2.2 Operating Conditions
Classification according to usage conditions:
The chain hoists and trolleys are classified in drive groups according to the following guidelines:
DIN EN 14492-2
DIN 15400 (load hook) / DIN 15405 (safety load hook)
FEM calculation rules for series lifting equipment
(chain drive, motor, full load service life)
ISO 4301-1: D (M4) = 800 h
Information regarding general overhaul
Different standard values, which must be observed during operation, apply for the drive groups.
The manufacturer guarantees the safe and long-term operation of the chain hoist provided it is used
only in accordance with the standard values applicable for its drive group.
Before using the chain hoist for the first time, the operator must assess which of the four load types
applies to the usage of the chain hoist for the duration of its life cycle and classify the chain hoist
according to its drive group. The process for doing so is as follows:
The drive group of the chain hoist can be found on the data plate.
Step 1: Determining the load collective (factor k)
The daily load collective of a chain hoist forms a comparison value for the chain hoist capacity. The
load collective can be calculated based on the percentage of the indicated maximum load of the chain
hoist and the corresponding running time percentage of the chain hoist.
Alternative 1: Calculation based on the percentages of total running time at particular percentages of
maximum lift capacity according to the following formula:


K=0.5
Load type 2 –moderate
0.5>K<0.63
K=0.63
Load type 3 –high

Step 2: Determining the drive group according to load hours
Using the load collective determined in the first step, the appropriate drive group for the load on the
chain hoist can be determined based on the average daily running time of the chain hoist.
First, the average running time of the chain hoist per working day is calculated using the following
formula:
Average running time of the chain hoist per working day in h =
(lifting height in m x lifting operations per hour x 2 x working hours per day in h)
(lifting speed in m/min x 60)
To make things simpler, 1.3 times the average value of the lifting speeds of the creep and fast gears
can be taken as the lifting speed.
The drive group is then determined based on load hours using the following table.

Step 3: Determining the drive group according to switching operations
To calculate the switching load, the number of lifting operations must be multiplied by a factor of six
(6).
Calculation of the number of switching operations per hour:
Switching operations per hour = lifting operations per hour x 6
The drive group is selected according to the following table:
Step 4: Determining the drive group according to the duty cycle
The duty cycle of a chain hoist is the actual running time of the chain hoist during which the motor is
running relative to the overall usage time during which loads are being moved.
To make things simpler, the duty cycle can be calculated as a proportion of the running time of the
chain hoist per working hour using the following formula.
To make things simpler, 1.3 times the
average value of the lifting speeds of the creep and fast gears can be taken as the lifting speed.
The drive group is selected according to the following table:
Duty cycle
< 25%
< 30%
< 40%
< 50%
< 60%
Drive group
M3
M4
M5
M6
M7
Step 5: Selecting the correct chain hoist
The correct chain hoist can be selected according to the table in chapter 3.1. The drive group selected
must be the highest drive group as determined in the preceding steps:
Switching operations/h
<150
<180
<250
<300
<360
