The aluminium ferrule UM (Ultragrip™) are made from a special designed profile. The UM ferrule corresponds to EN 13411-3, the European standard (FSET) and also the Japanese standard for turnback ferrule or ferrule secured eye termination. The ferrules are produced from seamfree extrucions which are extruded seamlessly over mandrel and the aluminium alloy is EN AW-5051A according to EN 573-3.
The UM ferrule and the K ferrule can be used in basic applications, with bright or galvanized single layer steel wire ropes with round strands up to fill factor 0,60 and grade 1960. The types of rope lay shall be Ordinary or Lang lay. For fibre core wire ropes larger than 60 mm the maximum rope grade is 1770. Wire ropes shall conform to EN 12385-4 and 5.
TO BE NOTED
The UM ferrule and the K ferrule become smaller in diameter after pressing than the T ferrule. For economic reasons, the UM ferrule can be used as an alternative to the T ferrule at wire rope grades, up to and including 1960. The UM ferrule and the K ferrule are available from stock in sizes from 10-90.
