DoRa-ratchet load tensioner.

The longest tensioning path despite its small design!

You can use the DoRa ratchet load tensioner like any other ratchet load tensioner:

Hook the end fittings into the lashing-points
Tighten the lashing chains by hand
Hook into the shortening elements provided
Tensioning using the tensioning element
Re-tensioning the lashing chains loosened during the journey due to a possible load offset, as prescribed for all lashing equipment

Your advantages with the DoRa.

Less force required due to extra-long tensioning travel

Use in confined spaces due to compact design

Easy re-clamping due to tensioning path "reserves"

Time saving due to extremely long tensioning stroke

Save strength!

Due to less tightening of the chains when hooking in

Small design!

Can also be used in tight spaces

Save time!

Thanks to the "tensioning path reserve", the lashing chain does not have to be completely re-tensioned when re-tensioning

Longer service life!

Thanks to innovative & completely new visual marking & thread overtightening protection

The highlight: a new design principle.

The secret of the unique relationship between clamping travel and overall length lies in the design of the DoRa ratchet load tensioner. Instead of two identically designed threaded spindles, which are turned "against each other" in the closed clamp, the DoRa ratchet load tensioner has two different clamping spindles.

One spindle has a larger diameter and is hollow on the inside, the other has a smaller diameter and fits into the cavity of the larger spindle. When closed (retracted), one spindle is screwed into the other.

Extremely long clamping distance despite short overall length.

DoRa ratchet tensioner vs standard tensioner

The new way to secure unscrewing

Visual marking

Easy recognition of the maximum unscrewing length by milling on the threaded rods

Thread overtightening protection

If you continue to turn despite the marking, the second mechanism engages. The threaded rod is freely rotated. However, the tensioner is then not broken. You can simply screw the threaded rod back into the nut & tension normally

Your advantage with the DoRa

No more discarding due to destroyed unscrewing locks
