Six Signals Fleet Managers Verify Before Award

Tier 4 Final, 100% Fleet

EPA and EU Stage V certified across crawler excavator, wheel loader and dozer ranges with documented aftertreatment maps.

ISO 4406 Hydraulic Cleanliness

Every machine ships at 18/16/13 cleanliness with factory pre-flush and on-site fluid sample ports for your reliability log.

Annual Load Chart Re-cert

AS 2550 / ASME B30 inspection packages covering pin gauge, anti-two-block and slew-bearing torque for lift-capable units.

8,000 h Undercarriage Rebuild

OEM-spec track shoes, idlers, sprockets and carrier rollers replaced on a wear-survey schedule before haul-road downtime hits.

22 Quarry-belt Parts Hubs

Certified earthmoving field-service engineers staged for mean-time-to-repair under 18 hours on contracted sites.

ROPS + FOPS Cab

ISO 6395 cab noise under 75 dB with optional 360° camera package and integrated load-moment indicators where required.

Procurement & Service Questions

Procurement & Logistics

Typical PO-to-site lead time for a crawler excavator?: Standard 20–30 ton excavators ship in 12–14 weeks ex-works plus a seven-day on-site commissioning audit; custom rock buckets or long-reach sticks add 2–3 weeks.
Which Incoterms apply for overseas earthworks fleets?: FOB at major export ports is standard; CIF and DAP are available when freight consolidates with undercarriage and attachment kits.
Country compliance packs for Africa and LATAM?: EPA, CE, GOST-R and INMETRO documentation issued on request with serial-matched emissions certificates.

Service & Spare Parts

Field-service response on contracted sites?: Mean-time-to-repair under 18 hours via 22 quarry-belt regional hubs stocking hydraulic, undercarriage and attachment SKUs.
When should an undercarriage rebuild be planned?: Around 8,000 operating hours, or earlier if wear surveys show rail and sprocket wear beyond OEM limits on abrasive haul roads.
Do you support hydraulic oil cleanliness programs?: Yes — ISO 4406 sampling SOPs, return-line filter kits and cleanliness trend reports for reliability engineers of record.
