Possibility of One or Two Entirely New Vehicles at Next Week's Institute of Public Cleansing Conference in Scotland : Distance to the Centre May Limit Amount of Heavy Machinery Shown
FORECASTS suggest that a couple of new vehicles of exceptional interest are likely to make their appearance at the Institute of Public Cleansing Conference at Aberdeen next week, but details were not obtainable at the time of going to press. As usual there will be a parade and demonstration of mechanical appliances on the Wednesday and on this occasion it will take place at Hazlehead. The once-popular moving-floor refuse collectors seem unlikely to be represented this time.
The demonstration of earth-moving equipment will be staged on Thursday afternoon at the Seaton site, Aberdeen, but this year it does not seem likely that so many units will be displayed as in recent times, the distance to the conference centre being something of an obstacle where transport of heavy machinery is concerned.
The main interest in the exhibits of Shelvoke and Drewry, lid., is likely to concern the 50-cu.-yd Pakamatic which is making its first appearance at this conference and will be seen equipped with the patent SD air-operated hygienic shutters. The chassis incorporates a Leyland I10-b.h.p. diesel engine, together with 10-ton rear axle and 5-ton front axle.
A crew cab, with four wide doors, gives comfortable accommodation for the driver and six loaders, there being low, built-in, steps for easy entrance. Vehicle width is 8 ft. and space within the body is 19 cu. yd. It will carry the maximum permissible gross load for a two-axle chassis, and has a directthrust hydraulic loading system. Easy discharge of the load is ensured by the 50 angle of tip.
In addition. SD Fore and Aft tippers will be seen, the loading flaps of the rear doors on these models working on the up and over principle, a notably
1330 simple system of operation appropriate to cleansing work.
With a 17-cu.-yd. body and Zoller dustless loading shutter, the Haller refuse collector shown by Glover, Webb and Liversidge. Ltd.. demonstrates a design which has achieved considerable success on the Continent. This model is one of a repeat order for the City of Birmingham in connection with that authority's dustlessloading programme.
Ground loading, a high degree of compression, and simplicity of mechanism, are combined in the Blenheim 18-24-cu.-yd. collector which is based on the Glover I.oadmaster. This
machine will be mounted on a Karrier heavy-duty chassis with crew cab. This company's Dual Tip collectors are represented by 25and 12-13-cu.-yd. models, the junior type being of small dimensions for use in crowded city centres and backways. The Karrier Bantam chassis with coach-built crew cab is used for this particular unit, which is destined for Manchester.
In an entirely different class from the foregoing will be the offering of Scammell Lorries. Ltd.. the principal feature of which is the Scarab threewheeled 6-cu.-yd. side-loading refuse collector, particularly suited for work in confined spaces or dealing with lightly loaded rounds. This unit has a • four-speed gearbox, pressed-steel frame and coil-spring front suspension. The body, which can be fitted for either power or hand tipping, has two loading ports on each side and twin hinged rear doors. With a turning circle of under 20 ft. these vehicles are extremely manoeuvrable. The standard power unit is a 45-b.h.p. petrol engine but a Perkins 55-b.h.p. diesel engine is available as an alternative.
First shown to the I.P.C. at the 1960 conference demonstration, the Tippax body from Dennis Bros.. Ltd., carries a 20-cu.-yd. forward and rear tipping refuse body, the actual machine being one supplied to the Aberdeen County Council. In order to convert it for use in a different sphere a simple set of equipment can be obtained which will facilitate the dustless discharge of bulk containers.
The Dennis Paxit III, which will also be seen, follows the well-established design of this series, having automatic continuous loading collection, with hand-operated dustless loading for small bins and for twice-weekly rounds. Sets of power-operated dustless loading equipment for 2.5-cu.-ft, or 3.2cu.-ft, weekly collection bins are available, as is power equipment for bulk container dustless discharge. An example of the Paxit II collector, destined for Ceylon, will also be shown.
Main improvements in the range of John Gibson and Son. Ltd., concern the hydraulic loading lines of the pressure system, a prototype of which was to be-seen at last year's demonstration. The load ram is now mounted on the vehicle chassis, being connected to the rear barrier by means of a hinge link into which a hook on the barrier fits. Under the old system this ram was carried on the body only, the long
lengths of hydraulic piping resulting in a serious loss of pressure.
