The present invention relates a trailer jack (10) having two configurations for lifting and supporting wheeled modes of transport and, in particular, for raising either a single axle trailer or a multi (dual) axle trailer. In a first configuration, the trailer jack (10) is arranged to engage with the sole axle of a single axle trailer. The trailer jack (10) raises the axle directly and hence the wheels mounted thereon such that a wheel can be removed and replaced. This is achieved without having to engage the trailer jack (10) at a reinforced position on the body shell of the trailer or under a dedicated position on a chassis of the trailer. Furthermore, as will be explained, the movement of the trailer jack (10) to the raised position is achieved through the movement of the trailer without the need for any manual or hydraulic lifting mechanism. |
