Torpedo Crane Rope End Buttons

Posted on:

Button spelter sockets come in seemingly endless dimensions and configurations. Nearly every crane manufacturer is using a different type and sized button making the logistics impossible to keep every type of button for every type of manufacturer for every rope size available at any time.

Also, many crane users have adopted other ‘after market’ systems which use different hardware than the crane OEM.

We at Unirope designed a universal type of round Torpedo Button which can be configured to fit most “baskets” or “pouches” in the field.

These Torpedo Buttons are made 100% in our own in-house machine shop using highest quality tool steels which are heat treated and hardened to over 45RC to ensure durability and strength.

Unirope Torpedo Buttons comply to EN 13411-4 and, in addition, have been Fatigue Type Tested to 75,000 cycles.

We design these buttons, we make these buttons, we install these buttons, we proof test these buttons.

Becket Loops

Posted on:

Becket Loops are swaged onto the rope end for installation purposes only. When installing a new wire rope a becket loop allows to connect the old rope to the new rope without the aid of cable grips. The diameter of UNI-LOC® Becket Loop Sleeves is slightly larger than the rope diameter itself.

Larger or smaller loop dimensions upon request.

Closed Spelter Socket

Posted on:

If socketing is properly applied ropes have the highest breaking strength of all end-termination methods. Socketing is done with WIRELOCK resin compound. Sockets fit Standard rope – and most Python® wire rope constructions. Ask for details.

Note: Do not attempt socketing yourself unless person is specially trained and qualified.

Loop Back SOLID Thimble Splice (S 412 Thimble)

Posted on:

This splice is fabricated by forming a loop eye and pressing an aluminum sleeve over both rope parts. The strength depends 100% upon the integrity of the pressed sleeve.

Unirope fabricates these splices according to the strict European standard EN 13411, using original specification sleeves and dies as specified in that standard.

 

With Crosby Cast Solid Thimble and EN 13411-3 Aluminum Sleeve. Thimbles to DIN 3091.

Solid Thimbles are used where the sling (or rope) is connected to a straight pin. This makes an excellent permanent installation. Within certain limitations we can increase or bush the bore hole, or we can mill down dimension ‘H’ to fit a narrower slot. These thimbles are mainly used on crane ropes.

Unirope fabricates these splices according to the strict European standard EN 13411, using original specification sleeves and dies as specified in that standard.

This method is used for 8-, 9-, and 10 strand as well as non-rotating rope types (19×7, 19×19, 24×7, 34×7), and when Tri-Flex® and Gator-Flex® slings are requested with Thimbles at the ends.