The longest run of pipe is now zipproximately 7 ft., from the pump to the end of the load ram. Thus it has been practicable to reduce working pressures, so saving wear and tear on valves, pumps and couplings. On discharge, by means of the hook mentioned, the rear door uncouples itself automatically from the load ram connection.
By reason of an interlocking arrangement the vehicle can be tipped only when the door is in the extreme rear position. A Gibson Pendulum 16-24cu.-yd. compression refuse collector will be demonstrated on the Bedford riK 151-in.-wheelbase 7-ton chassis
with Gibson crew cab. Another Pendulum will be seen on a Karrier Gamecock chassis and on a Commer 7-tonner there will be a third Pendulum, this time with a Gibson-Paladin bin lifter at the rear.
An air-operated dustless loading shutter is featured on the latest Clean-. load collection body by the Eagle Engineering Co., Ltd. This is a 12-24cu.-yd. model with a continuous loading drum revolving at 4 r.p.m. The rear door, which forms the loading hopper, is raised for the discharge of the drum contents. The drum itself is lagged for quietness and is covered by a streamlined glass-fibre shroud which has detachable alloy panels for inspection and maintenance. The Eagle unit mentioned is another of those intended for employmentin Birmingham and is mounted on an Austin 7-ton chassis with crew cab.
A notable feature of the Eagle offering is the Compressmore 16-24-cu.-yd. collector body, which has the floor sloped at the rear to give a reduced loading line, the rear surface being covered with a special quality of corrosionand abrasion-resistant steel. The compression plate forming the loading hopper is operated by a hydraulic ram mounted at roof level, the plate itself being retracted upwards into the roof when the body is emptied by use of the front ram. A stabilizer is fitted to give added safety when tipping on rough ground. The chassis employed in this instance is a Bedford TK.
Several outsize machines will be shown by the Powell Duffryn Engineering Co., Ltd., notably the Dempster Dumpmaster DB 30, which is a compressing bulk transporter of 30-cu.-yd. nominal content and 75-cu.-yd. refuse capacity, carried on an A.E.C. Mam.moth Major eight-wheeled chassis. Next comes the Dempster Dinosaur 22,000T transfer loader and transporter, mounted on an Atkinson sixwheeled chassis. Containers from 8 to 30 cu. yd. capacity come within the scope of this unit, which can set its own body down on ground or dock and will lift it again for transport purposes.
The Dempster Dumpster hoisting unit, which can handle containers up to 15 cu. yd., will be shown on a Bedford forward-control chassis. There will also be a Dempster Dumpmaster on a Thames Trader, fitted with a County third axle.
In addition to the examples mentioned earlier, the products of Karrier Motors, Ltd., will be demonstrated separately by that company. There are three such models, the specialized body work in each case being by Glover, Webb and Liversidge, Ltd. One is a Blenheim 22-30-cu.-yd. compressing vehicle, the power unit employed being the Rootes 3-cylindered diesel engine. Alternatives for this model are the Rootes 6-cylindered petrol unit or the Perkins Six 354 diesel engine. Specimens of these engines will be seen. on the other Karrier exhibits.
The well-known Jekta telescopic body, a product of Walkers and County Cars, Ltd., will be making a reappearance in the arena, the particular example being seen on a Leyland Octopus chassis. Initially the Jekta design was being made with a capacity of 21 cu. yd. but, as in other spheres of the transport world, sizes tend to increase and current orders are calling for 34 cu. yd. A particular feature of the horizontal system of discharge is . that no extra load can be imposed on • the rear axle, an important consideration when working on uneven ground.
Pedestrian-controlled electric trucks for street cleansing come from the Stanley Engineering Co., Ltd., who will be exhibiting an end-tipping orderly, also the Manulectric 4 which is designed to handle a dozen square bins of If Cu. ft. capacity each. For the first time this company will demonstrate a manual two-bin street orderly which is built in light alloy and carries a pair of 31-cu.-ft. glass fibre bins which weigh 16 lb. each, or approximately half the weight of galvanized bins of the same capacity. Recent improvements in the orderly are the use of two steel-reinforced aluminium skids at the rear and a single castor wheel in front in place of the four legs previously employed.
