4.2 Mechanical classification (Grade) and life
Safety and life for electric chain hoists are guaranteed only when the said equipment is operated in accordance
with the prescribed grade.
KITO electric chain hoists ER series are designed for grade 1Am, 2m in the FEM regulations (FEM 9.511) and
M4, M5 in the ISO regulations (ISO 4301) shown in Table 4-2. The grades are provided in Table 4-3 to Table 4-6.
Average daily operating time and total operating time are determined by load distribution.
