vehicle recovery and transportation

preface

Securing of cars and vans up to 4 tons permissible maximum weight is explained at VDI guideline 2700 page 8. The following instructions should be considered by the use of SHZ car lashings. They are in accordance with the guideline named above.
There is a significant difference between the securing of the spring mounted mass and the wheels (unsprunged mass).

securing of the spring mounted mass

This securing method could be realized as direct or diagonal lashing.

premises:

• anchorage points at the car body

conclusion:

This method is often used to secure vehicles at RoRo-ships. Thereby should be avoided that the ship gets instable by slipping cars. During maritime transport lashing straps should be tight but without an high standard tension force. Furthermore this method is often used for load securing of construction and agricultural machinery. To transport cars and light-duty commercial vehicles on roads it's unusual to secure the spring mounted mass.

securing of the unsprunged mass

The load securing of cars at vehicle transporters is often realized as a combination of force and form closure. Form closure could be achieved with wheel brackets and force closure with specific lashing straps. Following a selection of appropriate lashings:

[wheel lashings]

premises:

• wheel brackets with a minimal height of 1/6 wheel diameter
• lashing straps with sliding inhibitors
• punched load floor to fix the lashings

procedure of securing cars:

• pull the handbrake, engag 1st gear and lock steering wheel
• anchor wheel brackets at required position
• fix first hook in the floor so that the lashing runs perpendicular up
• pull the lashing across the wheel and fix the second hook also perpendicular in the floor
• fix the third hook, loop around outwards and tight the lashing

safety instructions:

• Strain the hooks only with drag and not with bending forces.
• Don't use damaged lashings.
• Don't twist lashing straps.

According to VDI guideline Page 8 the following points has to be observed by securing cars at vehicle transorters.

Most rescue vessels have a closed load floor in order that no liquids could drip on the road. That's why the use of three-point-lashings isn't possible. We recommend direct lashing at all four wheels with our specific lashings ZCRS .
