Buenas tardes bona tada
Fijate en que dice:
Wll
Wll es la carga de trabajo, es decir la de rotura minorada por un coeficiente de seguridad
Other synonyms include Working Load Limit (WLL), which is the maximum working load designed by the manufacturer. This load represents a force that is much less than that required to make the lifting equipment fail or yield, also known as the Minimum Breaking Load (MBL). SWL or WLL are calculated by dividing MBL by a safety factor (SF). An example of this would be a chain that has a MBL of 2000 lbf (8.89 kN) would have a SWL or WLL of 400 lbf (1.78 kN) if a safety factor of 5 (5:1, 5 to 1, or 1/5) is used.
As such:
WLL = MBL / SF
Evidentemente el grillete aguanta mucho mas pero el fabricante recomienda esta carga como carga de trabajo “normal”
