A-strap, what can it do?

Cargo securing for the economically minded

This is post number 29 in a series of cargo securing advice and useful hints. These are meant for people who think economically. They do not like to waste time, muscle power, risk their health or pay fines.

On some markets there is in use a method where independent semi-vertical straps (most commonly known as ‘A’-Straps or Black Straps) are attached between a T bar or rave on both sides of the vehicle and run to individual tracks installed in each side of the trailer or truck roof so these straps are not inter-connected across the width of the vehicle! This method does not over-strap the load so it has no frictional effect on the cargo at all and is not lashing anything as the straps cannot be tightened over the cargo, they are just between the floor and the roof. Therefore, the cargo is wholly unsecured and can still slide and move about. The only possible effect ‘A’-straps offer is a small amount support to the cargo side-ways when the cargo already has moved and leans on the straps. The force against the ´A´-straps must be VERY LOW indeed as locking device can slip. ‘A’-straps will not have any effect on controlling the strong dynamic forces that can quickly build up when a load has started to move. Usually in trailer manufacturing there are no demands about the roof to be used as part of cargo securing and therefore it is unlikely that the trailer maker has dimensioned the roof to tolerate anything from the ‘A’-straps.  Exactly the same effect can be experienced if a Code-XL trailer is used without cargo securing. If the cargo moves, it will stress the roof and wall/curtain construction.

Drive safely,
