Gantry Moving Hydraulic Press

The pressing-head of machine can move in three dimensions and reach any positions within the effective rang of working table ,to straighten structure pieces ,level middle thickness plate and shaft as well as their bending ,drawing and pressing .
The unique micro-moving technique of machine has downwards control of the pressing-head with precision and adopts to press the work-piece precisely .
The machine was developed by our company in 1987 .the primary type presents one gantry equipped with one pressing-head ,while the deriving types including double gantries with a couple of pressing-heads, four pressing-heads and multi pressing-heads as well as the widened and lengthened working table types .the machine are widely used in engineering machinery ,train ,auto ship ,petroleum ,metallurgy ,chemical engineering ,and aero plane fields .
