If SLI is in operating condition then sLI itself will indicates that whether load is in safe mode. But if SLI is not working then one must be considered 40 % factor of safety of crane SWL and in SLI working condition it will be considered 20 % of its SWL.
The SWL stands for - Safe Working Load
1.6 ton The answer would be 40T, 1.6T is the WLL or SWL of an 8T nominal breaking strength rope.
You can buy a safety harness for work at www.uline.com/Safety-Harness. I would buy these new not used.
SWL means Safe Working Load
The initials SWL mean Safe Working Load
you can go to ebay.com or amazon.com to find great deals on a safety harness vest. and you can use your swag bucks to save even more money on your safety harness

TO CALCULATE THE SWL OF LIFTING WIRE ROPE THE FORMULAE CAN BE USED- 8*D2 WHERE 'D' IS THE DIAMETER OF WIRE ROPE IN 'mm' THIS WILL GIVE THE APPROX SWL (SAFE WORKING LOAD CAPACITY)
Cranes typically are designed with a FoS (Factor of Safety) of 5x the MBL (Minimum Breaking Load). So if the weakest part of the structure failed (e.g. in tension, compression or shear) at e.g. 100kN (10 metric tons), then the swl would be 10t / 5 = 2 tons

A safety harness is a type of device that is used to secure an individual to another object or thing. For instance, some amusement park rides use safety harnesses. Infant car seats also use a type of safety harness to keep the child secure within the seat.
