Heavy Duty Plastic Drag Chain

This heavy-duty cable chain is specially designed for heavy load, long travel and high-dynamic applications. The heavy loading openable or enclosed enery chain is commonly used to protect large-size cables, oil hoses, air pipes and other pipelines, and suitable for extreme industrial environments. Durable and wear resistant cable energy chain features high load-bearing capacity to support heavy cables and pipelines, excellent bending fatigue resistance and strong impact resistance. It is widely applied in ports, mines, metallurgy, energy industry, excavators, cranes, packaging machinery and large cutting machine tools.

Main Features: Why Choose a Heavy-Duty Plastic Cable Carrier?

High Strength & Durability
Made of reinforced nylon and 30% glass fiber material, it withstands high pressure and tensile loads, achieving an ultra-long service life of up to 5 million cycles in continuous reciprocating motion. Compared to metal steel drag chain, it offers better wear resistance, self-lubrication, lower noise, and effective vibration absorption.

Excellent Environmental Adaptability

●Corrosion resistance – Excellent resistance to oil, salt, acids, alkalis, and seawater.

●Wide temperature range – Operates stably from -40°C to +130°C.

●High protection rating – The fully enclosed structure effectively prevents dust, debris, and other foreign matter from entering, protecting the internal cables and hoses.

●Electrical insulation & safety – The material is electrically insulating, avoiding the risk of electric leakage, which offers an advantage in applications with high electrical safety requirements.

●Lightweight & maintenance-free – Lighter than metal cable carriers, making installation easier and reducing equipment energy consumption. No additional lubrication is required during operation, achieving true maintenance-free performance.

Structural Composition: Modularity and Flexibility in Design

heavy loading reinforced nylon energy chain is mainly composed of the following modular components, allowing flexible configuration within limited space:

●Side links (left and right) – The framework that provides structural strength and axial constraints.

●Crossbars (top and bottom covers) – Prevent foreign matter from entering and can be quickly opened to install, replace, or inspect internal cables/hoses.

●Separators – The internal "organizers" that divide the carrier's interior into multiple independent zones, avoiding entanglement or friction between different lines.

●Mounting brackets (connecting heads) – Located at both ends of the cnc hose carrier, used to fix the entire carrier to the equipment. Available in fixed or swivel types.

Common Sizes and Selection Reference

The size of a heavy-duty plastic drag chain is usually specified in the format "inner height × inner width". The key parameters include inner height, inner width, and bending radius.

 Typical Sizes by Inner Height "Series"

Series 55 (45 mm inner height) – Inner width available from 50 mm to 300 mm in various options.
Series 65 (55 mm inner height) – Common inner widths: 50, 75, 100, 125, 150, 175, 200, 250, 300, 350, 400 mm.
Series 80 (80 mm inner height) – Inner widths available: 75, 95, 125, 150, 175, 200, 250, 300, 350, 400 mm.
