Screen the machine by video
Use a live video to check the machine’s identity and visible condition, identify defects, and decide whether an on-site or third-party inspection is needed. Add pressure, internal wear and structural details that cannot be seen clearly to the on-site or instrument inspection.
The inspection must concern a specific item in stock. Before the call, agree on the stock number, machine model, location, date, participants and desired order. Send the checklist in advance; close-ups requested on the spot and repeated demonstrations should take place only when safety conditions and the applicable manual permit.
Start with time, place, and identity
Before the operator turns to the serial number nameplate, have them first show the live date or agreed code, the surrounding site, the full machine and the stock number. Continue to the engine and main component nameplates without switching to a pre-recorded clip. If the signal drops and the session restarts, note where the sequence was interrupted.
Read the nameplate slowly and take still photos. Compare the model, serial number, engine and component markings with the quotation. A year stated by the seller remains a claim unless supported by documents or reliable nameplate conventions.
Require a genuine cold start
Before starting the engine, show the engine area, ground beneath the machine, coolant and oil condition, battery area and dashboard where safely accessible. A qualified person should determine under the applicable manual and safety conditions whether to use an infrared thermometer to help record temperatures on the relevant engine surfaces; this reading alone cannot establish that the entire engine was not prewarmed. Start the engine under the same conditions and film the start time, exhaust, idle stability, warnings and leaks.
Where the applicable manual and safety conditions permit, continue running to normal operating temperature and observe any issues that appear when warm.
Follow a complete walk-around path
Move around the machine in a fixed direction, showing the wider environment first, then close-ups. Cover the undercarriage, frame, mast or feed, boom, cylinders, hoses, rotary head or rock drill, winch, cab, guards and service points. Pause on welds, damp areas, damaged panels and missing parts rather than avoiding them.
- Front, both sides, rear, upper structure and undercarriage
- Serial numbers and component nameplates, along with every hour meter or controller display
- Cracks, reinforcement, patches of new paint, leaks and corrosion
- Track shoes, track rollers, idlers, sprockets, chains and undercarriage frame condition
- Cab controls, alarms, cameras, lights, emergency stop devices and safety guards
Operate Each Function in the Stated Order
Qualified personnel should demonstrate functions according to the applicable manual for the specific machine, only when the equipment and site safety conditions permit. For rotary piling rigs or other rotary drilling rigs, check travel, track extension and retraction, mast raising and lowering, levelling, rotary drive, feed, main and auxiliary winches and Kelly bar movement as fitted. For surface rigs, check travel, boom and feed movement, rock drill or rotary head, rod handling, compressor loading where applicable and dust collection as fitted. If movement hesitates or is abnormal, stop and check according to the manual; do not force a repeat for filming.
Where safely possible, film gauge readings during selected operations and then check for visible new leaks. An unloaded demonstration is useful but limited; state whether the rig drilled, lifted a load or only travelled around the site, and record the actual test conditions. Any loaded test must be performed by qualified personnel according to the applicable manual, only when the equipment and site safety conditions permit.
Use buyer-specified close-up shots to reduce staged evidence
During live video, you may request details not selected in advance, such as a safely accessible hose behind a panel, the bottom of the feed, a weld from another angle, the controller menu or the wire rope inside a drum; the inspection method must follow the applicable manual and site safety conditions. This helps establish that the call is live and reveal areas a prepared video may omit.
Do not ask the operator to enter unsafe areas or work without guards. If a view cannot be obtained safely, add it to the on-site inspection checklist rather than pressuring the camera operator.
Final check of defects, included items and follow-up actions
Recap all visible defects and unresolved issues. Ask the seller to confirm which Kelly bars, drill rods, drill bits, tools, manuals and spare parts are included in the price, and show them together with the stock number. Agree whether each defect is accepted, repaired, priced separately or requires further inspection.
Keep the original video recordings, still photos, participant list and written results associated with the inventory ID. GLOBMACH can organize a remote meeting and turn the issues found into the scope of an on-site inspection or a revised quote. Provide your project and destination when requesting a quote, so that the inspection covers suitability as well as basic functions.
Turn video inspections into trackable equipment records
Each record corresponds to one machine number and states the inspection date, participants, test items and video file names; record time points for the nameplate, gauges, major movements and visible defects so they can be found later. Keep the seller's verbal statements, facts visible on camera, and items requiring instruments or on-site confirmation in separate records.
For items that were not demonstrated, could not be clearly seen or could not be safely tested, explain the reason and the next inspection method. The final quote and list of included equipment should continue to refer to the same machine.
