The invention provides a balance weight mechanism used in an engineering machine which includes a rotating bench and a winding system connected thereto. The balance weight mechanism comprises: two balance weights which are arranged symmetrically relative to the width direction of the winding system and are respectively pivotedly connected to the winding system; and a driving apparatus, of which one end is pivotedly connected to the winding system and the other end is respectively connected to the two balance weights drivingly for driving the balance weights to rotate within the planar surface relative to the winding system. The balance weight mechanism can solve the problem of a poor whole stability in the prior art.
