Highlights
Features

Safe

Innovative mechanical locking mechanism — robust and durable. Redundant hydraulic locking and feedback design for safety and reliability.

Wide Pipe Range

By changing adapters, it covers pipe from 2-7/8" to 7-1/4".

Easy to Maintain

The door mechanism is easy to service; adapters can be changed quickly; and in the event of an elevator fault, the load can be released manually and rapidly.

High Reliability

Extra-large opening/closing torque keeps the elevator operating smoothly even with winter icing and mud contamination.

Fewer Oil Passages Occupied

Only two top drive rotary oil passages are used for automatic closing, driller-operated opening, equipment interlock and mechanism tilting. Fitting to an older rig requires no top drive modification.

Intelligent Interlock

Linked and interlocked with JJC's Iron Roughneck machine-vision module for one-touch fully automatic operation.
