A wheeled bogie unit is engageable with one end of a chassis of a treatment plant to support that end of the chassis above the ground for the suspended transport of the plant. The bogie unit has a chassis, at least one wheel set supporting the chassis, a lifting cradle mounted on the chassis and having a projecting end which is engageable with the end of the plant chassis, a support and guide surface provided on the projecting end of the cradle which is engageable with a lifting surface provided on the end of the plant chassis, in order to suspend one end of the plant chassis above the ground, and a slide mounting the cradle on the bogie chassis for relative slidable movement between a lowered position and a raised lifting position. In the lowered position, the end of the plant chassis is standing on the ground adjacent thereto. In the raised lifting position, the end of the plant chassis is lifted off the ground and is supported by the support and guide surface of the lifting cradle.

The invention claimed is: 1. A wheeled bogie unit which is engageable with one end of a chassis of a treatment plant, in order to support that end of the plant chassis above the ground for the suspended transport of the plant, in which the bogie unit comprises: a bogie chassis; a front axle mounting a front wheel set and a rear axle mounting a rear wheel set to support the bogie chassis; a lifting cradle mounted on the bogie chassis and having a projecting end which is engageable with said one end of the plant chassis; an inclined support and guide surface provided on the projecting end of the cradle and engageable with an inclined lifting surface provided on said one end of the plant chassis, in order to suspend said one end of the plant chassis above the ground; a slide arrangement mounting the cradle on the bogie chassis for relative slidable movement along an inclined plane of movement between a lowered position of engagement with said one end of the plant chassis, when the latter is standing on the ground adjacent thereto, and a raised lifting position in which the end of the plant chassis is lifted off the ground and is supported by the inclined support and guide surface of the lifting cradle; and a mounting bracket via which the lifting cradle is mounted on the bogie chassis at a position between said front and rear axles, the mounting bracket configured to allow the cradle to pivot relative to the bogie chassis; wherein said front and rear wheel sets, via said front and rear axles are configured to support the bogie chassis and bear the weight of the treatment plant at the lower position of engagement and the raised lifting position. 2. The wheeled bogie unit according to claim 1, in which the lifting cradle is slidably mounted on the bogie chassis, for movement between the lowered position of engagement and the raised lifting position. 3. The wheeled bogie unit according to claim 2, wherein said mounting bracket is configured to pivot on the bogie chassis to distribute the weight of the suspended treatment plant between the front and rear axles. 4. The wheeled bogie unit according to claim 3, including spacers and clamping strips which mount an underside of the lifting cradle on the mounting bracket, allowing free lengthwise movement of the cradle relative to the bogie chassis. 5. The wheeled bogie unit according to claim 4, including one or more operating cylinders to act between the mounting bracket and the cradle, to move the cradle relatively between the lowered position of engagement and the raised lifting position, and in which the mounting bracket is capable of carrying out limited pivoting movement, during relative movement of the cradle to the raised lifting position, in order to adjust the weight transfer of the suspended plant, to be split between a pair of wheel sets supporting the chassis. 6. The wheeled bogie unit according to claim 1 and in combination with a further wheeled unit for supporting the opposite end of the plant chassis, in order to suspend the plant for transport therebetween. 7. The wheeled bogie unit according to claim 1 wherein the slide arrangement mounting the cradle moves along the plane of movement in a direction that is between 30�� and 45�� to the horizontal. 8. A wheeled bogie unit which is engageable with one end of a chassis of a treatment plant, in order to support that end of the plant chassis above the ground for the suspended transport of the plant, in which the bogie unit comprises: a bogie chassis; a front axle mounting a front wheel set and a rear axle mounting a rear wheel set to support the bogie chassis; a lifting cradle mounted on the bogie chassis and having a projecting end which is engageable with said one end of the plant chassis; an inclined support and guide surface provided on the projecting end of the cradle and engageable with an inclined lifting surface provided on said one end of the plant chassis, in order to suspend said one end of the plant chassis above the ground; and a slide arrangement mounting the cradle on the bogie chassis at a region between said front and rear axles for relative slidable movement along an inclined plane of movement in a direction of between 30�� and 45�� to the horizontal between a lowered position of engagement with said one end of the plant chassis, when the latter is standing on the ground adjacent thereto, and a raised lifting position in which the end of the plant chassis is lifted off the ground and is supported by the inclined support and guide surface of the lifting cradle, wherein the slide arrangement comprises: a mounting bracket via which the lifting cradle is slidably mounted on the bogie chassis at a position between the front and rear axles, the mounting bracket configured to pivot on the bogie chassis and enable the weight of the suspended treatment plant to be distributed between the front and rear wheel sets; spacers and clamping strips which mount an underside of the lifting cradle on the mounting bracket, allowing free lengthwise movement of the cradle relative to the bogie chassis; and one or more operating cylinders to act between the mounting bracket and the cradle, to move the cradle relatively between the lowered position of engagement and the raised lifting position, and in which the mounting bracket is capable of carrying out limited pivoting movement, during relative movement of the cradle to the raised lifting position, in order to adjust the weight transfer of the suspended plant, to be split between a pair of wheel sets supporting the chassis.
