Key interlock system. What is a trapped key interlock system? The use of interlock systems is a proven method for predominantly mechanical securing of machines and processes. . Trapped-key interlocking utilizes locks and keys for sequential control of equipment and machinery to ensure safe operation. Mar 18, 2024 · Fortress specialises in interlocking and has expertise in designing and providing trapped key systems to meet the requirements of each application. The key interlock is interfaced to the equipment operating mechanism (handle, linkage, rotating cam, or similar) in such a way as to facilitate the locking and key release requirements. Jul 3, 2018 · Trapped key interlocking is a mechanical approach to interlocking power or machine guards that offers some significant advantages. Interlock systems are based on the release and locking of uniquely coded keys in a predetermined sequence. Auxiliary switches, solenoid devices, and an array of ancillary options are available to fully integrate our interlock system with process control equipment. It is attached with one-way security screws to discourage casual removal, which would defeat the interlock scheme. Trapped Key Interlock Switches Trapped key systems use a series of mechanical locks and key (s) to control the access of gates or doors to running equipment or machines for safety. In particular, Fortress has a range of mechanical trapped key interlocks, mGard. Key interlocks avoid the limitations of electrical interlocking and the restrictions of mechanical interlocking by making use of easily portable keys, carried in sequence from one interlock to the next. Rotary key or push-pull style tongue sets include a main station and multiple lock/key modules; solenoid locking versions are also available. The use of keys imparts a human factor and provides physical evidence of equipment status.
