Gripper and attachment chains

Gripper and Attachment Chains for Packaging and Production Lines

Efficient and reliable transport is essential in every packaging or production line. Whether it’s about accurately positioning goods or firmly holding packaging material in place – gripper and attachment chains play a crucial role. At Donghua, we offer a wide range of chain solutions tailored to various applications and industries, including food processing, pharmaceuticals, and logistics. Our chains are designed to minimize downtime, simplify maintenance, and maximize performance. Discover how our high-quality gripper and attachment chains can help optimize your processes.

What are gripper and attachment chains?

Gripper chains are specially designed to firmly hold packaging film. This allows products such as glass bottles, food packaging, and small machine parts to be easily packed. The chains are widely used in packaging lines, for example, for packaging with thin plastic films.
Attachment chains are chains with attachments that are available in various types and sizes. These attachments are a fixed part of the chain and are used for different applications, such as moving products or precisely positioning goods for the next step in the production line. Additionally, attachment chains can perform extra tasks, such as rotating, stacking, or precisely aligning products, making them a versatile solution for complex transport systems.

The role of gripper and attachment chains in packaging and production lines

Gripper and attachment chains together form a reliable solution in industries such as food processing and logistics. The robust design of these chains is developed to reduce downtime, allowing processes to run more smoothly and minimizing interruptions. This is crucial in industries where high efficiency and reliability are essential.
Additionally, these chains are designed to be easily adapted to specific applications. This ensures that conveyor belts not only operate smoothly and efficiently but also contribute to lower maintenance costs and longer system lifespan.

How to choose the right gripper or attachment chain?

Choosing the right gripper or attachment chain is important to optimize your transport performance. The following steps can help you determine which chain best fits your application.

Function of the chain

Start by clearly identifying what function the chain must perform. Should it hold products, position them, or support them during transport? It is important to understand what is needed so you can choose a chain that meets those requirements.

Consider the working environment

Examine the conditions in which the chain will operate. Will it be exposed to moisture, high temperatures, dirt, or chemicals? For humid environments, a chain with special coatings or stainless steel materials is the most suitable choice.

Assess the load on the chain

It is important to understand how much weight the chain must carry. For example, if you need to move heavy goods, you need a robust chain specifically designed to safely bear that weight. On the other hand, if the task is less demanding, a chain with a smaller pitch may be more suitable.

How to choose the right accessories?

Accessories such as grippers, attachments, or extended pins play an important role in how the chain functions. They ensure that the chain can hold, push, or transport products. Therefore, it is essential that the chain and accessories fit together perfectly so that they function as one cohesive system and deliver optimal performance within the transport system. Our experts are happy to help you choose the right accessories.
In addition, precision is a crucial aspect in selecting accessories. Chains can be matched and labeled to ensure they have exactly the right length and specifications for the application. By matching and labeling chains with precise length variations, consistent operation within the transport system is ensured.

Durability and maintenance

A chain that lasts longer saves costs in the long term. Choose a model that is not only robust but also meets your maintenance preferences. Regular inspection and proper maintenance extend the lifespan of the chain and reduce the risk of failures. View our oil and maintenance brochure for specific recommendations on the optimal maintenance of your chain.

Practical tips for installation and maintenance

To ensure that gripper and attachment chains continue to perform well, proper installation and regular lubrication are important. The tension of the chain must be just right. A chain that is too tight can lead to high wear, while a loose chain can skip or derail. Also check that the chain fits properly with the sprockets and other components, so that all parts work together smoothly. Lubrication is a key factor. It reduces friction and extends the lifespan of the chain. If you work in an environment with a lot of dust, dirt, or chemicals, it is essential to choose the right chain for these environmental factors. In use, it is important to regularly clean, re-lubricate, and check the chain for elongation. These steps keep your chain reliable and help prevent problems.
