Across the world, RUD lifting points and chains are known for their pink colour (Often referred to as pinkies in Australia). Ever wonder why the colour pink? Read the story of how the RUD pink colour came to be and our 30-year journey since 1994.
The article below summarises the interview conducted with Hermann Kolb, Head of the RUD Group’s Lifting and Lashing Equipment Division in Germany. The original interviews can be read here and here.
In the world of lifting and lashing equipment, functionality and safety reign supreme, and branding takes second place. Yet, for the past three decades, RUD has broken the mould, blazing a new path with its signature pink colour for its lifting, lashing and chain products.
What started as a bold design choice in 1994 has become an industry-defining trademark. From technological advancements to innovative safety measures, RUD's pink lifting and lashing points and chains have reshaped the perception of industrial equipment while reinforcing the brand's commitment to excellence.
The Beginning of an Unmistakable Trademark
The story of RUD's pink lifting equipment began in 1994 with the development of the world’s first Grade 100 chain system. This ground-breaking advancement represented a significant leap in strength and durability, but RUD wanted to ensure it would also stand out visually in a traditionally conservative industry. Opting for colour as the differentiator, the company chose pink - a decision that was as daring as it was unconventional.
According to Hermann Kolb, the Head of RUD Group’s Lifting and Lashing Equipment Division, the colour pink was associated with progressiveness and modernity, making it an ideal choice to signal innovation. The new design was paired with the product designation VIP 100, where "VIP" stood for Verwechslungsfrei in Pink (non-mix-up in pink). The colour initially sparked internal debate, but it was embraced by employees and stakeholders who saw its potential to redefine RUD’s market presence.
Overcoming Industry Stereotypes
Launching pink-coloured lifting chains in a male-dominated, function-over-form industry came with its challenges. However, the team at RUD was determined and refused to compromise on the new colour.
Even after the initial scepticism, the decision to continue with the pink colour was challenging. “A RUD chain is a RUD chain,” Kolb states, reinforcing the company’s commitment to its brand identity. Over time, the pink colour gained acceptance, and customers began to associate RUD with pink lifting and lashing equipment - a connection that has strengthened the brand over the years.
Function Meets Form - Pink as a Safety Indicator
Beyond its aesthetic appeal, the pink coating on RUD’s products serves a critical functional purpose. When exposed to high temperatures exceeding 200°C, the colour darkens progressively, offering a visual indicator of heat exposure. This feature allows users to assess whether a component has been compromised and should be replaced. A brown-black colour, for instance, signals that the material has surpassed 300°C, potentially reducing its strength and requiring immediate replacement.
This innovative approach has set RUD apart in the industry. It provides an additional layer of safety while enhancing the practical value of its products. The heat-responsive colour chart developed by RUD is now a standard tool for professionals who rely on these components.
The Journey from Grade 100 to Grade 120
RUD’s commitment to innovation is reflected not only in the functionality of its products but also in the evolution of its iconic colour. The original, light pink, represented Grade 100 and remained the standard from 1994 until 2007. As RUD introduced Grade 120, we needed to differentiate the higher grade, which is why all ICE 120 products come with a darker shade called ICE pink. This subtle yet effective variation shows the quality differentiator for clarity.
Powder Coating - Durability Under Pressure
RUD’s pink coating is applied using advanced powder-coating technology, ensuring resilience against the rigours of industrial use. To further reinforce product traceability and safety, RUD incorporates permanent embossing such as manufacturer details, quality class, and batch numbers.
Customisation for Diverse Needs
While pink is RUD’s standard colour, we also cater for customer-specific requirements. Weldable lifting points are often integrated into machinery and vehicles, and in such cases, we offer customised coatings to match product functionality with ambience.
Similarly, our anchor points for personal fall arrest, such as the PSA VRS-STARPOINT or the PSA INOX-STAR, come in yellow. Although this colour is not dictated by any formal standard, it has become an industry norm, providing a clear visual distinction for components designed to secure people instead of lifting or lashing.
