Door type electric gate hoists are used in all kinds of large-scale water supply and drainage, water conservancy and hydropower engineering. It is used to control the rise and fall of all kinds of large and medium-sized cast iron gate or steel gate or trash rack to achieve the purpose of opening and closing.
- Steel plate or box-type girder, electric driving motor of lifting mechanism, gear reducing hoist;
- The operating mechanism of the crane is driven by the motor, and the closed operating room is mounted on the frame;
- Running buffer device and windproof rail clamp are equipped with the gantry leg;
- The spreader moves up and down along the gate slot or around the hinge of the gate;
- The opening and closing of the gate in the movable water is related to the size of the load and the water hydrodynamic pressure;
- For large span gate, it needs double lifting points and keep synchronization;
- Large Lifting capacity, low speed, low work level, generally not more than 4 m / min, only for some quick gate, it can reach 10-14 m / min;
