EFAS™ is the most advanced and safest “safety catch” system (hoist arresting system) available in the world today, providing a safe deceleration of a conveyance in the event of a hoist rope severance or slack rope. EFAS™ virtually eliminates the occurrence of inadvertent activation and provides safe deceleration rates with both a fully loaded cage and a single occupant. The system works equally well with steel, rope, and wood shaft guides, and can be fitted to most existing cages, requiring only minimal modification. The system is not tied to any specific cage manufacturer. Very quick and easy to reset after quarterly mine drop tests. Large cage weight and payload combinations can be accommodated, limited only by the loading capacity of a shaft’s structural steel. SIL2 rating is also available. Contact us today for more information on hoist arresting systems, mine hoist arresting systems, conveyance arresting systems, lift arresting systems, or elevator arresting systems.
The Emergency Fall Arrest System (EFASTM) is designed to arrest and support a conveyance after a rope failure scenario by using hydraulic activated clamps, onto steel, rope, and wood shaft guides in the mine shaft.
The system can be triggered electronically or mechanically from a rope monitoring device.
EFASTM consists of a number of clamps, a hydraulic power unit and an electronic activation and control system.
Each clamp is a self contained EFAS and functions independently, with no external hydraulic piping. Hydraulic piping is only required for chairing components, should a combined EFAS and chairing system be required. Each clamp will thus activate even if there is a problem with another clamp. The clamps are designed with a safety factor of 2 on holding capacity. This means that even if half of the clamps on an installation were to fail, the conveyance would still be arrested.
The number and capacity of the clamps used depend on the mass of the conveyance. The clamps are activated or triggered either by using a mechanical or PLC controlled activation system. The hydraulic power unit is used to charge the accumulators and is installed on the bank level.
