Lug & Clamp Design Details

Product News

The lug and clamp design on the Lee Posi Lock is inspired by the API 16A design of connections used on Subsea risers. This connection has been proven through decades of trial to be a dependable means of coupling equipment in high-pressure situations. The design is also simple and contains a minimal amount of moving pieces which simply means less maintenance and less chance of parts failing. The clamp can be opened or closed within 30 seconds which allows for the o-ring to be seated smoothly. Additional safety considerations are in place, including a brake on the hydraulic motor which locks the worm gear from rotating while in closed position, as well as a twin screw efficiency low enough to self-lock and not backdrive. Manual operation is available if hydraulics should fail.
