ASHLEY TAYLOR, AMII main exhibits at nexl

soc Inst T, examines the P C demonstration

FRESH progress in several sectors of the municipal world will be . apparent. at the vehicle and appliances demonstratibn to be held next Wednesday as one of the features of the Institute of Public Cleansing Conference at Scarborough. Apart from certain entirely new designs, there will be numerous detail improvements with a general trend towards higher compression of refuse loads and a strengthening of interest in dustless, or near dustless, opera

tion. '

This year the vehicle demonstration will take place at the Northstead car park, commencing at 9.45 a.m. Afterwards the various exhibits will be available for inspection until approximately 5 p.m. On the Thursday afternoon various units in the earthmoving class will be put through their paces at a site on the ScarboroughBurniston road. The main conference sessions will be at the Grand Hall, The Spa, Scarborough. - Among entirely new productions that will be seen is the Atkinson Monak Spreadmiser, an independently powered bulk gritter available in 51 or 61 cu. yd. capacity for speedy attachment to either platform or tipper vehicles. This design employs a four-stroke petrol engine with either manual or electric starting, the drive to the main conveyor belt and spinner being actuated by a hydraulic system. The Spreadmiser has the advantages of controlled density, adjustable spread pattern, and ready attachment to vehicles employed on general service at other times.

The conveyor belt is driven by a rotary valve which itself is driven either from the wheels or from the propeller shaft of the vehicle. A single spinner mounted at the rear of the body is used, this being variable in height and fitted with an adjustable trough which provides for symmetrical or asymmetrical spreading either to right or left. The Monak Spreadmiser is now in production and deliveries are expected to commence in the course of a week or two.

Atkinson's standard products that will be exhibited are the Pathfinder footpath gritter with four-stroke engine a Land-Rover/Austin Gipsy snowplough, and a trailer gritter.

The Rolba R-400 snowplough, which has not previously been exhibited in this country, will be demonstrated by Rolba Ltd. A medium-weight machine, similar in size to the Rolba-Unimog but of lower price, this design is intended for employment on country roads and on the outskirts of towns. It is a selfpropelled wheeled snow blower and snow loader of robust construction and high manceuvraSility. Hydrostatic drive is used instead of the conventional gearbox, and the rotary head can he tilted hydraulically to follow the road camber. The front axle which carries the working head is rigid, whilst steering is from the rear wheels; both axles are driven. The working • power unit is an aircooled Deutz diesel developing 80 b.h.p. at 2,200 r.p.rn, A suspended barrier packer will be featured on the new Shefflex Super Pack collection vehicle. Special bins

are not required with this design, which provides dustless loading with containers of every description. •The pendulating packers are top-hung, being suspended from the roof. The system provides for their actuation by the main loading and compacting units with-which the packers are synchronized. The booster is located midway between the end of the main hydraulic compression unit's travel and the front of the body. As the loading and initial compacting devices are operated at the time of the emptying of each individual bin the auxiliary boosters rotate downwards, so pressing down the refuse and maintaining the pressure whilst it is moved around and packed away to the front of the body. The machine to be exhibited at the vehicle demonstration

Continued from previous page will be the 25-cu.-yd. Super Pack on a Ford 7-ton chassis.

A 100-gal. gully emptier on a Harhilt electric chassis will be put through its paces by the Yorkshire Patent Steam Wagob Co., who will also show a 500-gal. emptier mounted on a Karrier Bantam chassis. Both these machines have been designed to meet the specific cleansing problems encountered in confined spaces in modern commercial areas, in these conditions small collection sumps being found in shopping precincts, multi-storey car parks and similar situations. Other Karrier/Yorkshire units to be seen will be a 1,000-gal. gully/cesspool emptier with servocrane and suction valve; the design provides for compression of the load in order to expel surplus water which is released to the roadside drains.

A special Type 6000 Sheppard

Meiller container-handling unit, designed for three particular functions, will be shown by Sheppard Fabrications Ltd. The duties for which it is intended are collection and removal of derelict cars, collection and servicing of 6-cu.-yd. refuse containers „from multi-storey flats, and lifting, transportation and unloading of civil engineering equipment.

This machine, produced to the order of the Barking Borough Council, will be mounted on a Commer 7-ton chassis. It has •an extended loading

platform and extra long.arms in order to deal with scrap cars, the maximum lift available at the arm ends being 3 tons. A second pair of lifting points is provided for handling the 6-cu.-yd. containers, the lift at this length being 6 tons.

The 6-cu.-yd _ container to be shown incorporates a twin-door loading aperture and a single torsion-barloaded discharge door,both being located on the container top. In order to manceuvre the container easily in confined spaces it is mounted at one end on a pair of wheels, at the opposite end there being a ball and coupling which enables it to be attached to a two-wheeled dolly for manual handling. The smallest unit in the Sheppard Meiller range, the Type 4000, will also be seen.

A feature not previously shown will be noted on the Ramillies 35 (Glover, Webb and Liversidge Ltd.). This is a quick-opening balanced rear shutter which swings up and under the roof. It can be opened or shut -easily with one hand and, when open, provides a measure of cover from the.. weather. This manufacturer will -also have available for inspection an example of the Marlborough toilet trailer, this time a smaller model of more univer= sal application than those which have been shown in the past. Features include self-contained fresh water and diluent tanks, flushing system and washbasin.

