Cov hlau nplaum hauv tsev yuav tsum ua raws li cov qauv xws li "Txoj Cai Tswj Kev Nyab Xeeb rau Lifting Machinery" (GB 6067) thiab "Technical Conditions for Electromagnetic Cranes" (JB/T 10744). Cov ntsiab lus tseem ceeb suav nrog cov ntsuas ntsuas, lub zog adsorption, nqa nrawm, thiab sib nqus ncej sib nrug. Thaum xaiv tus qauv, xyuam xim rau cov hauv qab no:
Cov yam ntxwv ntawm cov khoom: Cov khoom (ferromagnetic/non{0}}ferromagnetic), thickness, thiab nto roughness ntawm cov khoom raug lifted ncaj qha cuam tshuam rau adsorption nyhuv.
Ib puag ncig tej yam kev mob: High-kub, plua plav, thiab corrosive gas ib puag ncig yuav tsum tau cov cuab yeej nrog kev tiv thaiv siab dua (xws li, IP54 lossis siab dua).
Cov kev xav tau kev txawj ntse: Qee cov qauv siab - kawg yog nruab nrog lub zog sensors thiab qhov muag pom kev, ua kom muaj kev hloov pauv tsis siv neeg thiab ntau - tshuab kev sib koom tes.
