MODIFIED ROTARY SLIPS FOR POWER SLIP LIFTER: 

Standard/ Regular Rotary Slips are not suitable for Power Slip Lifter. Rotary Slips need to be modified to expand its opening so that it can pass Tool Joints of Drill Pipes through it at the time of drilling operation.  

JOT will provide modified Rotary Slips (If ordered along with PSL) or will provide drawings for modifications so that it can be done at your site.
