Abstract

An arrangement for stabilising and positioning a container that has been pulled onto a vehicle by a load handling system includes a pair of elongate tension members 24. These each have at one end a means of connection to a support 20 on the the vehicle and at the other end a means of connection to the container 10 e.g. a twistlock. Each such elongate tension member 24 is constructed such that its overall length can be adjusted by a mechanism e.g. a ratchet handle - operated device 28, forming part of or attached to the tension member.

Description

FRONT STABILISER AND LOAD POSITIONING ARRANGEMENT FOR A LOAD HANDLING SYSTEM This invention relates to a load handling system (LHS) and to an arrangement for stabilising and positioning a load.

In an early design (U.K. Patent No. 1385997 published 1975) it was shown that a load could be pulled onto a vehicle using a so-called "cablelift".

However, this solution is not normally effective on vehicles destined for offhighway or cross-country use. Load handling systems (LHS) for loading a container or an elongate flat pallet (a flatrack) onto and off a vehicle over the rear of the vehicle have been developed. The mechanism which pulls the container onto the vehicle is often called a "hooklift". An example of an LHS is seen in European Patent 107892. Another example is described in U.S.

Patent 5,163,800.

Freight containers are produced in a series of standard sizes, as is well known, and such containers are known as I.S.O. containers. Flatracks according to I.S.O. dimensions are also known. Such containers and flatracks conventionally have corner fittings often referred to as corner castings.

Releasable securing means known as twistlocks are employed either for securing containers together, for example when they are stacked on a ship, or for securing them to transport vehicles of various kinds.

It would be desirable if there was available an arrangement for stabilising and/or positioning a load such as an I.S.O. container once it has been pulled onto a vehicle by an LHS.

According to one aspect of the present invention, there is provided an arrangement for stabilising and positioning a load that has been pulled onto a vehicle by an LHS, the arrangement comprising a pair of elongate tension members, each having at one end a means of connection to the vehicle and at the other end a means of connection to a container or other load to be carried by a vehicle, each such elongate tension member being constructed such that its overall length can be adjusted by a mechanism forming part of or attached to the member.

According to another aspect of the present invention there is provided an LHS on a vehicle, in which an elongate tension member is attached at one end to each side of the vehicle at a region to the rear of the vehicle cab in a manner permitting at least two-dimensional and preferably three-dimensional pivotal movement, and the other end of each elongate tension member has a means cf connection, e.g. a conventional twistlock, whereby it can be attached to a container or other suitable load carried by the vehicle, in order to adjust the position of the load longitudinally of the vehicle.

The elongate tension member serves to secure the load as well as properly positioning it.

According to a preferred embodiment of the invention, each end of each elongate tension member is provided with a spherical bearing.

According to another preferred embodiment of the invention, there is embodied in each elongate tension member, a means whereby its overall length can be adjusted.

The provision of spherical bearings and the length adjustment means has the advantage that the elongate tension member can be positioned at any one of a wide variety of angles to the vehicle longitudinal axis, in order to cope with a mis-positioned load, which can then be hauled into its proper loaded position by contracting each of the elongate tension members by an appropriate amount.

The invention will be better understood from the following non-limiting description of an example thereof given with reference to the accompanying drawings in which: Figure 1 is an end view, looking rearwardly from the vehicle cab, showing an I.S.O. container which has the hook arm of an LHS attached to it via a pair of tension links (such as are disclosed in our U.K. Patent Application No. 9504124.0).Figure 1 also shows a pair of elongate tension members connecting a twistlock to the container and extending between the container and the vehicle chassis; Figure 2 is a view similar to Figure 1 but on a larger scale, and showing the pair of elongate tension members about to be connected to the container; Figure 3 is a view similar to Figure 2 but showing the twistlocks engaged in the forward corner castings of the container; Figure 4 is an underplan view of the arrangement shown in Figure 3; and Figures 5 and 6 are side elevations showing an LHS hook and the forward part of a container loaded on the vehicle, Figure 5 showing the container slightly short of, and Figure 6 showing it at, its final loaded position.

