Quick change for Schaeff tunnelling machine

Germany-based Atlas Maschinen has developed its Schaeff ITC 120 tunnelling machine for use in projects where geological conditions are highly changeable.

The company says the patented hammer/bucket combination allows the operator to change from hammering to loading or bucket excavation within secondsto cope with different ground conditions.

The hammer is mounted on a leverage system which gives it a stroke of 600mm with a constant thrust of 4t in any direction.

The bucket has full geometry which means the full break out force can be used for excavation in soft ground and for loading the material onto the onboard conveyor.

The Schaeff ITC 210 has an operating weight of 22t and a 1t hammer for use in tunnels with a height of more than 3.2m.

Atlas Maschinen says the machine is based on a compact crawler carrier with both electric and diesel drives and one integrated on-board heavy duty conveyor.

Atlas Maschinen has also added Schaeff cutting units to its range for the trenching and tunnelling markets. Hydraulicallypowered cutters are available for use on carriers in the 2-60t operating weight range.
