In Brief
TDT inspections for concrete pumps and truck mixer pumps — external inspection every 2 years, pressure test every 6 years, post-repair inspection after every pressurised component repair. PHS Magnum: Putzmeister, CIFA, Schwing, Mecbo. TDT authorisation for repairs with welding protocols and material certificates. Tel: +48 504 788 385.
TDT Inspections for Concrete Pumps
PHS Magnum holds TDT authorisation for repair and modernisation of concrete pumps, truck mixer pumps and transit mixers on road vehicles. We prepare the vehicle, carry out all required repairs and coordinate the inspection with the TDT inspector — who comes directly to our service hall in Chorula.
Concrete pumps are classified as pressure equipment. In Poland, they fall under the supervision of the Technical Inspection Office (TDT) rather than UDT — the inspection regime differs from standard pressure vessels and requires specific documentation for every structural repair.
TDT Inspection Intervals for Concrete Pumps
| Inspection type | Interval |
|---|---|
| External visual inspection | Every 2 years |
| Detailed inspection with pressure test | Every 6 years |
| Unscheduled inspection | After any repair to a pressurised component |
Failure to maintain the inspection schedule grounds the vehicle. The unscheduled inspection after a boom weld or cylinder replacement is particularly important — it must be completed before the pump returns to service, regardless of when the next scheduled inspection falls.
Preparation Scope
- Inspection and repair of the high-pressure hydraulic system
- Inspection and replacement of cylinder rod seals
- S-valve and S-tube inspection (wear assessment, seal replacement)
- Inspection and replacement of concrete pump rubber pistons
- Repair and calibration of the control system
- Welding and repair of mechanical damage to booms and masts (TDT-certified welders)
- Compilation of welding protocols and material certificates required by TDT inspector
- Technical documentation compilation for TDT — full inspection file
Why Documentation Matters After Boom Repair
Boom arm and mast welding must be performed by TDT-certified welders. Every weld must be documented with a protocol specifying:
- Welder certification number
- Base material and filler material grades with batch certificates
- Preheat and interpass temperatures (for high-strength steels)
- Non-destructive test (NDT) results where required
Without this file, the TDT inspector cannot issue a clearance certificate, and the vehicle cannot legally operate. PHS Magnum prepares the complete documentation package as part of every boom repair.

For older or niche brands (Elba, Turbosol, other), feasibility depends on hydraulic component availability. Many hydraulic sub-systems use cross-compatible components — call us to discuss.
How to Prepare for a TDT Inspection
- Book a pre-inspection service at least 4 weeks before your certificate expires. This leaves time for parts procurement and repair if faults are found.
- Bring the TDT passport (inspection booklet) and any previous repair protocols.
- Clean the pump — the inspector needs clear access to all pressure components, boom joints and hydraulic connections.
- Check rubber pistons before arrival — heavily worn pistons will be flagged during inspection and require replacement, adding to turnaround time.
Location
PHS Magnum is located in Chorula, 4 km from motorway A4 (Gogolin junction) — a convenient stop for vehicles travelling the A4 corridor between Wrocław and Katowice, and 180 km from the German border. Concrete pumps from Germany and Austria are welcome — invoicing in EUR available.
