Rule of thumb for none-self-propelled cargo below 10 mt

Top-over Lashing Instruction

When cargo does not have any lashing points, top-over lashing (friction securing) can be used. Top-over lashing only increasing the friction so it should not be used on cargo weight above 10 MT.

When using the table for top-over lashing the angle between the lashing and horizontal surface is of great importance. The table is valid for an angle between 75° and 90°. If the angle is between 30° to 75° twice the number of lashings is needed (alternatively the table values are halved). If the angle is less than 30°, another cargo securing method should be used, such as half-loop (loop) lashing.

Top–over lashings should be placed symmetrically on the cargo.
