The smaller universal leader mast with a usable length of app. 14 m is mounted on the carrier SR 25 T with 261 kW and a telescopic undercarriage. The motorisation is optimised for operating a DELMAG rotary head BT 100 with a torque of 100 kNm and a variable vibrator MRZV 12V and/or MRZV 17VV.
The advantages of the fixed leader mast are particularly in the high torque absorption, load capacity and the high lifting forces. This construction is suitable particularly well for static pressing with the Hydro-Press-System and for drilling works e.g. with VDW double auger head system or Kelly drilling.
The fixed leader mast SM 18/22 HD is designed in particular for double auger drilling and soil mixing application for single, twin and triple mixing systems. It is self-evident that the fixed leader mast is suited also optimally for piling and pressing.
With approx. 24 m usable length the SM 18/24 SD is the top unit of the SM series and excellent for double auger systems like VDW and DDK. Besides vibrators and auger drives also soil cutting systems can be applied for installing slurry walls.