Market Reception and Customer Engagement
RUD launched the pink colour in 1994 at the Hanover Fair. Since then, trade fairs and conferences have proven to be important platforms to showcase the pink lifting and lashing equipment. The striking colour often sparks curiosity among visitors and initiates conversations, which has transformed the colour into a recognised brand identity.
Kolb, reflecting on the 30-year journey, affirms that, in hindsight, the decision was perfect and would be made again without hesitation. “We exceeded our expectations. The association ‘RUD = pink’ has achieved an extremely high level of acceptance, and I believe this will remain the case for a long time to come.”
The Future of Pink Innovation
As RUD celebrates 30 years of pink lifting points and chains, we continue to expand boundaries in safety, quality, and design. The enduring success of the pink colour branding demonstrates strategic foresight in shaping market perception.
In an industry driven by performance and reliability, RUD’s pink lifting equipment stands as a testament to the value of innovation - not just in technology but also in how a company chooses to define itself. For professionals worldwide, and especially in Australia, where "Pinkies" are a standard, RUD’s vibrant legacy is poised to continue for decades to come.

Load securing during transportation faces many challenges, especially when dealing with loads that have sharp edges. The sharp edges pose a risk to the integrity of lashing equipment and can potentially lead to accidents, jeopardising the safety of vehicle occupants and other road users. Hence, understanding the potential dangers associated with sharp edges is critical to ensure safe and efficient transportation. Read Part 2 below.
Reduction of Lashing Capacity
With loads where the lashing chain goes over sharp edges, we recommend reducing the Lashing Capacity (LC) by 25% or using a larger chain size. The Load Restraint Guide 2018 of the National Transport Commission (NTC) outlines the rules for lashing loads with sharp edges.
For example, if a lashing chain has a rated capacity of 10,000 daN, the effective securing capacity with a sharp corner load would be reduced by 25%, to 7500 daN.
ICE Grade 120 Lashing Chains
ICE Grade 120 lashing chain can replace a Grade 80 lashing chain of the next largest nominal thickness in direct lashing. ICE 120 is lighter than Grade 80 by 45% and has a breaking force up to 60% higher than Grade 80. This means that by using an ICE 120 lashing chain, you can have a large weight reduction with easier assembly and better safety.
How can Endless Chains help?
In situations where suitable lashing points are unavailable or the existing points are unsuitable, using hooks or shackles for connecting the lashing chain can expose the connecting element to bending stresses. This can compromise the integrity of the connection and lead to potential failure.
Endless chains, designed to eliminate the need for separate hooks or shackles, provide a safer alternative. With an endless chain, the lashing capacity remains consistent throughout the entire chain loop, eliminating the potential weak points associated with hooks or shackles. Moreover, doubling up an endless chain reduces the effects of sharp edges, as the load is distributed across a larger surface area, which limits the stress on individual chain links.
ICE-Endless-Chain and ICE-Multi-shortening Claw
When combined with the ICE-Endless Chain, the ICE-Multi-shortening claw forms a closed chain system that is easily adjustable and can be opened without tools. This flexibility allows for convenient use in situations where the load's dimensions may vary. This configuration is particularly beneficial for securing loads with unconventional shapes, such as stone blocks or concrete, which may lack dedicated lashing points.
The advantages of such a configuration are:
Conclusion:
Understanding and addressing the challenges posed by sharp edges during load securing is crucial for ensuring safe and efficient transportation. By implementing the guidelines of the Load Restraint Guide and utilising appropriate protective measures such as edge protectors and endless chains, we can effectively mitigate the risks associated with sharp edges, ensuring the integrity of the lashing equipment and the safety of all road users.

Load securing during transportation faces many challenges, especially when dealing with loads that have sharp edges. The sharp edges pose a risk to the integrity of lashing equipment and can potentially lead to accidents, jeopardising the safety of vehicle occupants and other road users. Hence, understanding the potential dangers associated with sharp edges is critical to ensure safe and efficient transportation.
