Brief Introduction:

Double girder electric overhead crane has the advantages of compact shape dimension, low building headroom height, light weight,small wheel pressure and so on. It uses together with CD1 or MD1 electric hoist. It is suitable for transporting, assembling ,repairing and load; unload works in mechanical processing workshop,metallurgy auxiliary workshop, storage, yards, power station and so on. It can replace normal double-beam bridge crane and being used in workshop of textile industry and food industry. The work type can be divided into two kinds- light class and intermediate class, the temperature of working environment is -25ºC-40ºC.

Safety Devices for overhead bridge crane:
To guarantee the normal operation of crane and avoid the personal casualty and mechanical damage, the safety device we provide are not only the electric protective devices or alarm bell but also other equipments as following:
1. Overload Limit Switch
2. Rubber Buffers
3. Electric Protective Devices
4. Emergency Stop System
5. Voltage Lower Protection Function
6. Current Overload Protection System
7. Rail Anchoring
8. Lifting Height Limit Device


Advantages of a single girder design:
1) Less expensive due to a simpler trolley design, reduced freight costs, simplified and faster installation, and less material for the bridge and runway beams.
2) Most economical option for light to medium-duty cranes
3) Lower loads on the building structure or foundations due to a reduced deadweight. In many cases, it can be supported by existing roof structure without the use of additional support columns.
4) Better hook approach for both trolley travel and bridge travel
5) Easier to install, service, and maintain
6) Ideal for workshops, warehouses, material yards, and manufacturing and production facilities
7) Lighter load on runway rails or beams means less wear on the beams and end truck wheels over time
8) Great for facilities with low headroom
