25-Point Pre-Dispatch Mechanical Audit
Every machine leaving our yards—whether sold or rented—undergoes a signed master mechanic inspection covering:
- Hydraulics & Auxiliary Circuits: Main pump flow rate, relief valve pressure, cylinder drift test, and dry quick-disconnect couplers.
- Undercarriage & Final Drives: Track link pitch, idler/roller seals, sprocket tooth profile, and final drive magnetic plug check.
- Powertrain & Aftertreatment: Cold crank compression, turbo boost, radiator pressure test, and zero active Tier-4 fault codes.
- 3D Grade Control Calibration: Trimble/Cat Grade mast sensors, boom/stick angle encoders, and laser receiver bench test.
Frequently Asked Machine Sales & Rental Questions
Can I buy a machine straight out of your rental fleet?
Yes. Every machine we carry has both a direct Sale Price and Daily/Weekly/Monthly Rental Rates. If you rent first, up to 75% of your first month rental payments can be credited toward purchase.

Yes. Our Miami and Savannah yards handle container dismantling, flat-rack securing, wash-down USDA certification, and direct Ro-Ro delivery to PortMiami, Port Everglades, and Port of Savannah.
