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.

Highlights

High Efficiency

Patented structural design and greater opening and closing torque allow for smooth opening and closing of the push-hold type piping system, significantly increase efficiency, even in frozen winter or under mud pollution conditions.

Enhanced Safety

Patented fail-safe locking mechanism ensures operation safety. Reliable door opening and closing signal feedback ensures automatic inter-locking to provide control safety. In addition, it can be configured to carry signal feedback to further improve the performance of safe operation.

Convenience

Only two oil paths through the rotating head required to all in-service top drive, least modification of the top drive equipment; The enlarged lifting ring space design makes it suitable for various models and types of lifting rings; The long and short types of the flip mechanism options, better for

Easy Maintenance

The opening and closing drive mechanism is easy to maintain and the hydraulic manifold assembly is easy to disassemble. The bushings can be replaced quickly. Modular function design, convenient configuration options, easy maintenance.

Minimum Oil Passages Required

Only needs 2 hydraulic oil paths from top drive for all functions, including door closing, door opening, rotating mechanism, and safety interlocking, etc. No modification needed on in-service top drive rotating head,which can significantly save the customer cost.

Smart Interlock

With JJC Smart Wrench AI package, “one-button” operation may be achieved.
