Description

ALVEOLAR OR SEMI-COMPOSITE LOCKING COMPENSATOR
ALVEOLAR WITH DIFFERENTIAL TIMING AND MOORING
INCORPORATED SELF-SHOCK ABSORBER.

The present invention relates to a lashing compensator sized to the standards of the ISO system (International Standard Organization), or to other measurement systems and standards, forming a receptacle composed of cells or semi-cells, rigid or semi- rigid composite metal or similar material, with variable damping, intended to ensure the safe connection of batches of naked goods or packaged with transport equipment, and to ensure optimized wedging and mooring of batches of naked goods or conditioned in packages, in all lateral, longitudinal and vertical directions in all handling and maritime and land transport operations and incidents or accidents likely to occur during them.

Such a tie-down compensator will be used for the maritime or terrestrial transport of batches of goods naked or packaged in packaging and more particularly fragile, dangerous or high value, solid, fluid, or gaseous goods.

Dangerous goods are defined in particular as such by the following regulations:
-Regulations for the Transport of Dangerous Xatières from April 15
1945., - Recommendations of the UN (United Nations Office),
Such a tie-down compensator is designed to receive all types of goods and all types of packaging such as glass, metal, stoneware, plastic, aluminum, textile, paper or other containers whatever their mode of opening, their content, the degree of risk thereof including radioactive materials.

 These goods may be of a density less than, equal to or greater than i.

The stowage of batches of naked or conditioned goods is traditionally carried out through:
- With a simple mooring, this device has shortcomings in particular in the event of an accident or incident, in particular in the event of a frontal impact because the straps are generally arranged transversely and not longitudinally, only holding the goods imperfectly,
- Wooden blocks fixed by nailing on the floor of the transport vehicles. The implementation of this technique is long, expensive and random. In general, wedging can only be done before the removal of batches of naked or conditioned goods. The wooden blocks are not reusable. They cannot guarantee compliance with the
Regulations for the Transport of Dangerous Goods and incur incalculable risks to users and the public. In the case of the transport of certain radioactive materials, the floor of transport equipment is metallic and does not allow their use.

 -Devices anchored to the chassis of transport vehicles and inserted into the floor of these vehicles during their construction (anchor rails). This system is expensive and cannot be generalized. In addition, it makes specialized transport equipment. I1 is attached to this transport vehicle and is therefore not versatile. In addition, this device does not adapt well to the configuration of certain naked or conditioned goods and does not have any lashing in all directions.

The lashing compensator according to the invention overcomes these drawbacks.

The lashing compensator seen from above is schematically in the form of an "equal sign", an I, or a window with one, two, or more tiles.

The lashing compensator is made up of 3 main sub-assemblies:
-in all cases of 2 elements of variable resistance at the end of the transport units in the direction of travel, ensuring the safe securing mainly in the longitudinal direction of batches of goods naked or conditioned.

In addition, these elements may receive at their end on the side or at the end of the accessories elements described below. to ensure the connection of the lashing compensator with transport equipment.

According to the variants, these 2 elements may be supplemented by a quantity defined according to the needs of possibly parallel adjustable parallel elements.

-Zero, one, two, three, or more fixed or adjustable longitudinal elements, of variable resistance, perpendicular to those above ensuring secure securing, mainly in the lateral direction, of batches of naked or conditioned goods.
In addition, these elements may receive accessory elements described below at their end and / or in an intermediate position allowing the connection of the lashing compensator with the transport vehicle.

 -Four or more elements fixed on one of the sub-assemblies or the two stated above allowing the connection of the lashing compensator itself safely with the transport vehicles.

for these latter elements it may be;
-Either fixing locks called in the transport profession "Twist lock" such as those equipping lifting beams for container handling, vehicles transporting containers, the containers themselves. (Figures 4 and 5).

In some cases, this will be the male part of the locks, or the female part of the locks or both, allowing the reversibility of the lashing compensator by turning it over according to its use as well as the handling of the machine and its load.

 - or toads "fixing ensuring adequately and safely the connection of the lashing compensator with the transport unit (Figure 6).

 -Either simply by means of holes allowing the connection of the lashing compensator with the transport unit by means of nuts and bolts.

- or by any other device with equivalent security
To constitute the lashing compensator, these three sub-assemblies will be assembled by bolting, thermal welding or any other process.

On these three sub-assemblies can be optionally added various complementary devices such as: -With regard to the timing function
damping or compliance device in wood, metal, material
composite, plastic or similar material
differential adjustment device for conforming the
tie-down compensator for the size of the batches of bare goods
or packed (Figure 7).

- Regarding the mooring function
.mooring devices complementary to those existing on the
transport equipment (e.g. central mooring point not existing
not on containers)
.Scaffolding allowing stacking of batches of naked goods
or packaged or improving stowage or avoiding bad weather with
addition of tarpaulin or bodywork.

-As regards the other functions related to the transport security of any other device (for example retention tanks, anti-vibration plates, cellular foam or other similar materials).

Implementation of the tie-down compensator.

This is done by simple juxtaposition of the different pre-defined elements of the component, then by assembling these various elements with bolts and nuts depending on the uses.

The securing of the lashing compensator on transport vehicles is done manually by means of twist locks or by means of wrenches to tighten the nuts of the toads or fasteners.

Characteristics -high mechanical resistance especially in the event of an accident.

 other high energy absorbing power in the three dimensions.

-Universal application "to regulated", including materials
radioactive.

-easy to ensure differential timing that can match precisely
the contours of naked or packaged goods and self-absorbing.

-the tie-down compensator being made up of standard elements
ISO or other systems of measurements and standards can be executed
industrially in series. the addition of complementary elements
can also be carried out in series because it involves equipping fleets
complete vehicles.

-before use, the assembly of the lashing compensator and its
attachment to the transport unit can be carried out manually or
using keys.
