The rotating part of the cantilever crane is made up of 10 mm thick arm tube, and the planar bearing and ball bearing are used together. The strength of the mandrel shaft 80 is enough. The diameter of the column is enlarged, but it can be thinner, and the reinforcement is welded. For the loading and handling sites of heavy objects in various trades, it is very important to select the appropriate loading methods and means to improve the production efficiency and avoid damaging the body of the operator. Kindly lifts the lifting system tailor-made for customers. It plays an active role in protecting the health and safety of operators, ensuring the quality of products, improving production efficiency and saving labor.
In order to ensure that the mechanical equipment of the cantilever crane is always in a good technical state and can be put into operation at any time, reduce the failure shutdown date, improve the intact rate and utilization rate of the machinery, reduce the wear and tear of the machinery, prolong the service life of the machinery, reduce the operation and maintenance cost of the machinery, and ensure the safety of production, the maintenance and maintenance of the mechanical equipment must be strengthened. Maintenance of machinery must follow the principle of "paying equal attention to maintenance and giving priority to prevention". Regular maintenance and compulsory maintenance should be carried out, and the relationship between use, maintenance and repair should be correctly handled. No maintenance is allowed, no maintenance is allowed; all teams must do well in the maintenance of various types of machinery in accordance with the mechanical maintenance regulations and maintenance categories, without any reason. Delay, special circumstances need to be approved by the competent specialist can be postponed maintenance, but generally not more than half of the required maintenance interval; maintenance machinery to ensure quality, according to the provisions of the project and requirements, item by item, not missed or not insured.
Maintenance items, maintenance quality and problems found in maintenance should be well documented and reported to the department's special workers; maintenance personnel and maintenance departments should achieve "three checks and one pass" (self-inspection, mutual checks, full-time checks and one pass), constantly sum up maintenance experience, improve maintenance quality; asset management department regularly supervises and inspects the machinery of various units. Maintenance, regular or irregular spot checks and maintenance quality, and reward and punishment. Implementing and supervising the maintenance of machinery insists on popularizing the "cross" operation method with the main contents of "cleaning, lubricating, adjusting, tightening and anticorrosion", implements routine maintenance and periodic maintenance, and strictly follows the cycle and inspection and maintenance items stipulated in the instructions for use. Routine maintenance is the cleaning and inspection before, after and during the operation of machinery. It mainly inspects critical and vulnerable parts (such as mechanical safety devices), coolant, lubricant, fuel quantity, instrument indication, etc. Routine maintenance is completed by the operator himself, and the mechanical maintenance record is carefully filled out.
Primary maintenance: Cleaning, fastening and lubricating operations are generally carried out, and part of the adjustment operation to maintain the machinery in good condition. The use of unit assets management personnel in accordance with the maintenance plan issued under the "mechanical equipment maintenance, lubrication notice" to reach the operation team, by the operator himself to complete, the operation team monitor inspection and supervision.
Secondary maintenance: including all the contents of the first maintenance, with inspection, adjustment as the center, to maintain the mechanical assembly, mechanism, parts have good working performance. Operating group is mainly completed by the operator himself under the notice of mechanical equipment maintenance and lubrication issued by the asset management personnel of the using unit. If the operator himself has difficulties in completing, he may entrust the repair department to carry out inspection and supervision by the asset management personnel and the monitor of the operating group.
Season change maintenance: the main content is to replace the applicable season of lubricating oil, fuel oil, take anti-freeze measures, increase anti-freeze facilities. The organization shall be arranged by the use department to monitor and supervise the squad leader. Running-in Maintenance: After the running-in period of new machines and overhaul completed machinery, the running-in period maintenance must be carried out. The main contents are cleaning, tightening, adjusting and replacing lubricating oil, which is completed by the use department, inspected by the asset manager and supervised by the asset management department. Transfer Maintenance: Before the mechanical transfer site, should carry out the transfer maintenance, the operation content may carry on the maintenance according to the mechanical technical condition, may carry on the anticorrosion if necessary. The transfer and maintenance shall be arranged and implemented by the mechanical removal unit, inspected by the project department and the asset manager, and supervised by the asset management department.
Maintenance: stopping and sealing machinery should be maintained, mainly cleaning, anticorrosive, moisture-proof and so on. The stock machinery is entrusted by the asset management department, and the rest of the machinery is maintained by the use department. After the maintenance plan is completed, it must be carefully inspected and checked, and the relevant information should be compiled, so that the records are complete and true.
