Charmec SF 404 DA(V)


Charmec SF 404 DA(V) is the most agile ANFO charger in our offering, designed for superiorly safe and efficient face and production charging in underground mines and tunnels with up to 24 m2 cross sections and a maximum face height of 6 meters. Excellent for development charging in narrow mine orebodies and built with a short knuckle boom construction for a small turning radius and astonishing underground maneuverability, it is available with ANFO vessel options ranging from two 300 l to two 720 l vessels, providing enough volume for several faces without refueling. The machine is equipped with a safe and ergonomic FOPS/ROPS cabin and comes with a clean TIER 3 powertrain architecture. Additionally, the SF 404 DA(V) can be fitted with a high-capacity on-board compressor, ensuring maximum ANFO flow and eliminating the need for an external compressed air line.

We have gathered extensive expertise in underground charging from the launch of the first Normet charger in the 1970’s. Ever since, we have continuously developed our charging equipment and solidified our place as the world-leading manufacturer of underground explosives chargers.
