Wire Ropes & Its specifications


Before heading anything regarding wire rope industry we will understand the basics of wire rope and its specification-

wire ropes- wire rope has a unique design consisting of steel wires that form individual strands in a helical pattern around a center core. wire rope is a complex mechanical device that has many moving parts all working in tandem to help support and move an object or load.
usage of wire ropes-
Wire rope has been used in a large scale in industrial and construction area. wire rope are used dynamically for lifting and hoisting in cranes, elevators, buildings lift, construction work etc.
wires have for many years played an integral role in the daily operation as in industrial industry, construction industry and in various industries whereas it used.

safety, usage and care of wire ropes-

The use, care and maintenance of wire ropes  should be included in every vessel's safety management system. Before going in deep understanding of wire ropes care and maintenance it is useful to understand wire ropes construction
wire rope is fabricated from strands of precise individual wires. the configuration of the wires and strands making up the wire rope is designed and manufactured to be able to be work together and move with respect to one another to ensure the rope has the flexibility necessary for successful operation.
Principal causes and damage
corrosion-
storage in the main deck exposes the wire to high levels
The small diameter of wire required limits of effectiveness of internal core lubrication and weakens the wire resistance to corrosive damage.
Abrasion
Damage often occurs as a result of pulley and sheave  seizure.
Cutting in-
This occurs when rope buries itself in a tension in a wire that has been spooled poorly underneath of wire ropes.

Some general information about chain sling & wire rope sling


Chain Sling- Chain slings are generally used in conjunction with a crane, powered hoist, manual and lever hoist or other type of lifting device. Before you select a chain sling, it is important to understand the application of slings. It is very important to understand that what kind of slings will be suitable for the industrial/construction industry, Because slings equipped with so many characteristics such as its weight, sling angles, number of attachment points. So you should have an idea about these features when you are about to buy chain slings. This will help you to choose the right sling for the task.

Wire rope slings- It is commonly used for lifting purpose when you need strength, durability and resistance to abrasion to handle loads. Wire rope consists of a number of small individual wires that are turned into strands, the strands are then twisted together to form solid rope. Wire ropes slings have long been the standard when it comes to overhead lifting and material handling.

And if we talk about Lifting & Moving loads then wire rope slings plays significant role to handle bending stress as it is too flexible in nature. Areas where wire rope slings are most popular-
  •         Construction Industries
  •          Manufacturing Industries
  •      Automotive Industries
  •     Oil & gas etc

In these areas, variety of heavy loads and rugged conditions exist and they prefer to utilize wire rope slings because wire rope constructed of various grades of steel making it resistant to elements such as moisture, heat UV, and such chemicals. Wire rope slings can be assembled in a variety of configurations and sizes for nearly any lifting applications. The twisted strands of heavy duty wires are extremely durable and they create high tensile strength, so we often prefer wire rope sling in these industries.
