Pneumatic spider
Safe and reliable: one elevator & one slip can be used for tripping operation, and there is no need to change double elevators back and forth, which fundamentally avoids the occurrence of single lifting ring accident.
Fast and convenient: it is not necessary for on-site operators to manually push and pull elevators or lift and place slips, so as to save pipe string time such as tripping or casing running.
Strong applicability: the pneumatic spider is external, especially suitable for various well conditions such as well deviation.
Easy to operate: the spider can be opened and the pipe string can be clamped only by operating the directional valve.
Mud hanging function: the blowing function is added to ensure the cleanness of the wellhead during tripping out.
