Slide unit and swivel head for fixing the samples (all models) The output shaft flange is fitted with a square shaped pattern of threaded bore holes. Here, any kind of fixtures can be mounted. A slide unit is standard outfit. It is mounted to the output shaft flange by means of 2 clamp bars. Here, too, any kind of fixtures can be mounted, now with possibility for coarse and fine adjustment of the hight. For any kind of plugs or couplers, a swivel head is standard outfit. Fitted with bushings and fitting plates, 2 adapters with diameter 48 mm can be fixed. The swivel head allows to turn the samples by 90°very quickly. 1 Slide unit, with spindle for fine adjustment of the height, lead 1 mm, with 2 clamp bars for coarse height adjustment, can be mounted at a turn of 90° too 1 Swivel head, mounted on the support of the slide unit with swivel main plate, with 2 bushings, inner diameter 48 mm, for carrying the adapters F 39.7X and with 2 fitting plates for right angle plugs, dismountable, with bores, inner diameter 48 mm, too. 2 arresting pins, for arresting the bushings at two positions, which are turned by 90° Guidance for the samples and Loading weights (all models) 1 Metal plate, with elongated holes of 15mm x 45mm as guides, with 4 Distance rods, which support the metal plate at a distance of 250 mm underneath the swivelling axis. As there are some standards, which prescribe guides 300 mm underneath the swivelling axis, the metallic distance rods, which are 50 mm long, can be dismount. 2 Frames according to further preｓｃｒｉｐｔions; detachable for the case, that they are not needed 2 Sets of weights for sample loads from 5 N to 60 N, that means from approx. 0,5 kg to approx. 6,0 kg, with each 1 weight carrier 5 N with clamping kit, 1 weight piece 5 N, 1 weight piece 10 N and 2 weight pieces 20 N. The bottoms of the weight carrier and of the weights are fitted with a threaded bore hole. The weights are fitted additionally with appropriate thread bolts on the top. By that way, weights can be easily added or re-moved. Design : Floor type housing, of sheet steel, papyrus-white structure varnished, swivel head mainly of anodized aluminum, weights and parts of the swivel-ling gear browned, small parts browned or nickel plated, for connection to A.C. 230 V 50 Hz.
