The Under Slung Crane is designed in the capacity range from 250kg to 10MT. The Under Slung Crane enables precise control of the up/ down motion or travel motion by fitting Variable Frequency Drives in the panels. The Single/ Double Girder Under Slung Crane enables control either through a pendant push button station or a radio remote control.
