Calculating the weight capacity of plastic drag chains

Calculating the Weight Capacity of Plastic Drag Chains

Plastic drag chains are an essential component in many industrial and automation applications. They provide a safe and reliable way to protect cables and hoses while also allowing for the smooth and efficient movement of equipment. However, determining the weight capacity of plastic drag chains can be a complex process that requires careful consideration of several factors.

Factors that Affect Weight Capacity

Several factors can impact the weight capacity of a plastic drag chain. These include:

  • Chain Size: The size of the chain is a crucial factor in determining its weight capacity. Larger chains can typically support more weight than smaller chains.
  • Material: The type of plastic used in the chain’s construction can impact its weight capacity. Some materials are stronger than others and can support more weight.
  • Chain Configuration: The way the chain is designed can also impact its weight capacity. Different configurations can distribute weight differently and affect the chain’s overall strength.
  • Length: The length of the chain is also a factor in determining its weight capacity. Longer chains may not be able to support as much weight as shorter chains.

Calculating Weight Capacity

To calculate the weight capacity of a plastic drag chain, you need to consider the above factors and perform some calculations. The following steps can be used as a general guideline:

  1. Determine the weight of the cables and hoses that will be carried by the chain.
  2. Calculate the total length of the chain that will be required.
  3. Select the appropriate chain size and material based on the weight of the cables and hoses and the length of the chain.
  4. Determine the chain configuration that will be used.
  5. Use the manufacturer’s weight capacity charts to determine the maximum weight that can be supported by the selected chain.

Plastic Drag Chain in Use

It is essential to note that these calculations are only a guideline. It is always best to consult with the manufacturer to ensure that the selected chain is appropriate for the application.


Calculating the weight capacity of plastic drag chains is a critical step in ensuring the safe and efficient operation of industrial and automation equipment. By considering factors such as chain size, material, configuration, and length, it is possible to determine a chain’s weight capacity and select the appropriate chain for the application.
