Safety precautions for bridge cranes

Bridge crane is one of the important mechanical equipment in industrial production. It is also called "crane" and is widely used in industrial production process. Bridge cranes have brought many benefits to the development of industrial production. However, it cannot be denied that there are still certain safety hazards in the use of bridge cranes, and various safety accidents also occur frequently. At present, the use of bridge cranes in industrial production needs to pay attention to the hidden safety hazards of bridge cranes and the corresponding preventive measures.

Brake

Braking is a very important function of bridge cranes in operation. It is controlled by brakes, which can control suspended objects in the air and realize braking functions such as parking. For bridge cranes, a good braking function is an important condition to ensure the safe operation of the crane. During the operation of the bridge crane, sometimes the brake fails, the equipment cannot brake the suspended object normally, and cannot prevent the suspended object from falling. The common reason for the failure to brake is that the brake arm of the device cannot normally deploy and brake due to a problem with the brake wheel of the brake.

To solve the problem of brake failure, the brake equipment of the bridge crane needs to be regularly inspected and repaired to ensure that the brake equipment can operate normally. If the inspection personnel find that there is a problem with the brake equipment, they must be replaced, and the brake must not be operated with the problem. In short, we must ensure the regular inspection and maintenance of the bridge crane brake equipment.

Wire rope

The wire rope of the bridge crane is an important support for the operation of the load-bearing equipment, and once the crane starts to operate, the force of the wire rope is very complicated. Under normal circumstances, wire rope breakage is a major manifestation of safety accidents in bridge cranes. The main cause of wire rope breakage or damage is because of long-term overload operation, which makes the wire rope unable to load. At the same time, the threading and winding of the wire rope will change its shape. The more this kind of straight shape changes, the more severe the wear of the wire rope. To strengthen the prevention of wire ropes, the Foshan crane manufacturer tells you that you should mainly start from these aspects:

1. The carrying capacity of the bridge crane should be avoided as much as possible, and the construction unit and individuals must prevent the overloading of the crane.

2. The wire rope selection of the bridge crane must be suitable for its work type and attributes, and the use of wire rope products also needs to meet the corresponding standards.

3. Regular inspection and maintenance of the steel wire rope should be carried out, especially the lubrication of the steel wire rope should be strengthened. The choice of lubricating oil should also comply with relevant maintenance regulations.

4. When encountering special circumstances, such as high temperature and environment with corrosive medium, the steel wire rope should be isolated and protected to prevent it from oxidation or corrosion.



The hook is a very important device of the bridge crane, which carries almost all the weight of the lifting materials. Once the hook is damaged or broken, it is easy to cause major safety accidents. The main reason for the breakage or damage of the hook is that the long-term friction of the overload load causes the deformation of the hook and even cracks and damage. To prevent safety hazards from the hook, first of all, it is necessary to strictly prohibit the crane from overloading and lifting, and to strictly control the crane's material carrying weight. Secondly, it is necessary to strengthen the inspection work of the hooks and evaluate the wear of the hooks. If the hooks have large wear or deformation, they must be adjusted as required. If the conditions are serious, such as cracks, they must be resolutely treated. Do not use repair welding blindly.

Reducer gear

The reducer is an important functional part of the bridge crane in the transmission process, and the crane uses a motor to adjust its transmission speed. The problem of the reducer may cause transmission failures such as tooth surface wear, breakage, and gluing in the gear engagement during the transmission process. To strengthen the elimination and prevention of the safety fault of the reducer, we should start from these aspects:

1. To ensure the smoothness of the transmission process of the bridge crane, it is important not to overload the transportation. The starting and braking of the crane must be carried out smoothly. Unless there are special circumstances, it is generally forbidden to reverse the vehicle.

2. The lubrication and maintenance of the reducer and gears should be carried out regularly, and the gears should be cleaned regularly to prevent other debris from clogging. At the same time, it is necessary to pay enough attention to the abnormal noise or tooth punching caused by the crane during operation, and conduct inspections in time. After investigation, it is determined that there are no safety hazards before it can be put into use.

Safe precautions

To ensure the safety and reliability of crane use from the management aspect, we must first adopt a variety of modern safety production management methods. Operators of cranes should be trained in operating skills. In the process of industrial production, select appropriate safety management methods, open a wide range of ways, contact the masses, discover problems in safety management in time, and propose corresponding solutions.

The operation of bridge crane is a very systematic and cumbersome work. If any aspect is not handled properly, it may cause safety accidents. Therefore, safety managers should understand the operating characteristics of bridge cranes and extensively collect a large number of previous occurrences. Incident information. On the basis of a detailed comparative analysis of accident data, a subjective and objective two-way analysis of the cause of the accident is carried out to find the cause of safety incidents during the use of the bridge crane, so as to provide the necessary practical basis for perfect safety management.

Before carrying out engineering operations, relevant personnel must follow the concept that safety is very important, and carry out detailed safety inspections on all links of the bridge crane before starting the operation to ensure the safety of the equipment. At the same time, the lifting equipment should be regularly overhauled. The overhaul should be carried out by a special inspector and related persons in charge to cooperate with the inspection, and make detailed inspection records.
