MR A 250

The Marini MR A 250 is a precision-engineered micropile-rig purpose-built for foundation engineering applications where accuracy and compact footprint are critical. Featuring a 250mm maximum drilling diameter and backed by 110kW of driving power, this machine delivers exceptional performance across residential retrofitting, underpinning, and slope stabilization projects. At 16000kg, the Marini MR A 250 strikes an optimal balance between structural integrity and mobility—enabling deployment on congested urban sites and restricted-access locations where conventional drilling equipment cannot operate. The rig's modular hydraulic architecture provides consistent drilling torque and penetration rates across varying soil conditions, from cohesive clays to granular deposits. Marini MR A 250 specifications emphasize operational efficiency and reduced downtime. The machine integrates advanced monitoring systems that track drilling parameters in real-time, allowing operators to optimize bit pressure and rotation speed for each strata. Sealed hydraulic circuits minimize fluid loss and environmental risk, while the reinforced mast assembly accommodates repeated micro-loading cycles without fatigue degradation. The operator cab offers ergonomic positioning and excellent sightlines, reducing fatigue during extended drilling sequences and improving safety on challenging terrain. Marini MR A 250 micropile-rig applications span geotechnical strengthening, foundation repair, and temporary earth anchoring in both civil and industrial sectors. The machine's compact chassis enables rapid repositioning between bore locations, maximizing drilling productivity per shift while minimizing site setup time and equipment rental costs. Its proven reliability across European construction projects makes it a specification choice for contractors requiring consistent, repeatable results in deep foundation work.
