Electric chain hoist cycles common sense protection

Any product has a protective cycle, electric hoist is no exception, if you can master the hoist protection period, hoist and trolley it will bring you great benefits, eliminating unnecessary overhead electric chain hoist purchase.
1 electric hoist in the design protection period, the surface does not exceed the ISO4628-3 rust rust grades in Ri3 level (equivalent to ASTMD610 of six or European standards Re3 grade)
2, A3.08, A3.11, A4.14, A4.15, etc. are ISO12944-5.
3, electric hoist the main consideration gloss finish selection and color retention, 4 files, PU412 aromatic polyurethane topcoat, PU413 aliphatic polyurethane topcoat, PU421 polyurethane topcoat electric hoist machinery, PU420 polyurethane engineering automotive finish.
4, no zinc primer (EPMisc.) consideration was mainly rust resistance and high solids, one can achieve a dry film thickness of 80 microns, optional epoxy zinc phosphate primer,wire rope winch epoxy bottom aluminum tripolyphosphate paint.
5, zinc-rich primer required dry film (or non-volatile parts of) zinc content (not the metal zinc content) ≥ 80%. Such as the use of the level GB_T_6890-2000 zinc (metallic zinc content ≥ 96%), the dry film can be converted into (or non-volatile parts of) zinc content (not the metal zinc content) ≥ 76.80%. Can also be taken as inorganic zinc (zinc silicate) primer.
6, the most commonly used in the paint is epoxy painted iron, because iron thin cloud is not high,manual block such as requiring a good surface appearance, good fineness can be replaced by an epoxy.
