A remotely operable lid for storage bins to be used in conjunction with a storage bin (10) having an access opening (11). A cover plate (18) is carried within a pair of guides (20, 22) such that the plate may be slid laterally in the guides. The guides (20, 22) are held spaced apart by end members (26, 28) which in conjunction with the guides, form a frame. Affixed to the bottom of the frame is a cylindrical band (46) which is sized to accept within a ridge (48) extending upward and around the access opening perimeter of the storage bin. The lid and frame are thus fixed atop the access opening of the bin. Attached to the lid are two eyelets (30, 32) and attached to the frame is a pulley (30). Ropes are attached to the eyelets, one of which is threaded through the pulley. The ropes are extended downward along the side of the bin to ground level. An operator at ground level can then pull one of the ropes to cause the lid to slide over the access opening, and pull the other rope to cause the lid to slide away from the access opening, thereby permitting entry of materials into the bin. The flange extending from the access opening is notched (64, 66, 68) to assure a complete closure of the access opening by the lid.
