Straps: flexible and easy to use
Straps are the most common way of cargo securing. A method often applied is lashing. The cargo will be pressed on the floor due to the pretension force. This will increase the friction which will prevent the cargo from sliding.

Methods of securing
The choice for a certain method of securing depends on the kind of cargo and the bodywork.

The lashing capacity for straps is indicated in daN.

• for light duty applications

• low pre-tension

• tensioning by cam

• Standard tension force upto ± 200 daN.

• for heavy duty applications

• high standard tension force

Top over lashing is a common way to restraint cargo. The cargo is kept in place due to the optimum balance between tension.....and friction.

Lashing
Top over lashing is a form of lashing that is applied over the goods in order to keep the cargo from tipping and sliding. Top over lashing is used to press a cargo section towards the platform bed so that the friction increases. The use of anti-slide mats is recommended to decrease the number of lashings.

Lashing
Lashing is the principle to increase friction between cargo and cargo floor, for example by using straps to press cargo elements against the floor.

Blocking
Blocking means that the cargo is stowed to lie flush against fixed structures and fixtures on the load carrier. These may be headboards, sideboards, sidewalls or stanchions. If the cargo is tightly fit against blocking devices and all gaps are filled, the cargo will be secured by the vehicle structure.

The calculation example shows that more pre-tension force can be achieved with long lever ratchets then standard ratchets. As a result, the number of required straps can decrease significantly.

The combination of lashing and blocking is also possible. For example when cargo is positioned directly against the front bulkhead, straps can be used to secure the cargo from sliding sideways. Cargo must always be secured in all directions. When construction elements of the vehicle such as bulkhead, stanchions and sideboards are suitable for cargo securing, the combination of blocking and lashing is recommended.

The standard DIN EN 283 and DIN EN 12642 draws a distinction between swap bodies and standard bodies ( code L) on one side and reïnforced bodies ( code XL) on the other side. The maximum capacity of the bodies is:
