C.D. Perry of Troy, NY is rebuilding a bulkhead on the Hudson River in Albany, NY. Using their own HMC Model 25 vibratory hammer (J&M Model 22-23), Perry rented a 3 ft caisson beam and 2 J&M Model 80 Caisson Clamps to drive 140 ft long, 24 in OD, 1 in wall steel pipe weighing over 34,000lbs for the bulkhead as well as 140 ft long, 16 in OD, 1/2 in wall pipe for a loading platform. The Model 25 was able to seat the pipes into the dense layer above the rock, and the pipes were then seated into the rock with an APE D36-32 diesel hammer.
