GWS® STF-DEFI lashing strap©In the tie-down lashing method with lashing straps manufactured in accordance with the European standard DIN EN 12195-2, the user achieves the pre-tensioning force STF shown on the label of the fixed end with a standardised manual force SHF 50 daN.However, due to the design of the ratchet and depending on the working position and the individual force applied by the user, the actual manual force applied deviates from the standard force of 50 daN. This means that the desired pre-tensioning force STF is either exceeded or not reached. This securing method exerts considerable pressure on the load, particularly when lashing down. Not every load can withstand this pressure from the tensioned lashing straps during transport. If the load collapses, it will probably be damaged and the load securing method will no longer have sufficient effect. This in turn can lead to reports or, in the worst case, to serious accidents. With the GWS® STF-DEFI lashing strap©, we offer you an ergonomic way of achieving the calculated, necessary pre-tensioning forces without exceeding them. Your advantages:With the GWS® STF-DEFI lashing strap©, we offer you maximum protection for pressure-sensitive loads as well as the necessary transport safety. In accordance with EN 12195-1 (‘For practical reasons, e.g. due to the settling behaviour of the load, re-tensioning is recommended after a short journey.’) and VDI 2700 (‘An applied pre-tensioning force of lashing equipment must be maintained during transport or, if necessary, re-tensioned.’), defined re-tensioning during transport is possible without additional pre-tensioning measuring devices. Ergonomic working with the tension gear ratchetEasier work thanks to the lever arm lengthTechnical support and annual, documented inspection by a specialised company Technical data: GWS® STF-DEFI lashing strap - Two-part system - manufactured and tested in accordance with EN 12195-1 - Ergo gear ratchet - Fixed end 0.7 m + loose end 3.3 m - Fixed end and loose end equipped with pointed hooks - Webbing width 75 mm - Strap colour: orange - Lashing capacity LC 5,000 daN single direct - Pre-tensioning force/Standard Tension Force STF - customised to specification, factory-set between  50daN and a maximum of 500 daN (standard value), tolerance ± 50 daN  Other versions of GWS® STF-DEFI lashing straps© in one-piece or two-piece design with different end fittings, webbing widths, LC values and desired STF values are available on request. 

The manual force (SHF) applied by the user when lashing down can neither be estimated nor tested. The tensioning elements of the lashing straps are therefore tensioned by feel, but sometimes with the full force of the user. This can result in serious damage to the user's back and spine (loss of health, slipped discs, etc.).Often, unsuitable tools are used to tighten the ratchet, resulting in parts of the clamping element becoming deformed and therefore unusable.To avoid these stresses, there is now an extension that is adjusted to the manual force (SHF, standard ratchet 50 daN) with a holder for the clamping lever of the ratchet (clamping element) that emits a tactile and audible signal when the manual force is reached. The main advantages of the device are that it enables the normal manual force (SHF) to be reached in a controlled manner, uniform and controlled tensioning of the lashing straps and a significant reduction in labour costs of 65 - 70%.  The GWS®-Guspako® belt tensioning controller is a patented work aid that makes everyday work much easier for you and your employees.
