Bi-County Equipment, Ronkonkoma, N.Y. had to drive sheets to form a cofferdam in East New York, N.Y.. Site of the excavation is adjacent to a railroad track, under a street bridge which is under an elevated roadway. R.Alessi Equipment mounted an APE Model 7.5 Low Headroom Hydraulic Impact Hammer on a Caterpillar excavator to solve the problem.

When Napp-Grecco Co. of Newark, NJ needed a powerful, reliable low headroom impact hammer to use with their excavator leader system, Hascal Stockstill called APE/J&M Northeast. The Marion Generating Station PSE&G job in Jersey City NJ required 45′-90′ pipe piles to be driven under low 138kV power lines 45′ high. These lines were de-energized and grounded to a short. The project engineer was concerned that a traditional crane boom could possibly touch the live wires higher up, due to mechanical issues, operator error, etc. At 7 1/2′, APE Model 7.5 Low Headroom Hydraulic Impact Hammer is the shortest on the market, making it the perfect choice for Napp-Grecco’s application. Says 1456 pile driving foreman Vic Ruckstuhl, “The APE 7.5 has been a great hammer for us. It’s the ideal hammer for our leader system.”

Napp-Grecco Co. is a nationally recognized pipeline and underground specialty contractor. Founded 50 years ago, Napp-Grecco’s reputation is based upon getting the most difficult jobs done in the pipeline, petrochemical, and utility construction fields.

R. Alessi Equipment based right here in Mount Vernon, New York, will be the national distributor of the ROBOVIB, APE’s new robotic vibro. The ROBOVIB is mounted on an excavator and can articulate to pick and drive H piles and sheets. Alessi has always been APE’s excavator mounting specialist. APE technology and innovation linked with Alessi’s experience-a winning combination.

HF Darling of Williamsville, NY just got some good news… No they didn’t save a bunch of money by switching to Geico… What they did do was increase production on the new Geico office building in Buffalo, NY by switching to a new J&M Model 82 Hydraulic Impact Hammer. The J&M Model 82 uses the same chassis as the J&M 115 HIH, except the ram weight is reduced to 8,200 lbs. This gives the 82 HIH 32,800 ft/lbs of energy.

Darling was driving 10×42 H-Piles for this project. Since full energy was not needed, Darling was able to utilize the fully adjustable stroke control on the J&M 82 HIH and dial in the needed energy to match the parameters of this specific job.

This versatility allows all J&M hammers to be utilized on jobs with different pile types and capacities.

When Bob Anttonen and Bob Branston of Simpson & Brown, Cranford, NJ needed to drive 71″ diameter, 2″ wall, 105′ long caissons for IMTT, they called APE Northeast. APE supplied a model 600 Vibro, affectionately dubbed “Super Kong”, with the patented Quad Beam clamping system which grabs the caisson at 90 degree intervals. The configuration successfully drove all 4 cans for this phase of the job in 1 day.

The second phase involved driving 2 84″ diameter 1.5″ wall 110′ long caissons over existing 72″ caissons.

Simpson & Brown traces its roots back to 1671 when the Brown brothers came over from Liverpool. Years of experience make Simpson & Brown one of the most respected pile driving contractors around.

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.

When Tony Cardoso and Tony Alves of Cruz Construction, Holmdel, NJ needed a small vibro to drive 24″ wide flat sheets for a circular cofferdam, APE NE got the call. The APE 50 Vibro was the tool of choice for its power versus weight, as the next phase of the job involves quite a long reach. The Pompton Lakes Dam job is an Army Corps of Engineers flood remediation project.

Mike Mergentime of Merco, Inc. called APE for all of his pile driving equipment needs on the Rt. 202/Washington Ave. Bridge job in Boonton, NJ. An APE 200 Vibro, a D25-32 Diesel Hammer, “King Kong”, and a J&M Model 70 Hydraulic Impact Hammer were all used on this very difficult job.

Alessi Equipment in APE’s dealer for all excavator-mounted equipment. Judlau Construction needed an impact hammer for a low headroom application in Brooklyn, NY. Alessi Equipment mounted an APE 7.5 (only 7.5 feet tall) hammer on a Komatsu PC300LC excavator. Judlau completed the job ahead of schedule!

Ferreira Construction is pictured driving 14″ H-piles with an APE D25-32 diesel impact hammer. The job involves the construction of a new bridge (Rt.1) over Conrail railroad tracks. A GRL representative monitoring the pile driving operation commented on how efficiently the hammer operated.
