Liebherr Field Service to ISO 9001 and Plant Safety Standards

Service Tiers by Jobsite Duty

Framework agreements map haul-road kilometres, lift counts and paver tonnage into measurable audit packages for equipment managers and chief engineers. Procurement teams often ask whether a single SLA can cover both crane re-certification and excavator hydraulic cleanliness; the tier table below shows how Liebherr scopes those workstreams without mixing incompatible inspection cadences. Each tier lists the documentation pack your safety officer can file with the engineer of record, including NOx logs for Tier 4 Final machines and pin-gauge records for ASME B30 cranes. When sites span multiple countries, regional parts hubs inherit the same tier definitions so mean-time-to-repair targets remain comparable across borders.

Before a service kickoff we capture operating weight classes, boom length configurations, digging depth envelopes and bucket capacity mix so technicians arrive with the correct filters, track shoes and load-chart revisions. That intake also flags whether EU Stage V or EPA Tier 4 Final aftertreatment hardware is fitted, because DPF and SCR sampling windows differ under ISO 8178 C1 guidance. Fleet managers receive a commissioning checklist that ties hydraulic system pressure setpoints to the ISO 4406 cleanliness band written into the contract.
