on cleansing progress
by Ashley Taylor, AMIRTE, Assoc lost T THE cleansing officers and elected representatives watching the vehicle and appliance demonstration at the Institute of Public Cleansing Conference on Wednesday, will see some interesting improvements although few changes appear likely in basic design. Vehicles and appliances will be shown at the Sheepcote coach park, Brighton, all day on Wednesday and on Thursday until 1 p.m. There will also be a display of earthmoving equipment on a neighbouring site during Thursday.
After a long and successful run with the G, TG and SA series, Lacre Ltd. is to show a completely new sweeper with a shorter wheelbase. A fresh development is also likely to be included among the exhibits from Shelvoke and Drewry Ltd.
With a wheelbase of 120in. the new Lacre TG Compact suction sweeper has a turning circle of 40ft and a higher payload of 6 tons 4cwt. For the purpose of achieving a faster sweep, suction power has been increased by 10 per cent. An atomized water spray is incorporated so as to give dustless operation. A new compact sweeping mechanism has been designed which incorporates a combined brush and nozzle. Load spillage through the suction tube is eliminated by use of a supplementary control that can be operated to blank-off the tube when necessary.
Designed for the transfer of refuse from the city depots to disposal sites, a 63 cu.yd. bulk unit has been prepared and is likely to be shown by Glover, Webb and Liversidge Ltd. This unit will be seen on a Mammoth Major chassis with which the gross vehicle weight is 26 tons. Loading from hoppers or mechanical equipment at the transfer station is through apertures in the roof which are closed by hinged doors for the journey. At the discharge point the rear door is raised hydraulically and the contents ejected by means of a moving floor.
For the same kind of work Hoynor is offering a bulk refuse tipping trailer which is built to a body length of 26ft 6in., being constructed in lOs gauge alloy sheet with a +in. alloy sheet floor. To facilitate discharge the body is tapered with a 5deg angle sloping floor. Refuse collection vehicles can be unloaded directly into the trailers which when full can be collected by a tractor that has brought in an empty trailer from the disposal point. Some 30 of these trailers are being operated by Robert Deards Ltd. under contract to the GLC.
A Gibson bin lifter, never previously exhibited in this country, is to be demonstrated by Ronald Perham Ltd. This unit has been designed to collect 24 cu.yd. containers in addition to the widely used 1+ cu.yd. design. The larger container is elliptical in shape, the falling load on discharge being spread over the full width of the vehicle. The full height of the bin has been retained. The Gibson special lifting equip
ment is designed to raise 25cwt and is arranged for mounting on any suitable longwheelbase chassis. As the Gibson system employs intermittent compression there is no likelihood of the contents of an extra large container interfering with the motion.
In addition to the bin lifter Perham will also show its now well-known Shark refuse collection unit with dustless loading fittings. This machine employs a rotating drum mechanism with a form of rubber insulation to keep noise to a minimum. The unit to be shown is equipped with Zoller bins but equipment for the Oschner can also be incorporated. There is, of course, available an ordinary rear door for standard bins. The Shark will be mounted on .a Seddon chassis.
From Belos Graveley Ltd. will come the Squirrel sweeper-collector for litter. This machine is coupled with a motive unit that is fitted with the company's recently developed fully glazed cab. The overall width of the body is 401n. and the maximum sweeping width is 48in. Choice of either 10 h.p. petrol or 8 h.p. diesel engine is offered. The Swiftamatic 8 transmission provides four forward and four reverse gears. In addition to the main sweeping brush there is a feeder roller that supplies a secondary lift for difficult items. There are two water sprinklers and a tank holding 30gal.
Snow clearance requirements in some variety will be featured by William Bunce
and SOI1 but an entirely new item will be a footpath sweeper, exhibited for the first time in Britain. This appliance has already achieved wide acceptance abroad but technical details have not been made available up to the time of preparation of this review. Mounted on a Unimog four-wheel drive chassis with Mercedes-Benz engine, the Schmidt rotary snow cutter will again be shown.
The New Era street sweeper, which has been seen at the demonstration over the past two years, will on this occasion be exhibited by RGP Engineering Ltd.
Included in the exhibits of the Yorkshire Patent Steam Wagon Co. there is usually something to show the adaptability of this company's designs. Next week it is to show a 100gal gully emptier mounted on an electric chassis, this being intended for use in shopping precincts and in places such as multi-storey car parks. The company's display is to be completed by a Yorkshire sweeper on a short-wheelbase chassis, designed for operation on motorways and one-way-street systems. There is an independent engine drive to the suction fan, giving Constant suction at all speeds, and the Yorkshire piston compression and discharge system for the debris. The Yorkshire 1,200gal combined gully-cesspool emptier and the Yorkshire 1,000gal cesspool emptier will also be seen.
Edbro bulk refuse handling equipment will be displayed by Ford on a D800 120in. wheelbase chassis. Gross vehicle weight of this unit is rated at 12+ tons, with a bucket and payload capacity of 6+ tons. Apart from dealing with various types of general buckets within the payload weight, the handling equipment is also suitable for removing large items such as abandoned car bodies. The Powell DutTryn Dempster Dumpster will also be seen on a similar chassis. Lifting capacity here is 5 tons 19ci,vt, the Dumpsters providing for containers are from 4 cu.yd. to 15 cu.yd. capacity.
First appearance Making its first appearance at an IPC exhibition will be the Tennant 90 industrial sweeper which has a power unit that has been given special dust protection and it is claimed that this will last 15 times longer than ordinary heavy duty engines. The intention of this model is to cater for roundthe-clock use in areas where there is material too abrasive for ordinary sweepers. A 130 sq.ft. dust filter is employed. The Tennant 90 is stated to be capable of sweeping over 100,000 sq.ft. per hour. Another first-time showing by R. S. Stokvis and Sons Ltd., will be the Tennant TLR, a self-propelled unit that will permanently remove traffic lines in one operation at speeds up to 10ft per minute. It is designed to erase lines up to fin, in width in one pass without the use of chemicals, sand, or masking paint.
The Studebaker Clarke Debris-Vac, which has been supplied to about 100 municipalities as Well as a variety of other undertakings, will again be shown. An interesting feature is the use of low-pressure tyres to enable the machine to negotiate kerbs and similar obstructions without trouble.
In addition to other Tintern trailers, Allan Fuller Ltd. will be exhibiting a road-sign washer with 50gal tank, engine driven pump and extension brush.
Apart from the vehicles and appliances there will be many important items of equipment to be seen, among them the Danline BSM sweeper unit for fitting to tractors with pto. This machine now incorporates a slip clutch on the power shaft and splined transmission throughout. Danline brushes for use on road sweepers are available in steel wire, nylon and crimped polypropylene.
As usual Perkins will have a series of power units of appropriate capacities available for inspection.