A further example of the Ramillies 35 will incorporate the Zoller airoperated dustless loading shutter and, in addition to the normal bodywork, an extralarge salvage locker behind the cab, so that even such articles as old settees and divans can be collected on the same round as general refuse. There will also be the Ramillies 20, the smallest of this manufacturer's range of continuous loaders and one which is easily rnaneeuvred. It will be carried on a Karrier Bantam 8-ft. 2-in.-wheelbase chassis with threeman cab.

Also available for examination will be a 25-cu.-yd. Dual-Tip with a compression plate that should increase the capacity by at least 20 per cent. The final item will be the Musketeer, this company's newest design, which is specially intended to.cleal with bulky refuse, such as large cartons, paper bags and shop waste. -The machine has a capacious hopper -with twin rotary impellers and will be exhibited with bin-lifting equipment for large_ containers.

Ramillies continuous-loading collection bodies of 50-cu.-yd. and 20-cu.-yd. capacities will be featured by Karrier Motors Ltd. and will be accompanied by a 35-cu.-yd. Musketeer. Karrier will further demonstrate the Yorkshire suction sweeper, first shown at the 1964 Public Works Exhibition, this being mounted on a Karrier Gamecock chassis and having a second oil engine to drive the suction system and scarifying brushes. Again on a Gamecock chassis will be a Yorkshire 800-gal. gully-emptier.

Among recently introduced cleansing appliances to be seen at the Exhibition will be the Model 85 scrubbersweeper, one of the Tennant range of industrial units which are distributed by R. S. Stokvis and Sons Ltd. In a 25-minute operation this machine can be converted to a power sweeper. Two 20-gal. tanks at the front carry cleansing solution which is fed on to the surface in advance of the forward scrubbing brush. The liquid' is sucked back into the machine again by the rear scrubber and stored in a 40-gal. recovery tank. A vacuum-system squeegee clears waste water, leaving the surface almost dry and ready for . immediate traffic. This model scrubs a 50-in. path.

Three other sweepers and the Erickson K-15 loader will be shown by this company.

As last year, models, pictures and film will be available to illustrate the MPL system of bulk refuse transport (Fawcett. Preston and Co. Ltd.). Further development of this plan has resulted in the production of a multipurpose range. The Type 1400,. now available, can employ existing vehicles with only minor modifications; Type 600 has been planned specially for use in blocks of flats or groups of multistorey buildings. The MPL static compression unit used for over two years at Hammersmith's Riverside depot regularly produces bales of 10 cwt. per cu. yd. density and the three MPL vehicles in use together move some 85 per cent of the total loadings.

A new design in the Dempster range, shown by the Powell Duffryn Engineering Co. Ltd., will be the Dinosaur HS, which carries largecapacity containers of various designs with weights up to l I tons; also available will be the model 13T. with a further 2 tons capacity. As is well known, the lifting equipment hoists a ready-loaded body on to the chassis, putting it down full or tipping it on arrival at the destination. There will be two versions of the Dempster Dump/baster bulk haulage compaction unit, one with self-loading arms for lifting containers of up to 6 cu. yd. and tipping into the vehicle body. Other offerings by this exhibitor will be the two Dempster Durnpster handling units. Among the Crushloads offered by the Eagle Engineering Co. Ltd., a 75-cu.-yd. body will be an outstanding feature. This design can be modified to suit a number of six-wheel chassis and on this occasion it will be exhibited on a Seddon. Bedford chassis will be employed for both the 50-cu.-yd. and 35-cu.-yd. Crushloads. As will be recalled, this design employs twin moving barriers to give high compression, clearing the hopper so as to obviate waiting on the part of the loaders. Final exhibit from Eagle will be an 800-gal. gully/cesspool emptier.

In action

A representative range of Pakarnatic collection vehicles, manufactured by Shelvoke and Drewry Ltd., will be seen in action. A notable new feature here is the mechanical bin loading equipment for standard types of domestic bins. Either singleor doublebin operation can be provided, on the 50-cu.-yd. and 35-cu.-yd. models but single only on the 20-cu.-yd. The lift required to place the bins in the cradles is only 22 in., the loading and return to the bottom position being entirely mechanical. Since the method employed does not necessitate the use of a special bin with hinged lid, it is not claimed to be completely dustless; but dust emission is stated to be reduced by at least 80 per cent when compared with tipping over the loading rave. The bin lid is not removed until lifting commences, then being held by the operator and replaced as the cradle is lowered.

A separate pump is used, the time cycle being about 7 sec. per bin with the single equipment. The manufacturers calculate that, with kerbside collection and two men loading, a rate of 200 bins per hour can easily be achieved.

Fall-back of the load is prevented by a new mechanically operated retainer plate to be shown by John Gibson and Son Ltd. on the 8112-cu.-yd. Pendulette collection body; in this way a clear hopper area is ensured after each compressing operation. This will be the smallest Gibson unit of the three to he shown and will be mounted on a Dennis Pax 7-ft. 6-in.-wheelbase chassis.

