Hoist Gear Box Reducers

The crane reducer is a standard reducer dedicated to the crane industry. It is called the "QY" series. It is widely used in bridge cranes, door cranes, beam cranes, shiplifts, and closed -closing machines. The basic models are: QY3S, QY3D, QY4S, QY4D, QY34S, QY34D. There are 15 specifications in the entire series: 160, 180, 200, 225, 250, 280, 355, 400, 450, 500, 560, 630, 710, 800. The crane reducer uses a three-level or four-level hard-to-to-to-to-to-tank cylindrical gear. The transmission ratio is: 16-500, and the output torque: 2800Nm-355000Nm. All the boxes are welded with steel plates, and the gears are all low-carbon alloy steel, carburizing quenching, HRC54-62. After grinding tooth processing, the accuracy is 6, the weight is lighter, and the operation is reliable. There are many options for the low -speed axis of the crane reducer: cylindrical shaft (type P), flower keys axis (H type), and gear shaft extension (type C). The crane reducer should be selected according to the wor…
