Cargo securing calculator (EN 12195-1)

Describe the cargo, the floor and the straps; the tool returns the lashings needed in each direction against sliding and, for one symmetric block, against tipping, under EN 12195-1:2010. Road coefficients; everything runs in your browser.

Cargo, floor and straps

EN 12195-1:2010

Transport modeTables 2, 3 and 4 of EN 12195-1:2010. Sea areas as the standard defines them: A, the Baltic; B, west of area A up to Kristiansand–Montrose and Brest–Land’s End plus the whole Mediterranean; C, unrestricted. The CTU Code puts the Mediterranean in area A; this tool follows EN 12195-1.Cargo masskg

Lashing method

Surfaces in contact (Annex B)Dirty, oily or icy surfaces: µ = 0.2

Vertical angle α°Between 75° and 90° the strap works well; below 30° it does almost nothing.STF per strapdaNThe standard tension force on the label (EN 12195-2), not the LC. A common 50 mm ratchet gives about 250–500 daN.

Check tipping of one block

One symmetric block: length in the direction of travel, width and height.

Per direction

	Sliding	Tipping	lashings
Forward (0.8 g)	8	no risk	8
Rearward (0.5 g)	1	no risk	2
Sideways (0.5 g · tipping 0.6 g)	1	no risk	2

A strap’s pretension must not exceed 50 % of its LC. Always round up.

What it does and does not do

Road acceleration coefficients (Table 2): 0.8 g forward, 0.5 g rearward and sideways, 0.6 g for sideways tipping, 1.0 g vertical. Rail and sea are not included.
Friction values are those of Annex B (normative), valid dry and wet with clean, ice-free surfaces.
Tie-down lashing works only through friction: as µ tends to zero, no number of straps is enough.
Tipping is computed for one symmetric block with top-over lashing; loop lashing, spring lashing and direct lashing against tipping are not included.

Indicative calculation under EN 12195-1:2010 for road transport. Real securing depends on the goods, the vehicle, the state of the straps and the national rules that apply; the driver and the loader are responsible. Check the text of the standard and the official guides before deciding.
