A trailer (10) for picking up and transporting a load (200) includes a pair of chassis sides (12, 14) each chassis side including wheels (110) supporting the trailer, and a protrusion (150) for engaging with a load to be picked up and transported. The trailer also includes a cruciform link mechanism (36, 38) for expanding and contracting the trailer by moving the chassis sides (12, 14) towards and away from each other. This enables the device to be positioned on either side of a load (200) in an expanded state and subsequently contracted to engage with the load. The cruciform link mechanism (36, 38) is located above the load in use and comprises two link members (36, 38) of substantially equal length which are pivoted to each other at their respective centres (58) where they cross and which link the chassis sides together. |
