The Automatic Boom Isolation System

Building the frontline of an underground mine is a critical part of the mining operation. The risk of inadvertent contact with moving booms and entanglement in rotating drill steels continues to be an industry wide problem when people are working with underground drill rigs. To manage this hazard, safety procedures have been implemented, but due to human factors, incidents are still occurring.

YUMARR Automation has developed an assistance system that protects the operating crew and significantly reduces the risk of human errors. JumboGuard has been designed to be retrofitted to all types of underground drilling equipment such as rock and cable bolters as well as face drill rigs.

Protect your operating crew while minimizing the risk of human error!

JumboGuard works directly with your underground drilling equipment in addition to face drill rigs.
