The working environment of the oil drilling exploration site is extremely harsh. The large-size wire rope sling for lifting is a special tool for lifting and lowering the derrick and base of the oil rig. It is a key accessory in the lifting system of the oil drilling derrick. Its overall performance requirements are strict. Especially the low temperature performance requirements are more stringent, generally meeting the requirement of -45Celsius. The correct production process is the key to ensuring product quality. The manufacturing process of large-size steel wire ropes is divided into two parts: the manufacturing process of casting anchors and the casting process of large-size steel wire ropes. Casting anchorage is a machined part, for this reason, the relevant casting process of wire rope is worthy of attention.

Crane wire ropes are commonly used on construction cranes, and are generally braided by many high-strength crane wires. It firstly consists of single steel wires wound together to form strands, then some of the strands are wound into a rope core, and then outer strands composed of other strands are wound around the rope core to form a crane wire rope. Some imported crane wire ropes also contain a plastic ferrule, usually in the form of a plastic coating, which is specially treated to cover the rope core. The important crane wire ropes are filled with appropriate lubricants to reduce friction. Domestic crane wire ropes are generally divided into three types: organic (hemp core and cotton core), asbestos core or metal core according to the rope core material.

The service life of the wire rope has a great relationship with the method of use. Therefore, it should be used according to regulations, dragging and throwing are prohibited, overloading is not allowed during use, the wire rope is not allowed to bend at an acute angle, and the lifting speed is not allowed to change sharply. Avoid impact load;
