There are several types of 6mm Din 766 link chains, and each type is designed for specific applications and environments. While all types feature the fundamental strength and durability of the DIN 766 standard, the material and design variations optimize performance for distinct uses. Below are the most common 6 mm DIN 766 link chain types.
However, it’s important to note that in the DIN 766, the link shape for all types must be oval, but the materials and finishes may differ depending on the application.
Galvanized steel chains
A galvanized steel link chain is a popular choice for many owing to its anti-rust properties. The galvanized coating, usually zinc, acts as a barrier against corrosion. This makes galvanized steel chains ideal for outdoor or marine environments. Normally, a 6mm galvanized steel DIN 766 link chain is regularly employed in marine activities, fishing industries, and as mooring lines.
Stainless steel chains
A stainless steel link chain provides superior resistance to rust in contrast to its galvanized counterpart. Normally, stainless steel holds up better in highly corrosive environments. A 6mm stainless steel DIN 766 link chain is regularly used in marine industries, water treatment entities, and places with high humidity or exposure to chemicals.
Proof coil chains
Proof coil chains are designed with added strength to handle heavy loads. They often feature a square or oblong link shape for improved grip and durability. A 6mm proof coil chain is used in heavy lifting, secure cargo and agricultural applications. It’s typically found in mines, construction areas, and warehouses.
High-tensile chains
High tensile chains are made from stronger alloys or additional heat treatment. These chains are thinner but can handle greater loads, providing more strength per weight ratio. A 6mm high tensile chain is normally used where heavy loads are required to be lifted but in situation spaces where the lower chain profile is preferred. Examples include cranes, hoists, and heavy machinery.
Nickel-plated chains
Nickel plating on steel chains helps prevent corrosion, particularly in mildly corrosive environments. Nickel-plated chains hold up to saltwater or acidic environments but may not be as durable as stainless steel. A 6mm nickel-plated chain is used in marine, automotive, and outdoor applications, where rust is needed to be inhibited.
Marine and shipping
DIN 766 chains are commonly used for anchoring and mooring boats and ships. Due to the standard link shape offering secure and stable anchorage grips. The chain's strength is crucial in holding vessels in position against winds and ocean currents. Furthermore, the linked layout helps in smooth interaction with chain handling equipment.
Mining
The DIN 766 link chain is famed for its robustness and reliability in the harsh mining environment. It’s popularly used in hoisting mechanisms to lift heavy loads including ores, machinery, and people. The 6mm chain size provides a balance between strength and ease of handling. These characteristics make it an ideal choice for mining equipment in extreme conditions.
Agriculture
In agriculture, the 6mm chain is used to power and operate various equipment such as conveyers, feed systems, and machinery hooks. Linked chains play a crucial role in transporting heavy items like grains, fodder, and agricultural produce. Their durability ensures they withstand the rigors of farming tasks both indoors and outside.
Construction
Construction industries use this chain size in lifting and rigging equipment, securing heavy materials and machinery, and providing protection for many operations. They drive and support cranes and hoists that lift substantial construction materials. The strength and resilience of the chain make them a reliable choice in the risky construction environment.
Transportation and Logistics
In transportation and logistics, this chain is used to secure cargo in trucks, trailers, and ships. Chains keep the loads stable and prevent any unwanted movements during transportation. Furthermore, they are used in conveyor systems to transport products in warehouses, ensuring efficient operations.
Industrial machinery
The 6mm chains are found in various industrial equipment such as conveyor belts, power transmission systems, and mechanical drives. For example, in machine tools, chains transfer power and motion, enabling the machines to operate effectively. Their toughness ensures they endure continuous heavy usage and wear-and-tear.
Forest industry
In the forestry industry, the 6mm din 766 chain link is used in logging equipment such as winches and cable systems to transport and maneuver large logs and other woods. The chains provide the necessary strength to handle enormous wood weights, ensuring safety and efficiency in hauling operations.
Product specifications and features of the 6mm Din 766 link chain are encapsulated in the details outlined below.
Chain material
Materials include stainless steel, high-tensile steel, and galvanized steel. Each material has its attributes and disadvantages. Stainless steel is excellent for corrosion resistance. High-tensile steel provides extreme strength but at the expense of a less thicker profile. Galvanized steel offers intermediate corrosion resistance at an effective cost.
Environment
Consideration should be given to the environment in which the chain will be used. For outdoor use and marine applications, anti-rust chains like galvanised and stainless steel are ideal choices. If the chain is likely to be exposed to chemicals or salty water, stainless steel should be the material of choice. Galvanized chains are less expensive but offer moderate anti-corrosion protection.
Load requirements
Determine the load the chain is expected to bear. 6mm chains are strong and are ideally suited for medium to heavy-duty applications. Techniques for calculating loads involve factors such as the weight of the load and any dynamic forces acting on it. Seek expert assistance if the required load for the chain is not known.
Chain accessories
Accessories include hooks, eyes, and slings. All should be rated for the same load as the chain and be made from the same materials for uniformity. Accessories should also comply with relevant standards to promote safety.
Compliance
Ensure the chain meets safety standards. The 6mm DIN 766 chain is a widely recognized standard among marine and industrial activities. Certificates to look out for may vary by region but commonly include ISO or AS standards.
Budget considerations
Considering cost is important, especially when the core needs have been addressed. Galvanized chains are often less expensive but may offer lower durability than their stainless steel counterpart. High-tensile chains usually cost more, though they provide higher strength in a lighter profile.
A1: This chain is used in anchoring ships and boats for lifting heavy loads in mining, construction, and engineering for securing items in transport.
A2: The link chain is made from stainless steel, high-tensile steel, and galvanized steel. Each material provides a unique benefit depending on the application. For example, a 6mm stainless steel chain is ideal in highly corrosive environments, while high tensile is ideal in situations that require maximum strength.
A3: The 6mm stainless steel chain has superior resistance to rust and corrosion. This makes it ideal for applications on the water and in chemical processing plants, as well as outdoor areas.
A4: Some of the maintenance tips include regularly inspecting the chain for signs of wear, ensuring it is clean, lubricated, and properly stored, and keeping it covered when not used.
A5: The users should consider the chain’s breaking load and working load limit. These two parameters help determine whether the chain can handle the required load or weight of the item.
