The Grade 100 ratchet tensioners KH with clevis connenction TWN 1455 are used as tensioning elements in lashing chains.
The ratchet tensioners can also be used in chain slings for stepless adjustment of strand lengths when lifting loads. The ratched tensioners have a particularly large lift.
The ratched tensioners with 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 DIN EN 1677-1, under consideration of Grade 100 lashing capacities.
