Mobile concrete pump YG series

indoorfor constructionfor tunnel

Overview
A cantilever secondary structure concrete pump is designed for pouring secondary structural elements such as columns, lintels and door frames in locations that are difficult to access. It increases pouring efficiency by up to 70% compared with manual handling and reduces labour and time costs.

Key Advantages

• Durability: High‑strength alloy materials for the pump body resist deformation under heavy loads.
• Advanced hydraulic system: Precision control valves maintain constant pressure and minimise pipe blockages.
• Factory testing: Each unit undergoes a 48‑hour continuous operation test before shipment.
• After‑sales support: Global spare‑parts delivery and technical guidance to support long‑term operation.

Applications

• High‑rise secondary structure: Precise pouring for columns and lintels in multi‑storey buildings.
• Tunnel reinforcement: Suitable for confined tunnel spaces to spray fine‑stone concrete onto reinforcement surfaces.
• Water conservancy works: Fine‑stone mortar repair for dams and related structures.
• Indoor leveling: Fast laying of floor‑heating leveling layers and other interior leveling tasks.

Customer Success Case
In a large apartment project in Mexico, five YG‑500 units were used to cover 5 m floor heights. The contractor reported a 300% increase in work efficiency: tasks that previously required 20 workers were completed by 4 operators, with improved concrete consistency compared with manual pouring.

Working Principle
The pump uses a hydraulic piston system: a motor drives a hydraulic pump that generates pressure to push concrete through the pipeline. The cantilever hopper allows tilting to receive concrete from mixers at various angles and supports smooth flow of higher‑density aggregates.

Maintenance Tips

• Wash after use: Flush hopper and pipes with water immediately after operation to prevent concrete hardening.
• Check hydraulic fluid: Maintain oil level and cleanliness.
• Grease moving parts: Regularly lubricate the tilting mechanism and wheels.

FAQ (selected)

• Is the pump easy to maintain? Yes; daily rinsing of hopper and pipes and periodic hydraulic oil changes ensure reliable operation.
• What is the difference between electric and manual tilting for the YG-400? Electric tilting enables button control of hopper angle and reduces labour; manual tilting is simpler and suited to budget‑limited projects.
• What is the maximum stone diameter this pump can handle? Designed for fine‑stone concrete with aggregates from 5 mm to 16 mm.
• Can this be used for indoor floor heating? Yes; suitable for indoor leveling and mortar transport.
