Telbit is considered the leading suppliers of Shaft Signaling equipment for the Gold and Platinum mining industry. Our Locked Bell System consists of an Onsetter, Banksman, Driver & Call Bell units, based on the popular 3-wire communications system, which forms the backbone of all communications between the surface winder and below surface levels.
The system successfully operates the world’s deepest mines ranging over 3km’s in depth. Telbit holds a patent that defines a unique multi-wire signaling platform, and is therefore the only company capable of manufacturing the Probell Signalling System.
