Bolt Module – Key Rotation to Linear Motion


The Bolt Module offers mechanical blockage to prevent motion. 





     “How Robust is the Fortress Solution?” 





Power Interlocking ⚡


“Interlocking which directly interrupts the energy supply to the machine actuators or disconnects moving parts from the machine actuators”.



Power interlocking is often overlooked as a means of reducing risk as engineers may focus on gate switches, or presence sensing, but it can offer a cost effective and safe solution in many cases.





Power Interlocking with Mechanical Bolt Module














Prevention of Valve Rotation



In the images below, the bolt module has been used to mechanically prevent the valve (in red) from rotating (returning pneumatic power to this system) when the key has been removed.













Prevent Return of Electrical Energy with the Bolt Module



The Bolt Module can be used to prevent cam rotation. In the examples below, the cam is connected to the source of electrical power supply. When the key is inserted, the bolt is retracted from the inset profile enabling the cam to rotate. Whilst the cam is rotated, the key cannot be freed from the bolt module, ensuring isolation is performed before key release.

How to Design Your Bolt Modules?



1. Material


Modules come in two different varieties, robust metal alloy (BM) or Full Stainless Steel (BMS).



BM – Robust Metal Alloy   |   BMS – Full Stainless Steel





2. Environment


If operating in extreme conditions such as cold temperatures, saltwater exposure, external ‘weathered’ locations, or wet & humid environments including where wash down is performed, the stainless steel (BMS) option is recommended.



Protect your Locks from dust and particulate ingress. Padlock-able dustcovers are also available for this product and can receive up to two padlocks per lock.
