance equipment
Skills in sensory monitoring equipment, i. E., visual, hearing, smell, touch, sense. " vision" means visual observation of the surface of the equipment with a view to visual defects and malfunctions。
“listening” is the use of hearing detection devices. The driver operated in the cab and could not see the condition of the equipment on the bridge. Hearing becomes an important subsidiary security tool. Electrical or mechanical equipment normally functions with only a very mild sound, while the disease is operated with an abnormal noise. Experienced drivers are able to judge the approximate parts of the malfunction on the basis of variations in their voices. Therefore, sound recognition should be part of the driver's talent。
"sniffing" is the use of sniffing equipment to detect state. The bridge crane wires are on fire, and smoke on the brake pads can smell the smell of stingy noses and can be smelled from a distance. Distinction should be detected and stopped as soon as possible to avoid fires or other major equipment accidents. "touching" is the diagnosis of the abnormal state of the equipment by hand. Drivers sometimes encounter an abnormal state of equipment and are able to diagnose the cause of failure。
"i feel" here means feeling or feeling. Drivers are exposed to information from various sources and experience tells you what is normal and what is abnormal. In the course of their work, when they find out that they feel different from normal, the driver immediately pursues the root cause in order to eliminate the after-effects。
Iii. Conclusion to the ground cool
The operation of a bridge crane to carry out a lifting operation requires the cooperation of a number of persons, including drivers, commanders, persons tied up and sometimes within its scope, as well as other equipment and operational personnel, so that the driver must work with care and ground operations in order to communicate with the personnel and must be identified for the target, the state of the equipment, the operational instructions and the operational environment。
Drivers must establish command language with ground personnel before operating. Operations cannot be conducted without an agreement on the language of command. Drivers must be focused in their operations and operate on the signal of the commanding officer. Before each assignment, the driver should ring the bell to alert the operator. At the same time, care is taken to observe the surroundings of the suspension. No one shall be allowed to remain under the articles and under the arms and in the area where they are to be hanged. When the observation line between the driver and the suspension may have been obstructed during the suspension, the driver should have carefully examined the physical environment within the area of the suspension prior to the suspension and confirmed the course of the suspension. During the suspension, signal contact with the commanding officer was strengthened, while the commanding officer was to be placed in the driver's sight to conduct the command and to avoid a security incident involving the suspension from sight. If only drivers and hookers work on the ground, the driver must work closely and at the same pace. Movement and lifting of loads shall only be carried out by means of a signal from a connector, but a “stop” signal shall stop immediately, regardless of who sent it。
To properly judge the character of the state of emergency and take appropriate emergency measures。
Bridge cranes are more dangerous equipment, which, once out of control, may cause loss of property and loss of life. As drivers of bridge cranes, the attributes of a state of emergency should be correctly judged and appropriate emergency disposal measures taken, and the skills required to make a dangerous situation dangerous or to minimize accident losses should be the requisite。
The state of emergency for the bridge crane can also be described as a state of imminent danger for the bridge crane, which is characterized by the sudden emergence of a dangerous, non-functioning, uncontrollable state of equipment (facilities), which, if misdisposed, would result in an accident. The types of emergency for the bridge cranes are very diverse, with a high probability of failure of the lifting brakes, sudden power outages of the cranes, out-of-control of the bus control agencies, broken wire and wire lines, a fire on the cranes, and failure of the lifting agencies to rise limits. There can only be risks, and we should be intellectually well prepared to create contingency plans。
In addition, the operational procedures for production should be taken into account in order to work better and avoid accidents. For example, in the event of a failure of an lifting brake when there is a heavy object on the crane hook, the heavy object falls and the driver should ring the bell or a siren continuously to signal all personnel at the scene to avoid it。
Summary
The main command for the operation of the bridge crane is the responsibility of the bridge crane driver, who has accumulated over the years through the operation of the bridge crane and has taken stock of the above-mentioned experience and analysed it in a less comprehensive manner. It is hoped that the bricks will lead to critical points from a wide range of peers and will facilitate the common upgrading of the operational skills of bridge crane drivers。

Metallurgical suspension is widely used in steel plants and is an important mechanical device for the steel chain. Compared to normal bridge cranes, metallurgy-specific high-temperature operating environments are extremely challenging for the safe management of operators and equipment。
Large lifting equipment, such as metallurgy, ship-building, and door-boarding, are required to be equipped with a security surveillance system, in accordance with standards such as the gb/t 28664-2017 safety control management system for cranes and the tsg 51-2023 technical safety protocol for cranes。
This type of equipment is not only extremely expensive per unit, but is frequently used, with a significant proportion of the equipment having a long life span, the security surveillance system not configured at the plant or damaged due to the long duration of the installation. The early security surveillance system only serves drivers ' reminders, does not allow remote monitoring and does not meet the digital needs of enterprises。
