Concrete Trailer Pump

Concrete Trailer Pump (short name: Trailer Pump) is a machine mounted on a towable chassis that conveys concrete under high pressure through pipelines. It is widely used in long-distance and high-lift construction such as high-rise buildings, tunnels, and bridges.

Product Structure

Hopper System (Upper Feeding)

1. Hopper body: steel plate welded to receive concrete
2. Mixing device: mixing shaft + blades to prevent segregation and agglomeration
3. Screen grid: blocks oversized aggregates and foreign materials
4. Suction port: connected to pumping cylinders

Core Pumping Mechanism (Heart)

1. main oil cylinders: hydraulically driven to push and pull concrete pistons
2. 2 concrete delivery cylinders: wear-resistant chromeplated barrels for direct concrete pumping
3. Concrete piston: wear-resistant rubber / polyurethane for sealing and pushing
4. Main distribution valve
   • S-tube valve: mainstream type, wear-resistant, suitable for large aggregates
   • Gate valve: traditional type, suitable for small aggregates and mortar
5. Discharge port: connected to delivery pipeline

Hydraulic System

1. Main oil pump: piston pump for high-pressure oil supply
2. Hydraulic oil tank: oil storage and heat dissipation
3. Cooler: air-cooled / water-cooled for temperature control
4. Hydraulic valve group: directional valve, relief valve, throttle valve
5. Hydraulic pipelines and filters

Power System

1. Electric version
   • Motor (37–132 kW)
   • Coupling, reducer
2. Diesel version
   • Diesel engine
   • Cooling fan, air filter, diesel tank

Electrical Control System

1. PLC controller (core brain)
2. Control panel (remote + local)
3. Emergency stop button, travel switches
4. Contactors, relays, wiring harnesses
5. Wireless remote control receiver

Chassis & Frame Structure (Trailer Type)

1. Main frame: welded high-strength steel
2. Tow hitch: connected to towing vehicle
3. Tires + axles: traveling mechanism
4. Front and rear outriggers: stabilize the machine during operation
5. Guardrails, protective covers

Lubrication & Sealing System

1. Automatic lubrication pump
2. Distributor, lubrication pipelines
3. Seals, dust rings

Working Principle

1. Main hydraulic cylinder: provides power to push and pull the concrete piston.
2. Concrete delivery cylinder: sealed chamber for suction and discharge.
3. S-tube distribution valve: core reversing component that automatically switches suction / discharge channels to prevent backflow.
4. Hydraulic system: supplies high-pressure power and controls speed and pressure.
5. Electrical control system (PLC): automatic control of reversing, speed, and protection.

Core Performance Features

1. High pressure & large displacement, strong conveying capacity: Dual-cylinder hydraulic reciprocating structure delivers high pressure and large output for long horizontal and high vertical conveying, suitable for high-rises, tunnels, bridges, and complex conditions.

2. Smooth pumping, good continuity: Dual pistons work alternately with precise S-tube reversing for continuous, non-impact discharge. Concrete resists segregation, ensuring stable pouring quality and high efficiency.
3. Strong power, wide adaptability: Optional electric / diesel dual power:
   •Electric: energy-saving, low noise, eco-friendly, low operating cost
   •Diesel: no power limitation, ideal for field and remote sites
4. Precise and reliable reversing, low failure rate: PLC intelligent electric control with hydraulic reversing logic ensures fast response and smooth movement, reducing pipe blockage, impact, and wear.
5. Excellent wear resistance, long service life: Key wear parts (delivery cylinder, piston, S-tube, spectacle plate, cutting ring) use high-wear-resistant alloy for long life and low maintenance cost.
6. Compact structure, easy movement: Trailer chassis with tires, tow hitch, and support outriggers enables easy relocation and flexible layout for narrow sites.
7. Simple operation, safe and reliable: Local + wireless remote control with user-friendly interface. Multiple protections: overload, pressure, phase loss, emergency stop, ensuring stable and safe operation.
8. Convenient maintenance: Rational layout of key components, centralized automatic lubrication, large service space, quick wear-part replacement, and simple daily upkeep.

Technical Parameters

Application Scenarios

1. High-rise buildings: High-lift capacity (150–260 m) for vertical concrete delivery to residential and office floors.
2. Tunnels & subways: Long horizontal conveying (800–1200 m) for enclosed or narrow spaces.
3. Bridges & roads: For pile foundations, piers, box girders, subgrades, and base courses; diesel version for off-grid sites.
4. Water conservancy & municipal works: High-volume concrete for dams, pump stations, and wastewater plants; narrow urban sites.
5. Small & rural projects: Model HBT6013 for rural houses, small factories, and village roads; Model HBT8016 for medium factories and infrastructure.
6. Special conditions: Secondary structure, floor heating, mortar pumping; remote areas (diesel); urban noisesensitive sites (electric).

Advantage Summary

1. Economical and practical: Lower purchase, operation, maintenance, and relocation costs than truck-mounted pumps and boom pumps; high cost-performance.
2. Strong adaptability: Compact, high-capacity, and flexible power for narrow spaces, long/high lifts, and harsh environments.
3. Stable performance, flexible operation: Smooth pumping, low failures, fast deployment, and wide material compatibility to boost efficiency.

Operation Precautions

Standard operation ensures safety, long service life, and smooth pumping.

• Deploy on level, solid ground; fully extend and lock outriggers to prevent tilting.
• Check pipeline connections and seals before pumping to avoid leakage.
• Adjust pressure and flow according to concrete grade and slump; avoid overpressure to prevent blockage or burst.
• Monitor oil temperature, level, and pressure during operation; stop immediately for abnormalities.
• Ensure stable power for electric models; check fuel and oil for diesel models.
• Flush pipelines and pump with clean water after use to remove residual concrete.
• Operators must be trained; follow rules and use PPE.
• Remove pipelines, retract outriggers, and secure parts before towing.
