In cofferdam construction, using vibratory hammers for pile driving and extraction is more efficient than excavator hammers, significantly saving construction time. Vibratory hammers, more suitable for cofferdams, can increase the lifespan of piles by at least 70%, which helps to reduce overall construction costs. Choose our vibratory hammers for superior performance in cofferdam projects!
Our hydraulic vibro hammer series presents over 30 models, including normal frequency high frequency hydraulic vibro hammers, resonance free variable moment vibratory hammers, hydraulic vibratory hammers with eccentric mass, and tandem vibratory hammers, delivering exceptional performance for any project.
