1, commercial concrete arm posture pump truck boom height refers to the boom all unfolds, the ground and the maximum vertical distance between the top of the boom. The main parameters for the boom height and theoretical throughput, the boom height and theoretical throughput has been serialized.

2, according to the work of commodity concrete pump export commodity concrete pressure or pumping concrete products are divided into: low voltage (2.6 5.1 MPa), medium (6.2-6.2 MPa), high-voltage (10.1 18.1 MPa) and ultra-high voltage (22.1 MPa).

3, according to the boom height is divided into: short arm (14 to 29 m), long arm (32-48 m), super long boom (52-63 – m).

4, according to the theory of throughput is divided into: small (45-88 m3 / h), medium (91-131 m3 / h), large (151-205 m3 / h).

5, according to the boom section number is divided into: 2, 3, 4, 5 knuckle arm.

6, according to the boom folding pattern can be divided into: Z fold, folding and rolling.
