Equipment profile

Built around the project configuration

The SOILMEC SR-45 Blue Tech Plus is a compact multifunction piling rig designed for large-diameter drilling, restricted-headroom work, and alternative foundation methods from one adaptable platform. Its dedicated low-headroom arrangement can operate at a published minimum height of 8.4 m, while conventional Kelly configurations extend its use to deeper foundation work.

The rig combines up to 185 kNm of rotary torque with cylinder- and winch-crowd options, CFA packages, and a variable-gauge undercarriage. This makes it a useful model for urban sites, constrained structures, and projects that need to balance drilling capability with transport and setup requirements.
