How to Calculate the Weight Capacity Required for Plastic Drag Chains

Plastic Drag Chain

Introduction

Plastic drag chains are widely used in various industries to protect and organize cables and hoses in moving applications. However, choosing the right weight capacity for plastic drag chains can be a challenging task, as it requires considering various factors such as cable weight, bending radius, and travel distance. In this article, we will discuss how to calculate the weight capacity required for plastic drag chains.

Factors to Consider

The weight capacity of plastic drag chains depends on several factors, including:

  • Cable weight
  • Bending radius
  • Travel distance
  • Operating speed
  • Environmental conditions

Cable Weight

The weight of the cables or hoses that will be contained within the drag chain is a critical factor in determining the weight capacity required. You can determine the weight of the cable by multiplying the length of the cable by its weight per foot.

Bending Radius

The bending radius of the cables is another essential factor in determining the weight capacity required. The bending radius is calculated by dividing the minimum bend radius of the cable by the number of cables in the bundle. The larger the bending radius, the higher the weight capacity required of the drag chain.

Travel Distance

The travel distance of the cables is also a critical factor in determining the weight capacity required. The longer the travel distance, the greater the weight capacity required of the drag chain.

Operating Speed

The operating speed of the drag chain is another factor to consider when calculating the weight capacity. Higher speeds require higher weight capacities to ensure safety and reliability.

Environmental Conditions

The environmental conditions in which the drag chain will be used can also affect the weight capacity required. For example, harsher environments such as outdoor applications or corrosive environments may require a higher weight capacity.

Calculating Weight Capacity

To calculate the weight capacity required for a plastic drag chain, you can use the following formula:

Weight Capacity = Cable Weight + (Bending Radius x Number of Cables x 2) + Travel Distance x Cable Weight x Operating Speed x Environmental Factor

The environmental factor takes into account any harsh conditions and can be calculated as follows:

Environmental Factor = 1.0 for normal conditions

Environmental Factor = 1.2 for harsh conditions

For example, suppose you have a cable that weighs 0.15 lbs/ft, a bending radius of 3 inches, a travel distance of 10 feet, an operating speed of 5 ft/s, and harsh environmental conditions. In that case, the weight capacity required would be:

Weight Capacity = 0.15 + (3/1 x 2) + (10 x 0.15 x 5 x 1.2) = 10.8 lbs

Conclusion

Calculating the weight capacity required for plastic drag chains is crucial to ensure safety and reliability in moving applications. By considering the factors mentioned above and using the formula provided, you can determine the weight capacity required for your specific application.
