PARADE By Gordon Crabtree
THE Institute of Public Cleansing Conference, demonstration and exhibition which takes place at Bournemouth from May 23 to 26 will be one of the most important in the conference's 74-year history. Not only because of current interest in environmental factors and on account of the wide range of vehicles and appliances to be shown, but also because this year the exhibition's international counterpart will be held in Prague just one month later (June 27-July 2). More than 100 firms displaying and demonstrating their ranges will be hastening to Czechoslovakia directly after the Bournemouth show in order to gauge the prospects of sales on the Continent.
Among the vehicles on display at Bournemouth will be a range of suction units from General Descaling Co Ltd, of Worksop, Notts, manufacturer of modular units of a capacity which enables them to be fitted to most 10to 13-ton chassis. Suction lift depends on ambient conditions and is in the 16 to 28ft range. The standard work rate is 50 Cu ft a minute for most sludge consistencies, and solids up to 2fin. diameter can be lifted. The metal tank has a special corrosion-resistant lining and a highpres sure agitator is fitted to break up sludges and there are separate sludge and water tanks as well as a syphonic float-type water sludge separation and discharge system. Tipping action provides easy emptying and a power-take-off or auxiliary engine drive can be fitted.
Tipping-hopper trailer
To assist sewer cleaning General Descaling also produces a tipping-hopper trailer with a capacity of 250 gallons. Use of this eliminates the need for roadside deposits awaiting collection.
Rolba Ltd, of East Grinstead, Sussex, will be showing its new R-200 snowplough which fills the gap between the pedestrianoperated Snow Boy 2005 and the medium-sized Rolba R-400L. The R-200 is built on a special chassis with a comfortable, purpose-built cab giving the operator all-round visibility. Powered by the newtype 127 66 hp VW industrial petrol engine through a manual six-speed gearbox and a hydrostatic transmission, it can be driven as a normal vehicle with the conventional gearbox. However, during snow-clearing opera
tions the hydrostatic transmission is engaged giving infinitely variable control over the forward speed, enabling the operator to control the machine by a single lever.
The rotary plough is built according to the well-known Rolba two-stage snow clearing principle with cutter and blower. It has a 270 deg turntable chute for which an hydraulically controlled loading chute extension is also available which enables snow to be loaded on to a lorry at a very high rate. This addition to the Rolba range has been designed not only to give the operator comfort and simplicity of controls, but also to give unrestricted access to engine, gearbox and all other working parts.
Dennis Brothers Ltd, of Guildford, Surrey, introduces the Dennis /Molex cesspit emptier which is a significant development in the field of sludge and slurry clearance. A non-pressurized emptier, it can handle heavy or dense sludge at high speed from below ground level or at distances up to 250ft from the cesspit. The sludge is drawn directly through an advance heavy-duty pump which maintains initial suction power and thus enables full use of tank capacity.
Another recent addition to the Dennis range is a rear-loaded refuse vehicle which takes the backache out of dustbin emptying. A low hopper at the rear holds 17 to 20 dustbins' contents before it has to be emptied into the body of the vehicle. In 12 to 15 seconds the entire contents of the raised hopper can be swept into the body by a descending plate.
Dennis engineers have designed a new mini refuse collector which also makes its debut. Based on an 8ft wheelbase chassis and powered by a Perkins 4.236 diesel engine, it is only 6ft 6in. wide and can negotiate narrow entrances and country lanes. It is a continuous loading vehicle with a single cab to accommodate the driver and crew of two. Body capacity is 20 Cu yd, it has a full-width hopper of approximately 1 cu yd, and discharge is by tipping.
Multilift Ltd, of Shrewsbury, Shropshire, will be showing a refuse compactor system which has a claimed advantage over normal compactors which do not really commence until the container is full. The Multilift system provides a Double-Crush method. The refuse, when first emptied into the hopper is compacted against the plate, and the pre-compacted refuse is then forced forward into the container. The DoubleCrush can handle all types of domestic and industrial refuse. Oil-drums and the like are crushed to approximately one-tenth of their length before being forced into the container. This crushing system gives a higher performance than is usual from refuse conveyances.
