2. Use shock absorbers of sufficient size.
Depending on the size of the work mass, the DGEA-... will withstand maximum
speeds without shock absorbers as listed in the chapter "Characteristic
curves".
Please note
Masses which suddenly slide down may cause injury to people in the vicinity of
a DGEA-... .
