B.I.F. Exhibits Show Trend Towards the Production of Mobile Appliances to Fit Any Kind of Work
MATCHING the machine to the job, rather than organizing the job to facilitate working with available machines, is a trend which has increased the size range of all types of mobile equipment used for handling materials and finished products. This particularly applies to fork-lift trucks and dumpers, and the extremes in capacity shown at the British Industries Fair at Castle Bromwich exemplify how the demand for increasing specialization is being met. The Fair opened on April 27 and will close on May 8.
Shown by Shelvoke and Drewry, Ltd., Letchworth, Herts, on outdoor Stands 1341 and 1240, the recently introduced range of S.D. Freightliner heavy-duty fork trucks includes machines with capacities of 18,000 lb. with lifting rheights up to 20 ft. One of these has a crane jib attachment which can readily be fitted in place of the forks, and another is exhibited with a li-cu.-yd. hydraulically operated scoop. Orders for Freightliners have been received from 13 countries.
At the other end of the fork-truck range is a new machine of 1,000 lb. load capacity with pedal traction, shown by R. H. Corbett and Co., Ltd., Burgess Hill, Sussex, on outdoor Stand 1350. The machine is known as the Hydruped and can be propelled at .a walking pace with a pedal effort equivalent to that necessary for easy cycling. Lifting and steering are by means of battery energized electro hydraulic systems, the standard lifting height being 6 ft. The design of the truck gives lightness with a high degree of manoeuvrability.
Other new products displayed on the Corbett stand include the Bickerstaff fork attachment, designed for brick handling without pallets, and the 1-Iydrum High Stacker for loads up to 3 cwt. The stacker is specially suitable for use in narrow alleyways, and, when necessary, the operator may be raised with the load to stack the goods in shelves up to 12 ft.
One of the largest machines at the Fair is the Euclid 13-cu.-yd. bottomdump wagon, exhibited by John Blackwood Hodge and Co., Ltd., 11 Berkeley Street, London, W.I, on outdoor Stands 1305 and 1204. It is of tapered form to distribute the 40,000-lb. payload in the correct proportions.
The trailer is articulated to a Euclid four-wheeled tractor similar to that employed for towing the 12-16-cu.-yd. scraper, shown as a prototype unit at the 1952 Fair and this year in production form. The tractor is powered by a Leyland 154 b.h.p. oil engine or an A.E.C. oil engine developing 150 b.h.p. The maximum speed of both machines is 29 m.p.h.
Among the smallest dumpers displayed is one of the two new machines which supplement the standard range produced by Aveling-Barford, Ltd., Grantham, shown on outdoor Stands 1116 and 1217. It is a three-wheeler powered by a 4.5 b.h.p. single-cylindered petrol engine and has a capacity of cu. yd. The two large load-carrying rear wheels provide positive traction, and the machine is capable of 3.} m.p.h. in both forward and reverse gears. The turning radius is 6 ft. 2 in.
The other new Aveling-Barford product is a 3-cu.-yd. dumper with a simplified two-way steering system, designed for working with the smaller range of excavators. The gearbox provides four speeds forward and two in reverse, and the machine is capable of travelling at 13.1 m.p.h. and 5 m.p.h. in the respective top gears. Handand foot-operated brakes are fitted, the latter being of the Lockheed two-leading-shoe type.
Reverting to fork-lift trucks, interesting battery-electric vehicles of new design are shown by I.T.D., Ltd., 95-99 Ladbroke Grove. London, W.11, on outdoor Stand 1356, and by Wessex Industries (Poole), Ltd., West Street, Poole, Dorset, on outdoor Stands 1335 and 1234.
The I.T.D. exhibit is the Stacatruc 45EH/9 heavy-duty machine with a load capacity of 4,500 lb. at 20-in, centres and a lifting height of 9 ft. Four road wheels are employed to give the greatest possible stability with a steering axle fitted with semi-elliptic springs and mounted on an axially pivoted frame. The suspension system has the advantage that the displacement of the truck caused by vertical wheel movement is only half the wheel displacement, and the vehicle can negotiate severe surface irregularities without rolling.
The new Wrigley fork truck exhibited by Wessex Industries has a load rating of 1.000 lb. at 15-in, load centres and a lifting height of 7 ft. 6 in. The lifting speed is 25 ft. per min, and the travelling speed is up to 5 m.p.h. forward and 2 m.p.h. in reverse.
