in stopes developed
Deebar has introduced Winch-Com which it says
provides – for the first time – a robust and reliable
verbal communication device for use in mining
stopes. Currently in stopes, workers have to be
in close vicinity to talk to each other or use other
means of communication (air whistles) but these
signals are often misinterpreted by workers.
According to Deebar, the Winch-Com eliminates all
of these problems. Workers can now verbally communicate with each
other easily using the system, eliminating miscommunication and
resulting in fewer accidents. In case of emergencies – for example, a
fall of ground incident – alarms can be rung through theWinch-Com,
which will result in a quicker response time to accidents.
The new unit is a small and compact version of the tried and tested
Wallcomm/Polycom unit, which is extensively used in the mining
industry.
The Winch-Com is a two-wire intercom system with battery
backup. The housing is manufactured in a DMCmaterial which is then
fitted in a stainless steel tamper-proof housing with a canopy. It is
IP65 rated which means it is protected against the entry of dust and
water which makes it suitable for stope environments.
The unit is fitted with a built in charger with NiCad batteries, with a
standby time of approximately eight hours. The transmit and receive
levels are adjustable to eliminate any background noise. An unlimited
number of intercoms can be used on a system, which has a tone calling
and paging facility and operates using a supply voltage of 525 V AC.
