Abstract

1,067,603. Mobile Jib-cranes. H. REID. Feb. 14, 1966 [Feb. 13, 1965], No. 6324/65. Heading B8B. In a mobile jib-crane which has a pivoted A-frame 5 for luffing the jib 3, intermediate jib-sections 21, stacked for transport on brackets 22, are unloaded by means of slings 24 supported from a bar 8 extending laterally of the A-frame. The jib is lowered to position 3C and simultaneously the A-frame moves through position 5A to position 5B. This causes the jib-sections 21 to be raised from the brackets 22 by the A-frame which is then lowered until the sections rest on the ground. If the turning moment provided by the jib on the A-frame is insufficient to raise the jib section either a load may be supported by the jib to increase the moment or the load hook may be attached to the vehicle chassis and tensioned as at 18A. The luffing frame may be other than A-shaped, e.g. rectangular, trapezoidal or a simple post.
