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 EDIII series have been designed for grade 1Am in the FEM regulations (FEM
9.511).
Details are provided in Table 4-2.
Average daily operating time and total operating time are determined by load distribution.
