(N)GRDGÖU Heavy Duty Flexible Cable for Port Machinery
When it comes to port machinery, industrial equipment, or large-scale material handling, choosing the right cable can make or break the operation.
In these heavy-duty environments, where mechanical stress, frequent bending, and extreme conditions are everyday challenges, you need a cable that is reliable, flexible, and durable.
The (N)GRDGÖU Heavy Duty Flexible Cable is a high-performance, low-voltage power and control cable designed specifically for port machinery, cranes, hoists, and transporting machines.
Whether you're working in dry, damp, or wet industrial conditions, this cable can handle the demands of lifting devices and heavy machinery.
In this article, we’ll dive deep into the features and benefits of the (N)GRDGÖU Cable, explain how it compares with NSHTÖU Cable, and outline why this cable is your best choice for heavy-duty port applications.
You’ll also learn how this cable stands out as an oil-resistant flexible cable, ideal for outdoor use and other demanding environments.
A Brief History of (N)GRDGÖU Cables
The (N)GRDGÖU Heavy Duty Flexible Cable has a legacy of performance, born out of necessity for robust cabling solutions in industrial applications.
Over the years, technological advancements in materials and cable construction have led to the development of high-flexibility cables designed to endure the mechanical stresses and environmental challenges in port operations.
Initially, cables like NSHTÖU were developed to serve industries requiring flexibility and durability.
However, as the demand for more specialized solutions grew, the (N)GRDGÖU Cable emerged as a heavy-duty flexible cable that could offer superior performance in cold temperatures, under high tensile stress, and in conditions where frequent bending is unavoidable.
(N)GRDGÖU is designed for industries that need more than just standard performance — they need cables that can withstand constant movement, twisting, and extreme weather conditions.
Why (N)GRDGÖU Cable Stands Out
The (N)GRDGÖU Cable is crafted to provide superior flexibility and mechanical strength, making it a top choice for port machinery and lifting equipment. Let’s explore the key features that make this cable exceptional:
1. Engineered for Heavy Mechanical Loads
In environments like ports and large industrial facilities, cables often face heavy mechanical loads. Whether it's a crane cable that undergoes reeling or a port machinery cable subjected to frequent lifting, the (N)GRDGÖU Cable is built to handle intense mechanical stress.
Its construction includes an antitorsion textile braided sheath that prevents twisting and damage during operation.
This cable excels under high tensile load, making it ideal for festoon systems where cables are frequently reeled and unreeled. The (N)GRDGÖU Cable equivalent stands out by being able to endure loads that other cables would not be able to sustain.
2. Flexibility in Extreme Conditions
One of the standout qualities of the (N)GRDGÖU Cable is its flexibility, even in extreme cold or heat. With a working temperature range of -40ºC to +80ºC for fixed installations and -25ºC to +80ºC for mobile use, this outdoor flexible cable is designed to function reliably in harsh environments.
This flexibility ensures that the cable can maintain its integrity during frequent bending and movement.
Whether you are operating in wet conditions, exposed to oils, or under high mechanical strain, the (N)GRDGÖU Cable proves its worth by delivering consistent, reliable performance.
3. Oil Resistance for Industrial Settings
Industrial environments can expose cables to oils, chemicals, and other substances that may degrade their materials. The (N)GRDGÖU Cable is classified as an oil-resistant flexible cable for outdoor use, meaning it has been tested to withstand exposure to oils and lubricants commonly found in port machinery and industrial environments.
With compliance to DIN VDE 0473-811-2-1, this cable is designed to resist oils, extending its lifespan and maintaining performance even in oil-heavy environments.

This comprehensive technical performance makes the (N)GRDGÖU Cable for crane applications an indispensable asset in heavy machinery operations.
Applications of (N)GRDGÖU Cable
The versatility of the (N)GRDGÖU Cable makes it suitable for a wide array of industrial applications, including:
Crane cable for port machinery and lifting systems
Flexible low voltage power and control cable for transporting machines
Reeling cables in hoisting plants where frequent bending is required
Port machinery cable designed for handling high mechanical stresses in industrial environments
Material handling equipment, where cables need to endure oil exposure and mechanical strain
For operators working in wet industrial conditions, the oil-resistant flexible cable is particularly useful, as it ensures long-term performance even in environments exposed to moisture and lubricants.
(N)GRDGÖU Cable vs. NSHTÖU Cable: What’s the Difference?
At a glance, the NSHTÖU Cable and the (N)GRDGÖU Cable might seem similar, but there are critical differences that make each suited for different applications.
The NSHTÖU Cable is excellent for environments where flexibility is key, particularly under moderate mechanical loads. However, the (N)GRDGÖU Cable takes it a step further by being optimized for heavy mechanical loads and high tensile stress.
This makes it the superior choice for applications in port machinery, lifting devices, and transport systems where cables are exposed to extreme mechanical forces and need to perform consistently.
While both cables offer oil resistance, the (N)GRDGÖU Cable is specifically designed for outdoor use under severe mechanical strain, which is why it is preferred for crane cable and festoon system applications.
