Double Girder Bridge Cranes with Hook (QD Type)
 
QD type is the double girder hook bridge cranes with single trolley. It is available in higher capacities than single girder cranes and for heavy duty applications, they can be supplied with open winch hoists. With high standard classification group, excellent stability and security, Low failure rate are available with a huge range of options.
 
Application Parameters:
Commonly hoisting weight: 5~50 tonnes
Span: 10.5~31.5 meters
Classification Group: A5 ~ A7
lFor A5 class, there is suitable for normal machinery manufacturing, maintenance and assembly workshop, steel structure workshop, etc.
lFor A6, A7 class, there are suitable for recycle producing or transferring required, well enough for the auxiliary lifting of metallurgy foundry. The working environment should be -20ºC~40ºC,relative humidity ≤85%
The trolley running on the girder laying orbit.
working speed can be customized.
12 months Warranty
 
 
One simple advantage of the double girder crane design is the option to fit a walkway to the crane. This gives maintenance access to many critical parts of the crane and often to overhead lighting etc. When the crane need to outdoor working, the rainproof device available for matching.

How to determine the crane classification group?
Average time the lifting unit will be in operation. By referring to table-1 the class of utilization "U" can be obtained against the average utilization time.
Type of duty on which the uplifting unit will be employed. From Table-2 select the most appropriate type of duty and determine the state of loading "Q". with the two factors from table 1and 2 the standard classification group "A" of the lifting unit can be determined.
