Elevator is used to hold drill string or casing and tubing for tripping during drilling, completion or workover operations.
Elevator is forged or cast with high-grade alloy steel, and receives heat treatment. The main parts of elevator have been inspected by nondestructive test. The elevator is simple and sturdy, safe and easy to operate and is featured with high abrasive resistance and light weight.
Model CD side open double latches elevator is suitable for 90-degree shouldered drill pipe, casing and tubing.
Model CDZ side open latch dog elevator is suitable for 18-dregee shouldered drill pipe.
DD center latch 90-degree shouldered elevator is suitable for 90-degree shouldered drill pipe and tubing.
DDZ center latch elevator is suitable for 18-degree shouldered drill pipe.
Sucker rod elevator is used to hoist the sucker rod or tubing for tripping during workover operations.

Rod elevator
Elevator link
Elevator link is used to link up hook and elevator to hoist drill string, casing and tubing during tripping in drilling or completion operation.
Model DH weldless link is one-piece forged special alloy steel with high strength and toughness. They are suitable for deep well drilling operation. Model SH link is made of high-grade alloy steel with good mechanical properties, which is suitable for shallow well drilling operation. Both types of elevator links are well heat-treated and special surface treated, and receive strict nondestructive inspection. They have the features of abrasion resistance, long service life and safe and easy operation.
Elevator links are API monogrammed.
