The means 90, 86 also serve to receive a tine of a mobilizer gear. The floor 36 of the outer shell may be hinged at 37 to that of the main shell. Carbon fibres 82 are laid on the floor of the first chassis 14 to assist sliding of the second chassis. The outer shell may be locked in the retracted position by a pin 115 axially slidable in a bore in the outer shell 23 and receivable in a socket 110 in the main shell 17, the socket mounting a peg 123 of semi-circular section in a transverse bore 122, the arrangement being such that, in the position shown, the peg 123 does not obstruct the entry of the pin 115 into the socket, but the peg may be axially rotated to lockingly engage a circumferential groove 117 on the pin 115. A ring 120 enables the cabin to be lifted. A drainage duct is provided in the sockets base. (For Figures see next page)
