Abstract

541,136. Jib cranes. BAXTER, J. Sept. 18, 1940, No. 14325. [Class 78 (iii)] A mobile crane, particularly intended for lifting engines out of vehicles, is provided with a cantilever jib 9 having a lifting hook 15 at one end and a connection at the other to a manually operated jack. The jib is pivoted to the upper end of a column 4 which is carried by a wheeled base and supports a hydraulic or other jack 18 connected to the jib through a lever 12 and a turnbuckle 16. The jack is supported by a chain 20 having vertically adjustable pivots.
