ZJ-A3 Multifunctional Drill Lift

The 3th generation multifunctional drilling tool elevator of our company is designed to separately send the drill collars, drill pipes and casings indexed on the support to the central lifting arm of the platform, which then lifts the drilling tool to the drill floor. This function can safely and effectively lift the tool basket including joints, casing, logging tools and other useful tools to the drill floor.      The multifunctional drilling tool elevator eliminates the need for professional services to grab and drop the drill pipe during the drill pipe running. With its remote control function, the operator can control the equipment on the drill floor or on the ground.