Sharp edges can cause considerable wear and tear on lashing equipment, primarily due to the concentrated stress they can impose on the lashing material. The repetitive bending and flexing of the lashing equipment as it goes over these edges can lead to fatigue, weakening the material and potentially causing failure. This failure can result in a sudden snap, a gradual weakening, or a distortion in the equipment's shape, resulting in a compromised load restraint system and a potential safety hazard.
In this article, we will address the question of what is considered a sharp edge and what measures should be taken to ensure safety when working with such angles.
Australian National Transport Commission and sharp edges
The National Transport Commission (NTC), in its Load Restraint Guide 2018, emphasises the importance of protecting lashing chains from sharp edges. This guide outlines a clear correlation between the sharpness of a corner and the chain's lashing capacity, highlighting the critical need to consider the load's geometry when selecting and using lashing equipment.
As per the guide, the lashing chain should be protected over sharp edges or rough surfaces to maintain its full lashing capacity.
When the corner radius (r) is less than the chain size (d), the chain's lashing capacity is reduced by 25%. The above figure is taken from the Australian Load Restraint Guide 2018.
Understanding the Corner Radius and Chain Diameter
When assessing load-securing options, the radius of the sharp edge should be considered in relation to the degree of flexibility of the lashing equipment. The corner radius (r) refers to the radius of the curve at the corner of the load, while the chain diameter (d) refers to the diameter of the chain link. Understanding the relationship between the two is critical because it influences the choice of lashing equipment.
To ensure safe and effective load securing, the corner radius should always be greater than the chain diameter. This ensures smooth chain movement over the corner without any risk of jamming, kinking, or undue stress. When the corner radius is less than the chain diameter, the chain experiences increased bending stress, leading to potential damage and reduced functionality.
Protective measures must be implemented to reduce the risk when the corner radius is smaller than the chain diameter. Edge protectors are an excellent option because they serve as an intermediary between the chain and the load, preventing direct contact and protecting the chain from premature wear and tear.

Risk Analysis: A Crucial Step for Integrated and Attachable Lifting Points
A comprehensive risk analysis is mandatory before conducting a lift, whether utilising integrated or attachable lifting points. This analysis should consider the following key aspects regarding lifting points:
Lifting Point Selection Criteria
Choosing the appropriate lifting point is crucial for ensuring the safety and efficiency of any lifting operation. Here are some key factors to consider during the selection process:
Verification and Documentation
The selected lifting point should possess a valid test certificate conforming to the relevant standards. This certification verifies that the manufacturer adheres to stringent testing protocols, including proof load application, destructive tensile tests, and crack detection procedures.
Design and Calculation Resources
Providing engineers access to 2D/3D CAD design documents and calculation programs can significantly enhance the lifting point selection process. These resources allow engineers to incorporate lifting points directly into technical drawings while considering factors impacting WLL calculations, such as:
Simplified Lifting Point Inspection with RFID Technology
Regular inspection and maintenance of lifting points are essential for safe operation. RUD offers lifting points equipped with RFID transponders. These transponders contain unique identification numbers that a dedicated reader can scan to transmit data to cloud-based software. This technology simplifies inspection recordkeeping and allows for convenient access to vital lifting point information.

Lifting points are fundamental elements within any lifting system. They are the crucial connection between lifting equipment (cranes, hoists) and the load itself, facilitating lifting, rotating, and manoeuvring operations. Common lifting point examples include eyebolts, swivel load rings and pad eyes, which connect to lifting chains using hooks, shackles, or other dedicated connectors. Modern lifting points are engineered to ensure safe load handling and to prevent damage throughout the lifting and transportation process.
Integrating Lifting Points at the Design Stage
With over 140 years of experience, RUD recognises that lifting points are often overlooked during the initial design phase. This can lead to complications and potential safety hazards later in the project. Incorporating lifting points should be prioritised from the outset to prevent such issues. This includes considering lifting requirements throughout the product lifecycle, from production and internal transportation to delivery, installation, assembly, and even potential relocation or decommissioning. Implementing lifting points at each stage minimises risk and promotes smooth operation. During the design phase, collaboration between the engineering, production, logistics, and supply chain management teams ensures proper lifting point integration.
