In Brief
Silo trailer breakdown on the A4 in Poland: PHS Magnum mobile service covers 100 km around Chorula — from Wrocław through Opole to Katowice and Gliwice. Response time 45–110 minutes. Roadside repairs: pneumatic valves, aeration pads, EBS diagnostics (Wabco TEBS G2/G3), brake cylinders, emergency welding. Pressure vessel cracks require towing to workshop (TDT-certified welder mandatory). Emergency: +48 602 716 551 (24/7).
A silo trailer breakdown on the road means every hour of downtime costs money. A missed delivery means lost revenue and, with a fixed-volume contract, penalty clauses. Fast mobile service at the breakdown location is worth more than the cheapest workshop you have to tow to.

What We Repair Roadside
Silo trailer pneumatics — ball and butterfly valves, Camlock fittings, pressure hoses DN80–DN100, hatch seals, aeration pads. More about pneumatic repair →
Braking system — EBS diagnostics (Wabco TEBS G2/G3, Haldex), brake cylinder replacement, relay valve repair, air suspension.
Electrics and lighting — ABS/EBS connectors, wiring damage, light and 7-pin/15-pin connector repair.
Emergency welding — cracks at brackets, frame repairs not requiring TDT documentation. Cracks in the pressure vessel — towing to workshop is mandatory (requires certified welder and TDT documentation).
When to Tow Rather Than Repair Roadside
Not all failures can be fixed on the road. Towing to workshop is necessary for:
- Cracks in the pressure vessel (welding requires TDT documentation)
- Aeration pad damage requiring chamber disassembly
- Major compressor failures
- Chassis damage requiring a lift
We can organise towing to our workshop in Chorula.
