Abstract

978,765. Jib cranes. J. TRANCHERO. Dec. 28, 1961 [Dec. 28, 1960], No. 46526/61. Headings B8B and B8H, [Also in Division E1] The collapsible jib 6, 7, 8, Fig. 1, of a crane which slews through 360 degrees is luffed by raising a pivot point 17 whilst the rear of the jib is pivoted by links 10, 11 to a sleeve 13 which slews but does not move vertically. Section 7 of the jib slides into section 8 and section 6 folds back about a hinge pin 9. The jib is raised by an hydraulic ram 14, 15 which simultaneously raises the load by a rope 20 fixed to a point 20a. Fig. 4 shows an embodiment in which the jib is mounted on a fork-lift truck and has an arm 23 pivoted about a point 6a by a ram 24. Guides 31 having a wheel 33 which runs up the post 14 are raised by the jib, and a rope 20 moves the platform 29 up and down the guides 31. With the jib rotated through 180 degrees and section 7 retracted a shovel 34, Fig. 5, mounted on the arm 23 may be operated by a ram 24 connected between holes a-f and a‹-f‹. As shown in Fig. 6 a platform 141 which can be tilted by a ram 143 is suspended from a link 148 pivoted to the jib at 110a. This link enables the platform to be lowered right on to the ground by means of a rope 120. The ram 114, 115 is itself pivoted to a trolley and can be tilted by a ram 140. In any of the embodiments described the ram which supports the jib may be replaced by either a rack-and-pinion or telescopic members operated by a rope and winch.
