のバランス装置。In a gate-shaped machine tool comprising a cross rail that is movable in the vertical direction along a gate-shaped column and a movable body provided on the cross rail so as to be movable in the horizontal direction, a fluid is provided at both ends of the cross rail. A pressure cylinder is provided, a chain wheel is provided at both ends of the gate-shaped column, and the chain wheels are connected to each other by a torsion rod, one end of which is connected to each fluid pressure cylinder, and a chain is placed around each of the chain wheels. While a counterweight is suspended from each end, a gradient cam with a shape calculated and set in advance by displacement corresponds to the load fluctuations of the moving weight of the moving object moving on the crossrail and the balance weight of the crossrail itself. A balance device for a cross rail, characterized in that a plate is provided on the cross rail, and a pressure regulating valve is provided on the movable body for adjusting the pressure of the fluid pressure cylinder according to the shape of the cam plate.
