Description

IMPROVEMENTS IN MW RELATING TO SAFETY BARRIERS
Field of the Invention
The invention relates to safety barriers and to methods of using barriers.
Background to the Invent ion
It is know for workers (erectors) to climb onto lorries and trailers in order to attach crane hooks to steelwork members and other materials so that they can be off-loaded at a construction site. This practice involves the workers operating at height and thus being exposed to the risk of a fall and potential injury.
A number of methods have been used to reduce the risk to workers. For example, one method involves fitting barriers to a lorry or trailer bed. However, this can restrict the working space on the lorry or trailer bed. Additionally, trailers and lorries generally require modification to provide attachment points for such barriers. The use of such barriers may therefore be inconvenient In another known method, secure fixing points are provided on a lorry or trailer for workers wearing inertia harenesses to clip into. Thus, should a worker fall that fall is arrested. However, this is a fall protection rather than a fall prevention method and thus may not protect workers as well as might be desirable.
Accordingly, the present invention aims to address at least one disadvantage associated with the prior art whether discussed herein or otherwise.
Summary of Invention

Brief Description of the Drawings
The present invention will now be illustrated by way of example with reference to the accompanying drawings in which: Figure 1 is an end view of a trailer and barrier; Figure 2 is a side view of the barrier of Figure 1 (trailer omitted); Figure 3 is a detailed view of a stabilising means of a barrier (showing hidden detail); Figure 4 is a detailed view of a base part of a barrier; and Figure 5 is an end view of a trailer and base unit of a barrier.
Figure 6 is a side view of a trailer and an alternative embodiment of a barrier.
Detailed Description of Preferred Embodiments
As best illustrated by Figures 1 and 2 a barrier 10 comprises a base 20 for engaging the ground 100 and uprights 30 connected to and extending upwardly from the base 20. Together these form a base unit 40. A guard means which comprises a guard frame 50 is connected to the base unit 40. This frame 50 comprises a plurality of guard rails 60 which are mounted to standards 70.
The barrier 10 also comprises stabilising means comprising connectors 80 for connecting the barrier 10 to a trailer 1, or alternatively a lorry (not shown), to provide the barrier 10 with lateral Btability. As shown by Figure 2, barriers 10 can be connected to either side of a trailer bed 3 to provide a barrier and vehicle assembly.
As shown by Figure 3 the stabilising means comprises connectors 80 (one shown) each of which couples to a mounting point of a trailer (or lorry) bed 3. In the illustrated embodiment of Figure 3 the connector 80 comprises a chain type clip. Figures 1 and 5 illustrate a slightly different arrangement of the connectors 80 but are generally the same. In an alternative embodiment (not shown) a connector comprises a plate attached to the upright and bolted through the trailer timber deck.
Figure 3 also illustrates the connection of a standard 70 of the guard means to the upright 30. The upright 30 comprises a pot 33 (tubular post) into which the standard 70 which comprises a post 71 locates. The upright further comprises a fixing means comprising a partly threaded aperture 35 provided by nuts 37 (one shown) welded to the pot 33. A bolt (not shown) can be passed into the aperture 35 and tightened to clamp the standard 70 in place.
Figure 4 shows the connection of an upright 30 to the base 20. The upright 30 comprises a plate 38 attached to an end of the pot 33 of the upright 30. This plate 38 comprises apertures 39. The base 10 comprises a steel beam 11 comprising apertures 13. Apertures 39 of the upright 30 are aligned with apertures 13 of the base 10 and connected by bolts (not shown).
In use a barrier is assembled by locating a base 10 into position using a crane (not shown) so that the base is arranged to lie adjacent a trailer 1 (or lorry).
The uprights 30 are then positioned onto the base 10 and tack bolted into place (bolts not shown). After this landing bolts (not shown) are then placed through the plates 38 of correctly positioned uprights 30 to securely connect them to the base 10.
This creates a base unit 40 as best illustrated by Figure 5. Connectors 80 are then used to connect this unit 40 to a trailer 1 (or lorry) to provide the base unit 40 and subsequently barrier 10 with lateral stability.
The guard rail frame 50 is constructed on the ground using guard rails 60, standards 70 and load bearing guard rail connectors 61 which join them.
The guard rail frame 50 is then lifted by a crane (not shown) and guided into place with the aid of cherry pickers (not shown).
Clamping bolts (not shown) are placed in position and tightened to clamp the standards 70 of the guard rail frame 50 in place relative to the uprights 30.
Lastly, the bolts connecting the uprights 30 to the base can be tightened once the guard rail frame 50 is in its final position.
The barrier can be disassembled by reversing this process.
Figure 6 illustrates an alternative embodiment of a barrier. The barrier 200 is substantially the same as that of barrier 10 of figure 1 and thus the component parts are not discussed in detail. The distinction is that the barrier 200 further comprises a link means comprising a link member 210 for connecting uprights 220 to one another near their upper, in use, ends.
It will be appreciated that preferred embodiments of the present invention may provide barriers which offer a convenient and effective means in which to protect workers operating on the beds of a lorries and trailers.
