Precautions for overhaul of single beam crane

Single beam crane is an important tool produced in the workshop. Once the crane fails, it will affect the entire production schedule. Therefore, it is necessary for hoisting machinery to have specialized repair personnel to ensure that when a failure occurs, the failure can be eliminated in time and production can be restored. The repair of single girder cranes must be carried out by a qualified manufacturer, which mainly meets the following requirements.

Repair personnel should obtain special equipment operation certificates issued by the state and submit relevant certificates to the owner for record. Operators must wear personal labor protection equipment, including safety helmets, safety belts, warning belts, etc., when performing maintenance work on single-beam cranes. Strictly operate in accordance with traffic safety operating regulations, and strictly prohibit illegal operations. During the overhaul of single-beam cranes, it is necessary for the maintenance personnel to comply with the owner's safety management regulations and the organization of the owner's management personnel.

After each repair is completed, the repairer should provide repair records, including the repair content of the single-beam crane, the replacement of consumables, and the name and quantity of the accessories. The repair records of single girder cranes shall be signed and approved by both sides. After receiving the call from the owner, the repair party should organize personnel to the site for repairs as soon as possible. Generally speaking, general problems should be resolved within 2 hours. Communicate with the owner in time for special faults. Resolve within 24 hours after Party B acknowledges.

The operating environment also has a certain impact on the single beam crane. For example, the use of acid gases in the environment will accelerate corrosion and component damage. High temperatures can cause aging of wires, cables, and electrical components.

Operators of single-girder cranes must undergo training and obtain an operating certificate before they can take up their posts. Unlicensed operation not only ensures safety, but also causes frequent equipment failures and affects the service life of the equipment. For example, the cable duct of an electric hoist may be damaged by a tipping crane. Suspension overload will cause deformation of the main beam. Frequent operation of the remote control may cause electrical failure. Therefore, the standard operation can not only reduce the failure rate, but also extend the service life.

The price of single girder cranes is very high. The application value of the single beam crane is to extend its service life. The design life of a single beam crane is 25 years, but it cannot be used in practice due to various reasons. The main factors affecting the service life of the equipment are improper operation, improper protection and improper operating conditions.

Single beam crane is a kind of special equipment. The state requires that special equipment be repaired and maintained by qualified manufacturers. How to do the repair and maintenance of single beam cranes? Carry out protection and maintenance every year, every month, and every week to eliminate faults and potential safety hazards in advance. However, some users did not pay attention to this and did not protect the equipment, which accelerated the aging of the single beam crane components. As time goes by, the service life is shortened.

If a repairer needs to replace and repair spare parts after diagnosing a driving failure, in principle, the owner shall provide it, and the repairer shall be responsible for the replacement and repair. If a single-girder crane discovers a major safety hazard, it shall immediately notify the handling personnel of Party A’s lifting machinery and put forward corresponding rectification suggestions.
