How does a food-grade Feldbinder trailer inspection differ from a standard one?

A food-grade trailer inspection includes additional requirements: surface roughness measurement Ra ≤ 0.8 µm, verification of seal condition for compliance with Regulation (EC) 1935/2004, checks for deep corrosion or coating damage, post-inspection disinfection, and issuance of a cleanliness protocol.

How much does an annual Feldbinder trailer inspection cost?

Pricing is available on request – the cost depends on the trailer model (EUT, KIP, food-grade) and the scope of work. Contact us: +48 602 716 551.

Does a Feldbinder KIP tipping silo trailer also require a TDT inspection?

Yes. The KIP tank is classified as a pressure vessel and is subject to the same regulations as the EUT. Additionally, the hydraulic tipping cylinder and tank pivot are inspected.

TDT inspection of a silo trailer — pressure vessel tank examination

Overview

Annual Feldbinder trailer inspection covers: lower discharge assembly (discharge spout, bottom valves, seals), top hatches, tank pressure test (1.0 bar / 15 minutes), hydraulic cylinder (KIP only) and electrical installation. Food-grade Feldbinder EUT models additionally require surface roughness measurement Ra ≤ 0.8 µm and a cleanliness protocol. TDT vessel inspection: every 2 years. PHS Magnum services Feldbinder EUT, KIP and stainless steel tanks for food-industry operators.

Feldbinder Trailer Annual Inspection – Complete Guide

Feldbinder manufactures some of the most technically advanced trailers in Europe. Whether you operate a non-tipping EUT for granulates, a tipping KIP for cement and powders, or a stainless steel food-grade tanker – each requires systematic maintenance.

What Do We Check During a Feldbinder Annual Inspection?

Lower Discharge Assembly (critical on EUT models)

The Feldbinder discharge spout and bottom valves are precision components that must remain fully sealed and operational. During inspection:

Discharge spout seal integrity – pressure test: inflate to 1 bar, observe for leaks over 15 minutes
Seal condition – EPDM or silicone rubber. Hardened or cracked seals require immediate replacement
Valve operation – smooth movement, no resistance or sticking
Camlock fitting condition – cleanliness, absence of corrosion, seal integrity

Top Hatch

Seal inspection (EPDM/silicone)
Cleanliness and latch condition
No deformation of the hatch cover

Tank Pressure Test

Pressure test at 1.0 bar for 15 minutes – leak observation (gauge pressure must remain stable)
Pressure relief valve check

Hydraulic Cylinder (KIP only)

Hydraulic oil integrity (no leaks at the piston rod)
Piston rod seal condition
Correct operation verification (trailer raises and lowers in a controlled manner)

Electrical Installation

Lighting, sensors, electrical socket
