Description

The present invention relates to transportation

of cargoes.

  Some known road transport vehicles

  are designed to carry a load, for example a container

  ple, by means of pivoting latches arranged

  to situate in position and to fix each

  content. To use the swivel latch, it is passed

  in a non-circular hole, provided at the base of a

  at the bottom of the container, and then rotate it about 900 about a vertical axis, so that the head of the pivoting latch is not aligned with

  the main axis of said non-circular hole of the container.

  There are several container sizes, for

  example elements of 12 meters, 9 meters and 6 meters.

  Therefore, a transport vehicle, for example a semitrailer truck of 1.2 meters, is generally equipped with several groups of such pivoting latches, placed to correspond to the positions of the angles of all possible types of containers to be transported. In this case, there can often be twelve pivoting latches distributed on the transport vehicle in order to maintain,

  in use, the containers in an approved position

  suitable for correct weight distribution Swivel locks and containers are both compliant with

  well known international standard. As well as for

  other capacity or cargo carrier may

  can be transported in a similar way. These machines can

  such as bulk liquid tanks, flat container chassis, cargo containers

non-standard or platforms.

  The use of such means or carrier gear

  handling in load handling simplifies and accelerates

  many of the loading and unloading operations

  is lying. However, these cargo carrier devices must

  usually be returned empty to the location of

  before being reused. As a result, when

  carries an empty cargo carrier, or such

  filled with a low density load, the transport vehicle can be loaded to capacity by the cargo carrier and / or

  still within its allowable weight limits.

  Conversely, a high density load, for example steel bars, occupies a relatively small portion of the possible load volume of the carrier vehicle, which

  would be advantageously filled by an optimal load.

  The present invention relates to a method of fixing a removable cargo carrier device on a transport vehicle. The method according to the invention is characterized in that it consists in placing the cargo carrier device on supports, directed upwards to

  from the normal load receiving surface of the

  transport, so that an additional cargo

  can be carried in the space between the over-

  normal load-receiving side of the transmission vehicle

  port and the cargo carrier.

  Preferably, the transport vehicle is a

  truck, trailer or semi-trailer.

  Preferably, the cargo carrier device

  includes one or more standardized containers,

  Unstandardized cargo carriers, vats, flat container chassis or other platforms or receptacles

of cargo.

  Preferably, a support is provided each year.

  of a substantially rectangular cargo carrier

  lar. Preferably, the supports are equipped at their upper ends with pivoting latches, substantially

  of known type, located so as to mate with

  corresponding provisions in the carrier device

cargoes.

  Preferably, the supports are of high height

  above the normal receiving surface of

load of the transport vehicle.

  Preferably, the supports are fixed so

  removable to the normal load receiving surface of the

transport vehicle.

  Preferably, substantially horizontal rails can be attached to said supports so that, in use, these rails limit the movement of

  the cargo lodged below the cargo carrier

  sound, in a longitudinal-and / or transverse direction

  compared to the transport vehicle.

  The present invention also relates to a system for transporting a cargo carrier device,

  this system being characterized in that it comprises a vehicle

  transport, having a normal receiving surface

  charge, and a plurality of carriers which, when

  are directed upwards from the normal load receiving surface so as to maintain the

  cargo carrier above the level of the over-

  load receiving side, so that a cargo

  additional sound can be received between 1-normal surface

  load receiving device and the cargo carrier device

his.

  Preferably, these supports are vertically fixed

  on the transport vehicle by means of pivot bolts

  substantially of known type attached to the surface

  normal load reception of the transport vehicle.

  Preferably, the supports may be retractable

  folded, removed or stored in a rest position, as appropriate, when not in use, so that the surface of the load

  transport vehicle is substantially flat and horizon-

tale.

  Preferably, the supports are stored at

  pos so that the cargo carrier device can be attached to the normal load receiving surface of the transport vehicle by means of conventional pivoting latches attached to this surface. The present invention also provides a support for the implementation of a cargo carrier device on

  a transport vehicle, this support being provided for

  be attached, removably, to the

  cargo so that, in use, the support

  keep the cargo carrier above the overhead

  normal load-receiving side of the transmission vehicle

  Harbor. Preferably, this support is equipped with substantially usual pivoting latches, at its upper end,

  to hold in position and fix the carrier device

  cargoes. Preferably, the support is adapted to be retracted, folded or stored, when not in use, so as to leave the normal surface substantially flat.

  receiving the load of the transport vehicle.

  Preferably, the support can be fixed in

  vertical position on the transport vehicle, by conventional pivoting latches attached to the normal surface of the

  receiving the load of the transport vehicle.

  Preferably, the support can be equipped with substantially horizontal rails which, during use, limit the transverse and / or longitudinal movement of the cargo housed between the normal surface of reception.

  of the transport vehicle and the device carrying

cargo.

  The support can be an integral element of the

  transport or can stand freely on the

  normal load-receiving side of the transmission vehicle

  port, either individually or connected by spare parts

  look appropriate to one or more similar supports.

  Advantageously, the support is removably attached to the transport vehicle and is arranged so that it can be stored, when it is not necessary, so as not to hinder the usual use of the vehicle. The present invention enables a carrier to place a more effective combination of general cargo, including both high density cargoes and

  low density, on the same transport vehicle. This category

  feature is particularly useful for transportation

  empty containers or cargo carrier devices

  blends, in combination with loads such as, for example, steel bars, ingots, drums,

  cement products and other general cargoes. The accrois-

  operation makes the transport of an optimal load for each transport unit more and more desirable, so that such combinations of

  charges are economically advantageous.

