DoMess 3

DoMess 3 – mobile pretension force indicator

Your benefits:

  • DoMess 3 is not permanently installed. It is placed loosely on the ratchet strap(s )
  • More safety, as you can read how much preload force is in the system, thus control of all preload forces
  • Cost-saving, as you need fewer ratchet straps (see page 108)
  • Time savings, as fewer ratchet straps need to be applied
  • Both the clamping side and the opposite side can be controlled with one device

Complies with the requirements of DIN EN 12195-2.


4 seconds for your safety:

It takes only 4 seconds to determine the pretensioning force: Place the device on the tensioned lashing strap, swivel the lever, read off the pretensioning force – done!

DoMulti 5000 with DoMess 2


The DoMulti long lever tension ratchet is also available with the DoMess 2 pretension force indicator . As standard, DoMess 2 is permanently connected to the ratchet, allowing easy reading of the pretensioning force (STF) of the lashing strap in 250 daN increments up to 1000 daN. 


Please note: Only the pretensioning force value verified with a pretensioning force measuring device (e.g. DoMess 1-3) and exceeding the STF specification in the label may be included in the calculation of the number of lashings.

With the DoMulti long-lever tension ratchet, pretensioning forces of up to 1000 daN can be achieved.
DoMess 2 can optionally also be loosely mounted on the belt webbing and can thus also indicate the pre-tensioning force applied to the belt on the side opposite the tensioning element (ratchet).
