J&M invented the 812, later to be known as the 815, in the early 1970's. The 812/815 became the most popular vibratory pile driver/extractor in the world.
The 815 was replaced in the USA by the 44. However, the 44 is too wide to fit on sheet piles used outside the USA. This is why J&M has restarted the 815 production line. A new 815 with Model 570 power unit sells for $225,000. For more information please call John Konwick or King Evarts at 412 682-4553.
