Abstract

871,100. Mobile jet cranes. LIEBHERR, H. March 2, 1960 [March 12, 1959], No. 7333/60. Class 78 (4). The jib 11 of a mobile crane slides in a supporting-member 9 so that it can be retracted to the position shown and locked; the jib also slews through 360 degrees together with an operator's seat 8. In the form shown lateral guide-rails on the jib engage grooves in the member 9. Pins, which pass through holes 19, 20 in the member 9 and corresponding holes such as 17, 18 in the jib, lock the latter in extended or retracted position. A cable drum 25, operated by a hand-crank 26, slides the jib in the member 9 by winding in a cable 24 which may be attached to either end of the jib.
