Soilmec has launched a low headroom quick conversion for its SR-45 ADV rig to enable contractors to work in low space conditions, such as under the electric power lines, bridges and existing structures.
According to Soilmec, the new concept of the rig offers good performance in cased or uncased piles and can also be used in continuous flight auger mode.
The rig has undergone some other design changes to ensure it meets efficiency demands and is now powered a Cummins QSB 6.7litre Tier 4 engine. Safety has also been improved with operator catwalks complete with handrails and LCD cameras with a cab-mounted monitor have been added for greater visibility.
The rotary head, which has a torque capacity of 185kNm, has been lightened and resized which the manufacturers says guarantees lower force losses in extraction and less obstructions on site. The crowd system is operated by a heavy-duty 2,500mm stroke cylinder with higher effective crowd and extraction force value.
In LDP configuration the height of the rig is 8.5m and allows the use of 5m long kelly bar reaching a drilling depth of 19.3m.
