Abstract: A gantry crane for a container includes a portal main frame, a traveling mechanism, a translation mechanism, a hoisting mechanism and a spreader assembly. The spreader assembly includes a spreader body, two telescopic girders and a drive assembly. The drive assembly includes a cam, a sliding way and two sliding blocks. Two arc-shaped first sliding grooves are circumferentially provided on the cam. A middle of the sliding way is rotatably connected with the cam. Two sides of connection of the sliding way and the cam on the sliding way are provided with a second sliding groove. Each sliding block matches with the first and second sliding grooves, and can slide back and forth along them. The telescopic beams are slidably connected to the spreader body, and are symmetrically provided and connected to the sliding blocks, respectively.

Abstract: A discharging device for a vinasse tank, including a flipping component and a lifting component. The flipping component includes convex rods externally connected with opposite side surfaces of the tank, and a frame matched with the tank; the frame includes an outer frame and an inner frame; opposite inner supporting rods of the inner frame are provided with C-shaped grooves having openings downward and matched with the convex rods; respective C-shaped grooves include a through hole penetrating through lower parts of groove walls on both sides; a gear lever matched with the through hole and a first driving mechanism for driving the gear lever to move left and right axially along the through hole are arranged in the inner supporting rod; and a second driving mechanism for driving the inner frame to flip is arranged at a joint between the inner supporting rod and an outer supporting rod.
