Weldless links (single-arm)

It feature an integrated weld-free structure, boosting structural integrity by eliminating weak points from welded joints. Designed to mount traveling blocks/top drives above and elevators below, these compact links perform well in space-constrained wellheads, with load ratings optimized for standard tubing/casing lifting—making them a reliable pick for routine workover and top drive-equipped rigs.

Perfection links (dual-arm)

It is built for heavy-duty hoisting, with multi-grade load ratings (e.g., 30–150 short tons) to match drill collar elevators and large-diameter tubular lifting. Mounting traveling blocks/drill collar elevators above and elevators below, these links offer customizable length options for specific rig setups, delivering robust performance in cluster wells, deep wells, and high-load offshore operations.
