Schwing Service Built for the Next 8,000 Pumping Hours On-site

From hopper flush and rock-valve baseline to 1000-hour boom pin gauges — Schwing keeps concrete boom pumps and line pumps earning on the pour schedule with mean-time-to-repair targets under 18 hours on contracted sites.

Pre-delivery Commissioning

Hydraulic flow test, rock-valve seat seating, boom fold sequence check and outlet-pressure transducer zeroing before the concrete pump truck leaves the yard for its first high-rise pour.

Scheduled Field PM

Hopper wear-plate inspection, cutting-ring clearance, hydraulic return-line filter swaps and Tier 4 Final emissions audits on a 250 / 500 / 1000 hour pumping cadence.

Major Overhaul & Rebuild

Rock-valve kit replacement, boom cylinder reseal, slew-ring re-grease and pipeline clamp class re-cert so resale and rental fleets stay inside pressure charts.

Interval Walkthrough

Pumping-Hour Service Timeline

Concrete pumping fleets plan PM around cubic meters placed — this timeline translates that into rock-valve and boom checkpoints supervisors can put on the pour board.

What Schwing PM Programs Do — and Do Not — Cover

Covered when interval kits match duty

250 / 500 / 1000 hour riders assume the hydraulic system pressure and aggregate class stated at commissioning. Pilot pressure logs and ISO 4406 oil samples stay meaningful only if return-line filters are swapped on cadence.

Outside published service envelopes

Continuous abrasive pours outside the rock-valve wear class, or boom pin clearance beyond load-chart limits, need a rebuild rider — not a standard PM ticket. Field MTTR targets apply when OEM kits are pre-staged at the regional hub.

Schedule a Fleet PM Audit or Rock-Valve Wear Survey

Tell us fleet size, average m³/day and boom classes on the site — we will return a service rider with interval kits and regional hub cover within five business days.

  • Rock-valve wear trending against aggregate type
  • Boom pin clearance logs for insurance audits
  • Hydraulic cleanliness program to ISO 4406
  • Emergency parts staging before continuous pours
