MAKERS of earth-moving and mechanical-handling equipment are showing many new and interesting machines in the hardware section of the British Industries 'Fair, which opened at Castle Bromwich on Monday last, and which closes on May 19. The exhibits, generally, are indicative of remarkable progress in development work over the past 12 months, and the influence of export requirements is much in evildence.

The new Goliath motor scraper and the recently announced BK-12 motor grader displayed by Blaw Knox, Ltd., Euston Road, London, N.W.1, , on Stand 1,303/1,202 outdoor, are of outstanding interest to users of heavy earth-moving equipment. The Goliath is a 12-ton cable-operated machine of open-top design, having a capacity of 15 cubic yds, and powered by a

150 b.h.p. oil engine, • The grader weighs 10 tons and is fitted with either a 94 b.h.p. oil engine or an 83 b.h.p. petrol engine. 'The gearbox has six forward speeds and two :speeds in reverse, and the controls are 'power operated.

A British-built 18-cubic-yd. scraper, based on Caterpillar specifications, is exhibited by the Birtley Co., Ltd., Birtley, Co. Durham, on Stand 1,302 outdoor. The parts of the British and American versions are interchangeable and maintenance is thereby facilitated, particularly in certain overseas countries. An important feature of the scraper is the provision for a second " pusher " tractor, which can be used when the machine is engaged on very heavy work. Three hydraulic angling bulldozers of Caterpillar design and British manufacture are also shown.

An 8-cubic-yd. scraper, specially designed to meet military requirements, is a notable addition to the range of earth-moving equipment manufactured by Onions and Sons (Levellers), Ltd., Moxley Road, Bilston„. Staffs (Stand 1,335/1,234 outdoor). The company's 20-cubic-yd scraper is now fitted with

B8 British-made 21.00 by 29 tyres at the back and 21.00 by 24 tyres at the front.

Ltd.. Grantharri, Lincs. Similar to all dumpers in the maker's range, the new vehicle features two-way steering and an equal

Boydell and Co., Ltd., Old Trafford, Manchester 16, on Stanch 1,013 and 1,200 outdoor. The standard I-cubic-yd. bucket may be replaced by one of 1-cubic-yd. capacity, or by a special full-width 1-cubic-yd. bucket. A crane attachment enables the machine to be used as a 1-ton mobile unit, and an easily fitted dozer can also be supplied. A buffer plate Is provided for the 3cubic-yd. 10B Muir-Hill dumper, which is fitted for moving rail trucks, the maximum shunting capacity being 100 tons on a straight and level track.

An attachment of considerable interest is shown by the Chaseside Engineering Co., Ltd., Station Works, Hertford, Herts., on Stand 1,305/1,204 outdoor. This supplementary equipment, which was evolved by the field-test unit of the Ministry of Works, is a brick-stacker for fitting to the Chaseside mechanical shovel. It can be fitted in about 10 minutes without disturbing existing parts. Capable of loading 100 bricks at a time to a height of 16 ft., the stacker may also be employed for carrying and loading timber, concrete lintels and so forth.

The latest shovel is the 1-cubic-yd. unit, originally designed for snow clearing and subsequently standardized as the successor to the i-cubic-yd. shovel for handling coal, coke and other comparatively light materials. An angledozer blade, a further recent addition, may be fitted to either the 1-cubic-yd. or the -cubic-yd. shovel. A bulldozer plate is available with the same fitting position.

The use of restrictor rings on its pneumatic tyres is .a feature of the Jones 4-ton mobile crai t. exhibited by K. and L. Steelfounders and Engineers, Ltd., Coburn Works, Letchworth, and, on Stands 1,334, 1,327 and 1.226 outdoor The restrictor rings give added stability

By dispensing with the reduction box in the HT2/8 four-wheeled industrial tractor, manufactured by Reliance Trucks, Ltd., Vale Works, Heckmondwike„. Yorks, and displayed on Stands D 257 and 154, it has been possible to reduce the overall height by about 8 ins. This modification is advantageous dimensionally, and it lowers the centre of gravity to provide (in conjunction with a sprung front axle) improved stability and adhesion on steep inclines and uneven ground.

The gear ratio of the worm drive has been increased to give the same overall reduction. It is also of interest-that the 50-cwt. heavy-duty Reliance truck has been reintroduced after two years.
