Center Latch Elevator

Air-Operated Center Latch Elevator

The center latch elevator is utilized to lift casing, tubing, drill collar and drill pipe in workover and drilling operations. It undergoes a series of stringent tests before leaving our factory, like radiographic inspection, nondestructive test, type test and delivery inspection, to make sure that our center latch elevator's technical performance is compliant with API Spec 8C.

Feature
1. The square shoulder elevator is scientifically structured to offer safe and reliable performance with simple operation, and it is manufactured from ANSI/ASTM A487 high-strength steel through leading-edge heat treatment and other processing procedures.

2. Our center latch tubing elevator provides normal performance from -20℃ to +70℃, and it is exceptionally suitable to handle 90 degree taper shoulder drill pipe whose diameter is within 23/8-51/2 inches.
