The replaceable bolt-on wheels overcome a weak point in traditional designs that, once they seize or snap, require welding work for replacement. In the event of maintenance being necessary, the hopper also detaches from the sub-frame.
The ETG design is fabricated from 4 mm steel and has reinforced top bars. It is shot-blasted and primed prior to colour-match powder coat painting, which in itself extends the unit's working life.
Available in two hopper capacities, 0.35 m³ and 0.25 m³, the swarf bin sub-frames feature integral forklift slots allowing lifting access from all four sides.
