The Roto Link is a one piece, stainless steel, universal link designed to connect loose ends of Lock Link Chain when used in conjunction with our Roto Hammer Chain Wheel Actuators. This prevents the hassle of cutting and twisting chain to close the loop. Simple installation can be accomplished with either vise-grips or pliers used to close the open ends around the next link of chain. Roto Links are made of T302 Annealed Stainless Steel for its non-corrosive properties.
Provisions must be made to prevent the HANDWHEEL RETAINING NUT FROM BACKING OFF whenever a chain wheel is installed. To insure safe operations, Roto Hammer recommends that thorough inspection of all chain operated valves be performed as a routine part of the user’s Safety/Maintenance Schedule. Set screws and other threaded fasteners MUST be secure and tight.
In addition, it is strongly recommended that an appropriately sized Roto Hammer RCK Safety Cable Kit (optional) be installed on every overhead chain wheel operated valve.
