Soilmec has added new features to its SM22 microdrilling rig to improve productivity and safety in tunnelling applications.
The new rod and casing loader, articulated boom and kinematics have been developed in response to customer demand, according to Soilmec.
The kinematic changes allow the rig to drill horizontally at the tunnel face and the slewing ring offers a 4.4m horizontal radius.
The new automatic loader has also been attached to the mast and can handle rods and casings up to 2m in length and 114mm in diameter for rods and 152mm in diameter for casings. The loader has a service rack that feeds the automatic loader.
