1. Lifting machinery product safety oversight
Lifting machinery manufacturing units for production of product safety and technical performance of self-inspection, after passing the area provincial department in charge of safety supervision and inspection techniques.
Inspection includes: raw POST data, metal structural safety technical requirements, electrical, hydraulic and control system safety requirements, safety equipment and major components safety requirements, operational tests and load tests.
2. In a regular supervision and inspection of lifting machinery
By the Special Equipment Inspection department is responsible for testing the use of lifting safety performance, installation and repair of safety and quality, and safety certification to be checked. Responsible for the crane inspection personnel must be approved by professional training, assessment, made at provincial level or above issued by the competent authorities crane inspector certificate, before an inspection report. Inspection includes:
(A) a working crane, every two years;
(2) After overhaul, new installation, transformation of the crane, the delivery before;
(3) cranes idle for more than a year, before re-use;
(4) After a natural disaster or a major accident, may make an important component performance and institutions harmed cranes, inspection after a disaster or accident.
Inspection items include technical files (such as product certification and instructions, inspection data, inspection and test records, personal accident records or equipment), the main components and safety devices, metal structure of the main force component, electrical and circuit protection, installation and operating environment. At the same time, but also for load test (load, static and dynamic loading) to confirm that the various components and bodies reliability.
In the run with a lifting test and load test can only load and the rated load test, which rated load test may be two inspection cycle once; were installed and major repairs of quality inspection, its operation and load tests must be in accordance with relevant standards.
3. Newly installed crane safety oversight
Newly installed crane safety oversight include:
(A) General requirements. Whole appearance, signs, nominal weight signs, operating environment, technical archives.
(2) metal structural safety technical requirements. Bridge, boom, tower, rack rails and other major lift force component and its connection; cab; platform, walkway, ladders, railings.
(3) organizations and major components and parts safety requirements. Lifting, running, slewing, luffing, retractable safety performance of other institutions in which the main components include hooks, wire rope and other lifting aids, reel, pulley, brakes, open gears, couplings, wheels and rails, etc. .
(4) Hydraulic system security technical requirements. Prevent overload safety device and the hydraulic impact, balance valve, hydraulic lock, lines and connections, operation and control devices.
(5) electrical and control system check. It includes power feeding device, the protection device, the control device, the wire and laying, Lighting, ground insulation.
(6) safety device test.
(7) running test and load test.