  The invention will be better understood in the light of

  the description of its embodiments, not limited to

  load of the trailer 1. The container 7 is sup-

  carried over the normal load-receiving surface by four supports 3, of which only the left-hand carriers 3a and 3b are shown. The central supports

  are in the storage or rest position.

  When you do not wish to transport

  tif cargo carrier, containers for example, above

  the normal load receiving surface of the trailer

  that the supports 3 can be folded into

  provided in the surface 5, so as to be placed, as shown in Figure 1, with their positioning and locking portions located horizontally,

  in order to leave the load receiving surface 5 sensi-

  in the same state as in a trans-

usual port.

  Figures 2 to 4 represent a form of

  the use of a support and a trailer, according to the

  the invention. In this arrangement, the supports pivot from a horizontal storage or rest position to a vertical working position and they are maintained in the

  vertical position by the initial mechanism of

  voting provided with the trailer. In the storage position, the supports are in the plane of the surface 5 of

  load reception of the trailer.

  FIG. 3 shows that the surface 5 of

  the load of the trailer, substantially of the usual type,

  has notches oriented transversely towards the

  from the edges of the surface 5. At the end

  front or rear of the notch relative to the trans-

  port, a mechanism 43 with pivoting latch, substantially

  standard type, passes through a support plate 41.

  members 40, substantially L-shaped, are arranged

  on both sides of the mechanism 43 with pivoting latch. At the ex-

  lower end of the vertical portion of each piece 40, the farthest from the mechanism 43 with pivoting latch, is provided a circular hole 42 which can advantageously

be equipped with a socket.

  The supports are constituted by pieces

  L-shaped members 33, whose spacing of the parallel parts is slightly smaller than the spacing of the parallel parts of the corresponding L-shaped parts 40 on the trailer. Parts 33 also have, at their lower end, holes 36 which can also be equipped with bushings 38. The holes 36 formed in

  the parts 33 are connected by a cylinder 35, fixed perpendicularly

  specifically to the plans of the L-shaped pieces 33 and

tending between these pieces.

  An amount 37, with a rectangular cross-section

  laire, is fixed between the horizontal arms of the L-shaped pieces 33 and is directed vertically upwardly from these arms. The amount 37 includes a sole

  39, pierced by a rectangular hole through which the metal

  canism 43 with pivoting latch can protrude and

rust, when using.

  The upper part of the upright 37 comprises a plate 45, perpendicular to the longitudinal axis of the upright 37. A pivoting latch 49 is fixed in the central part of the plate 45. The latch 49 has a substantially rectangular horizontal cross section, corresponding to similar-shaped dwellings provided for in

Cargo carrier to be transported.

  An operating rod 53, at the lower end

  a handle 51, through which a circular hole is provided in the plate 45 and the latch 49. The handle 51 can be accessed through an opening 47 extending on the outside of the U-shaped post 37. To In use, the support is held in place on the trailer by introducing a retaining pin 57 into the holes 36 and 42. In the rest position, the support can pivot about the axis 57 so as to bring the surface of the upright 37 substantially in the same plane as the upper surface of the normal load bearing platform 5 of the trailer. A loaded container can then be fixed in the usual way to the mechanism 43 with pivoting latch,

if you wish.

  In the working position, the support is pivoted upwards about the retaining pin 57, and then fixed in position by means of the pivoting latch mechanism 43 which is inserted into a hole in the sole 39 of the upright 37 The lock is then rotated about 900 in the usual manner to secure the support in the vertical position. A container can then be blocked in the usual way, by the mechanism 49 with pivoting latch located

at the top of the amount 37.

  To secure a cargo carrier, a

  content for example, the support, it blocks the latter in the vertical position and lowers a container on the support. The top of the pivoting latch 49 is aligned with

  an oval hole provided in the base of the container and is

  thus troduces into this hole. Axially rotates

  turn lock of about 900, so as to bring the

  upper tie-lock out of alignment with the oval hole of the container. With the help of the handle 51 of the lock, the upper part of the lock is then screwed down to bring it into contact with the base of the container, which

  securely locks it in position on the support.

  In an alternative embodiment, the supports

  can be permanently attached to the trans-

port, for example by welding.

  In another embodiment of the invention, shown in FIG. 5, two supports 63 may be connected together at their lower ends by a beam 61, made of steel, for example, so that

  during use the stands 63 stand upright

  the load receiving surface 5 of the

  transport gin, the beam 61 resting transversely on the surface 5ô In this arrangement, the supports 63 are held in position by the locking with the locks

  conventional swivels, fixed to the receiving surface of

  age of the transport vehicle and the weight of the cargo

  transported additional sound which rests on the transverse beam 61, which holds it in position. This embodiment is particularly suitable for use with loads such as steel bars and may be preferred over the other embodiments described in that no modification of the transport apparatus is necessary. An extension starting from the lower part of each of the supports 3, perpendicular to the beam

  61, forwards or backwards, avoids

  support during braking or acceleration.

  transport vehicle. When they are not born

  the free-standing supports, such as the supports 63, can advantageously be housed under the

  load receiving surface 5 of the transport vehicle.

  In an alternative embodiment, the supports may be designed to be able to slide vertically through holes provided in the load receiving surface of the transport unit, from a rest position to a working position. Such support can be maintained

  in the desired position, for example by means of pins.

  All the components of the device according to

  invention can be made in any

  priate. For example, a support according to the invention

  may consist of a steel section, with a cross-section

  tangular, tubular, U-shaped or angle.

  It is understood that modifications of detail may be made in the form and implementation

  of the method and the device according to the invention, without

shot from the frame of it.
