(1) Determine the position of the crane's station according to the location of the equipment or components being hoisted, the specific conditions of the site, etc. Once the location of the station is determined, the amplitude is determined.
(2) According to the position height of the hoisting equipment or components of the bridge crane, the sling height of the equipment, and the position (amplitude) of the station, the arm length is determined by the characteristic curve of the crane.
(3) According to the above determined amplitude and arm length, the load of the crane can be determined by the characteristic curve of the crane.
(4) If the load that the crane can hoist is greater than the weight of the equipment or components being lifted, the crane is selected, otherwise it is re-elected.
1. Special equipment for purchase, introduction, installation and technical transformation must comply with the relevant national standards for quality and technical supervision, safety and hygiene regulations, especially for the selection and procurement of dangerous hoisting machinery. Recognition.
2. When the purchased crane is shipped from the factory, it must pass the safety technical inspection of the local municipal quality and technical supervision department, and obtain the "Crane Safety Technical Supervision Verification" and send it randomly.
3. The installation unit of the lifting machinery must obtain the qualification certificate. The installation personnel must have the operation certificate and the employment certificate to be able to install the lifting equipment and submit it to the superior safety and equipment authority for review and filing.
4. Before the crane is put into trial operation, the installation unit must first self-test and fill in the self-inspection report, and submit it to the receiving unit for pre-acceptance and acceptance (should have a complete record), which shall be tested and accepted by the superior supervisor and equipment department. Can be put into trial operation.
5. The formal acceptance must be carried out in accordance with the requirements of the technical, safety and equipment departments of the superior and the “three simultaneous” management standards for labor protection.
6. Strengthen the management of cranes. Seriously implement the various management systems and safety inspection systems for cranes, do regular inspection, maintenance and maintenance of cranes, eliminate hidden dangers in time, and keep cranes in good working condition.
7. Strengthen the education and training of crane operators, strictly implement safety operation procedures, improve operational technology capabilities and the ability to handle emergencies.
