The new compact digging arm loader from GIA Industri has been designed for 7 m2 cross-section tunnels and offers the option of electric or diesel power. Designed to operate in tunnels with a width of 2.5 m and the same height, this wheeled loader has a loading capacity of 2.5 m3/min. The 7HR features two unique digging arm systems – digging arms or rotating backhoe – to load muck from the drift face directly onto the Häggloader’s conveyor, which fills the haulage vehicle behind with a constant supply.
