automated for drill pipe Hydraulic Elevator

JJC hydraulic elevator adopts innovative fail-safe door opening, closing and interlock mechanisms, more reasonable structure, higher torque of door opening and closing, higher reliability, to achieve fast clamping, loading and releasing of drilling pipes. Only need 2 hydraulic oil paths from top drive for all functions, including door opening, door closing, and rotating mechanism, and provides reliable elevator door opening and closing signal feedback, suitable for all models of existing top drives. No modification needed on old top drive rotating head. In addition, the configuration of elevator loading signal feedback is optional.
