Advantages of CHOWA VIBRO Model HV-250W

  • Having a big allowance for the loads, CHOWA Vibrating units have tenacious feature against hard soil.
    Centrifugal force of 703kN makes much bigger capacity of driving compared with equivalent models.
    The weight of Hanger of Vibro itself designed more heavier and it makes bigger Driving force of the point sectional area of pile or sheet pile against ground Resistance.
    Engine, Hydraulic Motor and Hydraulic Pump are selected to make maximum Performance of their capacity.

  • Less fuel consumption, by our Energy-Saving system of Power units.
    (Saving around 30% compared with normal type)

  • Better durability of Vibration Rubber. (Hanger)

  • Long time operation is available by the cooling system of vibration unit.

  • By adopting the closed circuit of hydraulic system, smaller hydraulic tank become available and make less oil feverishness and further more take effect of brake when stopping Vibro hammer.

  • Low Noise Design
    Design knowhow and high manufacturing technology for Gears, achieved low noise level from the Gear.
    By covering most of vibrating parts by the hanger, achieved more effective sound-proof.
    Installed sound-proof materials inside the Hanger and made less noise.
