Collar Load Support (CLS)™ System
The Collar Load Support (CLS™) system is the industry’s only true non-marking tubular handling system.
When coupled with Expro's TRS FLUID GRIP® system, this patented procedure provides the only non-marking/zero mechanical damage system in the industry for make-up and handling of completion tubulars.
For completions which include control and injection lines running downhole, Expro’s TRS COBRA® Control Line Manipulator Arm can be coupled to the CLS™ system.

Features and Benefits
- Allows for both surface-mount and flush-mount shock table configurations, dependent on rotary size
- Accommodates multiple control lines or large umbilicals typically encountered on high-tech completions
- Eliminates the potential for corrosion cracking as a result of stress concentrations induced by conventional handling equipment as the CLS™ system imparts no penetration impressions to the tubular
- Allows the running of threaded and coupled tubulars without inflicting damaging die penetration marks caused by typical slip-type elevators or spiders
- Minimizes the risk of slip crush or iron transfer as the tubular is supported by the load face, and not penetration, to avoid the slippage issues prevalent on certain alloys with conventional inserts
- Reduces the potential for shock loading of the coupling during load transfer by the elastic compliance of the built-in shock table
- The shock table provides gentle deceleration of the joint and string during load transfer operations between the load transfer sleeve (LTS) and landing spear
