The safe working load can be calculated using the 6 x 19 &. 6 x 36 classification.
It depends on the density of the rope.
Fabric, Cable, Wire, Rope
AWG18 wire has a diameter of 0.0403 inches.
1.6 ton The answer would be 40T, 1.6T is the WLL or SWL of an 8T nominal breaking strength rope.
These are rule of thumb formulas but close to a manufacture's chart. for fiber core wire rope square the diameter times 42 = NBS Example, 1/2" x 1/2" x 42 = 10.5 tons UBS (Ultimate breaking strength) or NBS The formula is the same for IWRC, but use 45 as the multiplier, because of the higher strength in the rope. Example, 1/2" x 1/2" x 45 = 11.25 ton
wire rope has many other names such as wire,multi strand wire and flexible wire.to measure it with a diameter convert weigh by pounds per foot [b/f to kilometres per meter multiple that by 1.488 and to convert rope in minium breaking force in tons to kilo newtons multiply by 8.897 1lb =4.448 newtons and to convert rope in minimum breaking force in tons to kilo grams then multiply that by 907.2
1.4-ton
It is easy for wire rope with construction of 6x19,6x37 and 6x61 because all wires in a strand have the same diameter but for other construction needs math knowledge.
A sheave groove, such as the groove in a pulley, allows a rope or wire to pass through unhindered by friction or obstructions. The correct size sheave is required to minimize wear and tear on the rope or wire. When grooves become overly worn or are too large, they may allow excessive movement, which stresses the rope and reduces its life. A groove that is too small will compress the rope, breaking fibers or strands, and reducing the lifespan.
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)
For ropework a cable is simply a large rope, whether made of metal, hemp, or synthetic material. Wire rope and other rope is usually referred to as cable when it gets larger than 1 inch in diameter.
Wire rope has finer strands and more of them. Because of this, rope is more flexible and stronger. Rope tends to unroll and stranded wire will stay bent.
non galvanized means it will rust with moisture. wire rope is another name for stell cables used on elevatores , cranes bridges..ect... - - - - - It's something Home Depot doesn't carry. Galvanized wire rope has been dipped in zinc to keep it from rusting. Non-galvanized rope has to be coated in oil to keep it from rusting. Non-galvanized rope is usually pretty large - 1/2" diameter or larger.
