Manual G Clamp with 40mm Maximum Opening for Industrial Applications

Product Overview

The 147mm Manual Clamp is a mechanical clamping solution designed for industrial fixing, positioning, and auxiliary holding applications.

The clamp uses a manual mechanical structure to adjust the clamping position, allowing operators to secure different workpieces according to actual production requirements.

The key specifications include:

• Total Length: 147mm
• Maximum Opening: 88mm

Among these specifications, the 88mm maximum opening is the primary selection parameter because it determines the available clamping range for different workpiece sizes.

This manual clamp is suitable for aluminum profile processing, assembly positioning, surface treatment support, and general industrial fixture applications.

Problem | Difficulty Fixing Different Workpiece Sizes

Limited Compatibility with Different Workpieces

In industrial production, workpieces often vary in thickness, width, and shape.

When a clamp has insufficient opening capacity, operators may need to replace clamps frequently for different products.

This increases fixture management complexity and reduces flexibility during production preparation.

Fixed-Size Clamp Limitations

Traditional fixed-size clamps are designed for specific dimensions.

When production requirements change, a limited opening range may cause:

• Incomplete workpiece contact
• Poor positioning
• Additional fixture adjustments

Lack of Flexible Manual Adjustment

Many industrial applications do not require fully automated clamping.

They require:

• Quick adjustment
• Simple operation
• Flexible workpiece adaptation

A manual mechanical clamp can provide this type of solution.

Cause | Why Workpiece Fixing Problems Occur

Maximum Opening Determines Clamp Compatibility

The maximum opening is one of the most important parameters when selecting a clamp.

If the opening is smaller than the workpiece size, effective fixing cannot be achieved.

This model provides:

Maximum Opening: 88mm

which expands the applicable range for different workpiece dimensions.

Production Variety Creates Fixture Challenges

Manufacturers often process multiple product sizes.

A clamp designed for only one dimension may reduce production flexibility.

Engineers should evaluate:

• Maximum opening
• Overall length
• Contact position
• Working space

Solution | 88mm Opening Manual Clamp Design

Larger Opening Range for Flexible Fixing

The key advantage of this manual clamp is:

88mm Maximum Opening

This specification provides more adjustment space compared with smaller opening clamps.

It helps users evaluate compatibility before selecting the fixture.

Mechanical Adjustment Without Additional Systems

The manual mechanical structure does not require:

• Compressed air
• Electrical control
• Hydraulic components

It provides a simple solution for flexible industrial fixing.

147mm Length for Practical Operation

The overall length:

147mm

affects handling space and operation convenience.

The design provides a balance between accessibility and manual adjustment capability.

Specification Table

Application

Aluminum Profile Processing

The clamp can support auxiliary positioning during aluminum profile processing.

The 88mm opening capacity allows more flexibility when handling different profile sizes.

Surface Treatment Support

For surface treatment preparation processes, manual clamps can be used in auxiliary stations where flexible positioning is required.

Assembly and Maintenance

For workshops and maintenance environments, the manual structure allows quick adjustment without additional power systems.

How to Choose the Right Manual Clamp

1. Check Maximum Opening

Confirm the maximum workpiece thickness first.

This model provides an:

88mm Maximum Opening

which should match the required clamping distance.

2. Evaluate Clamp Length

The total length affects operation space.

The 147mm length provides practical handling for manual applications.

3. Match Clamp Type with Application

Choose based on production requirements:

• Automated cycles → Pneumatic clamp
• Flexible fixing → Manual mechanical clamp
• Maintenance work → Adjustable manual clamp

FAQ

Q1: What is the maximum opening of this manual clamp?

The maximum opening is 88mm.

This parameter defines the applicable workpiece size range and should be considered before selecting the clamp.

Q2: Why does maximum opening matter?

Different workpieces require different clamping distances.

A larger opening provides more flexibility when handling various dimensions.

Q3: Can this clamp be used for automatic production lines?

This is a manual mechanical clamp.

It is suitable for auxiliary fixing, assembly, maintenance, and flexible production environments.

For high-frequency automatic opening and closing cycles, pneumatic clamps are usually more suitable.

Q4: What information should customers provide before selecting this clamp?

Customers should provide:

1. Workpiece size
2. Required clamping position
3. Operation frequency
4. Automation requirements

Q5: What are the key specifications?

The main parameters are:

• Total Length: 147mm
• Maximum Opening: 88mm
• Manual Mechanical Operation

The 88mm maximum opening is the most important selection parameter.
