When procuring a concrete pump truck, the most critical technical parameters are the maximum vertical reach (boom length) and the theoretical output capacity (m³/h). For large-scale infrastructure, a boom length of 56m to 62m is standard, while urban projects may only require 30m to 38m. Ensure the hydraulic system utilizes closed-loop technology for smoother switching and that the pumping pressure is sufficient for the concrete grade you intend to use. Additionally, verify the chassis brand (e.g., Isuzu, Scania, or reputable domestic brands) as it determines the vehicle's maintenance ease and longevity.
