Standard Metal Shackles vs. HMPE Soft Shackles:
Soft shackles have been gaining popularity, but why?
When it comes to rigging for lifting and recovery, the choice between traditional metal shackles and modern HMPE (High Modulus Polyethylene) "soft shackles" can have a significant impact on efficiency, safety, and ease of use. While metal shackles have been the trusted solution for decades, soft shackles provide a lightweight and versatile alternative that is gaining popularity across various industries. Let’s explore some of the key differences between these two types of shackles.
Key Differences Between Metal & Soft Shackles
Weight Savings
One of the most noticeable differences between metal shackles and soft shackles is the weight. Traditional metal shackles, typically made from forged steel, are durable but heavy, adding unnecessary weight to lifting and recovery operations. In contrast, HPME soft shackles are significantly lighter—often weighing up to 80% less than their metal counterparts. This reduction in weight makes handling and transport easier while also minimizing the strain on equipment and personnel.
For example: A 1-3/4" bolt type shackle with a WLL of 88,000 lbs weighs approximately 33.8 lbs.
The comparable soft shackle would be 1-1/2" with a WLL of 88,400 lbs. and weigh approximately 2.5 lbs.
Ease of Use
Soft shackles are designed for quick and simple use. Unlike metal shackles that sometimes require tools or pins to secure and remove, soft shackles can be fastened by simply looping them around an attachment point and pulling them tight. This ease of use can save valuable time in demanding conditions such as vehicle recovery, marine applications, and industrial lifting scenarios.
Not to mention, soft shackles are flexible, allowing them to conform to irregular shapes or surfaces where metal shackles might not fit. This adaptability makes them especially useful in off-road recovery, where attachment points may be inconsistent or difficult to get access to.
Little to No Stored Energy
A crucial safety advantage of soft shackles is their lack of stored kinetic energy. When a metal shackle fails under load, it can release dangerous amounts of energy, turning it into a high-speed projectile that poses a significant injury risk to surrounding workers and equipment. Soft shackles, on the other hand, do not store the same amount of energy and are less likely to cause injury in the event of a catastrophic failure.
Applications of Soft Shackles in Recovery and Lifting
Vehicle Recovery: Off-road enthusiasts, towing professionals, and first responders often turn to soft shackles for their strength and ease of use in vehicle recovery situations. Their lightweight design allows for quick deployment, and their flexibility ensures a secure connection to recovery points without damaging painted or delicate surfaces.
Lifting Operations: In lifting applications, soft shackles provide a lighter alternative to metal shackles by reducing weight and minimizing the risk of damage to lifted loads. Their non-metallic construction also eliminates concerns about sparking in flammable or explosive environments.
Enhance Safety & Efficiency with Soft Shackles
While standard metal shackles remain a staple in many lifting and rigging applications, soft shackles offer distinct advantages in terms of weight savings, ease of use, and safety. Whether you’re working in vehicle recovery, industrial lifting, or marine environments, incorporating soft shackles into your rigging toolkit can help enhance efficiency while improving overall safety. If you're looking to upgrade your equipment with soft shackles, consider how their benefits align with your operational needs.
