Interlocks can be used in many process or procedural systems within Ports involving the transmission of electricity, including crane movement, Ship to Shore power, and local substations or backup generators.

 

KIRK® type DM locks with chain that are attached to medium voltage connectors located in quayside vaults ensure proper procedure is followed when connecting shore to ship power. These MV connectors feed the ships with crucial electricity, enabling diesel on-ship generators to be switched off whilst in dock, also known as cold ironing. The upstream breakers feeding the vaults are equipped with KIRK® type F locks, which are keyed to correspond to the interlocks on the vault cover or connectors. This ensures power is disconnected before the connectors can be engaged or disengaged, prohibiting operations under load.  For more information on this application, click here to view the application data sheet.

We recommend our electropolished 316 stainless steel HD series for use in port applications, as the environments tend to be more harsh and interlocks are more often exposed to the outdoor elements. With an excellent corrosion resistance and a heavy-duty build, our HD series is designed to withstand the toughest of conditions.

Further applications of safety interlocks in ports around the world are electrified Ship to Shore Cranes, Rubber Tire Gantry Cranes, Rail Mounted Gantry Cranes, and Automatic Stacking Cranes. These trapped key interlock systems safeguard the safety of operators and the machinery when working on the equipment. Typical KIRK® products for this application are the type D, the type FL, and the base-mounted type B interlock. Transfer blocks and panels enable key exchanges between operation sequences.
