Grip chains are used for gripping, pulling, and transporting large, thin-walled sensitive materials like plastics, plastic film, and thin sheet metal. Materials that require careful handling to prevent damage during transport, positioning, feeding, pulling, stamping, welding, filling, laminating, cutting, stretching, forming, or sealing.
IWIS grip chains with clamping elements are corrosion-protected, wear-resistant, and come with food-grade initial lubricant. They ensure precise material handling and positioning. The pivoting gripper mechanism secures materials accurately, while variable spring forces provide gentle clamping for different materials.
Technical features Version A
- Single and duplex chain 1/2 x 5/16“ acc. to ISO 606
- Gripper with 1 tip, special designs on request
- Retention force is dependent on material conveyed and spring design – different number of coils and wire spring diameters available
- The gripper opens when it runs against a control disc (e.g. sprocket hub), causing it to swivel away outwards
- Food-grade initial lubrication
- Sprocket designs on request
Technical features Version B
- Single and duplex chain 1/2 x 5/16“ acc. to ISO 606
- Gripper with 2 tips, special designs on request
- Retention force is dependent on material conveyed and spring design – different number of coils and wire spring diameters available
- The gripper opens when it runs against a control disc (e.g. sprocket hub), causing it to swivel away outwards
- Higher retention force in comparison with 1-tip grip chain
- Food-grade initial lubrication
- Sprocket designs on request
Technical features Version C
- Single and duplex chain 1/2 x 5/16“ acc. to ISO 606
- Gripper with flat clamping surface
- Retention force is dependent on material conveyed and spring design – different number of coils and wire spring diameters available
- The gripper opens when it runs against a control disc (e.g. sprocket hub), causing it to swivel away outwards
- Gentle handling of materials
- Low transmission forces
- Sprocket designs on request
Technical features Version D
- Single chain 1/2 x 5/16“ or 5/8 x 3/8“ acc. to ISO 606
- Rotationally symmetrical gripper element
