1t~20t LDA Model Single Girder Overhead Crane(Bridge Crane):

1.LDA modelsingle girderoverhead crane(bridge crane) is improved and designed on the basis of LD model overhead crane.

2. Thisoverhead crane(bridge crane) is characterized by more reasonable structure and higher strength steel as a whole, the main beam and end carriage are made by U-section steel plate.

3. This overhead crane (bridge crane) is used together with CD1/MD1 model or HC/HM model wire rope electric hoist as a complete set.

4. This overhead crane is medium duty class overhead crane, the capacity from1ton to 20 tons. The span from 7.5m to31.5m, the working grade is A3-A4. Working temperature within -25 to +42 centigrade.

5. This overhead crane (EOT crane) is widely used in plants, warehouses, material stocks to lift goods. It is prohibited to use the equipmenmt in the combustible, explosive to corrosives environment.