Sheppard Equipment Ltd, of Thetford, Norfolk, with a demonstration of its latest advances in waste disposal equipment is bound to attract considerable attention with its latest model of the Sheppard Meiller. Although lighter in weight, this container iandling unit is as robust as ever and built Dr prolonged work in tough conditions. It Icorporates the Sheppard hydraulic sysem, which has two-speed lowering of conainers and single-lever control for fast and imple operation. The container carried by he Sheppard MeiIler will be from the firm's onvertible range. With this range, an open ontainer is converted to a larger capacity losed container by the addition of a etachable-top assembly.
The Sheppard Rolonof Two, which had a ood reception when introduced last year, rill also be on the stand. This unit will ick up a loaded body or container, empty and put it down again. This is done uickly and simply by means of a central ft arm, powered by Sheppard MeiIler hydaulic rams. There are no cables or winches
the system. A specially designed ook at the end of the lift arm engages with n anchorage point on the container body, nd this method of attachment permits istant and automatic coupling. All opera
tions are carried out by the driver from his seat in the cab. The Rolonof Two can be used with different bodies for different jobs such as those of gritter, a cesspit emptier, a tanker and so on.
Shown by Ronald Perham Ltd, of Clapham Road, London SW9, the Seddon / Shark bulk refuse collection vehicle and its Hush Packer is sure to attract attention. The Shark is built at the Beaumaris factory of Laird (Anglesey) Ltd and is a continuous-loading compression vehicle. The bin-lifting attachment is self-contained with its own individual hydraulic circuit driven from a gearbox. Only four bolts hold the equipment to the back of the vehicle and the hydraulic connections have quickrelease, self-sealing couplings. Fitting or dismantling of the equipment ,takes only half an hour and the existing Seddon /Shark can be converted for approximately £950. With the vehicle the time cycle for lifting containers takes only 20 seconds. In fact the standard Seddon /Shark bin lifter with a three-seater cab costs only £500 more than the standard Shark refuse collector with a crew cab and with the same 50/60 cu yd capacity body. The equipment is mounted on the Seddon 13 4-ton-gvw 12ft 6in. wheelbase, thus making a most manoeuvrable vehicle.
Three vehicles from the Whale range of tankers which are manufactured by Fusion (Bickenhill) Ltd, of Leicester Street, Walsall, will be on show. The 1200gal gully/cesspool emptier is available from stock. This machine is being supplied to R. J. Evans and Kitchen Ltd, of Birmingham, which will be stocking in addition several other Whale tankers. This vacuum tanker on a Ford DT 22144 195in. wheelbase and 6 X 4 chassis is powered by twin RAL 1310 exhausters giving a combined output of 240 cfm, The capacity of the tank coupled with high pump performance provides a very economical operation with 'rapid collection and impressive discharge rate.
The 2250ga1 Eccentric sludge spreader which was originally custom-built for Poole Corporation is designed for off-road use. The tanker is equipped with an hydraulically driven Holz HSP 100 Eccentric worm pump and the company claims it is the first to develop this form of hydraulic operation. Designed to spread sewage on the land, the tanker has twin rear spreaders operated pneumatically from the cab, which is said to obviate "pooling". The 1200gal combined gully/cesspool tanker is on a British Leyland Boxer BX 1200 131in. chassis and incorporates many new features.
