When buying equipment for remote mines, after-sales and spare parts must be planned in advance.

Provides equipment list, installation checklist, wiring and grounding requirements, oil line and exhaust considerations, controller instructions, maintenance intervals and recommended spare parts list.

Photos of site preparation basics, hoisting conditions, cables, grounding, ventilation and smoke exhaust, fuel lines, low-voltage power distribution, ATS or parallel interface.

Form installation inspection records, debugging precautions and a list of problems that need rectification to reduce repeated communication after the equipment arrives on site.

For units that have remote monitoring conditions or can regularly submit operating data, track operating hours, alarm records, voltage frequency, load factor, oil pressure, water temperature, and maintenance intervals.

Keep controller data, operation records, inspection photos, maintenance records and network communication conditions available; when there is no remote module, operation screenshots and on-site photos can be submitted periodically.

Form inspection records, abnormal reminders, maintenance suggestions and spare parts supplement suggestions to expose some failure risks in advance.

Engineers first determine the processing direction based on alarm codes, controller photos, on-site videos, voltage frequency, load changes, operating hours and maintenance records.

Provide equipment nameplate, fault occurrence time, alarm code, latest maintenance time, on-site video, wiring photos, oil circuit photos and load list.

Provides fault diagnosis direction, temporary processing suggestions, whether shutdown inspection is needed, and whether on-site service needs to be arranged.

First determine whether the fault affects crushing, drainage, ventilation, communications, lighting or camp power supply, and assist in adjusting load switching, off-peak starting and temporary operating sequences if necessary.

Describe the current production status, the equipment that is running, the links that must continue to be powered, the loads that can be put into operation temporarily, and the scope of operations that the on-site electrician can perform.

Formulate suggestions for production support and electricity consumption, temporary operation plans and follow-up investigation sequences to help mining areas stabilize important links such as drainage, crushing and camps.

Assist in checking spare parts models and alternatives such as filters, belts, sensors, controllers, AVRs, electrical parts, starting systems, circuit breakers, chargers, etc.

Provide unit model, engine nameplate, generator nameplate, controller model, photos of damaged parts, photos of spare parts in stock and hours of use.

Form a spare parts list, recommended inventory, replacement parts description and procurement cycle judgment to reduce the risk of buying the wrong spare parts and waiting for downtime.

When remote judgment cannot eliminate the problem, or it involves serious mechanical failure, complex electrical inspection, ATS, parallel machine, and installation safety risks, assist in arranging local engineers and spare parts.

Provide the location of the mining area, road conditions, rainy season impacts, entry safety requirements, on-site contacts, available electricians and shutdown windows.

Confirm the on-site service plan, personnel arrangements, spare parts and tools to be carried, estimated time and service fee range.

Assist in determining the warranty scope, paid services and spare parts costs based on the contract, factory documents, equipment status, operation records, maintenance status and failure causes.

Provide procurement contracts or delivery documents, operating records, maintenance records, operation conditions before and after failure, and whether there are modification, overloading or installation problems.

Form a description of processing responsibilities, cost basis and subsequent quotation basis, so that procurement, site and management know the cost structure in advance.