Gritting equipment is a speciality of Atkinson's Agricultural Appliances, Ltd.. which company will make a special feature of a trailer gritter which has a hopper capacity. of 2 tons and will distribute grit, ash, sand or salt, over variable widths from 6 to 40 ft. As an alternative to steel, the bodywork can be supplied in glass-fibrereinforced plastic. A similar alternative is available with the Atkinson chassis-mounted bulk gritter which is to be displayed on a Thames, with the spinners situated forward. An hydraulic • valve is incorporated in this machine to revdrse the belt for rear off-loading.
From the wide range of rotary snow ploughs by Rolba, Ltd., which comprises machines with capacities from h.p. to 300 h.p., three will be-shown at Aberdeen. The trio includes the Rolba-Kloeckner which is believed to be the largest snow-blower ever shown at a British exhibition. This is one of two similar machines in possession of the Aberdeen County Council and has a clearing width of 8 ft. 4 in., which can be increased if necessary to 11 ft. 6 in., With a capacity of 1,500 tons of snow an hour. Intended for use on trunk roads, the Rolba-Kloeckner incorporates an air-cooled 90-h.p. transport diesel engine, there also being a 180/200-h.p. 12-cylinder air-cooled diesel engine for plough operation carried in the van body.
This star performer will be supported by the Rolba Snow-boy, a pedestrianoperated blower which is stated to perform the same work as 100 shovel men and will load a 5-ton lorry within three minutes. There will also be the Rolba 2012, which is a self-propelled unit with driver's cab and centralized controls.
In the road sweeper class there will be exhibited the Bedford-Lacre sweeper-collector and the Bedford1,acre suction road sweeper-collector. The latter is built up on the Bedford KFS forward-control chassis, being available with a variety of alternative equipment to meet the differing needs of local authorities and to deal with either normal usage or dual carriageways and one-way streets.
The exhauster unit is located behind the cab. A 19-in, gutter collector brush, on the left, is connected to the dirt container by the suction hose whilst in front is an extension brush, set at an angle to the chassis, which feeds the collector brush, so increasing the effective sweeping width to 6 ft. The welded steel plate dirt container incorporates a water tank in the bottom.
From Lewin Road Sweepers, Ltd., will come the Sweepmaster roadsprinkler-sweeper-collector which is fitted with a vertical wire scarifying brush and has controllable high-pressure water jets fore and aft of the brushes. Tipping and lowering of the 3-cu.-yd. capacity Lewin Mechanical Orderly sprinkler-sweeper-collector is by push button control. The sweeper is fitted with a main traverse rotary brush and a vertical channel scarifying brush, both raised and lowered independently by electro-hydraulic button to give adjustment to suit varying road conditions.
Among the specialized units also to be found at the demonstration will be an Eagle 800-gal. gully emptier with a tank divided into two compartments, one of 530 gallons for sludge and the other of 270 gallons for clean water. An example of the Dennis range will be provided in the form of a 1,400-gal. cesspool emptier.
A David Brown 50TD shovel is to be demonstrated by David Brown Construction Equipment, Ltd. This is a tracklayer unit carrying a bucket of 1 cu. yd. struck capacity. The engine develops 35.5 drawbar h.p. at 1,600 r.p.m. Lifting capacity is 4,000 lb. and lifting time from ground level to maximum height of 10 ft. 6 in. is 5.6 sec.
Three vehicles will be demonstrated by the Ford Motor Co., Ltd., all with bodywork by Eagle. The first is a 3-cu.-yd. refuse collector on a Thames 15-cwt. chassis with two covers on each side. Hand-operated screw or manual hydraulic gear tips the body to an angle of 45 degrees. A.Compressmore body of 12-20-cu.-yd. capacity will be seen on a 5-ton Trader chassis with Ford oil engine. The third unit is an M50 800-gallon cesspool emptier, again on the Trader chassis.
