What are the lengths of concrete pump trucks?
3 Answers
There are 7 common specifications for the length of concrete pump trucks, which are 21 meters, 24 meters, 28 meters, 30 meters, 33 meters, 38 meters, 35 meters, and 37 meters. Below is the relevant introduction: 1. Boom-type concrete pump trucks: Initially, domestic boom lengths were mostly 37 meters, but in recent years there has been a trend towards longer booms. In the coming years, as demand continues to grow, concrete pump trucks with even longer booms will enter the market. 2. Delivery cylinder: Concrete 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 the wear on the delivery cylinder, concrete piston, wear plate, and cutting ring, directly extending their service life.
I've been operating concrete pump trucks for almost twenty years and have seen all kinds of boom lengths. Small pump trucks have booms around 28 meters, suitable for small construction sites like pouring concrete for one or two-story houses. Medium-sized ones come with 37 or 48-meter booms, useful in the early stages of high-rise buildings. Large pump trucks are even more powerful, with 62 or even 72-meter booms that come in handy, especially when constructing skyscrapers. You have to be careful when operating longer booms as they tend to shake and become unstable—I often remind new operators to plan their parking spots in advance. Actually, longer isn't always better; it can cause trouble in tight spaces. In daily work, boom maintenance is also crucial—rust or wear can affect extension and retraction, and this job tests your attention to detail and experience.
I run a small construction company and frequently select concrete pump trucks. Boom length truly depends on project requirements - 28-meter ones are cheaper to rent and sufficient for short-duration small jobs. The 48-meter models are more practical, slightly costlier but significantly improve efficiency. Recently I've noticed new pump trucks with over 62-meter booms in the market, capable of pouring higher floors in one go which reduces trips and saves costs, but they require larger parking spaces and worksite areas. Operator skill must be considered when choosing - beginners easily cause accidents with long booms. We usually start with used short-boom vehicles for training before upgrading. Calculating the economics is crucial, as boom length directly impacts both profit margins and safety.