Evolution of Lifting Points: From Simple Eye Bolts to Modern Safety Standards
Over time, lifting point design has evolved to comply with changing regulations and safety requirements. Four decades ago, DIN 580 eyebolts were the most prevalent lifting point option. However, a series of accidents in German underground operations, attributed to eyebolt breakage, necessitated stricter standards. These types of incidents regarding the misuse of collared eyebolts led to the development of modern lifting points, offering significantly higher safety margins against breakage in all directions. As a result, collared eyebolts such as DIN 580 and AS 2317.1 eyebolts are no longer the preferred choice for lifting points.
The Role of Lifting Points in Conjunction with Lifting Equipment
Lifting points play a vital role when working with lifting equipment like cranes, crane trucks, and material-handling machinery. Lifting chains that connect the machine to the load rely on these critical components. In Australia, specific standards for lifting (e.g. AS 4991, AS 3775.2, AS 3776) set the requirements for various lifting gear, prioritising operator safety. This focus on safety emphasises the importance of selecting the most suitable lifting gear for each application.
Types of Lifting Points: Boltable vs. Weldable, Rigid vs. Swivel
Lifting points are generally categorised into two primary types: boltable and weldable. Boltable options are the most common due to their versatility, allowing for easy assembly and disassembly as needed. They are available for standard thread sizes, offering maximum flexibility. Conversely, weldable lifting points are permanently affixed to the load. Their primary advantage is eliminating accidental unscrewing or over-tightening during load rotation or turning. Beyond these classifications, lifting points can also be rigid or swivelling. Rigid variants, such as collared eyebolts or pad eyes, lack adjustability in the pulling direction. Swivel lifting points, on the other hand, offer greater flexibility. They are commonly employed in multi-strand lifting applications, as they can automatically align themselves with the lifting force during load handling.

Advantages of Lifting Points with Swivel and Rotation Capabilities
Lifting points specifically designed for rotating and turning applications offer additional benefits, translating into increased value. These points often integrate ball bearings, enabling a full Working Load Limit (WLL) under rotation. This makes them ideal for scenarios requiring load manipulation during lifting. The ball bearings significantly reduce sudden and unwanted movements during rotation, a crucial safety feature. Achieving smooth, impact-free rotation under load is only possible with these bearings.
Click here for an example of a ball-bearing lifting point - The RUD VWBG Load Ring.
Understanding Working Load Limit (WLL)
WLL is a critical industry term indicating the working load a lifting point can be subject to. Selecting appropriate lifting points necessitates a thorough understanding of their WLLs. Several factors influence a lifting point's WLL, including its attachment method, positioning, load symmetry, and the number of lift points used.

Introduction:
Germany, with 34 million tons of cement production, is Europe's leading cement producer*. When TBA, a renowned concrete supplier needed assistance to lift the roof of a concrete silo used for an infrastructure project, they turned to RUD.
The Challenge:
The project required lifting and placing a roof on top of a silo located near Unterkochen.
The project presented several challenges for the lifting operation:
The Solution:
Due to the heavy lift and the lifting configuration, RUD engineers proposed that a 13mm, 2 x 2-strand ICE 120 chain was ideal for the operation. To maintain the chain's working load limit (WLL) within safe parameters, it was calculated that a minimum length of 6.402 meters was required for low sling angles.
However, there were only 2 x 7-metre 2-strand chains and 2 x 4-metre chains in stock. Instead of postponing the project to another date, we decided to use IH (ICE-H) Connectors to extend the 4-metre chains.
The I-H Connectors are a fast, simple, and cost-effective solution for converting ICE chains into endless configurations. They are compact, easier to manage than conventional chain connectors, and flexible enough to fit the ICE chain.
Once the chains were extended to the necessary length, ICE Star Hooks were attached to the chain ends. Due to their innovative skeletal design, ICE Star Hooks can be used in temperatures from -60°C to 300°C and are up to 25% lighter than Grade 80 hooks of the same WLL.
