Abstract
A floating grab installation for recovery of sand and gravel is disclosed. The installation includes a catamaran-type float or pontoon having a gripper and gripper support thereon. The gripper transfers the sand and gravel to an underwater tank having an endless bucket dredge which plunges to its lowest point. Floating grab installation for the recovery of sand and gravel including a float body having means supporting a gripper, characterized in that to the float body (1) there is attached an underwater tank (7) having an internal predetermined water line, and into which at a lowest point of said tank there plunges an obliquely upward-conducted bucket dredge (9) characterized in that the underwater tank (7) is constructed as an upcurrent container which is provided with spray nozzles (16). Between the gripper (4) and the underwater tank (7) there is arranged a tipping or scraping grate (5). The underwater tank (7) is connected by means of a funnel (6) to the tipping or scraping grate (50, the side walls (10, 11) of which are directed as a chute against the tank bottom. On an upper edge of the tank (7) there is arranged at the water line a surrounding overflow gutter (18), to which an outlet gutter (18') is connected.
