Combination tools for steel strapping are designed to streamline the process of securing heavy loads with steel straps by integrating three key functions: tensioning, sealing, and cutting.
1. **Tensioning**: The tool first grips the steel strap and pulls it tightly around the load. This is achieved through a tensioning mechanism, often a ratchet or lever system, which allows the operator to apply the necessary force to ensure the strap is snug against the load, preventing movement during transit.
2. **Sealing**: Once the strap is properly tensioned, the tool moves to the sealing phase. This involves crimping a metal seal around the overlapping ends of the strap. The combination tool uses a sealing mechanism, typically a set of crimping jaws, to compress the seal and strap together, creating a secure bond. This step is crucial for maintaining the tension and integrity of the strapping.
3. **Cutting**: After sealing, the excess strap needs to be removed. The combination tool includes a cutting mechanism, usually a built-in blade, to trim the strap close to the seal. This ensures a neat finish and prevents any loose ends that could pose a safety hazard or interfere with handling.
Combination tools are manually operated, pneumatic, or battery-powered, offering flexibility depending on the volume and frequency of strapping tasks. They are favored in industrial settings for their efficiency, as they eliminate the need for separate tools for each step, reducing time and labor costs. The integrated design also minimizes the risk of errors, ensuring consistent and reliable strapping results.
