Abstract

1535412 Telescopic assemblies KERNFORSCHUNGSZENTRUM KARLSRUHE GmbH 7 April 1976 [31 May 1975] 14087/76 Heading B8H A telescopic assembly, for manipulating heavy loads, such as drums carrying radioactive material, wherein the assembly is subject to bending stresses, comprises three telescopic sections 1, 2, 3 of rectangular section. Sections 2, 3 have respective sets of guides 35-38, 62-65 on their exterior surfaces, while sections 1, 2 have respective sets of rollers 58-61, 27-30 in two planes, respectively, extending transversely to the longitudinal axis 6 of the assembly and co-operating with the guides such as, in use, to transmit the principal bending stresses in one direction, indicated by the double-headed arrow 8. The sections 1, 2 have friction brake linings, carried by respective sets of brake cylinders 43-46, 54-57 on their respective inner surfaces, which act at right angles to their respective rollers and on their associated guides. As shown, the assembly is mounted, with the axis 6 vertical, on a rotary coupling 5. Section 3 has a flange 7 into which a gripping device (not shown) may be attached and which lifts off-centre loads thus giving rise to bending stresses.
