Abstract

1,135,465. Telescopic tower cranes. RICHIER SOC. ANON. 20 May, 1966 [21 May, 1965], No. 22650/66. Heading B8B. A tower crane has a telescopic tower with an upper part 14 which reciprocates within a lower part 13 in which the upper part has an upper portion 8 of smaller cross section than a lower portion 9. The latter mates with the lower part in such a way that the upper part is supported throughout its range of movement. The two parts of the tower may be either square or triangular in cross-section. Figs. 7 and 8 (not shown), illustrate diagrammatically two constructions of the upper part of the tower.
