SpanSet Apps

Fall height calculator

The app provides information on whether the lintel height is sufficient for various application scenarios. Just click on the lanyard used, define the work situation with a few fingertips and let the application calculate whether the person will be safely caught in the event of a fall.

The fitter or worker can easily make the calculation using a smartphone and then knows how effective his protective equipment is. This information on the display alone can save lives.

Document risk assessment by e-mail
The lintel height calculator app is also a valuable and sometimes labour law relevant support for foremen, site managers and other responsible persons. They can literally hold the result of their risk assessment under the individual worker's nose and either release the concrete situation or demand changes - such as selecting a different anchor point. In addition, the SpanSet-App offers a documentation function that should not be underestimated. One can send the results of the calculation to oneself or to another recipient by e-mail. 

The free offer applies exclusively to the SpanSet connectors SP140 and DSL2.

Available languages: German, English, Finnish, Greek, Italian, Lithuanian, Dutch, Norwegian (Bokmål), Polish, Portuguese, Spanish, Czech, Turkish, Hungarian



The app shows you what you need to look out for during the regular visual inspection of safety harnesses, lanyards and hooks.

When downloading, please select the operating system for which you require the app.

Lashing calculator

The useful tool based on the tried-and-tested SpanSet lashing force controller offers a clear and easy-to-understand user interface, making calculating the required lashing straps child's play.

The number of lashing straps required for a given pre-tensioning force (STF) is displayed directly in just a few steps using the slider or direct input of the coefficients of sliding friction, angle of inclination and pre-tensioning forces as well as the acceleration in the direction of travel and the K-factor.

The angle of inclination can even be calculated or displayed by the position sensors in the smartphone. The load securing values can be calculated according to the guidelines of VDI 2700 ff. and/or DIN EN 12195. The additional option of documenting the load distribution plan makes the lashing force calculator a mobile added value in load securing.

The free app is available on Google Play in the App Store in German, English, French, Italian and Dutch.
