Lashing strap storage system for truck bodies

For safety reasons, the road traffic regulations require that loads be secured or lashed to prevent them from moving or slipping. For this reason, newly delivered trucks are now fitted with lashing eyes that can be used to securely lash the goods to the floor of the truck using standard lashing straps with turnbuckles.

i-

The disadvantage is that the strap has to be hooked into one side, the strap has to be guided over the goods and then lashed and tightened on the other side using the turnbuckle that belongs to the lashing strap. This can be necessary eight to ten times for a normal truck, depending on the size of the loading area.

The drivers have to open both the tarpaulins and the awnings so that they can throw the strap from one side to the other. Or they have to climb onto the truck and put the straps over the containers for each row of new containers. This is dangerous, inconvenient and time-consuming!

The object of the invention is to propose a lashing strap holding system that is easier to use.

The object is achieved by the invention explained in more detail below using an embodiment.

Figure 1 shows a sketch of a cross-section of a truck body with a lashing strap in a relaxed, ready state and Figure 2 shows the same lashing strap in a tensioned state with goods lashed.

In the relaxed position shown in Figure 1, the lashing strap 9 is retracted by spring retractors 1 la and 1 lb, onto which the retrieval line 17 is rolled, to the outer contours of the structure not required for loading, for example into the tarpaulin frame 4.
The cargo space therefore remains free for loading.

The lashing strap tensioner 10 and the strap guide roller 12 with the strap 9 located therein are pulled up to the retrieval elements 11 a and 11 b. The retrieval weight 14 rolls over the roller guide attached to the retrieval element 11 b and tightens the strap so that there is freedom of movement for the load. To tighten it after loading, the lashing strap tensioner 10 is then pulled down again, if necessary with the auxiliary hook 16, and hooked into the lashing eye 8. Depending on the load volume, the lashing strap 9 is then pulled loosely through the lashing strap tensioner 10 and then lashed by operating the lashing strap tensioner 10.

The spring line 17 is also pulled out of the retrieval elements 11 a and 11 b and must have a retrieval force which, when the strap 9 is released, then pulls it back into the ready position when the lashing strap turnbuckle 10 is released.

The belt itself is held and guided by a belt guide roller 12 which is attached to the end of the spring line of the element 11 b.

The lashing strap tensioner 10 is pulled to the retrieval element 11a with the line 17 attached to it. The strap is then back in the resting state. The system in Figure 2 shows the tensioned state.

.. The method described above can be used for all vehicles with a tarpaulin and bows - regardless of whether sliding doors, sliding tarpaulins or normal brackets are used. At a minimum, retrieval devices are required which are fixed in the upper area under the tarpaulin or can be moved lengthways to the vehicle. Instead of the indicated return spring box 11a, 11b, this retrieval can also be carried out using long springs which are attached under the roof, via rollers or via counterweights which are guided via a cable from the front bracket to the individual lashing points. Retrieval by hand is also possible using cables which can be attached or detached to the front bracket or to one of the spars.

The roller guide 12 at the end of the return element 11 a, 11 b must be adapted to the belt 9 so that it can run easily in it.
The above example is shown for a common loading from one side.

-5-

When loading from both sides, both vehicle brackets 2,3 are opened. Depending on the loading side, the lashing strap tensioner 10 or the opposite lashing strap hook 15 must of course be loosened and pulled up. Any loosely hanging

Lashing strap ends can be pulled to the side with a hook 16, which can also be used to retrieve the high-hanging lashing strap tensioner 10. Of course, the retrieval elements 11 a, 11 b can also be arranged so that they can be moved in the longitudinal direction and thus removed from the loading area.

A lashing strap tensioner can also be attached to each side for two-sided loading. In this case, a strap guide roller 12 is used on each side, which is attached to the respective retrieval line 17.

The return weight is thereby made unnecessary and is replaced by the weight of the respective lashing strap tensioner 10.

Claims (5)

1. A lashing system, in particular for truck bodies, with at least one lashing strap for securing the load, wherein the lashing strap is retracted into a ready position which frees up the loading space during the loading state and can be operated from a single point to tighten the load. 2. A holding system according to claim 1, characterized in that at least one lashing strap is pulled into the holding position by means of spring force. 3. A holding system according to claim 2, characterized in that retrieval elements for at least one lashing strap are each attached to the upper outer contours of the truck body in a fixed manner or so as to be displaceable in the longitudinal direction. 4. A holding system according to claim 3, characterized in that at least one lashing strap is guided in corresponding roller guides attached to the retrieval element. 5. A holding system according to one of the preceding claims 1-4, characterized in that the at least one lashing strap is provided at at least one free end with a loop into which a hook is hooked in the holding position, with the aid of which the at least one lashing strap is pulled into a tensioning position.
