Description
The MT3500 is a multi-track, ultra-low profile mechanized platform powered via a tethered cable with interchangeable tool heads, operated via a remote control. The major characteristic of the machine is the four-track which is individually driven by 2 motors each, for traction and swing affording maximum maneuverability in confined spaces. The tracks on the platform is also steerable to allow for shorter turning circles and crab steering
The MT3500 is designed to reach areas that would otherwise be inaccessible, thereby improving productivity while keeping miners safe by removing them from dangerous work environments characterised by abrasive rock and steep gradients.
