Gantry Style Robot

The Gantry Style Robot is a double-column, bridge-supported handling system for moving heavy workpieces between machine tools and loading stations. It is used in CNC machining cells, gantry-milling installations and automated plate-transfer projects involving castings, metal sheets or large mechanical components.

Bridge Support for Loads up to 200 kg

Two upright columns support the transfer beam at both ends, with model ratings of 10, 30, 50, 100 and 200 kg. When a heavy blank is lifted away from its fixture, the load is carried through a supported bridge instead of a long cantilever, reducing beam deflection during horizontal movement.

Long-Span Transfer Without Intermediate Setting Down

Available X-axis spans are 1500, 2000, 3000 and 5000 mm. A long-span arrangement can move a plate from a buffer stand across to an adjacent machining station in one programmed transfer, avoiding an extra pickup point between machines.

Drive Selection for Short and Long Axes

Short-travel configurations use ball screws with ±0.02 mm repeat positioning; long-travel configurations use precision helical rack-and-pinion drives with ±0.05 mm repeat positioning. The screw layout supports closely spaced fixtures, while the rack layout maintains commanded travel across wider machine gaps.

Travel Speeds for Inter-Machine Handling

The X-axis operates within a 0.8–1.5 m/s speed range and the vertical axis within 0.5–1 m/s. For plate transfer where the robot must raise the load above machine guarding before moving sideways, the separate lift and traverse motions form a controlled clearance path without manual crane repositioning.

The system is designed from workpiece drawings, maximum suspended weight, machine spacing, lifting height and the foundation layout. We determine the column positions and beam section from the working span, then configure the lifting head, transmission and transfer path for the specified handling duty.

Structural fabrication is reviewed for column geometry, welded connections and beam mounting faces. During assembly, guideways, motion drives and lift supports are inspected at the points where alignment affects travel across the full bridge.

The robot is checked through unloaded travel and controlled workpiece-handling cycles. Verification focuses on end-of-travel alignment, vertical pickup and release, clearance above guards and the behavior of the gripping system during acceleration and stopping.

Each finished gantry receives a pre-packing inspection covering the mechanical structure, control enclosure and operating functions. Third-party inspection is supported, and export protection is confirmed before the machine leaves the factory.
