The crane is equipped with several key components, including the slewing motor, rotary gear reducer, brake system, slewing ring, and central rotating unit. Some models also feature a slewing buffer valve, which helps to minimize the shock and vibration that occur during rotation, ensuring smoother operation.
Shandong Xinda Crane Factory specializes in manufacturing a wide range of cranes, including small models such as 6-ton, 8-ton, and 10-ton cranes, each available in various specifications to suit different applications. In some models, the operator controls the rotation using a handle located on the left side of the cabin. Pushing the handle forward moves the crane to the right, while pulling it back causes it to rotate to the left. Some configurations allow the left handle to move both to the right and to the left, providing more control options. When the handle is in the neutral position, the rotation stops. While most models allow full 360° rotation when unloaded, load rotation may have specific restrictions depending on the model and its design.
The operation of the crane's swing mechanism typically involves a control handle positioned in the driver’s cabin, which is usually located on the far left front side. This handle is used to control the rotation direction—pushing it forward results in a rightward turn, while pulling it back causes a leftward turn. To stop the rotation, the handle can be returned to the neutral position or the brake pedal can be engaged. On certain models, such as those in the K series, the left-hand control lever is specifically designed for rotation. Moving the handle to the left initiates a left turn, moving it to the right initiates a right turn, and placing it in the center cuts off the rotational power. These features ensure precise and safe operation, making the crane suitable for a variety of industrial and construction tasks.