Yorkshire Vehicles /Eagle Engineering Co Ltd, of Pepper Road, Leeds, were merged last year and now produce among other vehicles the Yorkshire suction sweeper which is the only one with load compaction capability, permitting refuse to be compressed during the work cycle. Partial loads can be compacted to enable optimum hopper space to be utilized and excess water content to be drained off. The Mark IV sweeper which is to be exhibited is said to be the quietest of its type available in the UK and can be fitted to most makes of chassis. The Eagle Compressload 7 refuse collector is continuous loading and the tipping is by ejection discharge, a factor contributing greatly to stability of the vehicle when working on uneven ground. The Yorkshire range of combined gully /cesspool emptiers comes in tank sizes of 800, 1000, 1200 and 1500gal capacity. Each one incorporates an hydraulically operated pusher plate mechanism to compress the load of sludge and allow for water to be drained into the surplus compartment for draining into the sewer. The suction pipe can be operated at the offside or at the rear as the crane arm has a 340deg working radius.
The Eagle Crushload Mk II refuse collector will give a loading capacity of 35 or 50 cu yd of refuse. The patented loading mechanism is continuous and fully automatic. The action of the loading mechanism crushes the refuse before entry into the body where further compaction takes place. Discharge is by high-angle tipping. Another vehicle to be shown, the Eagle Pendulum refuse collector, is a simple compression unit and is available in payload capacities also of 35 to 50 cu yd. The compression ram is mounted horizontally on the main vehicle chassis frame and is actuated by the driver. A press button fitted to the rear of the vehicle allows the loader to signal the cab each time a compression cycle is required.
Smith's Electric Vehicles Ltd, of Team Valley, Gateshead, Co Durham, is to show four vehicles. These include a Cabac 75 cleansing vehicle fitted with an end-tipping open body having extendible sides and destined for the London Borough of Waltham Forest. This vehicle is one of two to be used to service a street market approximately one mile in length and will accommodate 4 cu yd of refuse in the normal position so that an extra 3 cu yd can be loaded when the sides are raised. The front and rear bulkheads are to the full height and the vehicle features a broom and tool rack constructed in lin. square mesh material which is mounted on the offside of the walkway and so causes no visual obstruction to the driver.
End—tipping, side loader
The Cabac 65 is a vehicle fitted with an end-tipping, side-loading body and will also be on view. It has an offside walkway cupboard with glazed panel above and two extra crew sea,ts fitted in the walkway. There is bound to be a great deal of interest also in the Cabac 75 vehicle with a sideloading, end-tipping body of 34 Cu yd capacity. This is one of seven vehicles to be supplied to the London Borough of Croydon and is fitted with a water tank of 20gal capacity for use in refilling weed-killing apparatus. The vehicle is fitted with side equipment lockers in the spare space of the battery carriers and has a broom and tool rack along the centre section of the body. The fourth vehicle to be shown is the Cabac 65 fitted with a flat deck and centrally hinged chassis covering 15 bins and similar to a vehicle recently supplied by the company to South Shields Corporation.
Four new models from Powell Duffryn Engineering, of Glamorgan, will be making their first public display appearance. The
Packslave I is a new version of the stationary packer in this range with a capacity between that of the PowerMite and the Packslave II. It is ideal for waste clearance through compaction at supermarkets, large stores, hospitals, offices, factories, industrial and public buildings. It gives fast packaging of waste in compacted form into a detachable container which is removed by a Dinosaur, Skiplift or similar vehicle.
16 tons crushing force The Packslave I has a rated capacity of 14-cu yd and a displacement of 1.28cu yd and the heavy, steel packing plate transfers waste from the loading hopper into the container with a crushing force of 16tons. The packer head overtravels 141in, to keep waste clear of the container opening. The operating cycle is 28sec and the vehicle will deal with 165cu yd of waste an hour.
The Skiplift II is a new version of the established Skiplift container handling system which can be used with a variety of skips. Among the improvements are an easier chassis installation layout, a shorter overhang which makes for greater manoeuvrability and smaller turning circle, and a more sophisticated hydraulic power system.
A new metricated version of the PowerMite has been produced and the opportunity taken to incorporate refinements which will meet requirements for both the British and Continental markets. All three sides of the power pack compartment have been enclosed by metal panels. The control panel is countersunk within the packer to reduce vulnerability to damage.
