Abstract
1,178,520. Crane safety device. J. D. BROWN, R. N. MOSEMAN, H. L. MATTERN, J. K. SHIRIN, D. L. ROSS, G. W. ZIMMERMAN, and G. D. McGEHEE. 2 Oct., 1968 [2 Oct., 1967], No. 46865/68. Heading B8B. A boom travel limiting device for a mobile crane 12 with a frame 15 supported by forward and rearward wheels 16, 17 for transport, and additionally by removable legs 18 when in use, comprises stop blocks 55 adjustably mounted on a stop mounting track 40 on the frame 15 and a bumper assembly 70 attached to cab 20 carried on a circular bearing 22. Normally open limit switches 105 on the bumper assembly 70 give an audio signal as the assembly approaches either of the stop blocks 55 and return the operator's control lever 26 to a neutral position.
