These 2 sets of 60+60 Ton Double Girder Gantry Cranes will be used in I-shape concrete Beam precast yard for precast beams handling and the max. Lifting load is 80 tons.
Customer requirements:Synchronous operation: the 2 sets of 60+60 Ton Double Girder Gantry Cranes are running on same rails, Synchronous operation is required for 2 cranes, 2 trolleys on same cranes, 4 trolleys on the 2 cranes. Our solution：In order to better fulfill this requirement, our engineers suggest PLC control system.
1. SEW brand for trolley traversing and crane traveling: we suggest SEW brand drive for trolley traversing and crane traveling to meet crane have duty use, also this will be helpful for crane maintenance.
2. VVVF speed for trolley traversing and crane traveling: Here our engineers suggest variable speed by VVVF for trolley traversing and crane traveling, to make sure smooth performance.
