Door Control Systems
Hoffman Manufacturing offers standard door control systems or custom designed controls made to fit customer specifications. All of our control systems feature Nema 4 enclosures and high quality electrical components. Each control system is also tested in house to ensure proper function and includes wiring schematics and installation instructions. Here is a look at some of the many features that are available in our door control systems.
Control systems may be a basic relay or PLC operated. Basic relay switches are essentially electronically operated, while PLC (programmable logic controller) switches involve some sort of physical input, internal logic, and physical output. Both system types have their uses, but PLC operated systems are especially useful in mining door systems because they allow you to more precisely design your door controls to meet your specific needs. You might include features such as door interlock logic, audible alerts, and lighting signalling.
Photo Eye Assemblies
Photo eye assemblies maximize safety in mining door systems by detecting objects in the doorway and safely opening the door before contact.
Radar sensors, meanwhile, can detect moving objects and signal doors to open when they detect a particular type of motion.
Cap Lamp Sensors
Similarly, cap lamp sensors can be installed to detect when personnel are coming near, and to automate door opening when personnel are near.
Rope Pull Switch
Rope pull switches, meanwhile, can be used to open and closed mining doors manually.
Door Speed Control
Control valves can help you adjust the opening and closing speed of the door wings.
We offer convenient and customizable options to suit the unique requirements of your mining door system. The door control systems we offer with our top quality mining doors ensure added security and safety for your mine.
