ABSTRACT:
A lift-fork type carriage means capable of lifting, carrying and emplacing filled gabion baskets into position in a revetment mattress lining a stream bed or other erosion prone area to control water erosion. The gabion basket handling device is characterized by a plurality of lift-fork tines adapted to engage the under-surface of a filled gabion basket, a plurality of hold-down arms rotatable into contact with the top and one side of the filled gabion basket by linkage means actuated upon application of lifting forces to the apparatus. The hold-down arm linkage is counterbalanced so that lifting forces applied to the apparatus when empty are insufficient to rotate the hold-down arms into a closed position.
