Service Inspection
Committed to Quality in Every Machine
At DDH Equipment LLC, we prioritize reliability and performance in every piece of used equipment we offer. Each machine undergoes a detailed inspection to ensure it meets our high standards—so you can buy with confidence and avoid unexpected costs.
Our mission is to provide dependable, work-ready equipment that keeps you focused on the job—not on repairs.

Detailed Exterior Inspection
Frame & Undercarriage Integrity: We conduct a detailed inspection of the frame and undercarriage, checking for cracks, rust, or structural damage that may affect the machine’s long-term durability.
Component Wear Assessment: Tracks, tires, and suspension components are carefully examined for signs of excessive wear, ensuring each part is in good working order and ready for continued operation.
Structural and Wear
Inspection
Structural Condition: We perform a detailed inspection of the exterior to identify any signs of damage, rust, or wear. This includes checking for cracks, dents, and indicators of poor or insufficient maintenance.
Paint and Finish: We assess the condition of the paint and surface coatings, looking for peeling, fading, or other signs of environmental exposure that could affect the equipment’s longevity.
Operational Performance Inspection
Functionality Testing: We power up each unit and thoroughly test all primary functions to ensure smooth, reliable performance across mechanical, electrical, and hydraulic systems.
Noise Diagnostics: Our technicians monitor the machine during operation, listening for any abnormal sounds that may indicate engine, hydraulic, or component issues.
Control Panel Check: All control elements—including switches, dials, and buttons—are tested for responsiveness and full functionality, ensuring a safe and efficient operator interface.
Engine and Mechanical Systems Evaluation
Engine Health: We perform a detailed engine inspection, checking for leaks, smoke, abnormal sounds, and verifying oil level and condition—ensuring the engine runs at optimal performance.
Transmission Check: Our technicians test the transmission for smooth gear transitions and listen for any unusual noises such as grinding or slipping that may indicate mechanical concerns.
Hydraulic System Inspection: We assess the entire hydraulic system for leaks, wear, and consistent pressure, confirming reliable operation across all hydraulic functions.
Fluid and Filtration Assessment
Fluid Level Verification: We inspect all essential fluid levels—oil, coolant, and hydraulic fluids—to confirm they are within optimal ranges for safe operation.
Filter Inspection: Our team checks the condition and cleanliness of all filters, looking for recent replacements to ensure the equipment operates at peak efficiency.
Electrical and Safety Systems Check
Battery Health: We test the battery’s charge and inspect for any corrosion to ensure dependable starts and consistent operation.
Wiring Integrity: Our team examines all wiring for signs of fraying or damage that could lead to electrical malfunctions.
Lighting and Indicator Functionality: We verify that all lights and indicators are in proper working order to maintain safe and reliable operation.
Maintenance and Usage History Review
Service Record Verification: We examine maintenance logs and service records to confirm routine upkeep and check for any previously noted issues.
Comprehensive Usage History: We gather a detailed history of the equipment, including previous ownership and any major repairs, to provide a complete picture of its past performance and reliability.
Advanced Diagnostic Evaluation
Professional Inspection: Our experienced mechanics and equipment inspectors perform thorough evaluations using state-of-the-art diagnostic tools.
Detection of Hidden Issues: We utilize specialized diagnostics to identify any underlying problems that may not be evident through visual inspection alone.
