Normally there will be two lifting trolleys on the gantry cranes or double gantry cranes share the same track and work together when lifting building materials. The lifting weight is generally 100 to 1,500 tons; the span is 185 meters; the lifting speed is 2 to 15 meters/minute, and the inching speed is 0.1 to 0.5 meters/minute.


Features

1.This type building gantry  crane is applicable to bridge construction, highway constructions,  inland wharfs, container yards, railway freight stations, coastal freight yards or frontier wharfs.

2.Normally there will be two lifting trolleys on the gantry cranes or double gantry cranes share the same track and work together when lifting building materials.

3.If lifting containers, the gantry crane will be equiped with rotating spreaders for handling container smartly.

3.Can be equipped with our company's independent research and development of flexible two-way anti-swing technology.

4.The three-in-one speed reducer is used for the operation mechanism of large and small cars to facilitate maintenance.

4.Equipped with anemometers, lightning rods, anchors, clip rails, and windproof cables.


Specification

With the deterioration of the atmospheric environment, the acid composition in the rainwater increases, and the opencast equipment such as the wharf crane has also caused a little influence, so it is also a key point to prevent corrosion in the maintenance of the wharf crane. The rust prevention of quay crane mainly includes the following points:

 

(1) To remove the damaged part of the film on the metal structure, the surface of the component should be cleaned and painted with antirust paint and decorative paint to protect the metal surface from rust after the rain.

 

(2) In the active part of the crane, such as the connection pin of the sling and the crane, the wheel of the guide wheel and the wheel of the car, the rust prevention work should be done well. After the shutdown, the first brush to brush these parts, remove the corrosion of the impurities, moisture, rust spots and so on for these parts of -10 or -20 diesel oil, because the -10 or -20 diesel oil permeability is stronger than the oil, the load of the stranded parts can penetrate into the metal surface oil film, and because of its oil film, and because of its The freezing point is low, so it can be low at low temperature.

 

(3) After cleaning and lubricating with diesel oil, apply a layer of grease. Calcium or lithium base grease is a good choice, because these two kinds of grease, mechanical stability, adhesion and water resistance performance, solidification point can also reach -20 degrees, coating grease, coating not too thick.
