The main body of the gantry loading system is welded from high-quality structural steel. It undergoes annealing and aging to eliminate internal stress, then coated with anti-corrosion paint to enhance durability. The double-beam truss and vertical dual guide rails ensure high load capacity and smooth, vibration-free movement, making it ideal for heavy-duty sheet metal automation.
This truss transfer system adopts dual vertical linear guides and rack-and-pinion transmission for stable long-distance movement (3–10 meters). It supports X-axis speeds up to 100–150 m/min, with dual-pinion backlash elimination for precision. The track guide model is selected according to payload size, ensuring H-level motion accuracy in automated operations.
The industrial robot controller is equipped with a standard Ethernet interface, enabling real-time communication between the truss loader and CNC bending center. It supports intelligent motion planning, multi-axis synchronization, and full-line automation. This architecture ensures the truss gantry robot can adapt to diverse sheet handling tasks efficiently.
Designed for flat, non-magnetic metal sheets such as aluminum or stainless steel, this system features vacuum pumps (flow rate: 100–500 L/min) and pressure sensors for real-time suction monitoring. The number of vacuum suction cups is customized based on sheet size. It provides large-area grip without surface damage, and adapts to irregular or thin panels—ideal for automatic sheet metal pick-and-place systems.
Optimized for magnetic materials like cold-rolled steel or galvanized steel, these electromagnetic sheet lifters offer powerful gripping force with rapid response time. The magnetic field strength is adjustable from 0–220 V to match various sheet thicknesses. An integrated demagnetization circuit prevents residual magnetism, ensuring safe release and efficient stacking.
These are ideal for handling decorative or coated panels such as furniture boards or appliance casings. The low-adhesion sponge cups prevent pulling or scratching of protective films, ensuring surface integrity during automated unloading. This enhances line efficiency and reduces the need for secondary film handling or rework.

Our machines is suitable for common sheet metals such as stainless steel, carbon steel, aluminum alloy, and galvanized sheet. The thickness range is 0.2mm-6mm, meeting needs of various industries, including home appliances, hardware, and cabinets. It also supports asymmetric and complex customized processes.
Yes, we offer a one-stop service: “on-site installation + commissioning + customized training.” Professional engineers will visit the customer’s site to complete production line assembly and equipment integration commissioning to ensure the line reaches its designed capacity. We also provide theoretical and practical training for operators (6-8 days), covering equipment operation, routine maintenance, and troubleshooting. After the training, we provide an operator manual and video tutorials.
Customized services are available. We will optimize the machine structure based on the customer’s workshop space, load capacity, and processing requirements. While ensuring processing accuracy, we adapt the machine to the shop’s existing power and air supply conditions to ensure smooth installation and efficient operation.
We have established a 24-hour global after-sales response mechanism: Customers can submit troubleshooting reports via phone, email, or online customer service, and a preliminary solution will be provided within 1 hour. If remote debugging is required, an engineer will provide video guidance within 2 hours. For hardware repairs, domestic customers will receive a visit within 48 hours, while overseas customers can use authorized service centers or expedited delivery of parts (with installation instructions) to ensure a quick resolution.
All of our standard equipment (flexible bending centers, CNC turret punch presses, press brakes, and punching and shearing machines) comes with a one-year free warranty. For some products with higher system complexity, the warranty period can be extended to 18 months. The warranty covers repair and replacement of quality issues with core components (such as servo motors, CNC systems, and guide rails), as well as free on-site inspections during the warranty period. Please note that equipment failures caused by human error, force majeure (such as floods and earthquakes), or failure to follow the maintenance manual are not covered by the free warranty, but paid repair services are available.
Extended warranties are available, with coverage ranging from 1 to 3 years. These plans are customized based on the equipment type, frequency of use, and customer needs.

A Gantry Loader is an automated loading and unloading machine designed for efficient material handling in sheet metal production. It uses a gantry robot system to move raw sheets and finished products between CNC machines, bending centers, and laser cutting systems. The loader operates on a rail-mounted structure with vertical and horizontal axes, ensuring fast, precise, and stable positioning.
Integrating a gantry robot system significantly improves automation in sheet metal processing. It enables continuous loading and unloading, increases throughput, reduces labor costs, and minimizes material damage. With features like high-speed motion control and multi-axis coordination, the system ensures accuracy and reliability even in high-volume production environments.
Yes, our gantry loader system is designed with flexible compatibility. It can be tailored to integrate seamlessly with various CNC machines, panel benders, and fiber laser cutters.