At the other end of the scale will be the 22/35-cu.-yd. Pendulum compressor, with container lifting attachment for to 11-cu.-yd. bins mounted on a Dodge chassis with Gibson sixman-crew cab. The compression barrier on this model is fitted with Continued from previous page automatic return control valve, so permitting unattended packing action. Operation of any of these units can be controlled either from the cab or the rear of the vehicle.

From Morris Commercial Cars Ltd. will cornea Morris FF.K140 chassis with power-assisted steering, carrying a Gibson Pendulum refuse collection body. Also to be shown will be the Morris/Darlington Litterette which is intended to deal with litter, problems in restricted places; it is manufactured by Bradburn and Wedge, using a' Morris 14 chassis with a timber, tipping body pf up to 10 cwt. capacity and a detachable triangular alloy-clad wood canopy. There is a single-screwhand-operated tipping gear. The Austin Motor Co. Ltd. will present an Austin FG.K100 chassis carrying an 800-gal. Eagle gully/cesspool erriptier.

Modern styling

One of the more recent additions to the range of Dennis Bros. Ltd is the 1,500-gal. cesspool emptier, introduced to meet a _demand for tanks of higher gallonage. Modern styling will be-seen on the machine to be demonstrated which, when mounted on the Dennisshort-wheelbase chassis, is easily manceuvrable. In the same class is an 80011,000-gal. gully , emptier with street washing equipment, the pump being driven from the top power takeoff and, using four washing feet, giving a wide cleansing spread. The wellknown Dennis Paxit 111A collection vehicle with two-stage compressing mechanism will be available: first with dustless loading equipment and secondly with a bulk container hoist in addition to the standard type.

Bedford TK chassis will be featured in each of the five units that will represent Vauxhall Motors Ltd. Bodywork will include a 50-cu.-yd. Crushload collector, an Eagle 800-gal. gully/ cesspool emptier, a Lacre suction sweeper-collector, a Yorkshire 1,000gal. gully/cesspool emptier and a Gibson 16/24-cu.-yd. Pendulum collector.

The Johnston suction cleaner, which has achieved wide acceptance since its introduction four years ago, is now available mounted on Austin chassis with fully tilting low-entry cab. Particular attention has been paid to variations in payload which may comprise a substantial quantity of heavy material or a very reasonable loading of leaves, paper and other sweepings of low weight but large volume. A second Johnston unit will incorporate a Dennis chassis on which will also be E16 shown the company's dual-sweep equipment. Johnston now manufactures and distributes the JohnstonAtumat high-pressure sewer-cleaning appliance which is a development of the original Atumat unit.

A recent modification to the 1244 Wayne power sweeper (Walker's Mechanical Cleansing Ltd.) is the incorporation of a sack : discharge system, as a result of which a 20 per cent increase in actual sweeping time is claimed since the machine does not need to leave the operating area in order to dispose of the collected material. Two front channel brooms increase the sweeping width and two side brooms provide for the easier clearance of congested areas. A long .wandering vacuum hose can be supplied, which facilitates the removal of dirt and small rubbish from beneath parked cars.

The Verro suction sweeper,. which has created a good impression at previous conferences, will again be demonstrated by Verro Ltd. and a number of new features will be seen on this occasion.

The well-known LeWin Mechanieal Orderly will be paraded by Lewin Road Sweepers Ltd.; this company will also show` the ,Brockhouse 31-cu.-ft. refuse bin, blow-moulded in highdensity polythene and weighing 10 lb. including lid:

A full range of road sweeping units will be brought to Scarborough by Lacre Ltd.,' among them the newest type with an independent threecylinder oil engine which drives brushes and-fan, so permitting work,

ing power to be controlled independently of the vehicle engine speed. From IL Young (Motors) Ltd. will come the Sturchluxe Glutton trailer sweeper-collector which is of straightforWard design, ,being intended for attachment to a ti actor and for operation by the p.t.-o. shaft. The Sturdiluxe rear-mounted brush will also be shown.

In parade David Brown Tractors Ltd. will be represented by a Model 990 in the vehicle parade, whilst a Model 880, with Danline rotary steel wire brush, will figure in the static display. Bech, Neale and Co. Ltd. will offer Norba system bodies of the continuous manual loading type: they will be seen on Dennis and Karrier chassis. Among items for ice and snow, control will be the Esse rubber-bladed snowplough, a product of Smith and Wellstood Ltd., Sisis trailer-spreading units of various capacities from W. Hargreaves and ,Co. Ltd., and gritting machines from Gloster Tractors Ltd.

A newcomer to the appliance parade will be Belos Gravely Ltd with light two-wheel tractors, snowplough, power brush and snow loader. William Bunce and Son promise a Schmidt rotary snow cutter on a Unimog chassis. Trailer sand and salt spreaders will come from Vicort Agricultural Machinery Ltd. and similar products. from Pickering and Sons (Dewsbury) Ltd.

Three-, fourand six-cylinder oil engines, suitable for a variety of uses,_ are to be shown by Perkins Engines Ltd.
