wire rope load quotation

Rated load based on pin diameter no larger than one half the natural eye length or not less than the nominal sling diameter. Basket hitch capacity based on minimum D/d ratio of 25/1. For choker hitch, the angle of choke shall be 120 degrees or greater. For sling angles other than those shown, use the rated load for the next lower angle or a qualified person shall calculate the rated load. Horizontal sling angles of less than 30 degrees are not recommended. The capacity of a bridle at a 30 degree horizontal is same as single vertical leg.

There are different ways of creating wire ropes, and each produces a rope that offers unique stress and rotational qualities suited to specific tasks. For most tasks, the two primary types of rope in use are stranded and spiral wire ropes.

Stranded wire ropes—steel strands wound in one or more layers around a core made of synthetic material, a wire strand, or a wire rope—secure loads as wire rope slings or running ropes because, in addition to being stressed by tensile forces, they take stress by being bent over the items that they are securing.

The three types of spiral wire rope, steel strands wound in opposing helical layers to make them nearly non-rotating, offer their own positives and negatives. Open spiral wire rope, made only from round wires, is suited to lighter applications. The half- and full-locked variants have a round wire core surrounded by profile strands that protect the rope and keep it lubricated. Given these qualities, spiral ropes are generally used as stationary ropes and stay ropes as they are good with both static and fluctuating tensile stresses. Full-locked ropes also serve as track ropes for cable cars, ski-lifts, cranes, and similar machines as they experience an increase in their free-bending radius when the tensile force increases, decreasing the bending stresses on the rope. As the roller force increases, however, that tensile force, along with the free-bending radius of the rope, decreases.

Understand that most of the people out from the industry always face the problem of having no idea with the terms of wire rope when receiving quotation. In this update, we will explain in the most simple way and hopefully it is applicable to anyone.

6X36 = Construction of wire rope (There are quite a lot different constructions available for different application for example like, 6X25, 6X29, 6X31, 4X39, 19X7, 8X26 etc.)

RHOL = Right hand ordinary lay, it is the wire lay direction and very important to select the right direction of wire when dealing with multi-reeving, crane and hoist application.

EIPS (1960) = Extra improved plow steel and 1960 stands for the tensile strength 1960N/mm2. The figure is telling you the grade of wire rope, lower or higher tensile strength will result in different breaking strength.

UNGALVD = Ungalvanized, the surface finishing of wire rope. Galvanized and Ungalvanized are the basic surface finishing selection with different grade of lubrication.

MECH SPLICED = Mechanical splicing is the process of using hydraulic pressure to press the aluminum sleeve or metal sleeve and a loop is formed. This phrase is always telling you the terminal of both end wire rope. It can be plain, socketed, fuse tapered or eye formed.

Wire rope could have a lot of variation upon the application which I will cover in the next update. The essay above is good enough to tell the basic and hope it helps for procurement department while dealing with steel wire rope. Last but not least, selecting the right wire rope is crucial to your company"s long term expenditure and safety purposes. Do not take the risk because of cheap.

The load which a new wire rope may handle under given operating conditions and at an assumed design factor. A design factor of five is chosen most frequently for wire rope. (Operating loads not to exceed 20% of catalog breaking strength). Operating loads may have to be reduced when life, limb, or valuable property are at risk, or other than new wire rope is used. A design factor of 10 is usually chosen when wire rope is used to carry personnel. (Operating loads not to exceed 10% of catalog breaking strength). Responsibility for choosing a design factor with the user.

Rope sockets, thimbles, sleeves, hooks, links, shackles, sheaves, blocks, etc., must match in size, materials and strength, to provide adequate safety protection. Proper installation is crucial for maximum efficiency and safety.
