Load Securing Calculator: How Many Lashing Straps? (EN 12195-1)

Load securing is calculated per direction: the restraint must hold 0.8 of the cargo weight forwards and 0.5 sideways and rearwards under EN 12195-1 and Directive 2014/47/EU (in Great Britain the DVSA asks for the full weight forwards); friction carries μ × weight and blocking plus lashings carry the rest. For top-over lashing only the pre-tension (STF) counts: one 400 daN strap at 80° secures about 6,571 kg sideways at μ 0.45 but only 826 kg forwards, which is why loads go against the headboard. In Logistivo the load record holds weight, loading metres, stackability and vehicle type, and the driver app can record the trailer handover with photos.

Frequently asked questions

What is the calculator's result meant for?

For planning: it uses the EN 12195-1 formulas as applied in the EU guidelines and estimates the securing of one rigid load block. The duties of consignor, operator and driver remain; special cases need a full calculation to the standard or a test.

Which accelerations apply to HGVs?

In the EU: 0.8 of the load weight forwards, 0.5 sideways and 0.5 rearwards, with 0.6 sideways where the load may tip (Directive 2014/47/EU, Annex III; EN 12195-1). The DVSA guide for Great Britain asks for the entire weight forwards.

Can I add the headboard and the lashings together?

Yes. Under EN 12195-1 blocking and lashing capacity may be added; the calculator converts both into secured mass and adds them.

Why do my straps hold a lot sideways but hardly anything forwards?

Because 0.8 acts forwards instead of 0.5 and the safety factor is 1.25 instead of 1.1. At μ 0.45 a strap with STF 400 daN secures 6,571 kg sideways but only 826 kg forwards.

What friction coefficient does the DVSA accept?

For your own calculation: a tested value for that load and vehicle, the certified value of a high-friction surface, or 0.2 in all other cases. Select the GB (DVSA) rule in the calculator to apply this.

How does Logistivo help with load securing?

Logistivo keeps the figures you calculate with here – weight, loading metres, stackability and vehicle type – on the load, shipper and carrier agree the load plan in the load's own chat, and with equipment inspections switched on the driver app records the trailer handover with photos.

Can I show in Logistivo what condition the trailer was in at pickup?

Yes, when equipment inspections are switched on for the company: the driver photographs the trailer at pickup and drop-off, every photo with capture time and GPS position, and AI compares consecutive checks and flags new damage.
