single-drive bogies has been developed by Scammell Lorries Ltd., and a Routeman Mk. II rigid eight-wheeler fitted with this equipment will be in Glasgow during the period of the Scottish Motor Show, which opens today. The device consists of twia air-pressure chambers, working at 110 p.s.i., which are linked by simple lever systems to the balance beams of the rear-bogie suspension.
When the cylinders are charged the front ends of the balance beams are forced down, thereby increasing the driving-axle loading, this increase being claimed to be 100 per cent when the vehicle is unladen. The load-transfer mechanism is manually controlled from the driving seat, and there is a warning light in the cab to indicate that the device is in operation. Air is drawn from the secondary reservoir of the main air-pressure system.
