The NEW TK2 – “A SAFE HAVEN”

ON2 designs, builds, supplies and services The TommyKnocker 2 – “ TK2 ” mobile mine refuge chamber for the underground “Hard Rock” mining industry. During a mine emergency and evacuation, the TK2 is a Safe Haven for miners who await rescue. The chamber is easy to move and relocate in underground mining applications, making it more accessible to miners. It typically includes the ON2 “Refuge One Air Centre”, making it a complete Mine Refuge System. The NEW “TK2” design has an extended airlock entryway (2 metres), which will ensure fast unobstructed access into the refuge chamber and a shrouded external battery compartment that will be capable of providing up to 96 hours of power. The TK2’s rugged, yet simple design, provides operational availability when you need it most.
