1: Use of the max. stress at working load.

Do not exceed the stresses at working load and limit stresses at the classification into the corresponding driving mechanism groups. Load in kgs which can be taken during operation. The properties of the austenitic materials with a lower hardness lead to a reduction of stress at working , when combined with a well lubricated chain, this produces a longer serice life. In cases of prolonged operation, a stress at working load of Otr=80N/mm2 at motor-driven hoists shouldn`t be exceeded.
