The product description of Double Girder overhead crane
1.Double girder overhead bridge crane sometimes also called bridge cranes, eot cranes or QD type bridge crane, which are cranes winch traveling along the bridge between parallel runways.
It is composed of main beam, end carriage, hoist or winch, electric power transmission device and operation room.
2.The double overhead bridge crane is widely used indoors, station, port, workshop, plant, stockyard.
Double girder overhead bridge cranes are an excellent choice where high speeds and heavy service are required.
3.There are three control method, Pendent line, Wireless remote control and Operation room.
This overhead bridge crane is suitable for any environment.
4.We can customized overhead crane according to customer need.

Advantages of Double Girder overhead crane
1. Double beam bridge crane is the first honeycomb beam design, with light dead weight, large load, strong wind resistance and other characteristics.
2. Unique steel pin connection, not only firm and reliable, but also short assembly time.
3. Flexible strut legs, site steering can be disassembled into a single piece, easy to transport.
4. The minimum installed capacity solves the difficulty in using electricity for field construction.
Features of Double Girder overhead crane
1. The working class of double-beam bridge crane is divided into A1-A8 classes according to the utilization class (the number of working cycles within the design life period) and load state (nominal load spectrum coefficient).
The technical performance of A5 and A6 standard products is shown in the table. Other work levels require special orders.
2. The double beam bridge crane is composed of four parts: bridge frame, trolley, trolley operating mechanism and electric control equipment.
3. The bridge frame of double-beam bridge crane is a box-type four-beam welded structure with good bearing performance.
The control room is bright and comfortable. Fans, air conditioners and air coolers can be configured according to the needs of users.
4, Double beam bridge crane trolley lifting and running mechanism of the working speed can be changed according to the user's requirements, can be equipped with an electronic scale, there are a variety of speed regulation (including frequency conversion speed regulation) for the user to choose first.Double brakes are provided for cranes that carry hazardous materials and liquid metal.
5, the electrical control of the double-beam bridge crane has two ways of driver's cab control and ground remote control for users to choose first, short circuit protection, loss of voltage protection, over-current protection, boarding chain protection and other safety protection.
Electrical components are selected from well-known domestic products to ensure stable and reliable operation.
6, double beam bridge crane used in the open air crane with large, car rain cover.Lifting weights: 5T, 10T, 16/3.2T, 20/5t, 32/5T, 50/10t, 75/20T, 80/20t, 100/20T, 125/32T, 160/32T, 200/50T, 250/50T, 300/80t, 350/80t, 400/80t
