1 Description
1.1 Operating conditions
Supplementary to the instruction manual, the following documentation from the operator
must be noted:

Declaration of conformity

Log book

Spare parts list(s)

Circuit diagrams
Page and figure numeration:
The pages are consecutively numbered. Blank pages are not numbered, however are
calculated together with the consecutive pages.
Figures are numbered consecutively by chapter.
Example:
Figure 3-1 means: in chapter 3, figure 1
General:
The GCH series consist of the following models:
GCH, GCHK, GCHS, GCHHK, GCHHTD, GCHR
Classification according to application requirements:
Electric chain hoists and travelling gears are classified according to the following
regulations into ISO Groups:

DIN EN 14492-2

DIN 15400 (load hook)

FEM calculation regulations for series lifting equipment
(chain drive, motor, full load-life span)

ISO 4301-1: D (M3) = 400 h

Remarks about general revision (see chapter 4)
There is differing coefficient data for the ISO Groups that must be adhered to in
operation.
CAUTION !
The travelling gear is always classified as the same ISO Group as the
corresponding electric chain hoist.
NOTE
The ISO Group registration number of the electric chain hoist can be found
on the data plate.
The manufacturer will only guarantee the safety and lasting operation of the electric
chain hoist when used for applications that fall within its valid ISO Group coefficient
data.
Before the first start-up, the user must estimate according to the features in table 1-1,
which of the four types of load is applicable to the use of the electric chain hoist during
its whole service life. Table 1-2 shows standard values for the operating conditions of
the ISO Groups depending on the type of load and the time of operation.
Ascertaining the correct type of application for an electric chain hoist:
Either the running time or expected type of load can be used as a basis for ascertaining
the correct type of application for the electric chain hoist.
CAUTION !
Before starting up the electric chain hoist for the first time, it must be
determined with which of the load types shown in table 1-1 the electric chain
hoist is to operate. Assignment to a load type or a load collective (k) applies
for the entire operational life of the equipment and may not be altered for
operational safety reasons.
Example 1: Ascertaining permissible running time of the electric chain hoist:
An electric chain hoist of the ISO Group M4 is to be used for medium stress load tasks
throughout its entire service life. This corresponds to load type <3 heavy> (see table
1-1). According to the values in table 1-2, the electric chain hoist should not be used for
longer than 0.5 - 1 hour per working day.
