Collar Load Support

The Collar Load Support (CLS™) system is the industry’s only true non-marking tubular handling system.

Key Benefits and Features:

  • Flush mounted into rotary to reduce working height
  • Accommodates multiple control lines typically encountered on today’s high-tech completions
  • Eliminates the potential for corrosion cracking as a result of stress concentrations induced by conventional handling equipment since the CLS™ impacts no penetration impressions into 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 CLS™ enables the tubular to be supported by the load face, and not by penetration, avoiding 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 from 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

Collar Load Support (CLS) System

When coupled with Frank’s FLUID GRIP® system, this patented procedure provides the only non-marking/zero mechanical damage system in the industry for make-up and handling completion tubulars.

For completions which include control and injection lines running downhole, Frank’s Cobra™ Control Line Manipulator Arm can be coupled with Frank’s CLS system.
