Abstract

1,173,523. Self - erecting tower cranes. RICHIER. 24 Feb., 1967 [24 Feb., 1966], No. 9077/67. Heading B8B. The telescopic tower 4, 5 of a crane erects itself about a pivot 6 as the tower is extended from the retracted position shown in Fig. 1 by a tie rod 8 pivoted to the base 2 at 9 and to the upper part 4 of the telescopic tower at 7. The tower may be extended by a ram which acts between the two sections, Fig. 4 (not shown), or by rack and pinion means, Fig. 5 (not shown). Alternatively the tower may be erected by a cable 23 and winch 22 during which movement the strut 8 will extend the tower from the retracted position. The separate struts 8 may be replaced by a single lattice frame.
