By A. J. P. WILDING 0 N Tuesday the second International Construction Equipment Exhibition opens at Crystal Palace, London. It will certainly provide the most comprehensive display of equipment used on construction, building and quarrying that has ever been assembled in the United Kingdom Additional importance is lent to this year's exhibition by its selection as the "Nominated Exhibition for 1963" by the Committee for European Construction Equipment. Probably for this reason there will be an increase of some 30 per cent in the number of exhibitors compared with 1961, when the show was first held. There should be over 200, the largest number ever assembled at an exhibition of its type in this country.
Major interest from a commercialvehicle aspect will be exhibits in three main categories—vehicle-mounted concrete mixers, crane carriers and dump trucks—and it is principally with these types of unit that this review will deal.
Fodens Ltd. (Stand A.98) will be the only British vehicle maker exhibiting chassis at Crystal Palace. Three truck mixers, two dump trucks and a cranecarrier chassis are to be on display. Stothert and Pitt mixers will be mounted on two chassis, a 6-cu.-yd. model on a six-wheeler and a 9-cu.-yd. unit on an eight-wheeler. The third truck mixer will be another six-wheeler with a Rapier 6-cu.-yd. unit. One of the dump trucks will be a four-wheeler with a capacity of 8 Cu. yd. and the other will be a sixwheeler with an 11-cu.-yd. body.
The crane carrier to be exhibited is a recent introduction by Fodens, being the Low-line model which was illustrated in The Commercial Motor, May 3L A
B40
feature of this model is the very low cab mounted forward of the front bogie and the engine. The chassis will be exhibited without a crane mounted on it.
A Low-line with a crane will however be featured by Thomas Smith and Sons (Rodley) Ltd. (Stand A.38). This will have a Smith T.30 crane which is of 30-ton capacity. Basic boom length is 30 ft. and the boom in the travelling condition is positioned over the driver's cab, a top section being arranged to fold sideways to reduce overhang at the front of the vehicle. Extension pieces are available to make the maximum length of boom 130 ft.
Foden chassis will be seen on a number of other stands at the exhibition. NCK-Rapier Ltd. (Stand A.72) will be showing a six-wheeler mounted with a Rapier 6-cu.-yd. mixer. This will be on show for the first time and employs twinhydraulic pumps in tandem direct-coupled to a Ford diesel engine to provide three
drum-speed ranges in either direction of rotation. Mixed batch capacity is 6 cu. yd. and the model has an agitating capacity of 7.5 Cu. yd. A new Rapier crane, the Cheviot, will also be shown by the concern and this will be mounted on an Atkinson six-wheeled chassis. The Cheviot has a maximum lifting capacity of 20,000 lb. at 8-ft. 6-in, radius with a 20-ft. jib. The crane will be shown with a 70-ft. strut jib.
Truck mixers will also be shown by three other manufacturers, Eonit Engineering Co. Ltd. (Stand No. B.40), Ritemixer Ltd. (Stand No. A.68) and Winget Ltd. (Stand No. D.48). Eonit is to feature its 4-cu. yd. agitator mounted on a Thames Trader chassis. This model employs full hydraulic drive to the drum and the drum is also tilted hydraulically. Two models will be displayed by Ritemixer; one on a Guy Warrior six-wheeler, the other on a Foden eight-wheeler. The mixer on the Guy will be a 5/6-cu. yd. mixer/agitator, which will be shown for the first time. Based on the design of the Dutch Mulder mixer it is powered by an independent B.M.C. 2-2-litre diesel engine, the drive to the drum being mechanical. A 7-cu. yd. mixer will be mounted on the Foden. An A.E.C. Marshall six-wheeler will form the basis for the Challenge 6-cu. yd. mixer to be shown by Winget. As with other models
made by the concern, separate engine hydraulic drive is used and the hydraulic system has high and low pressure circuits so that large quantities of hydraulic oil are not used.
