<p>A power-actuated pipe coupler for quickly, securely, and releasably coupling together two flanged conduits, such as a marine loading arm and an oil tanker's manifold, in fluid-tight coaxial relationship. The coupler includes a plurality of clamp assemblies mounted on and spaced circumferentially around the end flange of the arm, and power supplied by a hydraulic, pneumatic or electric motor is transmitted through a belt, chain or gear drive unit, a screw shaft, and a toggle link assembly to open and close hook-shaped clamp arms about the manifold flange.</p> |
