concrete pump mainstream technology
Domestic truck mounted concrete boom started late because the last two years have strengthened domestic enterprises technology introduction and quality control, design and development of a proprietary arm mounted concrete block making machine, technological innovation has become the domestic arm mounted concrete pump development boosters. Major component technology trends also represent the domestic arm mounted concrete pump vehicle development. Arm mounted concrete pump truck to the specifications and more comprehensive, higher grades, the direction of the cloth longer boom, boom 37m from the past to the mainstream, a gradual transition to 42 ~ 45m mainly to the direction of 47 ~ 56m . Improve equipment energy efficiency, Concrete mixing plant performance is a big trend, gradually replace the engine cooling water from the cooling air emission standards to Euro Ⅱ I mostly or Euro IV standards. Self-test, self-protection, self-adjustment and multi-sensor technology, constant power control technology and EPS / EBC and GPS technology will become the mainstream of development; while driving in will be more humane.
