Hydraulic Type Vibro Hammer

ZERO SR Series

Resonance free hydraulic type high frequency Vibration Hammer

Feature

High Performance
Maximum Centrifugal Force, as driving power, boasting of 474KN(48.3t) in the series of Hydraulic type high frequency Vibration Hammers and which expanded more widely the application of construction by the ultra high frequency . Moreover because of the mechanism of the eccentric bodies, there is no decrease in amplitude even with the increase of vibration.
Low vibration, low noise and Emission controlled type
Achieved the low vibration standard for 1996
Achieved the low noise standard for 1997
Cleared the1st and 2nd emission control regulations
Highly Economica
SR series has strong points of low vibration and low noise in addition to its own application of piling of not only steel sheet piles but also H-shape sheet piles and wider steel sheet piles. So this SR series expanded the area of construction application for Vibro Hammer compare with the Press-in machine called Silent Piler which is less economical, and SR series contribute to reduce the cost of construction.
