Grade 70 chains, known for their robustness and exceptional strength, stand as a cornerstone in various industries, particularly in transportation and load securing. This article delves into the specifics of Grade 70 chain strength, elucidating its properties, applications, and the pivotal role it plays in ensuring the safe transport of heavy loads.

Unveiling the Strength of Grade 70 Chains
Understanding Grade 70 Chains:
High Tensile Strength:

Grade 70 chains, also known as transport chains, are recognized for their high tensile strength.
They are engineered to withstand heavy loads and provide a reliable means of load securement.
Gold Chromate Finish:

Grade 70 chains are easily identifiable by their gold chromate finish, which enhances their corrosion resistance.
This finish not only provides a distinct appearance but also contributes to the chain’s longevity.

Strength Specifications:

Breaking Strength:

Grade 70 chains typically have a breaking strength of several tons, making them suitable for demanding applications.
The breaking strength is a crucial indicator of a chain’s ability to handle substantial loads.
Working Load Limit (WLL):

The working load limit specifies the maximum load a Grade 70 chain is designed to handle safely.

Rigorous testing ensures that the chain meets or exceeds specified safety standards.

Applications of Grade 70 Chains

  • 1. Transportation Industry:
    Grade 70 chains play a pivotal role in securing heavy loads during transportation.
    Widely used by truckers and haulers for their strength and durability.
  • 2. Towing Applications:
    Due to their high strength, Grade 70 chains are commonly employed in towing operations.
    They provide a reliable means of connecting towing vehicles to the load.
  • 3. Construction and Rigging:
    Grade 70 chains are utilized in the construction industry for securing building materials and equipment.
    They are also employed in rigging applications where strength and reliability are paramount.

Choosing Grade 70 Chains Wisely

Assessing Load Requirements:

Evaluate the weight and nature of the load to determine the appropriate chain strength.
Compliance with Standards:

Ensure that Grade 70 chains used comply with industry standards and regulations.

Regular Inspection:

Periodic inspection of Grade 70 chains is crucial to identify any signs of wear or damage.
By mastering the strength of Grade 70 chains and understanding their applications, industries can enhance safety, reliability, and efficiency in the transport and securement of heavy loads.
