Gantry cranes and special detection routine testing content

Gantry crane crane safety testing is the basis for safety evaluation, in order to get the status of the case  gantry crane ,  crane must carry out safety testing. Crane safety testing and many kinds, according to the actual situation, can simply be divided into two categories: Routine testing and special testing.

Routine testing is primarily based on safety and technical inspection issued by the state outline and enterprises to carry out the testing procedures, including:

① Technical File Checker. Including  eot crane  product certificate, the installation instructions (including the main performance parameters of the crane, range), drawings (general diagram, electrical schematics, electrical wiring diagram, hydraulic system diagram), the main components or product quality guarantee certificate (hanging hook, wire rope, overload protection devices, etc.), the crane should installation, adjustment, alteration, repair, incident handling and other technical records;

② metal structure inspection. Including weld inspection, checking connections, structural safety inspection;

③ main parts inspection. Including hooks, wire rope, drum, pulleys, brakes, etc. These components must comply with GB3811-83 " bridge crane  design specifications" and GB6067-85 "crane safety regulations" requirements;

④ Electrical installations inspection. Including the power supply, circuit breakers, the control circuit, slip line, wire and cable, electrical wiring, etc.;

⑤ safety device checks. Including overload protection, torque limiter, up (down) position limiter, chain protection devices, buffers, wind devices;

⑥ running test. Including air load test, static load test, dynamic load test.

Special testing is routine testing for routine testing on the basis of doubts or questions arise in-depth testing, special testing generally want to use detection equipment. Shame common are:

Welds NDT testing, metal structure thickness measurement, metal structural stress testing, materials testing chemical analysis and mechanical properties, mechanical parts mechanical calculation, load-bearing structural stress performance accounting, accounting and other machine design.
