Turnbuckles are part of almost all tension-related construction and rigging applications. Also known as bottlescrews, this rigging hardware is used to tighten and adjust cables, ropes, and wires.
Most turnbuckles consist of two end fittings- eye bolts or hooks- connected by a threaded metal bar or rod. The threaded rod helps adjust the length of the hardware, which changes the tension of the rope or cable it was attached to.
As with any rigging hardware, you must use turnbuckles correctly to ensure safe and effective operations. Because turnbuckles often secure heavy loads, improper usage can result in accidents, injuries, or property damage.
Additionally, using turnbuckles correctly keeps you compliant with industry standards and prevents potential penalties/legal issues.
In this post, we’ll discuss the correct ways to operate heavy-duty turnbuckles for your rigging projects. Let’s dive in!
How to Choose Heavy-Duty Turnbuckles
The first step in using turnbuckles is to choose the right type of hardware for the job. Typically, turnbuckles fall into seven categories based on their end fittings.
- Hook-and-Eye
- Jaw-and-Jaw
- Hook-and-Hook
- Eye-and-Eye
- Stub-End
- Toggle-and Swage
- Clevis-and-Clevis
Since turnbuckles often act as connectors, it’s crucial to pick them carefully. The last thing you’d want is an on-site accident because you didn’t use the right hardware.
A few factors to consider when choosing turnbuckles are:
- Material: The material of the turnbuckle hardware must be compatible with the ropes, chains, and cables in use. For example, stainless steel ropes/cables require stainless steel turnbuckles.
- End Fittings: Check out the fittings on your rope ends to decide what type of heavy-duty turnbuckles you’ll need. Ropes with hook ends must be paired with hook-and-eye turnbuckles, and so on.
- Environment: Consider where the turnbuckle hardware will be used. Some projects may call for corrosion and heat-resistant turnbuckles.
- Load Capacity: The turnbuckle’s load limit should be equal to or greater than the weight of the load.
A Step-by-Step Guide to Proper Turnbuckle Usage
Most turnbuckles are designed to operate in a specific way. So, when they aren’t used correctly, they won’t work as intended. For example, overtightening the turnbuckle hardware may cause it to fail, leading to load damage.
Fortunately, turnbuckle usage isn’t rocket science. There are a few steps to follow in this regard.
Step – 1. Determine the Correct Size and Type
First, carefully consider the turnbuckle hardware’s load, fit, and corrosion resistance capacities. Picking a turnbuckle that’s too large or too small for the load can make it difficult to adjust and tension it. Also, if you’re using the hardware in a particularly hazardous environment, check whether it can withstand the conditions without giving out.
Step – 2. Prepare the Location for the Turnbuckle Installation
Before installing the heavy-duty turnbuckles, examine if the components are strong enough to support the load. Also, leave enough space in between to allow for proper tensioning.
Step – 3. Install and Tighten the Turnbuckle
Now for the fun part: here’s how to install turnbuckle hardware hassle-free.
- Unscrew the end-fittings from the body until fully extended.
- Connect them to either side of the components at the desired securement point. For a jaw-end fitting, place the securement point between the clevis ears, thread the bolt through, and screw it shut.
- Rotate the turnbuckle to move the ends closer until you reach the desired tension.
- Tighten the nuts if in use.
A quick word of advice. Always follow the manufacturer’s instructions for heavy-duty turnbuckles. And, as with all rigging equipment, remember to keep the turnbuckle’s Working Load Limit (WLL) in mind.
Turnbuckle Usage: Best Practices
Risk management is a big part of rigging and lifting. It’s crucial to follow best practices when using turnbuckles to mitigate potential hazards, protect workers, and ensure safe/compliant operations. A few turnbuckle usage best practices to follow include:
- Check the turnbuckle regularly for wear and tear. Make sure there are no visible signs of damage. In case you spot any disrepair, replace the heavy-duty turnbuckles immediately.
- Always lubricate your turnbuckle hardware to reduce friction, prevent corrosion, and minimize noise during operation.
- Use turnbuckle covers to protect your hardware against the elements when not in use.
When it comes to rigging equipment, a little proactive maintenance can go a long way. Talk to an industrial hardware supplier if you don’t know how to take care of your turnbuckle hardware.
Safety Tips When Using Turnbuckles
Safe turnbuckle usage can help prevent untoward accidents on your project site. After all, you don’t want your people or property to come in harm’s way. To that end, we have compiled a few safety tips to follow.
- Always wear appropriate personal protection equipment, such as gloves and safety glasses, when handling turnbuckles.
- Only use heavy-duty turnbuckles that are rated for the load they will bear.
- Never overload the turnbuckle hardware.
- Inspect the turnbuckles before each use.
