The Grade 100 chain tensioners TWN 1454 with toggle are used as tensioning elements in lashing chains. The chain tensioners can also be used in chain slings for stepless adjustment of strand lengths when lifting loads. These chain tensioners have a particularly large lift. The chain tensioners with toggle and trapezoidal thread achieve a high pretensioning force with little force impact. This property is of fundamental importance when lashing down, as the level of the pretensioning force contributes to load securing.
The manufacturing and testing requirements are based on the ISO 8539 and DIN EN 1677-1, under consideration of Grade 100 lashing capacities.
