Figure 23 shows a side elevation view of the vehicle 200 engaged with the item 18, the item 18 0 being in a vertical orientation and at a raised position. Figure 24 is a front elevation view corresponding to the view of figure 23. The carriage has been raised after the the forks have been pivoted upward. Figure 25 is a front elevation view of the vehicle 200 engaged with the item 18, the item 18 being in a horizontal orientation and at a raised position and rotated around a longitudinal axis of 5 the vehicle. Figure 26 is a front elevation view corresponding to figure 25. An embodiment of a method of installing a panel may be understood with reference to at least some of the figures I to 11 and 14 to 27. In one step of the method (figs. 1 and 2), the panel 18 is engaged with an item engager of the vehicle 10, 100, 200. In another step of the method (figs. 3 and 4), the item engager height adjustment mechanism is operated to raise the item engager 16. 0 In yet another step of the method (figs. 5 and 6), the vehicle 10,100,200 is rolled to a location at which the panel 18 is to be installed. In still another step (figs. 7 and 8), the item engager height adjustment mechanism is operated to lower the item engager 16. In still yet another step (not shown), the panel 18 is disengaged from the item engager. Disengagement may be achieved in one embodiment by, for example, lowering the forks and removing the bar 34 from the 25 passageway 20. In an alternative embodiment in which engagement is by inserting a prong of the item engager into a cavity of the item, disengagement may be achieved by withdrawing the prong of the item engager from the cavity. The steps may be performed by a single user or worker. In optional steps, the vehicle 10,100,200 may be manually rolled on the surface 14, for example 30 by a user acting on the handles 24, 26. While the vehicle 10,100,200 is rolled to the location, the plurality of casters (or other wheels) may conveniently swivel to improve manoeuvrability. The panel 18 may be lowered on a starter 48 in the form of a starter bar. The starter bar comprises an 10 elongated spine having a plurality of prongs for being received into a plurality of panel cavities. The starter 48 may be fixed adjacent the surface 14, for example. The starter may be used to locate the panel at the correct installation position. In some but not all embodiments, the step of engaging the panel 18 with the item engager 16 5 comprises the step of passing the bar 34 through the passage 20 formed in the panel 18. Once engaged, the bar 34 and the panel 18 may move by a gravity bias toward the vehicle body 12. This may improve stability and improve the security of the panel so engaged. During the operation of the item engager height adjustment mechanisms, the at least one outer tube 38 and the at least one inner tube 36 may be slid with respect to the other. This may be 0 effected by operation of the hydraulic system 42 so causing the push rod 43 to exert a force on the cross bar. Alternatively, the winch system 102 may be operated in embodiments that have a winch system 102 causing sliding motion between the inner tube 36 and the outer tube 38. In an optional step, once the panel 18 is at the location it is to be moved to, the outrigger 46 may be extended. This may improve stability while the panel 18 is lowered. Subsequently the 5 outrigger may be retracted. Now that embodiments have been described, it will be appreciated that some embodiments have some of the following advantages: * It may be easier and more convenient to move a panel into position using a vehicle disclosed herein. 0 0 A single person may be able to move the panel into position. * It may be more convenient to use a vehicle disclosed herein than an existing machine to move a panel into position. * Embodiments that are motorised may be easier to operate, especially for less capable workers, and/or able to move heavier items. 25 - Embodiments that are not motorised my be more reliable and/or operable at locations where access to power is difficult or impossible for example some construction sites. Variations and/or modifications may be made to the embodiments described without departing from the spirit or ambit of the invention. For example, the engager may be for engaging another item in the form of timber frames, or generally be for engaging any suitable item and may be 30 suitably configured. Motorised and manual actuation may be interchanged as desired and/or 11 suitable. The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive. Prior art, if any, described herein is not to be taken as an admission that the prior art forms part of the common general knowledge in any jurisdiction. 5 In the claims which follow and in the preceding description of the invention, except where the context requires otherwise due to express language or necessary implication, the word "comprise" or variations such as "comprises" or "comprising" is used in an inclusive sense, that is to specify the presence of the stated features but not to preclude the presence or addition of further features in various embodiments of the invention. 0