Referring firstly to Figures 1 and 2, an I.S.O. container 10 having corner castings 12 is seen in its loaded position on a vehicle. The vehicle chassis is shown at 22. The hook arm 16 of the load handling system has laterally extending wings 18, which rest on a support base 20, in the vehicle fully loaded" position of the LHS. The support base 20 is mounted on the vehicle chassis 22.

Two tension links 14 connect the hook end of the LHS respectively to the two lower forward corner castings 12 on the container. The manner of connection will be described in more detail with reference to Figure 5.

A pair of elongate tension members 24, whose lengths are adjustable, each have one of their ends connected to a suitable mounting joint on the support base 20 which supports the LHS when in its fully loaded position. A spherical bearing joint 26 is located at each end of each elongate tension member 24. Each elongate tension member 24 is made in two parts, which are telescopically movable relative one to another, this movement being effected by any suitable mechansim such as a manually-operable ratchet handle device 30, seen in Figure 5. The handle 30 is carried by a support fixing 28 on the elongate tension member 24, but other means of providing an actuating force (e.g. hydraulic or pneumatic cylinders) to shorten or lengthen the elongate tension members 24 could of course be provided as an alternative.

The spherical bearings 26 at the respective free ends of the elongate tension members 24 connect each of the members 24 respectively to a conventional I.S.O. twistlock or other device which can make a secure engagement with the forward lower corner castings 12. As seen in Figure 2, the twistlocks are shown about to be inserted in the corner castings 12 of the container, whereas in Figures 1, 3 and 5, they are shown engaged in said corner castings. Laterally extending plates 40, as seen in Figure 4, extend horizontally outwardly from and are fixed, e.g. bolted to vehicle chassis members 22. At their outboard ends these plates 40 carry upstanding indicators 42, Figures 4 and 5 which are useful in determining whether the load handling system has reached its "fully loaded" position.

For a fuller explanation of the construction and operation of the tension links 14 and the corner connectors 44, the reader is invited to study our UK Patent Application No. 95-04124.0. The content of this application, a copy of which is filed herewith, is hereby incorporated in the present application.

In operation, in loading a container onto a vehicle using an LHS, firstly the corner connectors 44 (Fig.5) located at the free ends of the tension links 14 are engaged into the front lower corner castings 12 of the container. As will be appreciated, the upper ends of the tension links 14 are connected to the hook arm 16 by the pivotable link 36. The LHS is then actuated, and the L-shaped hook arm thereof describes an arcuate path in the conventional manner (see for example European Patent 107892) until the container 10, LHS and the tension links 14 arrive at the positions shown in Figure 5. The twist locks 32 at each free end of the elongate tension members 24 are then entered into and engaged in the front lower corner castings 12 of the container. If necessary to provide space for this engagement the corner connectors 44 are first removed from said corner castings.The handle 30 is then manually operated in a direction to contract the elongate tension members 24 so causing the container to be moved forwardly on the vehicle and to take up the position shown in Figure 6.

It will be seen that the invention as particularly described herein provides a simple and effective way of ensuring that the container is properly loaded onto, and adequately stabilised on the vehicle. This is of particular importance in LHS vehicles having military applications, because such vehicles may be required to travel over very rough terrain, while carrying heavy container loads or ammunition loaded onto flatracks. Examples of flatracks can be seen in our U.K. Patent Application No. 94-13609.0.

It will be appreciated that modifications may be made in the abovedescribed arrangement and in its component parts without departing from the invention. For example, while the form of tension link 14 shown in the drawings is advantageous, other forms of tension link could be employed.

Methods other than a manually operable handle could be employed to extend or contract the elongate tension members 24. While spherical bearings have been disclosed for employment at either end of the elongate tension members, other types of connection joint permitting movement of the elongate tension member in three dimensions could alternatively be employed.