The Transpack 6 stationary refuse packer compresses large volumes of waste at high speed into a container or trailer. It has a charging box of 5cu yd capacity, and when loaded with waste a packer plate with a thrust of 45tons moves through the box to transfer the waste into the container, overtravelling 30in. to get maximum compaction. The full packing cycle takes 33sec. Power is from a self-contained pack with a 25hp motor with push-button automatic controls which gives single cycle, timed cycle or continuous operation.
To complete the display there will be a Dinosaur, the vehicle which can pick up loaded containers, haul them to the tipping site and empty them, all the operations being controlled by the driver without leaving his cab.
Harbilt Electric Trucks and Vehicles, of Market Harborough, Leicestershire, will have on display for the first time examples of a new series of driver-operated cleansing vehicles which range from handy 1-tonner with two-man cab up to a 3-tonner sixseater vehicle with a host of optional extras. The 4000 series is available in lowor high-speed versions with either a standard 3cu yd end tipper body or a 12-bin fixed body, and a range of as far as 30 miles.
The 5000 series has a threeor five-crew cab, tipper or bin-type bodywork, a gross vehicle weight of 86cwt made possible by the new heavy-duty front axle designed to accommodate the larger cab-load anticipated, a carrying capacity of up to 50cwt (with 31cu yd volume) and a range of 35 miles.
The 6000 series provides all the latest requirements, with a carrying capacity of 3tons upwards; four-, fiveor six-crew cab, washing facilities, broom and clothes cupboards, an auxiliary power circuit (independent of the traction battery) to supply flashing beacons, heaters, and demisters, as well as screen washers, electric kettle point, spray-pack lockers and many features never before offered on any electric vehicle.
Bin-type option
Other exhibits will be chosen from the comprehensive Harbilt range of six driveroperated and two pedestrian-controlled vehicles with either end-tipping or bin-type bodywork. Of the driver-operated vehicles, model 916 has a payload of 1.25tons, a speed of 12mph on level ground, and a range of 18-20 miles depending on conditions and battery capacity; it can operate successfully on duties away from the vicinity of the central depot.
Shelvoke and Drewry Ltd, of Letchworth, Herts, will be showing for the first time a Revopak series 15 /20 refuse collection machine which has been designed around the company's own SD purposebuilt TSR-type chassis on an 1 lfl 9in. wheelbase. This vehicle has a gvw of 14tons. One of the special features of the chassis is the SD two-door cab which provides accommodation for the driver and four loaders. Driver comfort is also catered for by the provision of power-assisted steering and full air-braking. The Revopak mechanism is common to that of the other two Revopak models which will also be exhibited.
The Revopak series sets a new standard of efficiency and silent operation. The TSR is particularly impressive when handling refuse in sacks whether of paper or plastic, and also light, bulky trade types of refuse. The hopper clearance is such that the rotary mechanism cannot be beaten by any normal team of loaders. It is therefore fair to say that under most conditions collection can be described as continuous. However, if the nature of the collection is such that intermittent loading is advantageous there is in-built facility in the Revopak for this type of collection.
William Bunce Ltd, of Swindon, is not revealing pre-show details of the new demountable gritting machine and new multi-purpose versatile tractor unit for use on footpaths. This tractor unit can be attached to salt spreaders, snow ploughs and sweepers which the firm supplies tc make them self-propelled, rider-operated units.
Code named Unit Two, a new ride-or suction sweeper from Melford EngineerinE Ltd is to be officially unveiled at the show Designed for use in precincts, subways walkways and other restricted areas the Melford Unit Two Precinct is 8ft 8in. long, 4ft 3in. wide with a turning circle between walls of lift 6in. The machine can sweep up a 25 per cent gradient even when loaded to lton. Hopper capacity is 1.3cu yd and is constructed from glassfibre reinforced plastic to reduce weight and corrosion. Tipping height is to the European requirements of 1300mm (4ft 3in.).
