Special Design for Tapered Mill - Hydro-Mechanical Drilling Jar Type JYQ – Gaofeng

Hydro-Mechanical Drilling Jar Type JYQ

Model JYQ Drilling Jar can integrate the mechanical and hydraulic. The up jarring can be acted by hydraulic  as to realize the stepless control of up jarring tonnage. The lock mechanism designed specially can avoid the mistaken jarring of up. The down jarring can be acted mechanically. It can adopt the new special material for higher property and safety. It can be used for directional hole, deep hole and so on.
