Abstract

879,098. Load handling machines LUDOWICI, J. W. Oct. 10, 1957, No. 31757/57. Class 78 (3). [Also in Group X] A lifting device comprises a pair of articulated structures 1, 2 extendable by fluid pressure jacks 3, and interconnected by transversely extending members. As shown in Fig. 3 the pairs of linkages 1, 2 are interconnected by working platforms 8, 15. In a modification of this arrangement (Fig. 1, not shown) the links fold inwardly. Fig. 6 shows an embodiment in which a pair of linkages 1, 2, 3 are interconnected by a lazy tong linkage 17. The links 1 are constructed as shown in Fig. 8.
