Project Description
TRIANGLE TYPE TOWING CHOCK
Triangle Type Towing Chock is heavy‑duty closed‑type marine deck hardware, mounted on ship bulwark for towing and mooring operations. Its unique triangular closed‑frame structure prevents rope jumping‑out, delivers high structural rigidity under heavy towing loads. We can supply the chock with optional stainless‑steel wear plate lining for enhanced anti‑corrosion and abrasion resistance. Widely adopted for cargo ships, tugboats, work vessels and offshore support units.
