The pneumatic chainsaws were developed for underground mines in which timber poles are often used to support the roof – known as the hanging wall – to prevent collapses in the confined underground stopes (work areas) that follow the orebody. Tested on several South African gold and platinum mines, the Swordfish demonstrates better performance than traditional chainsaws. The chainsaws cut support poles in restricted spaces and are required to have excellent reliability and efficiency so they can remain underground for extended periods.
