Special Leyland Vehicles with Three-way Tipping Bodies and Power Hoists for the Refuse Bins._
FOUR MUNICIPAL refuse-collecting vehicles of . a, particularly .interesting. type are being constructed by Leyland Motors, Ltd., for the 'Singapore Conservancy.
In Die earliest ages of history it 'was the Oriental nations that led the civilization of the world, but now conditions are very different, and we find the Western peoples striving to eradicate some of the crudities of Asiatic existence. For in stance, in Engkind. sanitation has progressed in a marvellous fashion, but in the East the elementary measures have changed but little through the years, and the receptacles for the household refuse are still placed in holes in the roadside paths, sometimes, but not always, to be carried away by some inefficient means of transport. Now, however, the arrangements are being modernized and the Singapore Conservancy has effected a compromise between the native ideas and those of more modern birth, and the new Leyland vehicles will be employed on the collection and removal of the contents of the garbage bins. • The chassis employed differs but little
from the standard 4-ton G type. In the ordinary tip-wagon the pump-drive ir taken through a pair of spur wheels from the front end of tile gearbox, but in each of the new machines the drive easing is , extended upwards to house a third spur wheel, which transmits power through a horizontal shaft and flexible coupling to the crane mounted close behind the driver's seat-.
The intermediate gearwheel is free to slide on the, pump driving shaft, its movementbeing eontrolled by a lever. Backward movement of this lever slides the intermediate wheel into engagement with dogs locking it to its shaft, from which the hydraulic pump located on the near side of tlhe frame is driven by a chain. At the same time the gearwheel is brought. into engagement with the for'ward face of the lower driving wheel.
A forward movement of the lever engages the intermediate wheel with that on the crane driving shaft, and also with the rear face of the lower driving wheel, thus either the tipping gear or the crane can be actuated from the engine at will.
The lifting capacity of the crane is 15 cwt., and the jib has a working radius of 6 ft.
The knowledge of the existence of this type of vehicle will, no doubt, be welcomed by many users of motor vehicles who are engaged in other classes of work where the crane would prove of value.
