The common lengths of the concrete pump truck are 21 meters, 24 meters, 28 meters, 30 meters, 33 meters, 38 meters and 36 meter concrete pump. Different pump trucks will be designed according to the requirements of chassis length, width and height, mixer efficiency requirements, boom length requirements, etc.
For example, under the condition that other configurations of the 33-meter pump truck remain unchanged, optimize the boom design and adjust the overall layout, we can launch 36 meter concrete boom pump.
1. Boom height
According to the height of the boom of the pump truck, the concrete pump truck can be divided into: short boom, long boom and super long boom. Usually the length of the boom is 13-28 meters for the short boom, 31-47 meters for the long boom, 51-62 meters for the super long boom. At present, the most common pump trucks on the market are short boom and long boom.
2. Theoretical delivery volume
According to the size of the conveying volume, the pump truck can be divided into three models, such as small 44-87 cubic meters per hour, medium 90-130 cubic meters per hour, and large 150-204 cubic meters per hour.
3. Pumping pressure
The pumping pressure is the pumping concrete pressure, which is the concrete pressure at the concrete pump outlet when the pump truck is working. According to this classification method, it can be divided into four types: low pressure (2.5-5.0MPa), medium pressure (6.1-8.5MPa), high pressure (10.0-18.0MPa) and ultra-high pressure (22.0MPa).
4. Number of boom sections
According to the number of boom sections, the pump truck can be divided into four forms: 2-section boom, 3-section boom, 4-section boom, 5-section boom, 6-section boom, and 7-section boom. The most common ones on the market are 2-section boom, 3-section boom, 4-section boom and 5-section boom.
5. Drive mode
According to the different driving methods, long boom concrete pump can be divided into the following three categories: car engine drive, trailer engine drive and separate engine drive.
6. Boom folding method
There are many ways to fold the boom. According to the different folding methods, the pump truck can be divided into two types: Z-fold and roll-fold.
