Selecting a concrete pump truck requires careful consideration of the nature of the concrete work, maximum delivery requirements, maximum pumping distance, building plans, pump types, and on-site conditions. The performance and structure of different pump models vary, so it's essential to not only evaluate the type of concrete being poured but also take into account construction methods, structural needs, technical specifications, site environment, and surrounding conditions. Typically, the main performance parameters of the pump should match or slightly exceed construction demands. If the capacity is too large, utilization may be low; if too small, it may fail to meet project needs and lead to premature wear of the equipment.
Construction adaptability is a key factor, as concrete pump trucks are known for their flexibility. The higher the boom height, the greater the pouring height and coverage area, which enhances adaptability. Therefore, high-boom pump trucks should be prioritized whenever possible. Pump trucks with boom lengths between 28 to 36 meters are the most common in the market, accounting for about 75% of sales. Long-arm models are becoming the mainstream for complex projects. However, when the boom exceeds 42 meters, the cost increases significantly due to chassis limitations and space constraints at the site, making them rarely used.
The number of pumps required can be calculated based on the total volume of concrete needed, the actual output per machine, and the duration of the operation. For large-scale one-time pours, it’s advisable to have some extra capacity to ensure efficiency. Additionally, a concrete mixing plant producing 100,000 to 150,000 cubic meters annually should be equipped with 2 to 3 concrete pump trucks to maintain smooth operations.
In terms of product configuration, the pump truck should be selected with a high-performance standard. If the vehicle is high-end, its components must meet corresponding quality and aesthetic standards. The power system relies entirely on hydraulic technology, so the advancement and quality of hydraulic components are crucial. In addition to engine performance, the chassis, load capacity, and overall reliability should also be evaluated.
The control system typically includes manual, wired, and wireless options. Wired controls offer ease of use, while wireless remote control allows long-distance operation. In case of electrical failure, manual operation remains a backup option. Lastly, after-sales service is vital for these specialized vehicles. Manufacturers should provide reliable support, spare parts, and technical assistance to ensure safety and operational continuity. Without proper service, any malfunction could delay the project and cause serious consequences.
