The utility model relates to a novel lower chamber device, which is characterized in that the lower part is of two caterpillar walking mechanisms, wherein a frame is arranged between the two caterpillar walking mechanisms, a rotation platform is installed above the frame, a cab is arranged on the rotation platform, the rotation platform behind the cab is connected with the lower end of a retractable suspension arm, the rotation platform is provided with a lifting mechanism, and the lifting mechanism is matched with the retractable suspension arm; and the rotation platform is also provided with a retractable-type balance weight mechanism. When the novel lower chamber device is operated in the cabin, the complete extension and complete retraction of the balance weight can be realized. The balance weight is completely extended to improve the hoisting performance; and the balance weight is completely retracted to improve the adaptability to the space.
