Four-stage operation
- The grab is lowered onto the material with the jaws open.
- The closing rope is pulled to grip the material.
- Both ropes are pulled synchronously to lift the load.
- The closing rope is released to discharge the load.
Advantages
- Energy-independent operation without a motor, pump or electrical cable
- Mechanical construction suitable for underwater, dusty and severe environments
- Simple maintenance focused on rope inspection and lubrication
- Bucket jaw tips and cutting edges are manufactured from wear-resistant HARDOX material.
Applications