A Three-wheeled Dumper
Other Wrigley machines shown for the first time are a 10-cwt. dumper powered by a Villiers 125 c.c. four-stroke petrol engine and a battery-electric industrial truck with a load capacity of 15 cwt. The dumper is a three-wheeler with a single-wheel steering head in unit with the engine which can turn through 360°. The three-speed gearbox provides, therefore, an equal number of ratios forward and in reverse.
Following the great demand for the Model FTF flame-proofed fork truck, displayed for the first time at last year's Fair, Coventry Climax Engines, Ltd., Widdrington Road, Coventry, developed flame-proofing equipment for the Model TMD209 (shown on outdoor Stand 1344).
The main exhibit shown by Conveyancer Fork Trucks, Ltd., Liverpool Road, Warrington, Lanes, on Stands D717 and 616, is the Model E2-20 battery-electric three-wheeler, with a capacity of 2,000 lb. at 20-in, load centres, which is particularly well suited for loading rail vans and road vehicles.
Included in the range of equipment shown by Ransomes, Sims and Jefferies, Ltd., Orwell Works, Ipswich, on outdoor Stands 1317 and 1216, are battery-electric fork-lift trucks of i-ton to 2-ton capacity, and industrial trucks of 1-ton to 4-ton capacity with fixed or elevating platforms. Tipping trucks, tiering trucks and electric tractors are also displayed The Petter single-cylindered air-cooled oil engine developing 5 b.h.p, has been fitted to a number of lightweight machines formerly powered by petrol c30
engines, a notable example of its use by a Fair exhibitor being the Benford 4-ton dumper, which has four wheels and a hopper capacity of 12 Cu. ft. The machine is shown on outdoor Stands 1211 and 1110 by Benford, Ltd., The Cape, Warwick.
Another small dumper fittett w'th the Petter oil engine is an Il-cu.-ft. machine displayed by Thwaites Agricultural Engineering Co., Ltd., Cubbington, Leamington Spa, on outdoor Stand 1346. George Fowell, Ltd., Rabone Lane, Smethwick, 40, Staffs. (Stand A230), announce that the G.F. f-cu.-yd. dumper is available with this engine.
A 3-cu.-yd. side-tipping trailer dumper of the four-wheeled swan-neck type is an interesting exhibit of Whitlock Bros., Ltd., Great Yeldham, Essex, on outdoor Stands 1345 and 1244, an important feature of the vehicle being overrun brakes. A similar braking system is fitted to a cable-drum carrier for loads up to 5 tons and drums up to 6 ft., which is shown on the same stand. The carrier has pneumatic tyres and is supplied with rubber-jointed tracks for use over bogs and swamps.
The production of open-bowl scrapers is a development of importance to users of earth-moving equipment, and the display of a new Onions 14-cu.-yd. machine of this type as part of the matched equipment for the Vickers VR.180 tractor is opportune. Shown by Jack Olding and Co., Ltd., Hatfield, Herts, on outdoor Stands 1347 and 1246, the scraper incorporates a central-thrust cable-operated tailgate, which allows the operator a clear view of the earth entering the bowl. Flush-sided construction is employed to facilitate scraping close to a bank.
Representative examples of the concern's wide range of earth-moving equipment are shown by Blaw Knox, Ltd., 90-94 Brompton Road, London, S.W.3, on outdoor Stands 1303 and 1202, much of the equipment being based on David Brown Trackmaster and Fowler Challenger crawler tractors. The BKI2 grader, which is selling in large quantities abroad, is also exhibited.
Included in the numerous hydraulically operated shovel and scoop attach
ments displayed by F. E. Weatherill, Ltd., Union Road, London, N.17, on outdoor Stands 1109 and 1008, is the prototype of a -1-cu.-yd. loader fitted to a Fordson Major oil-engined tractor. The bucket is moved to the back of the tractor on its supporting arms for loading and to the front for unloading into a road vehicle or for dumping. Other new Weatherill attachments, also mounted on Fordson Major tractors, comprise a 2-cu.-yd. coke loader and a i-cu.-yd. high-lift loader, both of which have tipping buckets.
A Shunting Tractor
A Mercury tractor for shunting railway wagons and so on, known as the Shuntug, is displayed by Railway Mine and Plantation Equipment, Ltd., Imperial House, Dominion Street, London, E.C.2, on outdoor Stand 1352, the machine being powered by a Perkins P4 engine, which gives a drawbar pull of 4,800 lb.
A mobile elevator-conveyor, based on a Ferguson tractor, is a feature of outdoor Stands 1321 and 1220, on which is shown a number of the portable conveyors and elevators produced by T. and T. Works, Ltd., Billesdon, Leicester. The buckets feed a short conveyor which overhangs the tractor.
