Remarks
(1) If your working temperature and humidity are out the range of the value in the table, please
ask your distributor for related data.
(2) Expected operation ways:The hoist is designed to vertically lift in normal atmosphere and
working conditions.
(3) The standard of noise degree is the value measured at 1 meter from the machine under the
normal operation.
2.2 Machine degree and service life
The service and safety of the electric chain hoist can be guaranteed only under the condition
that it is operated according to the following.
The design of the hoist conforms to lAm of FEM(Table 2.21)
The description is detailed in table 2.2
The average operation hours per day and total operation hours are calculated on the basis of
load distribution.
