Abstract
999,615. Mobile Jib crane; erecting poles; slings. TEL-E-LECT PRODUCTS Inc. Oct. 17 1962 [Oct. 30, 1961], No. 39340/62. Headings B8B and B8H. A mobile jib crane for use in erecting poles, comprises a boom 12, Fig. 1, having an extendible stinger 15 which carries a winch 56 at its outer end so that movements of the stinger 15 may be made without separate adjustment of the winch 56. Forwardly extending spaced brackets 57, 58, Fig. 3, are disposed on each side of the winch 56 to engage and locate the poles to be erected when held by the winch cable 60. A hook 62 is arranged for forming a loop round the pole and the cable is stiffened by a coil spring 63 which operates to straighten the cable for ready release from the pole when the cable is slackened. The mounting for a digger 19 on the boom is described in Specification 999,616.
