Pulling and support grips are mechanical devices designed to securely hold, guide, and manage cables and wires during installation, maintenance, or transportation. These tools ensure safe and efficient handling of cables, preventing damage from tension, bending, or environmental factors. Their importance in modern infrastructure such as telecommunications, energy distribution, and industrial automation is critical for ensuring operational reliability and compliance with safety standards.

Type	Functional Features	Application Examples
Pulling Grips	High-tensile strength, anti-slip surfaces, adjustable clamping	Long-distance cable laying in conduits
Support Grips	Load distribution, vibration resistance, 360 rotation	Overhead cable suspension in data centers
Combination Grips	Integrated pulling and support functions	Complex installations in power plants
Rotary Swivel Grips	Twist elimination during pulling	Submarine cable deployment
Heavy-Duty Grips	Reinforced alloy construction, shock absorption	Mining and offshore oil platforms

A typical grip assembly includes:

• Gripping Section: Textured jaws or braided sleeves for friction control
• Linkage Mechanism: Steel chains, polymer ropes, or articulating joints
• Load-Bearing Core: Forged alloy or composite materials for stress distribution
• Protective Coating: Rubberized or polymer layers for abrasion resistance

Parameter	Description	Importance
Max Pulling Force (kN)	Rated load capacity before deformation	Determines suitability for high-tension tasks
Material Yield Strength (MPa)	Structural integrity under stress	Ensures safety in extreme conditions
Operating Temperature (- C to + C)	Thermal stability range	Prevents failure in variable climates
Cable Diameter Range (mm)	Adjustable grip sizing	Enables compatibility with diverse cables
Corrosion Resistance Rating	Exposure tolerance to moisture/chemicals	Extends service life in harsh environments

Key industries and equipment:

• Telecommunications: Fiber optic cable installation vehicles
• Construction: Bridge-mounted cable trays
• Energy: High-voltage submarine cable laying systems
• Manufacturing: Robotic cable management arms
• Transportation: Railway signal cable retention systems

Manufacturer	Representative Product	Key Features
Panduit	Grip-Lok Pulling Grips	Self-tightening design, 50kN capacity
HellermannTyton	Globalgrip Support Clamps	Vibration-damping polymer construction
Cablofil	SteelMate Cable Ratchets	Corrosion-resistant zinc plating
Southwire	PowerGrip Rotary Pullers	Integrated swivel mechanism for twist control

Key considerations:

• Load Requirements: Match grip capacity to cable weight and tension (e.g., 30kN grip for 240mm power cables)
• Environmental Factors: Choose UV-resistant models for outdoor use
• Cable Compatibility: Verify diameter range and jacket material sensitivity
• Safety Standards: Ensure compliance with OSHA 1910.331 or IEC 61436
• Operational Efficiency: Opt for quick-release mechanisms in frequent adjustment scenarios

Case Study: A data center deployed HellermannTyton's Globalgrip clamps to reduce cable sag in overhead trays, achieving a 40% improvement in airflow management.

Future developments include:

• Integration of smart sensors for real-time tension monitoring
• Adoption of carbon fiber composites for weight reduction
• Modular grip systems enabling tool-less reconfiguration
• Growing demand for eco-friendly recyclable polymer grips
• Standardization of grip dimensions for global interoperability
