Plastic Pellet Application
Fortress’ Alfred range keeps people safe when accessing complex machinery, specifically ones which create large quantities of dust particles like the example below. Dust particles create a hazardous environment which is prone to explosions. The Alfred range is designed and certified to be used in explosive atmospheres / hazardous locations and with additional IP69 certificate, the sealing protection makes Alfred perfect for any heavy duty harsh dusty environment.
In zone 2/22 our solenoid interlock releases access keys to the mechanical only units on the hatches. The hatches are controlled by mechanical only interlocks in zone 0/20. While the keys are being used to access the three hatches on the machine, the safety circuits in the solenoid unit cannot be closed, so the machine remains in a safe state. Once all keys are returned to the solenoid unit the machine will return to normal state.

Outside the Area
Machine controls are placed outside the explosive atmosphere. Learn more about Fortress machine controls options, hardwired or ethernet here.
Solenoid Alfred Unit
Our solenoid unit releases the keys to the hatches when the machine is in a safe state. It can be used in Zone 1/21 or Division 2.
Hatch Mechanical Locks
All our mechanical units can be used in Zone 0/20 or Division 1 as they are entirely mechanical units (made of stainless steel) with no electrical components. These units can only be opened with the access keys provided by the solenoid unit once the machine is made safe.

Enclosed Spaces & Restricted Access In Steel Production
When colleagues perform tasks in enclosed spaces, measures are needed to prevent machine restart – but what solutions are available?
Automotive Manufacture Safety – Body Shop
Long production lines operating alongside heavy industrial machinery, lots of entrances and frequent access can make gate interlock installation inefficient and costly.
Automated Crane Systems in Steel Manufacture
Automated crane systems create dangerous hazards to individuals operating in the vicinity; learn which risk reduction measures can be applied
Construction Materials – Brick Forming
In large brick forming facilities, parallel conveyors can be used to transport bricks between the hazardous forming process to the packaging and palletiser areas.
Construction Materials – Clay Extrusion Silo Safety- Whole Body Access & The Escape Release
Designing a safeguarding solution for whole body access with an escape release. When are Proactive Inhibit Functions unnecessary for safe access? Learn more about the Fortress Solution in this article.
Metal Shearing – Sheet Metal Material Removal
Steel Shearing in Sheet Metal Production can be highly hazardous. Safe efficient access to machinery is critical to maximise productivity and minimise downtime.
Construction Materials – Instantaneous Access to a Brick Setter
Instant access to machinery can be achieved with a monitoring only interlock. When whole body access is also being performed in these locations, measures should be designed to mechanically prevent unexpected restart. Learn more about the Fortress Solution in this article.
Sheet Metal Coiling in Steel Processing
Safe access is required frequently in normal operation of the metal coiling process. Safe & control I/O can help to automate machinery and keep operators safe during whole body access.
Steel Manufacture – Safe Access to Machinery
Which risk reduction measures can be applied to safe access to machinery used in Steel Manufacture?
Paper / Pulp – Recycling Facility
Recycling processes that involve machining paper & pulp can create dust, dirt and often require heavy duty wash-down procedures to clean machinery and remove byproducts.
Paper Machine Safety and Preventing Machine Restart – Roller / Winder
In paper production, access to machinery is required on a frequent basis. Whilst performing access, it is crucial to have measures which prevent unexpected restart to keep operators safe from harm.
Rolling Mills: Hot and Cold Rolling Applications
Rolling mills can be highly hazardous without controlled access and measures to prevent unexpected restart. How can Fortress help?
