CONVEYANCE – O/SPEED
COS-1 is designed as a Primary Safety Circuit Conveyance Overspeed device.
Should an OVERSPEED condition of the conveyance be experienced, with the use of SIL2 rated frequency counters, magnetic inductive sensors and either a single solenoid or dual solenoid system within the hydraulic pack, the COS-1 can de-energise power to these solenoids and therefore release hydraulic pressure from the on-board braking system.
The EUC (Equipment Under Control) hydraulic circuit in turn lowers the EUC onto the designated rail braking system.
Bring the conveyance quickly to a halt, COS has been designed for the harshest of environments to ensure reliability when needed
Ensuring the safety of workers traveling below the surface is quickly becoming a priority a major priority to responsible miners
In The event there is a failure in the decent or accent controls a backup safety device is needed to prevent and accident or major injury.
The COS-1 Overspeed device is design to assist in saving lives and preventing injury
The COS-1 will display the speed at which the EUC is travelling and give indication of either healthy or tripped status of the Overspeed System.
A “Speed Monitor Selection” switch is used to interchange between which sensors and frequency counters are being displayed on the “Speed” meter.
Failure of either one or both of the magnetic inductive sensors is monitored and alarmed, and will cause the EUC to apply the on-board braking system.
If your operating without COS-1 install on your conveyances are you really protected ?
