All about Veder-Lok ® 

Slings Veder-Lok Flemish eye steel ferrule-secured termination

Many slings are produced with Veder-Lok ® (a Flemish eye steel ferrule-secured termination).
This way of splicing gained popularity in the offshore and construction industries for its safety. Hendrik Veder Group is able to produce Veder-Lok ® terminations for steel wire ropes ranging from 6 to 128 mm ø.

Safe method

The most common types of ferrules are: the Flemish eye (figure 1) and the turn back loop (figure 2). The Flemish eye steel ferrule-secured termination is the preferred method, because this principle is based on splicing and securing instead of clamping (as used in a turn back loop). This ensures that, if the ferrule fails, the loop will remain intact. Another advantage is that they are covered by the swaged steel ferrule, so it can not cause injuries.

Breaking Force

The Veder-Lok ® eye will reduce the minimum breaking force of the wire rope by 10% (according to EN 13314-1). The construction ensures equal distribution of the load, because the pull is directly along the centerline. A solid bond around the splice is formed by the ferrule, which gives the termination maximum efficiency.

How it is made

The eye termination is made where the rope end is split into two parts of each other, which are symmetrical to the rope axis. The tails of the beaches are distributed around the main body of the rope. They are fixed in this position by means of a ferrule. The soft eye can be provided with various types or thimbles.

An alternative for Veder-Lok ® is the carbon steel turn back ferrule. More information about this can be read in our next article.
