[0001] The present disclosure relates to a semi-trailer. Ina particular form the present disclosure relates to a semi-trailer of the type commonly known as a low loader, lowboy or float, and a bogie for such a trailer, although its application need not be so limited.
[0002] Lowboy trailers generally comprise a forward most gooseneck, a rearmost set of wheels and a trailer body interposing these, the trailer body comprising a deck which is set low between the gooseneck and the wheels. This low deck height permits these trailers to carry high loads, which other trailers cannot. Consequently, lowboys are used to haul heavy equipment such as bulldozers, dump trucks, loaders, harvesters, tractors and other sizable industrial equipment.
[0003] In cases where a given lowboy trailer is insufficiently long for a given load, or lacking sufficient load bearing capacity to carry this load, then a different lowboy trailer must be sourced, and trailers of this type are high value assets.
[0004] It is against this background, and the problems and difficulties associated therewith, that the present disclosure has been developed.
[0005] Certain objects and advantages of the present disclosure will become apparent from the following description, taken in connection with the accompanying drawings, wherein, by way of illustration and example, an embodiment of the present invention is disclosed.

[0050] Figure 7 is a side view of the rear end of the lowboy trailer with the bogie attached thereto;
[0051] Figure 8 is a cross-section view through the bogie taken at A-A; and
[0052] Figure 9 is an isometric view of a rear of the lowboy trailer.
[0053] In the following description, like reference characters designate like or corresponding parts throughout the figures.
[0054] Referring now to Figure 1, there is shown a bogie 1 (i.e. an extension bogie 1) for extending a lowboy trailer 100, according to an embodiment.
[0055] The extension bogie Icomprising a body 2 supported on at least one axle assembly 10 via a suspension system or arrangement 20. The or each axle assembly 10 comprises a heavy duty axle beam 12 with a dual wheel set 14 at each end. While one axle assembly 10 is illustrated, a bogie with multiple axle assemblies 10 is conceivable.
[0056] With reference to Figure 8, it can be seen that the body 2 comprises a pair of parallel chassis rails 4 extending between a forward end 2A and a rear end 2B thereof. The body 2 further comprises a plurality of top plates which cooperatively define a top 6 of the bogie body 2, where this top 6 extends between the forward and rear ends 2A and 2Bof the body 2, and between a pair of side plates 8, each of which defines a wheel arch 9 extending over a dual wheel set 14.
[0057] Each of the chassis rails 4 of the bogie body 2 comprises a through aperture 5, through which the axle beam 12 of the axle assembly 10 extends, so that the top 6 of the body can match a rear end deck height of the lowboy trailer 100.
[0058] The suspension 20 comprises a pair of control arms 22, each of which extends rearward from a forward pivotal mounting point 24 on the body 2, to the axle assembly 10. A pair of pneumatic springs 26 extend between the axle beam 12 and the body 2, although it should be understood that mechanical springs could be employed in place of these. A pair of shock absorbers 28 (see Figure 4) extend between the control arms 22 and the body 2.
[0059] At a forward end 2A of the body 2 thereof, the extension bogie1 comprises attachment means 40 adapted to rigidly secure the bogie 1 with respect to a rear end of the lowboy trailer 100. In the case of this illustrated embodiment, the attachment means 40 comprises a clamping means for clamping a portion of the rear end of the trailer 100. This clamping means comprises an upper jaw 42 and a lower jaw 44, between which a rear end of the trailer 100 is to be secured.
[0060] With reference to Figure 1, it can be seen that the forward end 2A of the body 2 comprises a steel front plate 46 which extends the full width of the body 2, a lower edge of which is bent forward and then upward to form the lower jaw 44, which in turn defines an upwardly opening channel 48 with closed ends, which similarly extends the full width of the body 2.
[0061] The upper jaw 42 is similarly formed from apiece of steel plate, a forward edge of which is bent to form a downwardly directed lip 42A extending from a flange 42B. The upper jaw 42 is secured with respect to the body, in this case by bolting through the flange 42B into the body 2.
[0062] In use, the extension bogie 1 can be secured to a rear end of a trailer 100, by separation of the upper jaw 42 from the bogie 2, or at least loosening of the bolts 43 retaining the upper jaw 42 sufficient that a rear cross member (or bumper) assembly 110 (see Figure 6) of the trailer 100 can be received between the upper and lower jaws 42 and 44, with a lower edge of the rear cross member assembly 110 nested in the channel 48 of the lower jaw 44. The bolts for the upperjaw can then be tightened, thereby effecting secure attachment of the extension bogie 1 to the trailer 100, as illustrated in Figure 6.
[0063] When attached in this fashion, the top 6 of the bogie 1 provides an extension of the trailer 100, and in this way the trailer 100 can handle longer loads than it could otherwise accommodate. Moreover, the axle assembly 10 of the bogie 1 provides additional load bearing wheels, so that the trailer 100 can handle heavier loads than it could otherwise accommodate.
[0064] The rearward end 2A of the body 2 comprises its own rear cross member (or bumper) assembly 110, to which a further extension bogie 1 could conceivably be secured. This rear cross member assembly 110 could also conceivably comprise brake lights 112 and indicators 114. To this end, the bogie 1 would further comprise electrical connectors for the lights, and air line connectors for the pneumatic springs 26.
[0065] In a non illustrated embodiment, the body 2 is adapted for attachment of a fifth wheel thereto. In this way, a further trailer could be attached to the extension bogie 1 to form a road train.
[0066] Referring now to Figure 9, where a rear of the trailer 100 is illustrated. The trailer comprises electrical connectors 120 for electrically connecting the bogie 1 to the trailer 100, and pneumatic connectors 130 for pneumatically connecting the bogie I to the trailer 100.
[0067] Throughout the specification and the claims that follow, unless the context requires otherwise, the words "comprise" and "include" and variations such as "comprising" and "including" will be understood to imply the inclusion of a stated integer or group of integers, but not the exclusion of any other integer or group of integers.
[0068] The reference to any prior art in this specification is not, and should not be taken as, an acknowledgement of any form of suggestion that such prior art forms part of the common general knowledge.
[0069] It will be appreciated by those skilled in the art that the invention is not restricted in its use to the particular application described. Neither is the present invention restricted in its preferred embodiment with regard to the particular elements and/or features described or depicted herein. It will be appreciated that the invention is not limited to the embodiment or embodiments disclosed, but is capable of numerous rearrangements, modifications and substitutions without departing from the scope of the invention as set forth and defined by the following claims.
