Abstract

1,018,695. Mobile jib cranes. DE CAIR M.A. July 14, 1964 [July 22, 1963], No. 29028/64. Heading B8B. A mobile crane comprises a mast 13, Fig. 1, and a/jib 14 both pivotally mounted on a cab 11 for angular movement in the vertical plane by topping lifts 17, 19 respectively. A counterweight 23 may be provided. The jib 14 may be pivoted to the mast 13, Fig. 3, at 28. The lower pulley block 36 of the topping lift 17 is supported on collapsible gantry arms 32, 35 which are held in the position shown by cables 34. Fig. 2 shows the mast 13 supported in a vertical position by guys 74 and a spider 72. Either the mast or the jib may be used on its own as an ordinary jib crane (see Figs. 6, 7, not shown). A mast stop is provided, Fig. 3, comprising arms 42, 44 which are pivoted to each other at 45 and to the jib and mast at 43, 46 respectively. When either the jib or mast or both approach a critical inclination a wheel 47 abuts an inclined member 48 to prevent further angular movement. The mast is preferably longer than the jib.
