Groundscrew Piling Machine Design
Budget: ₹1,500 – ₹12,500 INR
I am repurposing a Tata Hitachi TMX20 mini-excavator into a compact groundscrew piling rig dedicated to inserting helical pile screws on rural construction sites. I already have the base machine; what I need from you is a fabrication-ready design package that turns it into a reliable installer.
The core challenge is engineering the boom attachment, drive head mount, hydraulics, and structural reinforcements so the TMX20 can torque helical screws cleanly into mixed soils without excess strain or instability. Your design must respect the machine’s existing hydraulic capacity yet maximise screw insertion speed and accuracy in off-grid locations where service support is limited.
Absolute must-haves:
• Detailed 3D CAD models and fabrication drawings for every new bracket, frame, and torque arm
• Hydraulic circuit diagrams showing added valves, hoses, and flow requirements that mate with the TMX20’s pump and controls
• Torque and structural calculations proving the assembly can safely install standard helical piles within the excavator’s tipping limits
• A concise build manual specifying materials, welding standards, and any off-the-shelf components (drive head, adapters, safety cut-outs) so a local workshop can manufacture without guesswork
• Step-by-step installation sequence that lets my crew mount and demount the kit in the field
I work mostly with Inventor, SolidWorks, and AutoCAD, so deliverables in any of those formats will slot straight into our workflow.
If you have prior experience designing piling rigs or hydraulic auger systems for minis, please share a brief example. I am ready to move the moment I see confidence that the TMX20 can be transformed into an efficient helical pile installer.
