Pile Extraction Using a Crane Suspended Vibratory Hammer - KOBELCO and APE
The vibratory method of installation and extracting piles began to be used on the industrial scale in 1949, and crane-suspended vibratory hammers are designed to drive and extract all types of piles such as sheets, tube casings, beams, and more. This technique is commonly employed for large scale construction projects such as harbors, airports, railways, bridges, and is also utilized for infrastructure projects in urban environments such as pipelines and other utility works.
