I. A Shape Double Girder Gantry Crane Introduction:
1. This gantry crane is widely used together with winch or trolley for lifting device.
2. It is a medium and heavy size crane which travels in track.
3. Structure: main beam, support legs, crane traveling organ, trolley, electric equipment, strong lifting winch
4. Power is supplied by cable or slide wire.
5. It is prohibited for lifting melt metal, flammable, explosive, corrosion, overloading, dust and other dangerous operations.
II. A Shape Double Girder Gantry Crane Application:
workshop, storage, port and hydroelectric power station and some other outdoor place, where it has a high frequency or more lifting times.
III. A Shape Double Girder Gantry Crane Environmental Conditions:
1.The temperature in the working environment should be in the scope of -20DC to 45 DC and the relative humidity is not higher than 95%(with dew).
2.During work, the wind speed should be no higher than 20m/s; and during non-work, the wind speed should be no higher than 44m/s.
3.The crane travelling lane is supposed not to slope more than 1% and no more than 3% for local slope. The ground slope on the two sides of the span should be in the same direction, that is to say, both upslope or downslope at the same time.
