Texas-Based Trinity Sling Provides Lifting Equipment and Services Both Nationally and Internationally



Trinity Sling was founded more than 40 years ago on a solid foundation of core rigging. Our marketplace has changed, and so have we. Trinity Sling’s second generation of leadership uses new knowledge and technology to evolve with industry changes.

Our experience is our strength, but we have grown. We offer many proven lifting solutions, such as rope, chain, hardware, below-the-hook synthetics and other materials. Our cable railing is flexible for many job sizes, from major stadiums to residential or commercial decking. Name brands and products of high quality are just the beginning, though. More important than what we use is how we help our customers exceed their objectives.



We constantly seek new applications and markets for our products and services. Our owner patented a pioneering engineered restraint system called the Gangline™ that reduces downtime for oilfield and hydraulic fracturing service companies in rig-up, rig-down, or mid-stream rigging changes. This new restraint system also makes the whole restraint process more secure and less cumbersome than before.

Innovating and looking for new ways to protect our customers’ people, property, and profits is also a high priority for our team here at Trinity Sling. Recently, we partnered with an RFID chip company to make inventory tracking and parts recertification a breeze for our customers.

We are confident in our direction, and we welcome the opportunity to serve the modern manufacturing industry as a full-service lifting, moving, and securing solutions provider both in the Dallas/Fort Worth Metroplex and around the world.




“Over the past two years we have field tested several of the advertised ‘Restraint Systems’ and found them to be sub-standard for a host of reasons. We have seen pump iron restraints evolve from the ‘whip checks’ that most companies started with all the way to the Kevlar endless loops. All of the previous systems provided less than desirable results when applied in the field, either with actual performance or ease of application and service once applied. Working with the Trinity Sling Gangline™ Restraint System has proven most valuable and has mitigated the deficiencies found with other systems we have tried. We set forth several standards that we wanted to meet and we have found those with this system. Starting with the ease of application and continuing all the way to the actual performance we have documented numerous advantages, some not advertised. The ability to remove the system from a middle of the line connection, to make corrections to the pump iron without having to remove the entire system has saved numerous hours of field time allowing us to provide better service to our customers. The simplicity of the system allows field personnel to receive minimal training to apply and maintain the system.By far one of the biggest advantages is the customer support we have received from you and the staff at Trinity Sling. Not to mention this is the one of the first systems that was designed from the start as a restraint system, not something that was retrofitted or simply re-tagged to be a restraint system. We all know how hard this can be with the absence of a national standard for restraint systems and the understanding of force vs. pressure. You are definitely the pioneers in dedicated restraint systems, and I base that opinion on 15 years of pressure pumping experience along with 7 years in the HSE field.”
