Ratchet straps and cam straps are both used for securing cargo, but they differ in mechanism, strength, and application.
Ratchet Straps:
- **Mechanism**: Ratchet straps use a ratcheting mechanism to tighten the strap. The handle is pumped back and forth to gradually tighten the strap, allowing for a very secure hold.
- **Strength**: They are generally stronger and can handle heavier loads, often with a working load limit of several thousand pounds.
- **Application**: Ideal for heavy-duty applications such as securing large equipment, vehicles, or heavy cargo. They are commonly used in industrial settings, trucking, and for securing loads on trailers.
- **Adjustment**: The ratcheting mechanism allows for precise tension adjustment, ensuring the load is tightly secured.
- **Ease of Use**: They can be more complex to use and require more time to set up and release compared to cam straps.
Cam Straps:
- **Mechanism**: Cam straps use a cam buckle to secure the strap. The strap is threaded through the buckle and pulled tight by hand, with the cam mechanism holding it in place.
- **Strength**: They are generally less strong than ratchet straps, suitable for lighter loads, typically with a working load limit of a few hundred pounds.
- **Application**: Best for lighter-duty applications such as securing kayaks, bicycles, or camping gear. They are popular for personal use and recreational activities.
- **Adjustment**: Easier and quicker to adjust, as they can be tightened or loosened by simply pulling the strap through the buckle.
- **Ease of Use**: Simpler and faster to use, making them convenient for quick and frequent adjustments.
In summary, ratchet straps are preferred for heavy-duty, high-tension applications, while cam straps are suitable for lighter, quick-use scenarios.
