Global technology company ABB is launching ABB Ability Safety Plus for hoists, a suite of mine hoist safety products that brings the highest level of personnel and equipment safety available to the mining industry. The products include Safety Plus Hoist Monitor, Safety Plus Hoist Protector and Safety Plus Brake System including Safety Brake Hydraulics. Designed in accordance with the international safety of machinery standard IEC62061, the products have been independently certified by Sweden’s research institute RISE.
ABB Ability Safety Plus for hoists includes the new ABB SIL 3 Safety Plus Brake System, which is the mining industry's first fully independently certified Safety Integrity Level 3 mine hoist brake system. SPBS will increase the safety of personnel riding mine hoists as well as the safety of the equipment, hoist and shaft infrastructure. The new SPHP provides enhanced protection for the mine hoist and mine shaft infrastructure equipment. ABB SIL 3 SPBS handles the application of the safety brakes during emergency stops and the prevention of brake lift. ABB SIL 3 SPHP monitors the speed and position of the hoists. It also monitors the instrumentation used by personnel accessing or using the hoist from different levels, for example, at gates and maintenance platforms, emergency stop buttons and remote lockout points. The ABB SIL 3 SPHP interfaces with the safety brake system to bring or keep the hoist to a safe state. It also interfaces with the drive and hoist control system.
