Abstract
This article introduces the history and development of log grapple in China. According to the special conditions of Chinese forest areas, we have selected log grapple driven by electric drum, and have analyzed and calculated its parameters theoretically. This is the first log grapple driven by an electric drum made successfully in China. The Model DZ1 log grapple has a large closing force, works safely and is suitable for the special forest working conditions in China.
