Outdoor door hangers have a relatively poor environment because of the relative conditions of the interior. Therefore, the power supply performance of the door hangers is required to be higher. Many customers purchase the power supply methods for the door hangers, mainly the reel cables. The cost of the reel cable is low, but the use effect is very bad. From the perspective of recent customer feedback, many customers have the intention to change the reel cable to the trolley contact line. This article introduced the introduction of the transformation of the power supply mode of the outdoor gantry crane trolley line.
1. The installation method of the outdoor door hanging trolley can be used in two ways: The first one is overhead installation, that is, erecting a power pole or steel column next to the track of the door hanger, laying the track above the steel column, and then again Welded steel angle brackets were welded and the trolley wires were installed in the normal sequence. The second method is to use a trench-type upper edge installation method to dig a drainage ditch on the side of the door hanger track, the depth can be determined according to the actual situation, and then, welding or fixing the sliding contact on the door hanger rail or rail pressure plate. Wire angle brackets are then installed in the normal installation order of the trolley wires.
2. Outdoor track cranes generally have a long track travel distance. When selecting trolley wires, voltage drops and power supply points must be considered. In addition, the general tonnage of the room gantry crane is relatively large. Under normal circumstances, it is necessary to configure dual collectors to enhance its power supply capacity.
3, for the room gantry crane in the selection of safe trolley wire at the same time, you can also consider the tram line, tram line is also a way to consider the outdoor gate crane power supply, but the tram line in the outdoor gantry crane application is relatively less.
