  • Page 9: General Information Page

    GENERAL INFORMATION A. GENERAL DESCRIPTION The J&M Model 220 Hydraulic Hammer is a Free-Fall hammer. The ram is lifted by the hydraulic actuator and then allowed to free-fall, impacting the pile. The hammer has been designed to provide maximum flexibility by enabling the contractor to vary the energy range of the hammer to suit job conditions.
  • Page 10 MODEL 220 HYDRAULIC IMPACT HAMMER GENERAL INFORMATION B. MAJOR COMPONENTS (CONTINUED) The ram is a one piece high strength steel forging. The one piece construction of the ram eliminates slack in the driving system and provides maximum energy transfer to the pile. The one piece construction also eliminates the dangers of structural failure known to exist in rams constructed of separate segments.