The largest lorry-mounted crane at Crystal Palace will be the Centurion, which has been recently introduced by Steels Engineering Products Ltd., and will be displayed on the stand of Steel and Co. Ltd. (D.78). It is claimed to be the largest-capacity lorry-mounted crane in the world. The crane has a capacity of 75 long tons (100 short tons) with a 50-ft. jib at 12-ft. radius or 3 long tons with a 200-ft. jib at 100-ft. radius. The crane is mounted on a specially designed Coles eight-wheeled crane carrier which is powered by a Rolls-Royce 250 b.h.p. turbocharged diesel engine. The power unit used for crane duties is an A.E.C. 11.3-litre diesel direct coupled to a specially designed generator. Steel and Co. Ltd. is also to show a range of mechanical handling plant, including mobile cranes, the newest of which is the Victor.
Lambert Engineering Co. (Glasgow) Ltd. (Stand A.4) intends to show three of its lorry-mounfed cranes. The Hydrocon Hamilton is the latest addition to the range, having a capacity of 9 tons at 10 ft. radius and jib lengths of up to 85 ft are obtainable. A four-tvheeled chassis is used for the Hamilton, a Leyland engine being employed as the power unit. The basic jib is 25 ft. long and four 15-ft. intermediate extensions give the total jib length. The Highlander Super is another new machine which is to be shown. This has a eapacity of 6 tons at 10 ft. radius on a 24-ft. jib and four 10-ft. intermediate jib extensions give a maximum length of 64 ft. As with the Hamilton the extensions can be carried on the platform: this can be a 4 x 4 or 4 x 2 chassis (also in common w;th the Hamilton) and a Leyland or Perkins engine can be incorporated. The third model of Hydrocon crane which will be shown is the Hebridean which will be mounted on a special Foden six-wheeled chassis. This crane has a capacity of 15 tons at 10 ft. radius on a 25-ft. jib or 2.5 tons at 30 ft. radius on the maximum 100-ft. jib.
For Sale and Hire
A wide range of equipment for sale and hire will be featured by George Cohen Sons and Co. Ltd. (Stand 0.70). Pictorial displays will be used to cover the P. and H. Harnischfeger equipment which includes lorry-mounted cranes. The concern will also be featuring two Jones mobile cranes, both of which are to make their exhibition debut at Crystal Palace one of them being the lorrymounted KL 15-25. The Hiab lorry loader, model 172, which now has a capacity of 46 cwt., will also be featured. This will be shown mounted on a Commer tractive unit.
Redler Conveyors Ltd. is another concern featuring a lorry-mounted crane. This will be the Redler 6-ton unit and will be mounted on a specially designed Seddon four-wheeler with heavy-duty axles, the real axle being unsprung. The crane can be fitted with jib lengths up to 64 ft. or will take a 56-ft. jib with a 15-ft. fly jib. The standard jib length is 24 ft. and the spare jib sections can be carried on the superstructure. Power for the crane movements is provided by a Perkins or Leyland engine driving a
Vickers-Detroit vane-type hydraulic pump.
On show for the first time at the exhibition will be the new Iron Fairy Garnet mobile crane to be shown by the British Hoist and Crane Co. Ltd. (Stand A.50). This has a capacity of four tons with duodirectional all-round slewing. A Ford diesel engine provides power for vehicle propulsion and hydraulic operation of the telescopic jib and lifting motions. The Garnet has a road speed of 30 m.p.h.
Greenham (Plant Hire) Ltd. (Stand D.66) is taking part in the exhibition to feature its hiring facilities. Cranes from five to 50 tons are available and two lorry-mounted units will be included in the concern's display. These will be a Hydrocon Highlander 6-tonner and a model from John Allen and Sons (Oxford) Ltd.—the K 64—which has a capacity of six tons. The latter concern will also be exhibiting its lorry-mounted cranes on Stand 36.
