What are the specifications of concrete pump trucks in terms of length?
2 Answers
The body length of concrete pump trucks varies depending on different brands and types. There are seven common specifications for pump truck lengths: 21 meters, 24 meters, 28 meters, 30 meters, 33 meters, 38 meters, 35 meters, and 37 meters. Initially, domestically produced boom-type concrete pump trucks mostly had boom lengths of 37 meters, but in recent years, there has been a trend toward longer booms. Additional Information: Pump trucks use large-diameter, long-stroke delivery cylinders to increase the suction area and reduce the number of directional changes per unit time, thereby decreasing wear on components such as the delivery cylinder, concrete piston, wear plate, and cutting ring. This directly extends their service life. Maintenance methods for pump trucks should follow the requirements and procedures outlined in the maintenance manual. Daily use should include pre- and post-operation checks of relevant components. Refer to the lubrication table in the maintenance manual to ensure timely and adequate lubrication of all parts of the pump truck.
Having worked on construction sites for over a decade, the specifications of concrete pump trucks mainly depend on the boom length. Common models start from 37 meters, such as the 37m and 42m models frequently used in small construction sites, which can handle buildings of seven to eight floors—flexible and space-efficient. Then there are mid-range 52m and 56m models, convenient for covering high-rise buildings of over ten floors, offering good cost-performance and stable operation. Nowadays, high-end models include 63m, 70m, and even 72m or longer, suitable for super high-rise buildings like those with over 30 floors. However, their large size requires spacious sites, and their wide turning radius demands multi-person coordination. Many factors influence the choice: the building height determines the required boom length—shorter booms for low-rise buildings save costs; longer trucks are unsuitable for sites with poor ground bearing capacity; longer booms require high-power engines and more frequent maintenance. Price-wise, a used 37m model can be acquired for a few million, while a new 63m model costs over ten million, plus additional maintenance budgets. It's advisable to select specifications based on actual project needs to avoid waste or risks.
