gh40840

The GH40840 toggle clamp is a mechanical device designed to securely hold workpieces in industrial and workshop environments. While specific details may vary by manufacturer, this guide synthesizes available information to provide a detailed overview of its design, applications, and functionality.

1. Overview

Toggle clamps are lever-operated tools that use a linkage system to generate high clamping force with minimal manual effort. The GH40840 model is typically a horizontal-action toggle clamp, ideal for applications requiring quick, repetitive clamping and release. It is commonly used in welding, woodworking, metal fabrication, and automotive industries.

2. Design and Components

The GH40840 features a robust design with the following components:

  • Handle: Ergonomically designed for manual operation, often coated for grip.
  • Clamping Arm: Adjustable arm with a padded or serrated end to grip workpieces.
  • Linkage System: A pivoting mechanism that amplifies force via over-center locking.
  • Base Plate: Mounting base with pre-drilled holes for secure installation.
  • Spring Mechanism: Ensures quick release and return of the clamping arm.

Materials: Typically constructed from carbon steel or alloy for durability, with optional anti-corrosion coatings.

3. Technical Specifications

While specifications vary, common features include:

  • Clamping Force: Up to 2,000 N (approximately 200 kg).
  • Throat Depth: ~40–80 mm (adjustable based on model).
  • Stroke Length: 25–40 mm (travel distance of the clamping arm).
  • Operating Temperature: -20°C to 120°C.
  • Weight: 0.5–1.5 kg, depending on size.

Note: Exact specs should be verified with the manufacturer.

4. Applications

The GH40840 excels in scenarios requiring rapid, secure holding:

  • Welding Jigs: Stabilizes parts during welding.
  • CNC Machining: Secures materials to prevent movement.
  • Assembly Lines: Facilitates repetitive tasks in automotive manufacturing.
  • Woodworking: Holds materials during cutting or sanding.

5. Advantages

  • Quick Operation: Lever action enables fast clamping/unclamping.
  • High Force Amplification: Minimal effort generates significant holding power.
  • Durability: Robust construction withstands heavy-duty use.
  • Adjustability: Customizable stroke and clamping pressure.

6. Installation and Usage Tips

  • Mounting: Secure the base plate to a flat, stable surface using bolts.
  • Alignment: Ensure the clamp arm aligns with the workpiece to avoid uneven pressure.
  • Maintenance: Regularly lubricate pivots and inspect for wear.
  • Force Adjustment: Modify the clamping arm length or spring tension as needed.

7. Safety Considerations

  • Avoid exceeding the maximum load capacity to prevent mechanical failure.
  • Wear protective gloves when handling sharp workpieces.
  • Periodically check for loose components or fatigue in the linkage system.

8. Purchasing Information

The GH40840 is available through industrial suppliers like Alibaba, Amazon Industrial, and specialized manufacturers (e.g., DE-STA-CO, Carr Lane). Prices range from 20–80, depending on specifications and quantity. Always request a datasheet to confirm compatibility with your application.

Conclusion

The GH40840 toggle clamp is a versatile, heavy-duty tool suited for diverse clamping tasks. While its exact specifications depend on the manufacturer, its design principles align with industry standards for reliability and efficiency.
