TONGLI assisted lifting manipulators help operators lift, position and transfer materials with less manual effort. Customized arms and gripping tools support different load shapes, workstations and handling tasks—bringing practical automation to your workshop.
VIEW MANIPULATORSSheet Metal Handling Manipulator
Sheet Metal Handling Manipulators have evolved into high-precision, “Zero-Gravity” systems specifically engineered to protect the integrity of delicate surfaces while managing the significant physical demands of heavy plate transport.
Whether loading laser cutters, CNC punch presses, or shearers, these systems eliminate the risk of surface scratches, buckling, and operator injury.
System Architecture
A typical sheet metal handling system utilizes a Rigid-Arm (Hard-Arm) configuration. This is critical because sheet metal often involves large eccentric loads and requires precise horizontal-to-vertical tilting.
Main Structure: High-tensile aluminum or carbon-fiber reinforced booms to minimize rotational inertia.
Balancing Unit: Precision pneumatic cylinders or servo-electric actuators for weightless movement.
EOAT (End-of-Arm Tooling): Multi-zone vacuum suction matrices designed to handle various plate dimensions.
Mounting Options: Floor-mounted pillars, overhead rails (for large workspace coverage), or mobile bases for cross-station flexibility.
Technical Specification Matrix
| Feature | Industrial Specification | Notes |
| Max Payload | 50kg∼600kg | Customizable for heavy plates |
| Effective Radius | 2,500mm∼4,000mm | Overhead rail options for 10m+ |
| Tilting Range | 0∘∼90∘ (Pneumatic/Electric) | For loading vertical racks |
| Positioning Accuracy | ±0.5mm | Haptic-guided fine adjustment |
| Suction Cup Type | Non-marking Polyurethane | Oil-resistant and “Zero-Stain” |
ROI & Safety Protocols
Productivity: One operator can load a laser cutter in < 45 seconds, a task that previously required two people and a slow overhead crane.
Safety (Fail-Safe): In the event of a power or air supply failure, a Vacuum Reservoir Tank maintains suction for at least 20 minutes, while a mechanical safety check-valve prevents the arm from dropping.
Ergonomics: Reduces the risk of “Sheet Metal Cuts” and back strain. The operator applies less than 20N, of force to move a 300KG plate.
Common Application Scenarios
Laser/Plasma Cutting: Rapid loading of raw sheets and unloading of finished “skeletons.”
Press Brake Bending: Supporting large sheets during the bending process to prevent the “whip” effect.
Vertical Storage Racks: Tilting sheets 90° to move from horizontal pallets to vertical sorting systems.
