`PLATFORMS FOR USE IN TRANSPORTERS
`
`Field to the Invention
`
`s

`

`
`3 o
`
`The present invention relates to platforms for use in
`transporters, a trailer comprising a movable platform and
`especially, but not
`limited to, platforms for use
`in
`livestock
`transporters
`and
`a
`trailer
`for use
`in
`transporting livestock comprising a movable platform.
`
`Background to the Invention
`
`Trailers for use in transporting livestock generally
`comprise a number of levels each level having a platform
`to support the livestock. Such trailers enable livestock
`to be transported economically and efficiently. Trailers
`for supporting livestock may comprise an integrated cab
`plus
`transport area or comprise a
`trailer forming a
`livestock area to be towed behind a lorry.
`
`The trailer may have at least one platform which is
`vertically moveable within the trailer in order for the
`height of the level to be adjusted according to the type
`of goods being transported.
`In livestock transporters,
`the height of the level will be dependent upon the type of
`livestock being
`transported.
`For
`example,
`a
`level
`supporting cattle will require a greater height than a
`level supporting poultry or sheep or pigs. Accordingly,
`it is advantageous for a trailer to have a platform which
`can move vertically within the trailer in ·Order for the
`trailer
`to
`transport different goods efficiently and
`economically.

`
`However, when a platform supporting goods is moved/
`the platform may not
`remain
`in a horizontal plane,
`especially, if the goods are not distributed evenly across
`the platform. This results from the drive means moving
`the platform higher vertically in regions supporting less
`weight.
`Prior art methods which try to address this
`problem have used a cog mechanism and hydraulic geared
`floor dividers in order for the platform to remain in a
`horizontal
`plane.
`However,
`such mechanisms
`are
`10 mechanically complicated and are difficult to clean. This
`is especially apparent in trailers for use in transporting
`livestock which need to be cleaned to a high standard
`frequently.
`Accordingly/
`such
`platforms
`can
`be
`restricting in transporting livestock.
`
`15
`
`It is an aim of the present invention to overcome at
`least on problem associated with the prior art whether
`referred to herein or otherwise.

`levels of
`livestock.
`Each level has a platform 18, 20, 22 for
`supporting the livestock thereon.

`
`level 12, 14, 16 is dependent upon the type of livestock
`being supported. Accordingly, it is advantageous for each
`platform 18, 20, 22 to be supported in the trailer 10 such
`that
`the vertical position of each platform can be
`adjusted in the trailer in order for the trailer to be
`adapted to transport different types of livestock.
`The
`platform 18 of the first level may be fixed since it is
`the floor of the trailer 10 and,
`therefore, cannot be
`moved vertically downwards.

`
`important for each
`it is
`in Figure 2,
`shown
`As
`platform to be substantially horizontally supported in the
`trailer. With platforms 24 that are vertically adjusted
`using a hydraulic piston or ram 26 it is easy to locate a
`linear transducer (not shown) within the cylinder 28 in
`order to monitor and record the vertical extension of the
`extension member 28.
`However, platforms 24 for use in
`trailers generally need to be moved vertically over a
`relatively large distance.
`Accordingly,
`the extension
`20 member 30 needs
`to be extended over
`a
`substantial
`distance.
`This
`requires a
`relatively
`long extension
`a
`member 30
`and
`corresponding cylinder 28.
`This,
`therefore, greatly restricts the amount that the platform
`can be
`lowered since
`the platform 24 must always be
`located above the cylinder 28 of the hydraulic piston, as
`shown in Figure 2.

`shown in Figure 3.
`One end of the sleeve member 31 is
`connected to the top of the extension member 3 0 and the

`through the
`sleeve member 31
`such
`that
`the platform
`is
`located
`vertically below
`the end of
`the extension member 30.
`if a
`large single stage cylinder was used then
`5 However 1
`the sleeve 31 would project upwardly from the platform 24
`and possibly interfere with the other platforms or the
`for example, if the upper deck was
`roof of the trailer 1
`required to be positioned relatively close to the roof of
`the trailer (for example, for small livestock)
`then the
`sleeve 31 and extension member 30 would need to protrude
`through the roof of the trailer, which is not acceptable
`in trailers.
`
`10
`
`15
`
`20
`
`A number of hydraulic pistons are required in order to
`raise and lower the platform 24 vertically relative to the
`trailer 26.
`These pistons are preferably located around
`the periphery of
`the platform 24.
`Alternatively,
`pneumatic or other suitably powered pistons may be used.
`If the platform 24 has goods supported thereon and the
`platform 24 is raised or lowered then the distance that
`the extension members 30 of the pistons are extended may
`be different. This may result in part from the weight of
`the goods supported on
`the platform not being evenly
`25 distributed
`over
`the
`area
`of
`the
`platform
`24.
`Accordingly,
`in areas where a relatively low weight of
`goods are supported the platform may be moved upwardly
`more easily. Accordingly, it is necessary to measure the
`amount of extension of the extension members 30 in order
`to determine whether
`the platform 24
`is substantially
`horizontal.
`In prior art methods, linear transducers have
`been used which secure within the cylinder of the pistons.
`Such transducers are adequate for single stage pistons.

