Selection, installation and inspection of lifting machinery
　　
1.1 type selection
After the equipment arrives, the unpacking acceptance shall check whether the attached technical data are complete, whether the attached accessories, tools and accessories are consistent with the list, and whether the equipment and accessories are damaged and defective, and make unpacking acceptance records.
1.2 selection of installation unit
The installation team of lifting machinery can select qualified manufacturers to form a one-stop service mode of manufacturing, installation and commissioning. In addition, the selected installation unit must be a professional team with the special equipment installation (maintenance) safety approval certificate issued by the provincial quality and technical supervision department, and have the installation qualification for installing the corresponding lifting capacity. After the installation unit is determined, it shall assist the installation unit to handle the commencement report of special equipment before installation, and check whether the construction organization scheme, installation equipment, installation procedures, technical requirements, acceptance records of concealed works during installation and self inspection report of the installation team meet the requirements. After installation, the installation unit shall be supervised to conduct comprehensive self inspection, operation test and load test. After the self inspection is confirmed to be qualified, it shall be reported to the special equipment inspection institution for installation acceptance. After passing the acceptance and obtaining the safe use license, it can be put into use.
(2) rules and regulations for the use and management of lifting machinery
Comprehensively implement the regulations on safety supervision of special equipment and other laws, regulations and policies, adopt a series of technical, economic and organizational management measures, apply advanced scientific management methods and methods, and implement comprehensive management of lifting machinery, so as to achieve careful planning, selective selection, reasonable allocation, accurate installation, correct use, careful maintenance, scientific maintenance, safe production, regular inspection, timely transformation Timely scrapping and other whole process management. 　　
　　2.1Safety technologyarchives
Enterprises using hoisting machinery shall establish and improve equipmentSafety technologyArchives, lifting machinery archives include:
(1) relevant data such as ex factory technical data, product certificate, operation and maintenance manual, vulnerable parts drawing, electrical principle, electrical component layout, necessary safety accessory type test report, supervision and inspection certificate, etc. of lifting machinery.
(2) technical data, installation position and start-up time required during installation.
(3) acceptance certificate or periodic inspection report issued by special equipment inspection organization.
(4) daily maintenance, maintenance, overhaul, transformation, change, inspection and test records.
(5) equipmentaccidentPersonalaccidentrecord.
(6) equipment of superior competent departmentsafety evaluation 。
(7) maintenance and testing records of special equipment and safety accessories, safety protection devices, measurement and control devices and relevant auxiliary instruments and meters.
2.2 lifting machinerysecurity management system
To ensure the safe operation of lifting machinery, it is necessary to have perfect management rules and regulations, so that operators have rules to follow and managers have laws to follow. Improve and implement the special equipment organization and management organization, configure a strong professional management team, and maintain a relatively stable to meet the management requirements
2.3 special equipmentaccidentEmergency measures and rescue plan
(3) operation management of lifting machinery
3.1 management of operators
Operators shall learn and master the structure, working principle, technical performance, safety operation rules, maintenance and repair system and other relevant knowledge of the lifting machinery used and relevant national laws, regulations and standards before taking up their posts. By the local technical supervision departmenttrainOnly those who have obtained theoretical knowledge and practical operation skills can take up the post after passing the examination.
3.2 "three fixed" management of lifting machinery
"Three fixed" management refers to the system of specifying personnel, machines and posts. The "three fixed" system of lifting machinery is first of all the formulation of the system and the determination of the form of the system, in which the fixed personnel and the fixed machine are the basis. It is required that everyone has a post and a responsibility, and the crane platform is operated and managed by someone: "fixed post" responsibility is the guarantee.
3.3 regular inspection and maintenance management

(1) Daily inspection. (2) Weekly inspection. (3) Monthly inspection. (4) Annual inspection.
　　
(4) craneSafety technologyInspection contents:
Lifting machinerySafety technologyThere are two inspection methods, one is sensory examination; The other is to use test instruments and meters to measure and control the equipment.
4.1 sensory examination
See: according to the structural characteristics of the lifting machinery, observe the important transmission parts, the key points of the bearing structure, and the source of the fault phenomenon.
Listening: analyze whether the operation sound of each part of the lifting machinery is normal through hearing, judge the abnormal sound from the part, understand the cause and find out the source of the disease.
Olfactory: identify the on-site smell of the moving parts of the lifting machinery through olfactory, and identify the positions of overheating, wear and burning of the parts.
Q: ask the driver and relevant personnel about the fault prone points, fault process and category during the operation of the crane. Judgment craneSafety technologyStatus.
Touch: touch the operating parts of the crane by hand, and judge the fault location and fault nature according to the temperature change and vibration.
4.2 inspection of test instruments
4.3 safety inspection of general components of crane
(1) hook. 　　
(2) steel wire rope.
(3) braking device. 　　
(4) drum.
(5) pulley.
(6) reducer.
(7) wheel. 　　
(8) coupling..
4.4 inspection of crane safety protection device
(1) overload protection device.
Whether the overload protection device is sensitive and reliable and meets the design requirements, and the opening pressure of the hydraulic overload protection device; Whether the comprehensive error of mechanical, electronic and comprehensive overload protector alarm and power source cut-off set point meets the requirements.
　　（2）Torque limiter.
　　
　Torque limiterIt is a safety device for jib type crane to prevent overload and overturn. Check the sensitivity and reliability of the torque limiter by the increase method or the weight method, and check whether the comprehensive error of the set point of the torque limiter alarm and power source cutoff is within the specified range.
(3) limit position limiter.
Check whether the luffing mechanism, lifting mechanism and operating mechanism of the lifting equipment can generate alarm signals when they reach the set position distance, and automatically cut off the power source running in the dangerous direction.
(4) wind proof device.
(5) anti roll back device.
(6) buffer.
(7) protective device.
