Contrx double girder bridge cranes are used when capacity and span requirements are too great for a single girder crane to be used. Double girder cranes also provide higher hook heights because the hoist is placed between the cross girders as opposed to under the cross girder. Double girder cranes are also excellent solutions for handling large loads with long spans.
Duty Cycle Duty cycle CMAA Classifications (HMMI similar classifications using H1 –H5) Class A (Standby or Infrequent Service – irregular occasional use followed by long idle periods which rarely hoist the rated load, and normally loads of about 1/3 of the rated load.)
Crane duty classification is according to the grades of crane use (in the whole design life cycle total working cycles) and crane load condition, or to say, crane service classifications is that crane heavy degree of parameters, namely that the extent of the crane work on time and hoisting load parameters.
