Dam floodgate gantry crane can be divided into one-way cranes and two-way cranes. The one-way hoist is fixed on the gantry. The gantry runs along the tracks on the dam. And its service area is a line, which can only be used to lift a gate in the same row, while the two-way gantry crane uses a trolley to run perpendicular to the crane. Therefore, the two-way gantry crane can hoist different rows of gates or trash racks upstream and downstream.

Dam floodgate gantry crane

1Steel plate or box-type girders, electric motor for hoisting mechanism, gear reduction hoist.
2The operating mechanism of the crane is driven by a motor, and the closed operating room is installed on the frame.
3A running buffer device and a windproof rail clamp are installed under the gantry outriggers.
4The spreader moves up and down along the gate or around the gate hinge.
5The opening and closing of the movable water gate is related to the size of the load and the dynamic water pressure of the water.
6For large span gates, double lifting points are required and kept in sync.
7Large lifting capacity, low speed and low working level, generally no more than 4m/min, only for some fast gates, up to 10-14m/min.

Dam floodgate gantry crane is mainly used for hydraulic equipment transport, installation and maintenance of hydroelectric generating units such as floodgates, trash rack etc.
