Hoist duty audits · mast bolt torque logs · tip-load re-certification for flat-top, luffing and self-erecting fleets.
Project engineers and EPC reliability leads rarely accept a generic maintenance brochure. Potain structures service scopes around the duty cycle you actually run — high-rise core climbs, urban luffing arcs, residential self-erecting pads or infrastructure staging yards. Each tier names inclusions, hoist and mast audit cadence, and the documentation pack your engineer of record can file against the next jump or reconfigure window.
When you compare potain tower crane parts programs with generic aftermarket kits, ask for serial-matched hoist gearboxes, trolley wheels and anti-two-block functional test sheets. Our field teams treat crane spare parts as controlled inventory, so mean-time-to-repair stays inside contracted response windows on active sites.
| Tier | Inclusion | Boom / Hydraulic Audit | Documentation |
|---|---|---|---|
| T1 — High-rise Flat-top | 24/7 dispatch · hoist motor warranty window | Quarterly mast bolt torque & trolley rail wear | ISO 9001 audit pack + tip-load log |
| T2 — Urban Luffing Jib | Scheduled luffing winch & sheave rotation | Monthly slew-ring clearance & wind cut-out verify | Wear-rate trend chart + spare kit map |
| T3 — Self-Erecting Residential | Annual SWL re-certification | Load-chart pin gauge · anti-two-block cert | AS 2550 / ASME B30 lift-plan audit |
| T4 — Multi-crane Overlap | Anti-collision zoning commissioning support | Encoder sync, zone limit verify | Overlap dossier for EOR sign-off |
Lift counts, freestanding heights, tip-load targets and hoist duty hours are written into the service contract before the opening site visit. This avoids ambiguous “as needed” language that fails during jump planning.
ISO 4406 particle counts, brake torque samples and gearbox oil analysis establish a baseline. Results feed the tower crane parts forecast for the next overhaul cycle.
Mast pin NDT, jib clearance, anti-two-block functional tests and load-chart pin gauges are executed per AS 2550.1 / ASME B30 — with witness points for your lifting supervisor.
MTBF, MTTR and hydraulic cleanliness trends are signed by a Potain reliability lead and submitted to the client engineer of record after each service quarter.
OEM serial-matched hoist gearboxes and trolley wheels cost more upfront than generic aftermarket kits, but keep AS 2550 / ASME B30 witness packs cleaner and usually shorten mean-time-to-repair on contracted sites. Generic kits can be acceptable for non-critical idle fleets — we disclose that split so procurement can score risk, not just unit price.
Field methodology packs used on active fleets between 2021 and 2025 are available on request with redacted site identifiers.
Share your tip load, freestanding height and next jump window. We return a scoped audit outline covering parts availability, re-cert steps and documentation ownership.
