Wire Rope

DCL Mooring and Rigging is a leading manufacturer, fabricator, and seller of all different types of wire rope. In the informational articles below, you can find tons of information to help you make informed decisions regarding the type of wire rope to select, based on the different construction types, wire rope finshes, grades, and lays. Wire rope is identified by its construction, or the number of strands per rope and number of wires in each strand. For example, the construction 6×25 denotes a 6-strand rope, with each strand having 25 wires. Constructions having similar weights and breaking strengths are grouped into wire rope classifications, such as the 6×19 and 6×37 classes. Wire rope finish refers to whether the rope has a protective coating or not. The term bright refers to a wire rope manufactured wit hno protective coating or finsih other than lubricant. Some applications do require more corrosion protection than lubricant can provide. In these instances, a galvanized finish is provided. The different types of wire grade include Extra Improved Plow (EIP), which is now standard for all wire rope. Another type is  Extra Extra Improved Plow (EEIP) steel, which is used where high breaking strength is required. It typically provides a breaking strength a minimum of 10% higher than EIP.  The third wire grade is Royal Purple Plus, which provides a breaking strength 35% higher than Purple Plus, and is available in Wirerope Works’ TRIPLE-PAC hoist rope. It is the grade of wire which determines the nominal breaking strength for each diameter and cosntruction. Wire rope lay is another important factor when choosing the right type of wire rope, lay is the helix or spiral of the wires and strands in a rope. There are 4 different types of lays, which are right regular lay, left regular lay, right lang lay, and left lang lay. The last component to consider is preformed wire rope. Preformed wire rope means that the wires and stands have been preset during manufacture into the permanent helical form they take in the completed rope. Unless otherwise specified, Wire Rope is typically furnished preformed. Preformed wire rope has the difinte characteristics which are advantageous on most wire rope applications. Preforming greatly reduces internal stresses, eases rope handling, and gives more equal distribution of load on the wires and strands. Preformed rope runs smoother and spools more uniformly on adrum than non-preformed, has greater flexibility and gives longer service life in bending. They tend to remain in position after breaking. This reduces the tendency for them to protrude and damage adjacent wires. Because the wires do not protrude, we strongly suggest greater care and more thorough inspection to detect broken wires in a preformed wire rope.