Two forward-mounted brushes are fitted, enabling the machine to sweep interior and exterior 90deg angles. Once moved into the path of the machine, sweepings are pulled up a large diameter suction pipe into the hopper. Suction even by Melford standards is extremely efficient. Cleaning is by hydroprecipitation and, after washing, "cleaner than-clean— air is exhausted to atmosphere.
Drive is automatic hydrostatic to the centre front wheel, providing speeds from 7.5mph to a travelling maximum of 30 mph. Power is supplied to drive, axial fan and other driven components from a 1600cc ohv ic engine, with a choice of propane or petrol fuel systems.
The driving position is centre-cab, with exceptional all-round as well as forwardbelow vision. The cab is fitted with a sprung seat which, with rubber suspension front and rear of the sweeper, provides a high level of driver comfort. All main controls are grouped and within immediate reach of the driver.
An external wanderhose, a feature of the current Melford Reliant sweeper, is also part of the basic equipment fitted to the Precinct. However, in the Precinct machine the hose is permanently fitted and a new mechanism provides a speedy and positive method of bringing the hose unit into operation. Tyres are 6.70 x 13 eight-ply rating commercial and the gvw is expected to be approximately 4420Ib with an unladen weight of 1981b.
Demonstration tour The sweeper will commence a countrywide demonstration tour in June after its Bournemouth debut and production is due to begin in the autumn. The price is expected to be less than £4000 when deliveries commence towards the end of 1972.
Timed to coincide with the Bournemouth show is the first appearance of a new design of bulk road-gritting machine developed by Econ Engineering Ltd, of Ripon, Yorkshire. Termed the Bantam it is a 2/3 cu yd capacity bulk hopper unit, demountable or permanently mounted with a rapid unloading facility of simple yet highly effective design.
Power for the feed conveyor belt and spreading spinner drives is derived from the vehicle's own tipper pump (up to a predetermined horsepower) or from a separate hydraulic input or diesel engine as alternative power sources. Econ has already supplied a number of these new machines to councils for evaluation,
The Bantam machine was designed basically as a lightweight unit for fitting on or to vehicles not requiring an hgv-licensed driver. To facilitate rapid discharge after gritting or during stand-down periods the discharge chute at the rear of the machine is removed entirely; two pins only securing it to the hopper (which acts as the volume regulator) can be swung open by tipping the vehicle together with the hopper in the normal manner. It is only a matter of minutes to refit the chute, no adjustments being necessary. Self-seal hydraulic hose couplings provide an easy plug-in to the existing vehicle system and are just as easily snapped back on disconnection.
One further special feature on this machine is the inclusion of a new, synchronized belt-tension system which ensures that the belt runs absolutely in track and at the correct even tension.
Other standard design principles are incorporated in the Bantam. These include symmetric or asymmetric spread options up to 36ft road width, variable volume regulation down to foz per sq yd and unit construction of all working parts on a single sub-assembly for easy removal and maintenance.
An addition to the Atkinson's, of Clitheroe, range of clearance equipment will be seen during the vehicle demonstration run. The City Gritter is designed to be the answer to snow and ice problems in city squares, urban roads and country lanes where space is at a premium. Mounted on a long-wheelbase Land-Rover, it has extra manoeuvrability, is easily transportable, independently operated and has large load performance. For ease of loading it is fitted with removable jacking stilts.
In addition Atkinson's are now producing the Clearway, for clearing roadways runways, etc. Developed by Dunlop Ltd, it is exclusively manufactured for world-wide distribution by Atkinson's and can be towed by any tipping vehicle operating on the principle of collecting and scraping mud, snow, slush or sand from the ground surface and conveying it by belt into the vehicle body.
Also on show will be the Atkinson Shark refuse collection vehicle but fitted for the first time on a Leyland Boxer chassis with continuous revolution, the Shark achieves a compression ratio of four to one by crushing and shredding with a rotating drum: Among its many advantages are fast, continuous loading with no bridging or stoppages and a rapid intake.