`
`if multistage pistons are used to enable the
`However 1
`platform to be raised and lowered over a greater distance
`then a simple linear transducer cannot be used.
`
`s
`
`10
`
`15
`
`In a preferred embodiment of the present invention a
`cable extension transducer 38 is used, as shown in Figure
`4.
`A multistage piston has an extension member which
`comprises a plurality of stages 34, 36 and a single
`cylinder 32. The advantage of multistage pistons is that
`the height of
`the housing only needs
`to be slightly
`greater
`than
`the
`length of
`the
`longest stage of
`the

`useful in situations where space is important. However,
`linear transducers cannot be used to measure the overall
`length of extension of the extension member.
`
`20
`
`The cable extension transducer 38 is located adjacent
`to the cylinder 32 of the multistage piston.
`The cable
`extension transducer 38 has a
`flexible cable 40 which
`extends from a housing.
`The flexible cable 40 has a
`fixing plate 42 at the end thereof. The fixing plate 42
`is secured to the end of
`the first stage 36 of
`the
`extension member.
`Accordingly,
`the cable extension
`transducer can measure the overall length of the extension
`25 member comprising a plurality of stages.
`
`30
`
`The cable extension transducer 38 comprises a housing
`from which the flexible cable 40 can be pulled out from,
`as shown in Figure 5. The flexible cable 40 is contained
`on a spool 44 in the housing.
`The flexible cable 40 may
`be
`a metal cable.
`The
`spool has spring means 46
`associated therewith. The spring means urges the flexible
`cable to be wrapped around the spool 44. Accordingly, if

`the
`then
`the extension member shortens
`length of
`the
`flexible cable is wound around the spool so that a new
`measurement may be taken.
`The cable extension transducer
`comprises a printed circuit board 48 for measuring and
`recording
`the
`length of
`the extension member
`and,
`accordingly, the position of the platform.
`
`The trailer has a number of multistage pistons located
`A single control
`around the periphery of the platform.
`and measurement means may be used in order to co-ordinate
`the lifting and
`lowering of
`the platform in order to
`ensure that the platform is substantially horizontal after
`moving the platform.
`
`As shown in Figure 6, the multistage piston is located
`within a sleeve member 39. The end of the upper stage 36
`provides a ram socket 50 in order to co-operate with the
`upper end of the sleeve member 3 9 in order to move the
`platform 24. The trailer has a
`locking track 52 provided
`on its inner surface.
`The locking track 52 is provided
`with a plurality of supporting portions 54 which are
`arranged to engage with a locking element provided on the
`platform 24.
`The locking element is arranged to engage
`with the supporting portion 54 in order to support and
`lock the platform 24 in position relative to the trailer.
`The locking track 52 may be adjustable in order for the
`space between adjacent supporting portions 54
`to be
`altered depending upon the individuals requirements.
`
`As shown in Figure 7, the locking element comprises a
`locking piston 56 which is connected to a
`locking plate
`58.
`The
`locking piston 56 may be pneumatically,
`hydraulically or mechanically powered. As the platform 24

`
`10
`
`is moved upwards, the locking piston 56 and locking plate
`58 automatically follow the profile of the locking track
`52.
`
`When the locking piston 56 is fully extended and the
`locking plate 58 is engaged in the supporting portion 54
`of the locking track 52 a signal, preferably electrical,
`is
`transmitted
`from a
`sensor
`to a controller.
`The
`platform 24 has a plurality of locking elements located
`around its periphery and each locking element transmits a
`signal when the relevant locking piston is fully extended
`and engaged within a supporting portion.
`The controller
`monitors the signal and provides display means to display
`when all the locking pistons are fully extended and the
`respective
`locking plates are engaged in a supporting
`portion of the relevant locking track.
`
`This provides a safety feature whereby the user is
`informed when the platform is safely engaged or is not
`fully engaged. The platform may be lowered by retracting
`the locking pistons using suitable means.
`
`5
`
`10
`
`15
`
`20
`
`The locking pistons and locking plates may be arranged
`to automatically disengage when the multistage piston is
`powered.
`
`25
`
`One main advantage of the present invention is that it
`allows the exact position of each individual multi-stage
`cylinder extension heig~t to be measured and controlled.
`30 Once
`this position is known accurately it allows all
`cylinders to be independently controlled using computer
`control in order to maintain a perfectly level position.
`Alternatively,
`the
`cylinders
`can
`be

`to ease the unloading of heavy loads or alternatively for
