Abstract

988,308. Mobile jib cranes. HYDRAULISKA INDUSTRI A.B. Jan. 15, 1964, No. 1725/64. Heading B8H. The outer portion 8 of a jib 5 is pivotally connected to the inner portion 6 by a pin 7 and is adapted to be folded under the inner portion on extension of hydraulic rams 18, 20 and 19, 22 which are pivoted between a bellcrank lever 13, rotatably mounted on the pin 7, and the inner and outer jib portions respectively. The jib is pivoted at 4 to a head 3 rotatably mounted about a vertical axis on a pillar 7 on a lorry and is provided at its outer end with a load-engaging device (not shown). Specification 935,985 is referred to.
