 English translation:Dynamic coefficient [of load]. Explanation:This in essence is a Factor of Safety when cranes pick up a load. The static weight of the load is increased by as much as three times to account for sudden movements (i.e. a slip of the brakes or a jerking motion on the line, etc.) of the crane while the load is on the hook.

stress expansion coefficient

Explanation:
That is, the factor by which the calculated stress is multiplied, in order to account for the increase in the actual stress to which the crane is subjected when a load is picked up or moved (suddenly or unexpectedly). The crane should be built to withstand not only the stress represented by the dead weight of the object(s) being lifted, but also the momentary increase or "spike" in the stress that occurs as the result of the motion of the object(s). -- Visualize, for instance, an Olympic weightlifter with the barbell in stationary position on the floor or over his head (as dead weight) and the same athlete in the act of picking up the barbell (with his body being subjected to the "expanded stress" created by moving the weight).
