NGC’s XCJ series gearboxes with planetary are differential design, applied to four-reel drive systems of bridge grab ship unloaders. The input motions of the lifting motor, open-close motor, and the walking motor are conversed and decomposed into the motion combination with different rotating directions and rotating speeds of the four reels, helping to control a series of operations of lifting, opening, closing, and walking. It thus represents a key piece of equipment for bridge grab ship unloaders.
Center distance of two output shafts: 800 mm～2,800 mm
Maximum torque of single output shaft: 600 kN.m
Transmission ratio i = 11.2～50
Optimized structure, small size, light weight, large load capacity and high reliability
High gear accuracy, high driving efficiency, stable driving, and low noise
Mechanical sealing method is convenient to use and maintain
Gearboxes allow two options: lifting in different directions and lifting in the same direction, so it can meet the different winding requirements of reel mechanisms.
