Trailer-mounted concrete pump YG series

indoor/outdoorfor tunnelnarrow-aisle

Overview
The Small Concrete Pump Machine from YG Machinery is a compact hydraulic concrete pump engineered for confined work sites and restricted-access applications. It provides continuous conveying pressure and is optimised for pumping low‑slump concrete with minimal material buildup.

Key features

• Advanced hydraulic system ensuring continuous and stable concrete delivery.
• Optimised hopper geometry to reduce material buildup and improve handling of low‑slump mixes.
• Equipped with an S‑valve designed for smoother pumping of mixtures with larger aggregates.
• Compact footprint for improved site accessibility — suitable for narrow streets, tunnels and constrained urban sites.
• Multiple model options (YG-20, YG-30, YG-40, YG-50) to match motor power, throughput and conveying distance requirements.
• Maintenance-focused design: commonly worn parts (spectacle plate, cutting ring) are easy to replace.

Performance and technical advantages
Delivers consistent conveying pressure suitable for high‑rise and continuous pumping operations. Designed for stable operation under prolonged working conditions with operator-friendly controls. Remote technical support and accessible spare parts reduce downtime and lifecycle maintenance impact.

Applications

• Tunnelling and shotcrete work.
• Bridge construction and secondary structural pours.
• Small housing projects and urban renewal where access is limited.
• Remote sites where on‑site mixing-and‑pumping reduces logistics for ready‑mix delivery.

Selected use cases (summary)

• Urban renovation: towable compact units enabling continuous rooftop or upper‑level pumping from narrow streets inaccessible to large pump trucks.
• Remote/high‑difficulty projects: mixer‑pump solutions allowing on‑site mixing and reliable pumping in difficult terrain, lowering transport costs for ready‑mix concrete.

FAQ (concise)

• Why invest in a Small Concrete Pump Machine? — It speeds up operations, reduces required labour and enables faster completion of critical pours.
• Can the pump handle various concrete mixtures? — Yes. Models are equipped with S‑valves and adapt to mixtures containing larger aggregates.
