Gantry Manipulator

The Gantry-Style Truss Manipulator is a large-stroke, high-rigidity automated loading and unloading system for batch production on CNC lathes, machining centres, and drilling centres. It uses a dual-beam gantry structure. Unlike standard single-arm gantries, it has much better rigidity, longer reach, higher load capacity, and more stable running. It can serve one machine, two machines, or multiple workstations.

This system is mainly used for loading, unloading, and collecting medium to large, heavy metal parts. It is widely used in heavy-load, high-volume CNC processing like auto parts, hardware, and mechanical components. It can run long hours without an operator.

Zhejiang Luban has strong experience with gantry-style systems. We have a 2,450-m² assembly plant and a 1,000-m² sheet metal workshop with machining centres, laser cutters, and press brakes. This ensures the manufacturing precision and assembly quality of every gantry.

Loading and unloading heavy parts is one of the most labour-intensive tasks in CNC machining. A part weighing several dozen kilograms must be carried from the rack to the machine, clamped, and then carried away after processing. This is tiring and inefficient. If a standard light gantry is used for heavy parts, it lacks rigidity and deforms. Precision is lost over time.

The Gantry-Style Truss Manipulator solves this with a dual-beam structure. The integrated dual-beam welded structure has high load capacity, strong bending resistance, and is very stable. Heavy-load running has no sagging, deformation, or resonance. Long-term, high-speed running maintains stable precision. This is ideal for heavy parts and long-span workstations. One auto parts customer told us that after using this gantry, the heavy loading and unloading work that needed two full-time workers became fully automatic. Their single machine's daily output increased by over 25%. Workers' physical workload also dropped a lot.

The gantry uses X, Y, and Z three-axis servo coordination. The X-axis travels along the gantry beam. The Y-axis moves front and back. The Z-axis reaches horizontally. It takes parts from the magazine or frame and moves precisely to the machine door. When the machine finishes and opens the door, the robot removes the finished part and loads the new one.

All three axes use high-power servo motors with heavy-duty precision guides and widened slides. Load capacity is high and gripping is stable. The control uses a Delta gantry system with a 7-inch touch screen teach pendant. Speed can be adjusted to match the part and machine cycle. The multi-layer magazine uses a modular design. Layer spacing can be adjusted for different part sizes. Tray repeat positioning accuracy is within ±0.25 mm. The working temperature range is -10°C to 45°C.

The body uses an integrated dual-beam welded structure that has been stress-relieved. It has high load capacity and strong bending resistance. Compared to standard single-arm gantries, heavy-load running has no sagging or deformation. The long gantry stroke can easily cover one machine, two machines, or multiple workstations on a line. Safety features include a fence, emergency stop, sound and light alarms, and dual hardware and software collision protection. The running area is fully enclosed. If there is a stuck part, overload, interference, or signal problem, it stops immediately.
