The ABB Ability™ NGX Hoist Monitor is compatible with all mine hoists and applications – combining safety, reliability and innovation in one cost-effective cutting-edge solution.
ABB Ability™ NGX Hoist Monitor is a subsystem consisting of one AC500 PLC mounted in a wall-mounted cabinet and associated instrumentation and relays. It handles the main speed, position, movement & direction related safety functions for hoists.
Upon detection of a hazard, it de-energizes one or more safety relays which are connected to the mine hoist safety circuit(s). The mine hoist safety circuit is used to initiate application of the hoist’s safety brakes and removal of the motor torque.
It can be installed as a stand-alone product in existing installations where there is a requirement to replace an existing speed and position monitoring system. There is minimal required interfacing with any hoist control system.
