Trailer Concrete Pump

When purchasing this machinery, we can’t only focus on price or other people’s choice. The key lies in our actual project situations. In practice, besides product parameters, we should take into account our construction environment, project needs, power matching, later maintenance costs and so on.

Rigid matching

• Ensure aggregate particle size. Small and simple trailer concrete pumps can only pump fine aggregate below 20mm. But for heavy infrastructure or harsh mixes, an S-valve concrete pump for 40mm aggregate would be a better choice.

• Evaluate your actual pouring height, horizontal laying length and construction site road conditions. The most suitable trailer concrete pump should be selected according to the actual vertical and horizontal distance to minimize pipeline resistance, prevent flash setting and ensure a smooth pour.

• An electric motor concrete pump is a preferred choice in urban areas with stable power supply systems. Electric trailer concrete pumps are more cost-effective and more environmentally friendly. In some situations without stable power supply system, such as mountainous areas, open fields, and so on, diesel engine concrete pump can avoid pumping failures.

Traction and transportation

• A torsion bar suspension and reinforced load-bearing frameare essential configurations. Given poor road conditions, if the chassis is too thin and lacks sufficient rigidity, crushed stones will easily cause major problems. Long-term uneven stress will loosen hydraulic joints and lead to oil leakage, and can even result in the wear of precision valve spools.

• A qualified concrete pump shall be fitted with a road-suitable chassis and height-adjustable traction hook to match various types of towing vehicles.

• Please don’t overlook taillights, mudguards and reflective markings. Though they seem to be insignificant accessories, they are actually essential for legal road use and cross-border transportation to avoid hefty fines.

Core hydraulic and pumping system

• Ask manufactures whether they use well-know brands such as Rexroth or Kawasaki. The hydraulic system serves as the power core of the whole machine. Low-cost units cannot withstand long-term operation, as the oil temperature rises rapidly. Once the hydraulic system cannot maintain stable working conditions, it may cause a shutdown or weak pumping power. By contrast a qualified and mature hydraulic system can maintain stable performance even in harsh working conditions.

• S-valvesand wear-resistant parts are the most vulnerable parts of the whole equipment. So, it is necessary to check whether the cutting ring and spectacle plate adopt high-hardness alloy materials.

• Heat dissipation performance directly decides whether your machine can work continuously, so you should pay more attention to effective heat dissipation area and the cooling mode of the radiator. Insufficient heat dissipation design will cause hydraulic oil to dilute rapidly at high temperatures and result in system pressure drop. Once the oil temperature exceeds the warning limit, the machine will shut down to protect itself, which will delay the entire project schedule.

After-sales response and spare parts

Make sure manufacturers include common seals and filter elements with the machine, so you won’t have to wait an entire week for international logistics just for low-cost sealing rings. Meanwhile, watch out for suppliers who provide you with non-standard joints and screws, which lock you into their brand and raise your long-term maintenance costs.

Material adaptability and material saving

• In different construction sites, aggregate quality is variable. If the equipment cannot adapt to such changes, it may lead to construction problems such as poor feeding or pipeline blockage.

• A reasonably designed hopper structure can greatly reduce residual materials after each construction operation and avoid wasting mixed concrete during washing.

Environmental adaptability

• Many construction sites in Southeast Asia and Africa suffer from extremely unstable voltage.If the motor is not equipped with a wide voltage range protection or under-voltage protection, it is easy to burn out the PCB or motor.

• There are plenty of dust particles on construction sites. If dust sneaks into an unsealed control cabinet, it can easily lead to short circuits or contactor faults in rainy and humid weather.

• Fuel sulfur content adaptability(Diesel exclusive): If the engine needs high-grade diesel which is unavailable locally, the fuel injectors are prone to clogging. To prevent this situation, you need to ask whether the manufacturer equips with a reinforced primary fuel filter.