Dump Trucks Two dump trucks will be featured by Aveling-Barford Ltd. (Stand A.78). These will be the SN 35-ton model, which is powered by a Rolls-Royce 450 b.h.p. turbocharged diesel engine, and the SR 10-ton model, which is to be shown with a number of recent changes incorporated. The main one is re-shaping of the light-alloy body on which the conventional scow end has been superseded by a body with a continuous upward 1342 sloping bottom plate. The automatic
tailgate feature offered by the concern is still available as an extra. Capacities are altered slightly with the changes; without tailgate, heaped capacity is 9-5 cu, yd. arid with tailgate 10.5 cu. yd. Maximum tipping angle is 53' and payload is also increased as the light alloy body weighs about one ton less than the standard body.
Scammell dump trucks are to be exhibited again by the maker's U.K. concessionnaire, R. Cripps and Co. Ltd. (Stand A.16). On display will be the Sherpa 4 x 2 machine, the Mountaineer 4 x 4 with its new Telehoist fullpower-return twin-ram tipping gear and redesigned 8(10-cu. yd. body and the Himalayan 30.5-ton model. Also to be shown are two exhibits of full-size cutaway transmission units as used on Scarrirnell dump trucks.
Once again the A.E.C. 20-cu. yd. Dumptruk, which has a 55-ton g.v.w., will be exhibited by Scottish Land Development Ltd. (Stand D.54), A.E.C.'s U.K. concessionnaire for the sale of dump trucks. Another concessionnaire exhibiting dump trucks will be Thos. W. Ward Ltd. (Stand A.36), which is to include in its exhibits the Automaster 15-ton model made by Douglas Equipment Ltd. This model has a body struck capacity of 12 cu. yd, and is a six-wheeler with automatic transmission, powerassisted steering and a maximum tipping angle of 70'. Demonstrations will be given by T. T. Boughton and Sons Ltd. on the proving ground at Crystal Palace—site P.G.2I4— of the Marrel multi-bucket material handling unit which, for the exhibition, will be mounted on a Bedford KGT chassis. Boughton has recently begun manufacturing this Marrel equipment for the U.K. concessionnaire, Aero Maintenance Equipment Ltd., Bruton Street, London, W.1, and the unit on show differs from previous models imported into this country. The main alteration is the fitting of patented roller compensating jacks at the rear of the lifting frame which will allow laden buckets to be removed from confined areas without them having to be hoisted onto the deck of the vehicle. When the vehicle has been driven to a clear space, final positioning can be carried out. Also to be exhibited by Boughton are vehicle winches and recovery winches.
Loaded in Three Minutes • Loading heavy equipment in a short time is a feature of an 8-ton low-loading trailer which will be shown for the first time at the exhibition by Rubery, Owen Ltd. (Stand C.24). It is claimed that the trailer can be loaded in three minutes and another loading aid also to be shown for the first time by the concern will be Tirfor 30-cwt. winch attachment which will be fitted to the front of the trailer. The trailer is designed for carrying earth
moving equipment and the winch is fitted so that static machinery can be loaded more easily. When loading the trailer, the equipment moves up a fixed ramp and on to the trailer platform until the platform starts to tip. As the equipment is driven slowly forward the platform goes fully down to the horizontal and is locked in this position.
For Air Supply
Two versions of the Powertruc will be featured by The Powertruc Co. Ltd. (Stand B73). The Powertruc is a mobile power unit, being a Thames 15-cwt. chassis/cab carrying a Ford 592E diesel engine which is used to power the vehicle as well as drive equipment such as a compressor or generator also mounted on the chassis. One of the Powertrucs shown will be equipped with a Hydrovane compressor, the other will have a Bristol Duplex compressor.
Bristol Pneumatic Tools Ltd. will be showing mobile, two-wheeled compressors on its own stand—No. A120—and equipment of the same type will be featured by The Hymatic Engineering Co. Ltd. (Stand B82) and Broom and Wade Ltd. (Stand D7). Broom and Wade will also show pneumatic tools.
Exhibitors of engines designed for industrial and equipment applications will include British Deutz Ltd. (Stand Al 12), Perkins Engines Ltd. (Stand B10) and the Leyland Motor Corporation Ltd. (Stand A14). The Leyland group exhibits will include Leyland and A.E.C. engines as well as Self-Changing Gears and Albion gearboxes.
