What is the breaking load of special improved plow grade wire rope per square inch?

The breaking load of special improved plow grade wire rope is indeed around 120-130 tons per square inch. This type of wire rope is known for its high strength and durability, making it suitable for heavy lifting applications. The specifications relating to breaking loads are critical for ensuring safety and reliability in rigging and lifting operations.

The high breaking load is due to the wire rope's construction, which includes a greater number of wires and a more robust design compared to standard wire ropes. This enhanced construction allows it to handle more force without failing. Understanding this value is essential for millwrights and rigging professionals as it directly informs the selection of appropriate lifting equipment for various tasks.

In practice, using a wire rope that meets or exceeds these breaking load specifications is crucial for maintaining safety standards during lifting operations, as it allows for a larger margin of safety when handling heavy loads.
