motor device for training a mask of slope water system for inland navigation

摘要

The driving unit for displacing a retention barrier in the channel of a water-slope system comprises two flat longitudinal members each mounted on a row of carrying wheels supported on a runway formed by the top face of each channel side-wall. The longitudinal members are coupled together by cross-members mounted on top of these latter so as to form a highly rigid structure which is connected to the retention barrier by means of a pivotally coupled push-bar frame.
