1.1
EVILLE Industries (Mansfield) Ltd., Mansfield, Notts., has announced that its Dumptrailer articulated single-axle tipping trailer (COMMERCIAL MOTOR, December 16) is available in a standard range of six models with capacities up to 25 cu. yd.
The models are known as the DTS 12, DTS 15, DTS 18, DTL 15, DTL 20 and DTL 25, the figures indicating Cu. yd. capacities in each case. Nominal payload in all cases is 16 tons, while the maximum angle of tip is 55 degrees.
A trailer wheelbase of 13 ft. 9 in. is common to the first three models, while the wheelbase of the three heavier models is 17 ft. 9 in. Maximum body height varies from 4 ft. 11 in. to 6 ft. 11 in. and ground to body floor height from 4 ft. 3 in. to 4 ft. 11 in. The centre of gravity of a loaded body is 4 ft. above the ground.
A three-line air-pressure-operated braking system is fitted incorporating a Clayton Dewandre load-sensing device. Provision is made for a separate braking system operated from the cab.
It is claimed that the geometry of the tipping mechanism improves traction when the vehicle is reversing.
At a demonstration in Mansfield on Wednesday a 13 cu. yd. Dumptrailer (in effect, a tailboard equipped version of the 12) designed for use with any 24-ton-g.t.w. tractive unit was shown tipping ballast loads up to about 16 tons—in this case hauled by a Bedford KM.
Controlling the movement of the motive unit or the semi-trailer enables a compact heap to be tipped. The maker claims the Dumptrailer will not tip over sideways until the outfit is tilted to more than 20 degrees. This Dumptrailer costs £1,474 plus £34 for tailboard (optional).
A second Dumptrailer, of 15 cu. yd. capacity. was demonstrated loaded with coal slack, while a film showed the excellent traction properties of the outfit on an opencast coal site.
