AS mentioned in a recent article, the Paris municipal council is making great efforts, it the moment, to modernize the collection of domestic refuse in the French capital. Although, in normal circumstances, this workis carried out by contract, the council itself has for some timefbeen conducting successful experiments with Faun lorries, built under licence by Somua, whilst S.I.T.A., the big municipal-contracting concern, is employing the Rey hydraulic system, which we have
already described. •
Another contracting company, the Cie-Generale des Entreprises Automobiles, has just placed in service a new type of self-loading vehicle. Designed and constructed by Messrs. Fernand Geneve, 188, Rue du Chateaudes-Rentiers, Paris (13e), the tippingbody specialists, this machine presents several points of interest. The body, entirely closed, is mounted on a standard Latil B.6-type chassis and the loading mechanism is arranged at the rear.
Loaders throw the refuse into a skip, which is then hauled up by chains and tips its contents on to an internal loading platform at the top of the body. A steel disc operated by two double-acting hydraulic rams completes the process by forcing the rubbish forward off the platform into the interior of the body. The movement of the disc is conveyed to the chains which raise and lower the skip.
The whole operation is thus automatic and is controlled by valves similar to those employed in tipping the body. When the lorry tips its contents into justments to the loading gear are being effected.
The Geneve system has been found of particular utility in collecting refuse at the Paris central markets, where the streets surrounding the market halls are extremely congested and an enormous quantity of litter has to be cleared daily. During a week's trial , under official observation, one of these Geneve-Latil lorries, with a capacity of 12 cubic m., collected 5,830-6,600 kilogs. of refuse per day. Time saved represented about 15 per cent., as compared with an ordinary hand-loaded lorry of similar capacity.
Our Paris representative watched one of these vehicles at work and was favourably impressed with the speed and cleanliness of the operations. The loading orifice extends to the full width of the body and when collecting refuse from the ground, as in the case of market litter, two loaders can work at the same time. When the vehicle is travelling, the loading door is always closed to prevent the escape of dust.
