Steel Cable Diameter Strength

3 8 cable can hold the most weight but it really isn t that necessary as it s primarily for zip lines over 1000 feet.

Steel cable diameter strength.

Cable diameter diameter with coating breaking strength working load limit 5 1 design factor. Tensile strength of stainless steel wire. Where 5 16 steel winch cable breaks at 9800 lbs masterpull s 5 16 standard winch rope breaks at 12 300 lbs which is an okay strength increase. This data is for spooled wire.

The cold drawn steel wire undertakes not only tension but also extrusion shown in figure 8 9. Rope diameter minimum breaking strength safe load weight in mm lb f kn lb f kn lb m ft kg m 1 4. Wire rope with stop. Our stainless steel aircraft cable consists of thin steel wires that are stranded together to give the cable a combination of flexibility and strength.

The yield strength of the steel wire undertaking drawing once or more is improved by 40 60 and it has already lost the property of low carbon steel and become hard and brittle belonging to hard steel wire. Although the largest diameter of aircraft cable available at tyler madison maxes out at a it is lightweight and strong enough to meet special airline safety standards. The loss of strength due to bending wire ropes over the sheaves found in common use will not exceed 6 and will usually be about 4. For example our alien flier zip line kits use 3 16 or 1 4 diameter galvanized steel cable which can withstand weights of up to 250 lbs.

For straightened and cut lengths the minimum tensile strength will be be approximately 90 of the values listed in the table. Asme b30 5 mobile and locomotive cranes requires a design factor of 3 5 for 6 strand hoist ropes. Multipurpose 4140 alloy steel rods and discs. Show that the rope strength decreases in a marked degree as the sheave diameter grows smaller with respect to the diameter of the rope.

The cold drawn low carbon steel wire is made by tungsten alloy wire drawing model whose cross section is less than q235 or q215 coiled bars with diameter of 6 5 8 mm. This steel wire rope includes a hook with latch on one end for use with winches. The same standard requires a design factor of 5 0 for rotation resistant ropes. 1 8 3 16 1 760 lbs.

Their 5 16 superline however breaks at 21 700 lbs which is more than double the steel winch cable and a huge improvement in the safety factor. High strength wire rope. Spring temper values are in accordance with astm a 313. Wire rope in service is subjected to several kinds of stresses.

The mbf of starlift xtra is such that even with the 5 0 design factor.
