Product Description

AT-2000L Raise boring machine

The AT-2000L is developed and designed by our company in response to the new characteristics of underground mining processes in domestic mines. It integrates the advantages of the original rail wheel-type drilling rig technology. This model optimizes the original drilling parameters and utilizes system integration technology to design a lower overall size. The walking part adopts a tracked trailer system, transforming the longer solid vehicle body into a center-hinged steering system, combined with remote control operation, allowing for a small turning radius, flexible movement, and high safety, better adapting to the development needs of domestic mines.
