Crane Wire Rope

Most cranes come with a recommended type of wire rope to use on the different functional components. Proper application of the wire rope to each crane function is necessary to extract best performance, prevent accident, and avoid damage to the equipment.

For wire rope maintenance, we use lubricants.

End Terminations

Crane wire ropes are usually fabricated with mechanically spliced soft eye, or fitted with thimble or socket.

Fittings
Thimble

A standard or solid thimble termination gives better resistance against abrasion and crushing at the eye. Our standard steel thimbles are made to either BS 464, FF-T-276b Type III (G414) or JIS B2802 (Type A) specifications. Our solid thimbles are built to JIS B2802, JIS F3403 or DIN 3091 standard.

Socket

For crane wire ropes, many different types of sockets are used such as open and closed spelter sockets, open and closed swage sockets, wedge socket and Nemag rope pear socket.

A wedge socket termination reduces the wire rope efficiency to 80%, but the wedge socket remains a popular choice because it is easy to install and can be attached after the wire rope is reeved.

Spelter sockets and Nemag rope pear sockets are secured to the rope with Wirelock socketing agent, and the rope retains its full strength.

The Nemag rope pear socket when paired with the Nemag quick release link forms an unbreakable connection between two ropes. Together, they enable quick and straightforward coupling and uncoupling of grabs on cranes. Made from high grade austenitic manganese steel, these Nemag fittings generally outlast the wire rope.
