A concrete pump truck is a type of engineering machinery that integrates concrete transportation and pouring functions and is widely used in construction scenarios such as buildings, bridges, and tunnels.
Un camión bomba de hormigón es un tipo de maquinaria de ingeniería que integra funciones de transporte y vertido de hormigón y se utiliza ampliamente en escenarios de construcción como edificios, puentes y túneles.
1. Main components/Componentes principales
Chassis: Usually adopts heavy truck chassis, which has good maneuverability and carrying capacity.
Boom system: It is composed of multiple foldable boom sections (such as 3-5 sections), which are unfolded through hydraulic control to achieve flexible material distribution.
Pumping system: includes hydraulic pump, delivery cylinder, hopper and S valve (or gate valve), which is responsible for pressing concrete to the pouring point.
Hydraulic system: provides power for boom deployment and pumping operations.
Control system: Modern pump trucks mostly use intelligent remote control or cab operation to accurately control the boom and pumping speed.
2. Working Principle/Principio de funcionamiento
Loading: Concrete is unloaded from the mixer truck into the hopper of the pump truck.
Pumping:
The delivery cylinder sucks and pushes alternately, switches direction through the S valve, and presses the concrete into the delivery pipe.
The high-pressure hydraulic system pushes the concrete along the boom pipe to the pouring position.
Placing: The operator remotely controls the boom to move, achieving 360° coverage of pouring within the operating radius.
3. Classification/Clasificación
Classification by boom structure/Clasificación por estructura del auge
(1) Truck-mounted concrete pump (with boom)/
Features: The boom and pumping system are integrated on the truck chassis, which has strong maneuverability and fast deployment.
Advantages: Suitable for construction sites with frequent transfers, no additional takeover required.
Application: Commonly used in scenes that require flexible fabrics, such as building construction and bridges.
(2) Trailer concrete pump (without boom)
Features: No boom, needs to be connected to an external conveying pipeline, and is moved by a tractor.
Advantages: low cost, high pumping pressure, suitable for pouring over long distances or in fixed areas.
Application: large foundations, tunnels, and water conservancy projects.
Classification by boom length/Clasificación por longitud de la pluma
Short arm pump truck: The arm length is 20-40 meters, suitable for low-rise residential buildings and small construction sites
Medium-long arm pump truck: The arm length is 40-60 meters, suitable for high-rise buildings (20-30 floors) and commercial complexes
Super long boom pump truck: boom length 60-80+ meters, suitable for super high-rise buildings (such as more than 50 floors) and large bridges
Note:
The longer the boom, the larger the material spreading range, but the weight and cost of the vehicle also increase significantly.
Extra-long boom pump trucks (such as 72 meters) require special chassis support and are highly complex to operate.
Classification by pumping method/Clasificación por método de bombeo
(1) Gate valve pump truck
Principle: Switch the concrete flow direction through the gate.
Advantages: simple structure, easy maintenance, suitable for low-grade concrete.
Disadvantages: easy to wear and low efficiency.
(2) S valve pump truck
Principle: Use the S-shaped swing valve to switch the inlet and outlet of the conveying cylinder.
Advantages: good sealing, high pumping pressure (up to 20MPa or more), suitable for high-strength concrete.
Disadvantages: High machining accuracy requirements for the valve body.
Classification by power type/Clasificación por tipo de potencia
(1) Diesel powered pump truck/ Camión bomba con motor diésel
Features: Relying on diesel engine, strong power, suitable for field or powerless environment.
Disadvantages: loud noise and polluting emissions.
(2) Electric pump truck/Camión bomba eléctrico
Features: External power supply or battery driven, zero emission, low noise.
Application: Tunnels, indoors, and areas with strict environmental protection requirements.
(3) Hybrid pump truck/Camión bomba híbrido
Features: Diesel + electric dual mode, taking into account both environmental protection and mobility.
Classification by chassis type/Clasificación por tipo de chasis
(1) General purpose truck chassis pump truck/ Camión bomba con chasis de camión de uso general
Modified based on standard heavy-duty trucks, it is low cost and easy to maintain.
(2) Special chassis pump truck/Camión bomba con chasis especial
Designed for pump truck working conditions, with better load-bearing capacity and stability, suitable for long boom models.
Special type pump truck/Camión bomba de tipo especial
(1) High-pressure pump truck/Camión bomba de alta presión
Pumping pressure exceeds 30MPa, used in super high-rise buildings
(2) Mini Pump Truck/Mini camión bomba
The boom is short (10-15 meters) and the body is narrow, which makes it suitable for narrow construction sites (such as rural areas and old city reconstruction).
(3) Ship-mounted pump truck/Camión bomba montado en barco
Installed on ships and used for cross-sea bridges or island construction.
4. Selection suggestions/Sugerencias de selección
High-rise construction: S-valve and long-arm (over 50 meters) pump trucks are preferred.
Eco-zone: Electric or hybrid models.
Low cost requirements: gate valve trailer pump or short arm truck mounted pump.
Summarize:/Resumir:
Pump trucks of different brands (such as Sany and XCMG) have different focuses on technology and performance, and need to be comprehensively evaluated in combination with project requirements.
Los camiones bomba de diferentes marcas (como Sany y XCMG) tienen diferentes enfoques en tecnología y rendimiento, y necesitan ser evaluados integralmente en combinación con los requisitos del proyecto.