This solution enabled a safe and secure lift of the silo roof. The roof was lifted to its final height of 35 meters above ground for the final assembly.
Products used in the project:
Conclusion:
This project demonstrates how RUD's innovative lifting solutions, such as the flexible ICE Chains, can solve complex lifting challenges. RUD is the innovator and sets standards for lifting technologies through expertise and flexible solutions to ensure safe and successful operation even in challenging conditions.

Identifying Chain Grades:
Chains are stamped with their grade for easy identification. Grades 80 and 100 use the "(H)" stamp followed by the number (e.g., H8 for Grade 80, H10 for Grade 100). However, Grade 120 employs the "(D)" stamp. It is important to point out here that unlike lifting chains, hoist chains cannot be used for lifting and are stamped with letters to prevent potentially dangerous mix-ups.
Safety Certifications and Testing:
Safety is paramount. Always opt for chains approved by relevant regulatory bodies (e.g., DGUV in Germany). Traceability through batch codes and RFID chips (offered by RUD) is also recommended. Regular inspections and electromagnetic crack tests (every three years) are essential for safety assurance.
Choosing the Right Lifting Chain:
Selecting the right chain hinges on several factors.
RUD will help you with the best chain suspension for lifting based on the following:
Conclusion:
By understanding the types, grades, and applications of lifting chains, you can ensure safe and efficient lifting operations. Remember to prioritise safety by adhering to regulations, conducting proper inspections, and selecting the most suitable chain for your specific needs.

The age-old proverb, "A chain is only as strong as its weakest link," first used in Thomas Reid’s “Essays on the Intellectual Powers of Man” in 1786, perfectly encapsulates the critical role of lifting chains in material handling. This article delves into the world of lifting chains, exploring their types, grades, uses, and essential safety considerations.
What are Lifting Chains?
Lifting chains are crucial connectors between a load and a lifting hook. They are typically secured to a designated lifting point on the load, ensuring safe and secure lifting. Lifting chains form part of chain suspensions, which, along with the chains, include a master link, end components like hooks, connecting or shortening components and balancers if required.
Evolution of Lifting Chains:
Modern lifting chains have significantly improved compared to their predecessors. While past chains suffered from low material strength and cumbersome weight, today's chains offer high strength, durability, and cost-effectiveness, making them the preferred choice for lifting and lashing applications. They also weigh considerably less for the same WLL (Working Load Limit), which is beneficial when lifting heavy loads.
Types of Lifting Equipment:
While wire rope and synthetic slings offer alternative lifting options, they have limitations, particularly in terms of adjustability, susceptibility to sharp edges, and performance under extreme temperatures.
Lifting chains stand out with their:
Choosing the Right Chain Grade:
Several chain grades (Grade 80, 100, 120) exist, each with its own WLL (Working Load Limit). Selecting the appropriate grade is crucial for safety and efficiency.
Grade 80: This has been in existence since 1970. It is very popular in some parts of the world because it offers affordability. However, it has a lower breaking force and weight limitation.
Tip: RUD was the first chain manufacturer, approved for Grade 80 in 1972
Grade 100: It has been in existence for the last 30 years and is popularly used by many operators. It is a step up over Grade 80 and provides a balance between cost and performance.
Tip: RUD launched Grade 100 as VIP (Verwechslungsfrei in Pink) in 2006, and it is still a popular product used in many lifting applications. Click here for more details on the RUD VIP Grade 100.
Grade 120: Grade 120 is the latest and strongest grade, offering lighter weight and higher breaking force than Grade 80. Exclusive to a few manufacturers (including RUD).
Tip: Grade 120 offers a 30% reduction in weight than Grade 80 because it uses less material. It also possesses a 60% higher breaking force than a Grade 80 chain, and it is extremely robust, tough, and resilient to sharp and rough edges.
What this means is that an ICE Grade 120 Lifting or Lashing Chain - no matter the nominal thickness - can replace a Grade 80 chain of a next-higher nominal thickness.
