ADDING only 36 lb. to body weight. compared with I+ cwt. for a steel lining, a plastics covering for the timber floors of tipping vehicles is being offered by Tom Byatt (Engineers), Ltd., Fenton, Stoke-on-Trent.
The floor is scored for a key, and a layer of Bakelite polyester resin containing abrasive grit is spread over the surface. A 2-oz. glass-fibre mat impregnated with a similar mix is then placed on the first coat, and finally a resin containing a high proportion of the grit is added.
The covering is then rolled and allowed to set. Any loads except those likely to burn it, such as hot ashes, can be accommodated, and the treatment is particularly valuable for wet loads.
Proving tests have included shock loads of 2-cwt. granite blocks dropped from a height of 3 ft. Under service
conditions, 10-12 short hauls a. day with loads of .granite and rock ore have not. it is stated, resulted in Undue wear.
The surface has been approved by the Board of Trade for incorporation in calibrated bodies.
