Abstract

1,061,753. Jib cranes. CRANE PRODUCTS MANUFACTURING CO. Inc. May 17, 1963, No. 19636/63. Heading B8B. [Also in Division G1] A mobile crane is provided with detector wires along the jib in which signals are induced on the approach to overhead power lines to give visible and audible alarm warnings in the operater's cab. In Fig. 1 (not shown) a detector wire runs from a reel along the main boom, and the jib; a second wire runs along the main and jib gantreys, and a third detector wire is connected between the hook and a reel on the jib. A switch 281 in the detector circuit, Fig. 2 (not shown), may be arranged to operate the alarm if the jib is raised too high.
